GPT Table problem

[MO35AB]

I have an SSD 512 gb, inside are 2 partitions one EXT4 for linux, another is NTFS for windows ( and another two other secondary partitions)
After plugging this drive into another pc, windows, I can't access the NTFS partition now, I lost the GPT table it says, using recuva or Ease US data recovery , the file system is intact, I don't wanna start from scratch by formatting this drive ( unless necessary)
if there is any trick to restoring it without format, please help.
the linux partition is working fine, might have to restore grub though :/
heard that from grub rescue, there is a way to restore the gpt table.
please help

Not sure if Recuva or Ease can fix the parititon, it job is for data recovery not fixing partitions.

I know, I'm just mentioning that the files are all there, just the table is somehow damaged or lost.

 

[Hayato213]

What did you did though, you initialize the parititon?

I put the SSD on another pc, as a secondary partition, the problem happened.

Not sure if the drive was meant to be initialized, because if it was initialized that might be your cause of problem.

what do you mean by initialized ?

Linux partitioned hdd for example PS4 HDD, Nvidia Shield HDD are not meant to be initialized on windows, I think that might have caused you problem

Sounds like your only option will be to use data recovery and recover the files to another drive. Once that's done you can reformat and copy the files back from your recovery location.

If the partitontable is corrupted get for a fix TestDisk and follow this Guide to restore the partition table inside the MBR or GPT.

• Quick guide : Run Testdisk -> [Create] -> Choose your drive -> [Intel] for MBR or [EFI GPT] for GPT -> [Analyse] -> [Quick Search] -> press Enter -> If all partitions are displayed choose [Write] else use [Deeper Search] -> Quit Testdisk

No, that's actually ok, it won't cause a problem, used it for years.

Try MiniTool Partition Wizard from MediCat and/or the other recovery tools on the MediCat drive.

That tool set will help you a lot.

Sorry, have been busy, I am trying your solution now, and WOW !! amazing !!
By selecting [write], I m just reapplying the old partitions back ? no risk is taken ??
I'll wait for your answer @Sypherone

This tool is extra for this case.
For backup and restoring porpouse, the information of the partition table is also stored in other sectors on the partions which testdisk uses for restoring the original MBR or GPT.

For testing porpouse i manipulated the MBR, hided the drive with Ustealth and/or deleted the hole information inside the MBR . And it restored the information everytime and the drive could be used normal again.
MBR Recovery test with Testdisk

Windows won't let the installer script execute, says it might contain a virus or smth, tried every trick, it won't install.

I think on the gbatemp thread https://gbatemp.net/threads/medicat-usb-a-multiboot-linux-usb-for-pc-repair.361577/post-10010119 there are people who has resolved that issue.

This can't restore the original C drive

And this MediCat won't install, at first the script started running, now the windows defender is all going crazy, it wont allow it to run, i tried to disable real time protection, its already off and for some reason wont turn on.

its done via safe mode ...
testing now

Ya, because your running Win on it which is accessing it. The drive needs to be unmounted. This can be done be running e.g. Linux from USB stick then running Testdisk.

Or yes, can be tryed per safemode

Nope, I'm using another pc, and the drive is separated from the running operating system.

Nothing, a whole day of testing, recovering, the linux partition is gone somehow, the old windows installation is somehow corrupt ???
