I've seen that report, but it's a bit of a mystery to me. Apparently the problem still happens if ADMA is disabled, and in that mode we just use the standard ata_tf_read function, so it's not clear how it could not be working on that controller but work on others.. Also I haven't noticed any SMART problems on my machine with ADMA enabled.. maybe it's drive or motherboard dependent? -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/
