I'm lost. Did a full format but canceled at 30%.

#1 Post by koreninja »

I screwed up and accidentally formatted my external hard drive instead of my other drive. Instead of doing a quick format I did a full format but noticed what I did and hit cancel at about 30-40%, but by that time it was too late. Now the drive is asking to be formatted fully.

Anyways, is it possible to recover with a partial full format? I have no clue how to use this software but I tried and got the error "The harddisk seems too small!" which brought up quite a bit of google hits but I couldn't seem to find a solution I understood. When I hit P it gives me "Can't open filesystem. Filesystem seems damaged."

I did both a quick scan and a deep scan. Here are the results along with the log.

I have no real clue what I am doing but I followed the tutorial as best as I could and ended up with problems that it did not really explain.

Can someone please help or atleast let me know if this is a waste of time and not fixable?

The HD is a Samsung 1TB.

Thank you,
KN

Run TestDisk, Advanced, Boot, RebuildBS, List. If you can see your files, choose Write and confirm.
If it doesn't work, you can always use PhotoRec but it won't recover the original filenames.

I've had PhotoRec running for about an hour now, with 8 hours left to do and it hasn't found 1 file yet.

Is that normal?

If you are running PhotoRec on the free space of the partition, no file will be recovered
- if the format process has wipped the disk
- or if the filesystem blocksize is larger than the previous one or the alignement of the blocks is different
