Gee, that just happened to me!  Well, actually, thanks to Linux's
*insistence* on reading the partition table, I haven't managed to
get I/O errors on anything bit sectors 0 through 7, but I am quite
sure I wasn't writing those sectors when I pulled the plug:

hda: read_intr: status=0x51 { DriveReady SeekComplete Error }
hda: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=6, sector=6
hda: read_intr: status=0x51 { DriveReady SeekComplete Error }
hda: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=6, sector=6
hda: read_intr: status=0x51 { DriveReady SeekComplete Error }
hda: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=6, sector=6
hda: read_intr: status=0x51 { DriveReady SeekComplete Error }
hda: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=6, sector=6
ide0: reset: success
hda: read_intr: status=0x51 { DriveReady SeekComplete Error }
hda: read_intr: error=0x10 { SectorIdNotFound }, LBAsect=6, sector=6
end_request: I/O error, dev 03:00 (hda), sector 6
unable to read partition table
[SNIPPED...]

You can "fix" this by writing all sectors. Although the data is lost,
the flash-RAM isn't. This can (read will) happen if you pull the
flash-RAM out of its socket with the power ON.
