Hi folks, I'm new here and in a bit of a bind. Hoping to see the suggestion that gets me past this hurdle.

1.Trying to mount the drive results in errors (must specify filesystem type) even though it’s ext3

2.Ran fdsk on the bad device (dev/sdb)
a.Confirms linux native partition exists (ID 83 – linux native)

3.Ran ddrrescue
a.Command: sudo ddrescue /dev/sdb /dev/sdc /home/ddrescue.log
b.It ran across errors but recovered a lot of data then went back to bad
blocks and recovered some more data

4.Trying to mount /dev/sdc results in the same error #1
a.Ddrescue wasn’t able to recover the bad blocks regarding my partition

5.Off to e2fsck now
a.Ran this: sudo e2sfck /dev/sdc which resulted in error
i.Can’t read super block try alternative block locations and “bad magic number error”
b.I used testdisk to provide the super blocks numbers however
i.Sudo e2fsck <all alternative block locations> -b /dev/sdb
ii.Results in the same error

6.Using testdisk to look at my linux partition gets listed twice. The how to document for testdisk suggest if this happens, your filesystem is corrupted. The testdisk information online is a little vague per my knowledge level of this issue.

I’m at a loss on what to try next. Is this drive down for the count? Any help greatly appreciated.

/dev/sdc represents whole hard disk. You need to use partitions like /dev/sdc1. Boot from rescue disk and run fsck w/o mounting the partition.

... and the <dunce hat> goes to me! I was able to repair /dev/sdc1 and now my drive has been restored to a new drive.

Sometimes its those simple things right in front of your nose. Like adding sdc1. LOL

Thanks

Heh

No problem. Tagged as [Solved].
