Hmmm, yeah, that's bad.
I'm getting read errors in more places than I like.

I ran TechTool Pro. And the surface scan reported about 40 bad blocks halfway through.

Apparently, Retrospect will back up files and give you a error log. Alternatively, dd will do the same, but quietly? I don't know. Downloading a demo of Retrospect. Am praying that read errors aren't in too many important places.

I wonder how many are new... 'cause I know I had some bad blocks previously, but I don't recall if I backed / wiped the disk or not, or if I put it off until I finished the LiveJournal stuff (which... I haven't done anything for lately, bother..)

Ugh. My sympathies - I went through the same fun in the Spring, with some vast number of errors, probably the result of many static zaps at the last office. :-P As you've probably found out, bad sectors are normally mapped out automatically and transparently by the IDE controller, but only up to a small number - the only solution is to reformat the drive using a "write zeros" option, forcing the reconstruction of the drive's bad sector table. (Eventually, I wouldn't mind replacing the drive, but it's a 120GB model, and it still seems like we're stuck at the 160GB for now, which wouldn't be much of an improvement)

I'd very much like to see something like TechTool Pro and/or DiskWarrior included with Leopard. Recovery tools aren't something you want to have to try discovering and obtaining when you've just had a bad corruption. (And neither utility is exactly cheap)

Mmmrrr. Yeah, I think static zaps do do nasty things - I think I blame them for all my motherboard failures... Although the bad blocks... eh.

Well, you do get a CD that includes various tools upon picking up AppleCare. Or at least I did... And I think it included TechTool lite, or something like that.
