I have heard of no reports of broken TQ on :any other drive than the original IBM DJNA, and that I could not verify :myself. I tried this on my laptop (Dell Latitude C810) running -stable just for kicks. It works fine, but things get slooooooooow. I have since commented the lines out, and everything is back to its zippy normal. Just out of curiousity, does the new ATA driver support removable devices in the Latitude media bay? That would be neato. The ATACONTROL(8) manpage would seem to suggest it, but it's not clear. BTW: This is from ATA(4): To see the devices' current access modes, use the command line: sysctl hw.atamodes which results in the modes of the devices being displayed as a string like this: hw.atamodes: dma,pio,---,pio,dma,---,dma,---, (--- = no device) And from the command line: 9:20am ghast /home/jamie %runas sysctl hw.atamodes sysctl: unknown oid 'hw.atamodes' So something isn't right here.
