I had a similar problem with tar a while ago. I wasn't using scsi though but just backing up files to CD and DVD. Reading the archives gave me errors, but I can't remember if they were exactly the same as yours. Memory test (compiling xorg :) revealed a memory problem which turned out to be just badly installed memory module. Reinstalling the modules solved my problem and all was fine after that.
