How to delete GPT Protective Partition

Why we need to delete GPT protective partition?

In Windows XP Professional, you cannot access or modify GPT disk, but you can convert a GPT disk to MBR by using the clean command in DiskPart, which will delete GPT protective partition and remove all data and partition structures from the disk.

Warning: The steps below will erase all data on the GPT disk, please backup your data first.

  1. You might see HD Drive in GPT status on Disk Management.
  2. Go to DOS command line (click on "Start Menu", then "Run", type in "cmd" in textbox, and hit "OK")
    • Type in "DiskPart" in command line.
    • Type in "list disk" in command line to show all disks in this machine.
    • Use "select" to set the focus to the specified partition.
      For example "select disk 1".
    • Use "clean" command to remove GPT disk from the current in-focus disk by zeroing sectors.
  3. Go back to Disk Management, you can see GPT disk is "Not Initialized" now. 
  4. Within Disk Management, right click on disk info, choose "Initialize Disk", You can see GPT disk is "Unallocated" now.
  5. Right click on disk info, choose "New Partition…", follow Partition Wizard and format it. Now you are able to use the disk in Windows XP.

    No problem…

  5. Beami1 says:

    Brilliant! Searched for ages, got loads of bullsh*t advice. Been working in IT for 20 years, never heard of diskpart. Thanks, worked a treat!

  6. Callum says:

    Hi Paul,

    Great post. After failing to intitalize disks with Vista (apparently Wetern digital has yet to create software compatible with Vista) I tried to make one GPT. Bad Idea. Disk Part helped me fix it and I will use XP to init from now on. Thanks!

  11. Neonic says:

    Thanks a lot! That was exactly what I needed.

  12. Thank you very much! That’s exactly what I’m looking for! Diskpart – something magic around us 😀

  13. andrej says:

    uhhhhh…. that hit the spot!

    after the end of fdisk with /MBR i really didn’t have to work much with partitions, but after trying MAC on a cetain disk I just didn’t have any option within Vista install to remove GPT tag from disk. After searching the google and after I found countless useles tools and advices (funny, how sata disables any chance of using good old fdisk :-)) this comes as a salvation.
    To be true, I am a little embarrased for not knowing diskpart – but in reality I never needed one until now.

    many thanks for publishing this!

  18. Paul Gu says:

    No problem all.

    Great, a lot of people find this is useful….

  19. Steed says:

    Amazing! I’ve never heard of diskpart either before. I was able to reformat MAC original HDD’s to NTFS for windows.

  20. This is Amazing and it earned a place in my folder that I call Flint Important. Been in IT for more than ten years i never heard of disk part either Well done & this is cool beans!

  21. Paul says:

    I have spent the nbest part of an hour trolling around the web trying to find how to sort this problem out.

    Found 7 ways, one of which incuded complete linux install, the rest were even worse. Then found this.

    Remind me to get you a sainthood :-)

    Thanks v much

  23. Moses says:

    I have a drive that has a 200MB partition that is “GPT Protective Partition” and the rest of the drive is 698.44 GB NTFS which is “Healthy (System, Boot…).
    If I use your method will it erase all the data on the 698.44GB partition. I jusdt want to get rid of the GPT Protective Partition without loosing my data.

  24. Peter says:

    Mac OS X Leopard creates a GPT instead of MBR on a connected USB disk. Your tip saved my day, thanks !

  25. Paul Gu says:

    It seems very powerful tip for many people.

    Amazing! After searching forums for a half hour and downloading useless apps, I finally found this post. Where have you been all my hard drive’s life?

  27. Kanyball says:

    will i lose all data from disk after that?

  28. Paul Gu says:

    Hi Kanyball,

    Yes, all data will be erased!! Backup all data in that disk to another disk before you do this.

  29. Kanyball says:

    ok any way its great tip:)

  46. zooty says:

    Thanks a ton mate. I’ve got a laptop harddrive out in an enclosure connected to my PC and it was doing my head in that I couldn’t install an OS… it only made it worse that 90% of the internet was trying to assure me that you can install vista on a GPT protected partition no worries…. my ass you can…. It totally supports it… My ass it does…

    You’re a lifesaver.

  47. phil says:

  52. Kate says:

    Done this, but now the disk doesn’t show up as a volume in the top part of disk manager (and still doesn’t show in Windows Explorer). It shows in the bottom part, but i can’t change its drive letter in the bottom part.

    I’m dealing with an external hard drive that I reformatted to use with Time Machine for my Mac (unsuccessfully) and now want to go back to using as backup for my Windows XP PC

  67. Jymmm says:

    I had a WD 1TB MyBook connected via FireWire to XP box with the same issue as all the rest (I had been using it under OSX 10.5 without a hitch – of course).

    I was about to reach for my http://sysresccd.org/ disc, but was too lazy to reboot and find this post in a google search – worked like a charm – TYVM!!!

    I too have been doing M$ for 20+ years and never heard of DISKPART (and I’m a dos/batch file junkie), so I go curious and find this article that gives more detail on the DISKPART command, it’s scripting abilities (scarry thought there), and detailed explanations of the various sub-commands:

    A Description of the Diskpart Command-Line Utility

  68. Paul Gu says:

  69. Fantastic

  70. Kyle says:

    Awesome – thanks for the tip. I had never heard of DISKPART before and I thought I was cool. Anyways, you saved me after a Mac format.

  71. Stan says:

    Let me heap my thanks on top of the rest! Saved a near-new Mac drive (and my bacon!…)

    This certainly is a great find.

    Any advice for trying to read the drive, with Win XP, before killin the partition? I am trying to retrieve the data. Thank so much! -John Q

  76. Pat says:

    Another vote of thanks. Worked to allow me to use a Mac disk in my pc.

  117. armshead says:

    Since you are going to lose all the data, why not do a Low Level Format. Always works for me and quick too as long as you don’t use the full option and do the who;e disk.

  118. Sebastian says:

    Thanks alot, I had this external WD disk lying around which my friend(who uses a Mac) had been using. Since Macs want to do everything different I could not get the disk clean! Always this 200mb partition in the way. Your article fixed the problem in 30s, thanks alot!

  119. Paul Gu says:

    armshead: Since you are going to lose all the data, why not do a Low Level Format. Always works for me and quick too as long as you don’t use the full option and do the who;e disk.

    Low Level Format is not good hard drive, needs the utility tool from the disk manufacturer, and it’s slow too …

    remember: “Low level format is always of LAST RESORT when you encounter HDD problems.”

  120. armshead says:

    The so called Low Level Format routine offered on manufacturers support disks is a perfectly acceptable method of returning a disk to its factory state. There is nothing sinister, “bad” or “last resort” about it. The Maxtor program which I used to use
    offers an option of “first 300Mb and last 100Mb only” This takes hardly any time at all.
    LLF is routinely used by sellers of second hand disks.
    The method I always use now uses Paragon Partition Manager Pro and take less than 2 minutes from start to finish, and will work on any disk whatever the format.
    Right click on the GPT disk in the list and select “view/edit sectors”
    Highlight the first byte and hold down the zero key. The program will zip through the first two blocks in seconds, Click save. Close the program. Re-open it and you have a blank disk.
    This is my “first resort”. I’m sorry if it offends Paul Gu but a thread which has attracted 120 posts obviously has plenty of people looking for a simple answer.


  121. Paul Gu says:

    Not at all Armshead, and thanks for sharing your opinion, and it’s good to know this alternative. IMO, LLF is used when the hard disk encounters hardware issue, and LLF does a lot more than DiskPart. DiskPart can still be considered as HLF and it just does the job at this point.

  122. ptc1800 says:

    Thanks for the awesome tip! Luckily I found your advice before I tried any other way of getting my HDD back to normal.

    Back up files on the system where you get GPT partition…

    Under XP, diskpart and initialize it, then hook the drive back to “GPT” system to copy files back…

    Sweet! I too like the rest of the comments haven’t heard of diskpart. Now I can be cool like you! This was the number 2 Google search for me but the first one I tried! Took all of 20 seconds to bring the drive back to reality!

  174. Thanks a Million!

    What did we do before the internets!

    My problem was that I had a drive that was previously used for Mac Time Machine so it came up as GPT Protectve Partiition.

    Your solution fixed it in seconds so once again thankyou.

    Hi, your method by far is the best and least complicated ; without installing any software.

    I bought a hard disk media player and was formated by vendor with Vista…..and got this GPT problem which was unable to access via XP.

    Media Player instruction needed the HD to be reformated to FAT32…. and was unable to access the HD until i got to see your instruction.

    Thanks a million !!!

    Hi Paul, i’ve just bought a hard disk from a pal, and it was formatted in GPT. Added in google “can’t format sata disk gpt protective partition” y fall into your site. Simple incredible, in just 30 seconds. Now my HD is being formatted to NTFS while i’m writing this text. Thanks Forever!

  216. Paul Dewhurst says:

    Was About to follow your instructions but before I did I thought I would give my XP install disk a try. My way works as well delete the partition with Windows install. Then just exit install. It changes the partition type to GP then the partition can be deleted with any partition tool. With this method no need to back up whole drive on a multi partition disk

  245. Paul Gu says:

    Backup the data to your Mac where you plugged in, then follow the steps above to re-format the disk.

  246. Andrea says:

    Thanks for your reply, Paul. The thing is it was NOT recognized by that Mac and since then, no PC is recognizing it either…

Thank you sooooo much!!!

    I wish I could join you guys but my computer is still screwed. I got this error when trying to reformat, now my hard drive is completely toasted. I’m using Hirens Boot CD v10 and have tried everything. Reseting MBR and sector0, checked disk for errors, etc.

    I use the cd bootable mini XP and enter dos. Im able to start diskpart and select and clean the disk. When i return to disk management the wizard pops up and wants me to initialize/convert. I do this but the disk still says “unknown” and to check the system log.

    Someone PLEEEASE help me!

    plz help me man

  317. Paul Gu says:

    If it’s not working in Windows 7, then try it in Windows XP.

  318. Thanks for the invaluable tip.

    I use macdrive and it locks up the disc after your done with the drive by preventing anything from changing it. I was unable to reinitialize the disk with macdrive then create a MBR through vista disk managment because windows didn’t have the permission to change the format of the disk.

    Saved my a55 a lot of support emails to macdrive, who are quite helpless with windows administration.

  319. BTW for those of you using vista you don’t need to go to the cmd prompt. just type diskpart in Start Sarch dialogue box.

I desperately don’t want to lose all the data on the hard drive as it’s all i’ve got. Thanks in advance for any advice you could give me.

    You need to get the HD back to the system where you you put your data, such as Vista, WIndows 7, or Linux… backup all your data to the local disk. Then you can use the instruction above to re-format the disk if you need to.

  371. Desperate says:

    Thanks for that, but I don’t understand how I can back it up to the local disk when my computer can’t see it? Any ideas? THANKS!

  372. Paul Gu says:

    Desperate: Thanks for that, but I don’t understand how I can back it up to the local disk when my computer can’t see it? Any ideas? THANKS!

    I’m even confused now, where did you put the data in the first place? Are you sure you have data on the disk? what type of data? what system you have used before to put these data?


    thanks a lot its work i am really very thank full to u guys.

    SWEET JESUS DAY LORD IN THE MORNING!!!!! I’ve got 4 1TB drives and this one has been giving me a TIME for a week! Like so many on here I got poor info time after time on the net and then stumbled on this! Man thanks and then some!!!!!!!! Good Day from NC!

  378. Jaime says:

    I did this. Seemed to work but now the drive in question shows as “Unallocated” and when I right click I do not get a format option or a delete partition option. Any ideas?

  379. mikitukka says:

    @ Jamie – You need to create a new partition.

    I have a question: when i do the list disk command only my primary disk is shown. I have 4 disks connected to my PC and none of them show up. I did a RESCAN and still only one disk. grrr.. oh well ill just have to wait untill i get back home to me mac :-) Oh and it was the atvUSBcreator that created this partition in the first place.

    Unfortunately diskpart does not show removable memory (USB memory stick) as a drive so will not allow you to clear GPT on these devices.

    As a note, it was a Mac using GUID that created the GPT partition table. If you set the Mac to use MBR rather than GPT it avoids the problem and you can read the key on a Windows XP machine. This was the solution in my particular case.

    Hello. I have a GPT-formatted slave HDD. My XP pro will not detect it, nor will it be accessible in the disk list in diskpart. Any advice on that? thanks in advance.

  409. Quame says:

    You are a bloody genius,I spent weeks trying to figure this out.Thanks so much.I wonder why disk manufacturers won’t add this trouble shooting.You would think they would because it’s to their benefit.

  410. Alexandra says:

    Very useful, but i have never used the command line before so I am a little weary of using the script here. Do i just type in
    select disk x
    clear disk x ?

    Will that clear whats on the actual computer or just on the ext hdd? Because the latter is all I want! Please reply asap, I need to get this done by tomorrow and noone else on the internet seems to be as idiotic or as cautious as me!
    Thanks in advance

  411. Vyce says:

    It will only clear that HDD. For example, typing “select disk D” and then “Clean disk” will only clean drive D, if you have a disk there.

  412. Paul Gu says:

    As Vyce mentioned, It will only clear that HDD.

    WOW, look at all the well deserved comments. Well, like so many others, I found a lot of bad information, mostly people guessing at ways to do it, but DiskPart took all of about 30 seconds. My favorite part is the way it doesn’t ask “Are you sure?”, god help the poor soul that “cleans” his or her boot partition by accident. LOL A true admin tool if ever there was one. Thank you!!! Rick

  423. K.O. says:

    I’m hoping someone can help me out with my issue. I have an old WD153AA hard drive that came out of a Windows 98 computer. It’s a 15gig…and I wanted to just do a quick transfer of my old data…without having to burn it all to cd’s. Bought an enclosure…and Vista recognizes the drive as a storage device..and gives me the “safely remove hardware” option. However..the drive does not show up in my list of drives in Explorer. In Admin Tools..it shows up..but no drive letter is assigned..and it won’t allow me to edit the drive…or assign a letter to it. Is it possible that XP will recognize the drive..in order for me to get my data off of it? I don’t care about the drive…would just like to retrieve the data. It was a bootable drive in the original computer…and the jumper has been changed to make it a slave. Anyone that can help with this?
    Please email to fleabear1028@yahoo.com if you have any advise. Thanks.

  424. K.O. says:

    I should add that I have a Seagate 1TB external that I have no issues with. A friend was also looking to get his data off his old computer that recently had the motherboard go down. As luck would have it..his drive is a Western Digital also. I had the same problem with his drive…so I’m wondering if it is a Western Digital issue…or something to do with the enclosure not working correctly.

    When I type in Diskpart, it only shows the primary drive. which is listed as 0. I thought am supposed to see both drives. All I see is the primary drive. This thing is really bothering me. Its a 500GB WD drive. I want to run installations for some lessons. Thanks.

  430. Dean N says:

    I believe deleting the GPT Protective partition is about choice. I have both a mac and a pc and i did format my 500gb lg external hard drive into 3 partions-mac os x(journalled), fat 32, and NTSF . All partitions were done on the mac but the NTSF(origally a fat 32 vol from the mac) was reformatted on my pc to ntsf. So everything works fine since my pc runs windows 7(not xp). The GPT partition that shows up on my pc is just 200mb, so no worries; the idea is to be able to use my ext hard disk on both the mac and pc?
    what would you advise Paul?

    I was lucky as I had bought a HDD that I found was GPT protected, so I googled for a solution and found this spot straight away – it was almost at the top of the google search, which perhaps reflects the poularity of the site? A fix, freely given, that took under a minute to complete – and otherwise I could have spent hours searching. Brilliant!

    I searched for a long time on Western Digital’s website trying to figure out how to remove one of there god damn 200MB protected partitions on my new 500GB external USB drive. Nothing… Absolutely no information on how to recover and remove that damn partition.

    Google search and bam! Your awesome advice. I also have never used DiskPart and have been playing with computers for the past 20 years.

    Sending good karma your way.

  468. James Harrison says:

    Hi Paul. It sounds like you’ve helped a lot of people out. I’m probably less techie than most so still having problems. I have bought an external hard drive with GPT Protection. When I type list disk as suggested I get a list containing my internal hard disk (c drive) and the new disk. Obviously I don’t want to wipe the C drive so how do I select the new drive only?

  469. Shekri says:

    I attempt to perform DiskPart on a USB Flash drive, however, when i type the command it show me the fixed disk only and it does not show the removable disk… my question to you, is there a way to delete the GPT Protective partition from a removable drive (USB Flash drive). your assistant in this matter is greatly appreciated… my e-mail is inclosed above.

    I have the same problem as Kristoffer!
    I have tried to plug in today my external Seagate hard drive on to an mac laptop and it showed empty!!( I have to mention a haven’t backed up my data, unfortunately)
    I gor scared and then I tried to plug it back to my pc(windows xp). It doesn’t see it, only in computer management as a ‘healthy(gpt protective partition). Is there any chance to recover my data? I have only important data there, I would be devastated to loose it all).
    Do you think that plug it in to a pc with vista could let me see and retrieve my data?

    Many thanks!


  479. Paul Gu says:


    Plug into any pc with vista or windows 7, and then backup all data on the disk first.

    Once you’re done the backup, then follow the instruction and delete the driver and format it in Windows XP. Now you will have non-gpt driver which can be used in both XP, Vista, and Windows 7.

    I used this on an external USB disk drive. However, I was using Vista running as a virtual machine in VWware on a Mac. When I entered the final ‘clean’ command, Windows instantly closed with a blue error screen. It reported closing down to avoid damage to Windows.

    This was a bit worrying at the time but when I restarted Vista (virtual machine) all was well. I went back into Vista’s Disk Management utility and the GPT protective partition had gone. Success, but others might like to know about the blue screen issue.

    Amazing, just amazing. I replaced my laptop hard drive with an SSD. now I have this 320GB hard drive sitting here. so i decided to use it to store movies so i can play it on my PS3 and XBOX 360. I tried formating it to fat32 using (swissknife, easus, partition magic etc) everything I tried would not show up on either of the systems. however it did show up on windows 7 but not windows XP. i was scratching my head FOREVER until…

    i stumbled on this website. gave it a quick go, formated to fat32 plugged it into ps3 and xbox360 and TAADAA! works perfectly.

    i guess the partitioning programs couldn’t do anything when its locked in GPT. well u know what? EFF GPT 4 LIFE.

    kudos to paul. = )

    I got 500GB Mac formatted HDD and got really worried and almost about to return to the sender loosing $$, but u made it my day.

    read 100’s on Mac-Os, Softwares, Crackers and even read we cannot use Mac formatted disk in Windows.
    u broked their tounge.
    I am going to post ur link in all the links where i read

    This is normal, those space are reserved for disk partition and file information for the rest of space.

    >This is normal, those space are reserved for disk partition and file information for the rest of space.

    Actually it’s how Windows (and Mac OSX 10.5 and earlier) reports. HDD manufacturer (and OSX 10.6) says 1GB = 1,000,000,000 bytes (1000x1000x1000) = “metric” GB but OS says 1GB = 1,073,741,824 bytes (1024x1024x1024 or 2^30) = “binary” GB. So a “500GB” HDD is really 500/1.073741824 = 465. (There is a little bit of space reserved for partition and file information but not 7%!).

    Terabyte drives are now almost 10% over-reported, since a binary TB = 1,099,511,627,776 bytes.

    Picked up a new Toshiba 500 GB external drive for cheap quite a while back and just found out it was for mac. Too late to return. Could not use on my xp nor w7 machines.

  752. Appidemic says:

    Still helping. Thanks a lot.

  753. Ken Schiff says:

  754. Thales Macchione says:

  755. Jim Khor says:

    U are great, this helps me to solve my External USB drive from wiping Mac HFS+ type (became GPT) and unable to re-create partition on XP (found no way to workaround).

    Thank you so much ^_^

  756. keith says:

    Thank you SO much! This was driving me crazy! Win7 could see the drive but XP couldn’t. Now they both can!

    I wish there was a way to do this non-destructively, but at least this works.

  765. Javier says:

    Nice. It worked like a charm.

  766. Paul says:

    Just goes to PROVE – KNOWLEDGE is POWERFUL. If ALL of us with positive comments here paid you just 10% of the wasted time and money spent on crap ‘solutions’ I suspect you would have a nice little sum to ‘play’ with. AND it goes on and on and on….obviously this is a BIG issue and so few ‘techs’ know how to deal with it?

    You are a true Internet ‘freedom fighter’…step up and get your www MEDAL.

    THANKS :-)

  767. Ilyas says:

    Thank you so much. I agree with the above post, I am surprised how many ‘techies’ have no idea.
    I lent my external HD to a friend who uses an Apple Mac. Once he finished with it,formatted it from his PC. This is when my problems started. I use Windows and now it works on windows PC.

  768. Nguyễn Thế Bình says:

    It worked. Thank you so muck!

  800. Graeme Scott says:

    Many thanks. It was a great help in replacing the crap that Windows 8 is, with Win7.

  801. James Kazoob says:

    Wow, thanks for this, I could not figure out why WIn7 would not install after I removed 8 from a brand new HP laptop. Too bad you can’t just convert the GPT partition only, I wanted to keep the recovery partitions shipped with the drive. Oh well, not possible, nuked the other partitions and converted the HD to MBR. Works fine now :)
