Well, it does some sort of tagged command, but I haven't looked closer if that's tagged command queueing. The Linux tmscsim driver which is somewhat related (it also came from Tekram) supports TCQ. > I don't know much about the sym(4) driver, but it might not work the > disk as hard either. It supports TCQ and handles some of the protocol on the chip, and SRAM is widespread on sym(4) controllers (and not found on ahc(4) stuff often)... > While the disk platters might not be going bad, the electronics might be > aging and getting more sensitive to the heat. Make sure that the disk > is well vented and cooled for now, and look into replacing it soon. I'll look after that. -- Matthias Andree Encrypt your mail: my GnuPG key ID is 0x052E7D95
