This partition could not be recovered, size does etc

#1 Postby Cozzyb » 31 May 2012, 12:18

Hi,

ran teskdisk on my external HDD that is two x 500gb drives in raid 1, in a Buffalo Drivestation DUO.
It was working fine until I had it plugged in when running linux and then the drive went to raw then unallocated in disk manager.

I ran teskdisk and got the error message from the title but it has found the partition which is NTFS.

so any help?

EASEUS Datarecovery found a bunch of RAW files and I can confirm these are the files I am looking for sadly, due to them all losing there name, and the limited tools of EASEUS (only shows certain formats such as jpg etc) I still need help, but thankfully I know the files are there.

Added a picture of what shows up when I run it as GPT search rather then Intel, gives more results but some look strange.

All of them in deeper analysis search say - Filesystem seems corrupt cannot show files etc.

Any suggestions what to try?

Would it be possible to repeat your diagnose in windows
If you didn't have an GPT-partition then there is no necessity to diagnose your disk using GPT.
I ran teskdisk and got the error message from the title but it has found the partition which is NTFS.

Would need more infos about your NTFS-partition.
Did you check it and press p to list your data?
Could you repeat your diagnose as far as possible and copy and paste the content of your testdisk.log in your post?
You'll find the testdisk.log in your testdisk foilder and you can open it using wordpad.

hi, the reason I did GPT is I presumed this was needed to show Ex FAT partitions, when the hard drive went unallocated then raw it was at the time an EXfat partition i.e. this is what I am seeking to replace.

As for doing the process in windows, I currently can't as my windows drive just suffered a error and failed so having to send it back, however I can scan the same and create logs the same in the linux tool, if you told me where the log was I could upload it.

ExFAT-partitions can be a kind of confusing.
It's an NTFS-Partition (partition type is NTFS and code 07) but the boot sector is exFAT.
Example from an exFAT-partition and TestDisk / Quick Search as result;
Results
* HPFS - NTFS 0 32 33 60801 15 14 976766976 <--partition
exFAT, 500 GB / 465 GiB <--boot sector

So you should look for an NTFS partition with an exFAT-boot sector.
TestDisk displays boot sector infos at the bottom of the display.
Your partition must be checked.
In case, could you repeat your diagnose?

Would it be possible to repeat your diagnose using windows?
You'll find the log in testdisk folder.
A Live CD is read only.
So it's not possible to create a log.
If you run testdisk from an usb drive, you'll find it in your folder also.
Would be ok, to open the log and copy paste the content.

I am running the actual linux program not live cd, so should be able to create a log, doing a Intel run now, will put the log up once done.
