Second partition missing after Windows 7 -> 10 upgrade

#1 Post by geojay »

I've recently upgraded my Shuttle PC (SZ68R5) from Windows 7 to Windows 10 and in the process, the second partition on a Seagate ST4000DM000 4TB drive has disappeared. I unfortunately can't remember the precise detail of how the drive came to be divided into two but I believe it was because the PC has a BIOS and therefore can only access partitions of a maximum size of 2TB.

I've now run Teskdisk and it seemed to find the missing second partition. I did what I thought was required to repair the partition but now, after a reboot, neither partitions are working in Windows. Instead, I have two drives, one of which reports a corrupted disk structure and the other claims to be un-formatted. I'm now out of my depth and would like to seek help before I make matters worse.

Thanks in anticipation...

The Teskdisk log now follows:

Re: Second partition missing after Windows 7 -> 10 upgrade

#2 Post by cgrenier »

Every PC have a BIOS. Your disk isn't using 4096 bytes sector and your disk is over 2 TB, you should select EFI GPT, Analyse, Quick Search, for each partition, use 'p' to list the files.
If it's ok, on next screen, choose Write, confirm, Quit and restart your computer.

Re: Second partition missing after Windows 7 -> 10 upgrade

#3 Post by geojay »

OK, my main concern is that I selected Write in the session logged above and I think I may have made my situation worse.

I've just followed your advice to select EFI GPT and when I use 'p' to list the files, I get "Can't open filesystem. Filesystem seems damaged." for each. My log for that session follows...

Thanks

Re: Second partition missing after Windows 7 -> 10 upgrade

#4 Post by geojay »

I've run it once more, with the Intel setting and it seemed to identify the second partition, certainly it listed the files I expected to see. I'm still not confident how to restore this partition and whether that can cause any more harm:

Re: Second partition missing after Windows 7 -> 10 upgrade

#5 Post by cgrenier »

After Deeper Search, use the arrow keys to switch the partitions from D(eleted) to P(rimary) to get

Code: Select all

D HPFS - NTFS 0 1 1 243200 254 63 3907024002
P HPFS - NTFS 0 32 40 267349 89 4 4294965241
P HPFS - NTFS 267349 186 38 486400 211 19 3519055872 [Backups]
On next screen, choose Write, confirm, Quit
After a reboot, run testdisk again, Advanced, select the first partition, Boot, List. If you can see your files, choose BackupBS, confirm, Quit

Hi,
I've tried to do this, however the PC won't boot with the disk attached. I unplugged the disk while the PC rebooted and then reconnected it once Windows had started. I ran the second steps as advised but following the boot screen, 'list' wasn't available. My log follows:
