I accidentally sent this from the wrong email address the first time, |
| 2 |
not sure if it went through to the list so I'm sending it again (I |
| 3 |
apologize if it is a duplicate). |

Hi, |
| 6 |
|
| 7 |
I've got an external USB hard drive adapter that apparently have been |
| 8 |
going bad, or maybe the drive is going bad, I don't know... It has |
| 9 |
died a few times in the last week. During that time I've been burning |
| 10 |
DVDs and trying to copy all of the data off of it, but it choked with |
| 11 |
about 130gb remaining and now, after hooking up a new adapter, XFS |
| 12 |
won't mount it. :( It's full of pictures and home movies and stuff. |
| 13 |
Sadly, this drive was part of my backup strategy. The files were all |
| 14 |
consolidated on this disk, where I was sorting and organizing them |
| 15 |
into nice DVD-sized chunks. I guess I wasn't fast enough. |
| 16 |
|
| 17 |
When I try to mount, I get the "wrong fs type" message, and dmesg shows this: |
| 18 |
XFS: bad version |
| 19 |
XFS: SB validate failed |
| 20 |
|
| 21 |
When I try to run xfs_check against it, it segfaults! (!!!) |
| 22 |
|
| 23 |
# xfs_check /dev/sdf1 |
| 24 |
xfs_check: size check failed |

| 32 |

| 33 |
|
| 34 |
xfs_repair exists, but the man page says it can only be used against |
| 35 |
clealy unmounted drives... which seems kind of funny. I ran it anyway, |
| 36 |
in read-only mode, and it was unable to find the primary superblock |
| 37 |
and started scanning the disk for the secondary. I aborted it because |
| 38 |
I don't know how much torture this drive can take. |
| 39 |
|
| 40 |
When I run "less -f /dev/sdf1" i can see amongst the bits all of the |
| 41 |
names of my directories and files etc... so I am pretty sure the data |
| 42 |
is there and readable, but I can't figure out how to get XFS to go |
| 43 |
ahead and mount it so I can copy all of that stuff off and swear off |
| 44 |
USB hard drive adapters forever. :) |
| 45 |
|
| 46 |
Remember a few days ago when someone on this list posted his XFS |
| 47 |
horror story and I said I'd never had a problem with it? Yeah, I put a |
| 48 |
curse on myself for sure when I said that. :P |
| 49 |
|
| 50 |
If anyone has any ideas at all about how to go about fixing/mounting |
| 51 |
this, I will be forever in your debt. Thanks. |
