Sun Fire V440 disk read/write errors

My new Sun Fire V440 is showing unusually unstable behavior. I have been
setting it up and compiling a fair amount of opensource software and then
periodically running fsck to make sure all is well. each time fsck is run
there are alot of file system errors; more than I have ever experienced on
my Ultra5. The last time I ran fsck, several directories of recently
installed software were deleted; I presume errors were found in their
filesystems and fsck removed them. I have looked at the messages file in
/var/adm and find that the disks are showing read/write errors.

I need to decide 1) if these are serious, 2) if i need to rebuild from
scratch after disk reformatting, and 3) if the disks are faulty and (while
under warranty) need to be replaced.

I am also curious to know if local environmental factors can cause disk
instability like this. The V440 is temporarily on a shelf with a sun monitor
sitting on top of it and a power cord sitting next to it. Bad idea?

these are examples of the worrisome disk errors. i surmise from the serial
numbers that all 4 of the internal 36 GB disks are showing errors. I find it
hard to believe that Sun would ship 4 faulty disks.

thanks for any help
