Partition found, but write error

#1 Post by Sjeng »

Hello there. I've recently lost a partition. Windows doesn't see my G: drive anymore. I have 2 HDD's of 1TB, each has 2 partitions. I've ran TestDisk, and it sees my disks, and all partitions, but when I try to set the lost partition to either *, P or L (Primary bootable, Primary or Logical) the program can't write that to the disk. So I'm stuck there.
I tried using the partition type NONE, and when I do that, TestDisk only sees the first partition on the disk (titled GAMES), but not the other part. When I continue, I do get more partitions, 2 more actually, but I don't seem to be able to do anything further...
When selecting partition type Intel/PC, TestDisk sees both my partitions immediately, it even sees the name I have it (Media3). Both as Primary partitions. When I continue, I can set it to */P/L (or D). It doesn't matter which one I pick (obviously not D), TestDisk cannot write.
When trying to rebuild the Boot Sector, TD tells me the status is OK. Repairing the MFT also tells me it's in order (it matches the mirror MFT perfectly).

... So, if there's nothing wrong with the partition, why can't I fix it so Windows 10 sees it again. I can list all the files just fine in TestDisk, but not in Windows 10. Thanks for the help!

Are you running Testdisk with admin rights?
As there is no free space between your partitions I assume you used the GPT partition table type when you partitioned it.
Try writing in GPT mode.

Yes, ran it as administrator.

Picking GPT doesn't show any partitions...

When I continue, it starts tos can again, but extremely slow...

2 hours later, 04%... Why does it say Mac HFS? I'm not on a Mac, this is a PC. I don't think this is the solution... the PC option at least showed my the partitions and the files on them.

4% of 1000GB in 2 hours translates roughly into 6 MByte/sec. That is more than ten times too slow.

Your drive is failing.
Duplicate the drive using ddrescue as described in the manual.

You might create a smartmontools report before duplicating (does not take long at all!).
