The thread about SCSI errors just stopped so I don't know what happened there. There was some thought that maybe LVM was trying to access beyond the end of the disk so you could check to see if the LV is using all the space on /dev/hdc and back it off a little so see if that helps. It may also be worth upgrading to LVM 1.0.1rc4. If it is the SCSI tape drive interfering then that's really odd because SCSI shouldnot interfere with IDE unles you have some interrupt clashes or perhaps bad cabling causing signal noise. Not very conclusive I'm afraid, but I did say I wasn't an IDE expert! patrick
