Hard Disk Lost All Data; Log File Says Partitions Can't Be Recovered

#1 Post by Belthasar »

Hello,

I have a 500 GB external hard drive that appears to have lost the bulk of its data. I ran TestDisk's quick search, which produced the following log. Any help in what to do would be appreciated! It says that the partitions couldn't be recovered, that the file system may be damaged.

The harddisk (250 GB / 232 GiB) seems too small! (< 500 GB / 465 GiB)

Re: Hard Disk Lost All Data; Log File Says Partitions Can't Be Recovered

Do you had a single NTFS partition ?
After Deeper Search, TestDisk has found the partition

Code: Select all

MS Data                       63  488392127  488392065
     NTFS found using backup sector, blocksize=4096, 250 GB / 232 GiB
Can you try to list its files ? If it's the partition you want to recover, use the arrow key to switch this partition to P(rimary), on next screen, choose Write, confirm, Quit.

That is the partition that I am trying to recover, but attempts to list its files fail; I get a message saying that the file system may be damaged. If I followed your instruction, would writing the files allow me to view them again, even though they couldn't be previewed?

Ok, so am I to conclude that recovery is impossible, based on the information I have provided? Thanks for all of your help, both of you.

No. Other software or a professional recovery company performing a partly manual individual recovery might give better results.
