[ale] DriveStatusError BadCRC

[Brian Pitts]

This afternoon my desktop's logs started filling with

Sep  7 19:30:17 localhost kernel: [17183013.668000] hdb: dma_intr: 
status=0x51 { DriveReady SeekComplete Error }
Sep  7 19:30:17 localhost kernel: [17183013.668000] hdb: dma_intr: 
error=0x84 { DriveStatusError BadCRC }
Sep  7 19:30:17 localhost kernel: [17183013.668000] ide: failed opcode 
was: unknown
Sep  7 19:30:17 localhost kernel: [17183013.728000] ide0: reset: success

I didn't notice this until the system slowed to a crawl, then froze when 
I tried to shutdown I restarted using SystemRescueCD and ran e2fsck 
which found a lot of errors on /home-  blocks used multiple times 
between multiple inodes, invalid counts, etc.

Here's the result of a short test with smartctl

Should I
a) run badblocks overnight and keep an eye on things in the future
b) expect drive failure in the near-term and buy a replacement immediately

I do have current backups on hda (which holds a rarely-booted copy of 
Windows) and older ones on another system.

Thanks,
Brian
