I am trying to recover a partition on my Seagate 3TB.
There is one partition spanning the entire disk.
It was formatted in windows, with EFI using default options.
Selecting The drive, choosing 'EFI' and then Analyzing, testdisk discovers a partition table of type MS Data. There is an error message showing 'number of bytes per sector mismatches 1024 (NTFS) != 512 (HD)'.
The files do list without a problem.
Writing the partition table to the disc and rebooting, shows the filesystem as RAW in windows and inaccessible. testdisk can still list the files.
test version 6.14 WIP, windows, 32 bit.
After this there are a whole lot of errors(3 shown here, about 200 of these):
