While trying to get back up and running using my restored data, the NEW drive on Feisty started acting flaky. As I was making a copy of the data (first with cp then with rsync so I could monitor it more easily) the drive kept seeming slower and slower. I saw no relevant messages on dmesg or syslog. HOWEVER, when I cancelled the copy operation and umounted then remounted the drive, syslog showed complaints about filesystem errors and that fsck was needed. OH great.

I think I had better stop using Firewire on this system until I get this figured out. This system seemed reliable until this week.... but it's definitely not good now!

I have not re-mounted the drive, and dmesg shows no hardware errors:

twt@emonster:~$ dmesg | grep ieee

Since I'm working from a copy anyway I decided to try fsck...

twt@emonster:~$ fsck /dev/sda2
