the following partition can't be recovered/ filesystem damaged

#1 Post by likefireflies » 30 Mar 2018, 01:12

I am trying to recover an external hard drive that is not able to be read and Windows wants me to format it. I use it for recording music and there is data on it that I can't lose. So I began the scan, it found partitions, but on a quick scan I get,
"The harddisk (500 GB / 465GiB seems too small! (,1429 GB / 1331 GiB)nCheckthe harddisksize: HD Jumper settings BIOS detection...."
and
"The following partition can't be recovered:
Fat16>32M then the start, end, and size sectors.
After a deep scan it tells me that it is an hpfs NTFS partition (it is) and the it gives me the "can't open Filesystem. Filesystem seems damaged. I couldn't find anything in the documentation about this particular error. Am I just SOL?

here is the content of the log file:

Choose EFI GPT, not PC Intel. After Deeper Search, set the NTFS partition to P(rimary).
On next screen, choose Write, confirm, BackupBS, confirm, Quit
After a reboot, if you still can't access your files, try PhotoRec on the recovered partition.
