There are 2 other drives on the HPT370 (KA7-100 MB with TY Bios) and 2 on the main mother board IDE controller. The system is currently running 2.4.3-ac14. It has been solid as a rock and I have experienced no disk problems. I don't think I have crashed in the past 4 months running a ever changing series of kernels and changing HW from time to time. Today I tried to cp a directory from /arc to /fs2, a file system on hde, the primary channel of the HPT370. The system immediately (almost, a few files were copied) froze solid. I have tried to get to the bottom of this and have determined that I can copy a 2GB test directory to every drive in the system. At first I thought that I could copy safely off /arc if it went to a drive not on the HPT370 controller. Trying to copy to a test directory to /fs (/dev/hdb) worked and copying it to /fs2 (/dev/hde) caused an almost immediate freeze. However, when I tried to cp 10GB from /arc to /fs while a tape backup (of a partition on /dev/hda) was going on it once again (almost) immediately froze the system solid. The problem seems to only relate to the 80GB Maxtor. However, I haven't yet done quite enough experiments to conclude that (gotta get real work done on the machine so the reboots forced by the freezes limit how many tests I can squeeze in in a day ) I can apparently copy data to the drive to beat the band and I have regularly accessed files on the drive (e.g., to play an mp3) but something about a mass copy is fatal. I consed up a 2.4.4-ac9 kernel and verified that the problem persists in that kernel too. Can someone point me in the right direction? I have been assuming that it is some driver issue, but that is just an assumption. Could it be the drive? It is pretty new (a few months old). Unfortunately I must leave town for a while in a few days. I'd love to get on top of this before I go if possible. I'd appreciate any hints or similar data other could provide. TIA, Dick
