hard drive error?

[Joey Tsai <joeytsai@angband.org>]

Hi, right in the middle of my dist-upgrade-ing to xfree 4.0.1 (hurray!), I'm
getting a physical hard drive error.

My terminal says:

Setting up xfonts-100dpi (4.0.1-1) ...
md5sum: read error on stdin
dpkg: error processing xfonts-100dpi (--configure):
subprocess md5sum returned error exit status 2

the system log (at the read error, I believe) says:

Nov  3 17:05:27 corban kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }
Nov  3 17:05:27 corban kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=18817, sector=18754
Nov  3 17:05:27 corban kernel: end_request: I/O error, dev 03:01 (hda), sector 18754

If anyone has any suggestions on what to do, I'd really appreciate it.  Thanks!
