Very interesting --- but My quick googling reveals many USB drive enclosures for both ATA and SATA but the marketers don't make mention of S.M.A.R.T . What is the brand of your enclosure. I want to look for it, in particular, and see if it claims the feature that you have discovered. Actually, on looking a little more closely, I'm not seeing any case of a single enclosure that can be used with both ATA and SATA. Do I read your post correctly - your enclosure can contain either a SATA or an ATA, and work over USB? But SMART only works when it is enclosing an ATA? -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
