Yes, thank you very much. That did help me out. Are there any kind of limitations with using SATA and sdparm? Or is it treated exactly the same way a SCSI device is? (I guess I'm asking are there certain options which are specific to SCSI devices). I really wouldn't want to loose my data from my hard drive because, because of a stupid mistake I made. Gee, didn't Hans mention at the last East side meeting that there should be some kind of Data Rescue/Recovery, committee (for lack of a better term) Would anyone be interested?
