I just moved my computer to another room.
When I was trying to edit a file, it just hang there and the disk made some
strange noise .
But when I killed the process and try to open the same file again,
everything seems fine.
The part of SYSLOG is shown as below:

Jan  6 03:57:28 fuzzy unix: sc0,1,0: cmd=0x2A timeout after 30 sec.
Resetting SCSI bus
Jan  6 03:57:30 fuzzy unix: dks0d1s0 (/): retrying request
Jan  6 03:57:31 fuzzy unix: dks0d6s6 (/home): retrying request


Does anybody know what happened ?

Also I noticed some time early, there're another  message :

Jan  5 17:44:02 fuzzy unix: dks0d1s1: Media error: ID CRC or ECC error,.
Block #37722 (72957)
Jan  5 17:44:02 fuzzy unix: dks0d1s1: Swap out failed blkno 0x92A8 (page
still in memory)


Does this mean my hard disk might have some problem ?

You probably have a loose connector or terminator somewhere as a
result of the move, or somebody didn't reinstall something after
the move.

The media error definitely indicates a problem on the disk.  Since this
was on a write, it is a real media error.  Whether it happened as part
of your move or not would be tough to say.  Since it is in the swap
partition, you could *carefully* run an fx wr-cmp exercise pass
over *just the swap area* to find and spare any bad blocks.  Use
the standalone fx, or run it in single user mode, being careful to
do nothing that would cause any swapping while you do the fx.
