Testdisk seems to think my drive is okay

#1 Post by Reiveth »

I have a drive's partition get lost, used testdisk to recover it and windows picked it up again, and all files where readable.
However I tried to write a file to it and it froze windows explorer, after the failed write the drive could not be seen by windows again.
Testdisk shows the drive fine, shows it's partition fine, shows it's boot sector and backup are ok, and can copy files from it although at an extremely slow pace.
I cannot however rewrite the partition, it has a write error, presumably because the drive can no longer write data.
Is there anyway I can make windows recognize this drive again so I can copy data at a faster pace, or will I have to wait days for testdisk to copy them?

There are probably bad sectors, it's why the copy is so slow and writing to disk failed.
You should clone the disk to a new empty one using ddrescue as described in https://www.cgsecurity.org/testdisk.pdf and/or copy the files.
Once the copy is done, do not use the original disk.
