HDD Recovery

#1 Post by ivan » 23 May 2014, 06:58

Hi

I have a QNAP NAS which had two drives in it runninig mirror raid, and both drives have failed me for some unknown reason. I have started testdisk and analysing has been stuck on 99% for a few hours now on a 1TB HDD. Is this supposed to take this long?

Thanks

Ivan

No, it's shouldn't take as long.
Can you open the testdisk.log in Wordpad and copy the content into your next post?
You'll find the testdisk.log in your testdisk folder.

There is no log in the testdisk folder

Should I stop the current analysis and maybe try to run photorec?

Can you check the testdisk.log file again, if you finished testdisk?

If testdisk hangs, you can stop it.
Might be possible that testdisk already displays some found partitions.
If your file system is Ext3/4, you can have a try to mark them and pressing p, to have a try to list your data.
Did you run testdisk "Deeper Search"?
Otherwise you can run PhotoRec.

I found my log file, but its massive. So I have only copied in the first few pages:
