I noticed this as well, but forgot to look into it. I just did a google search and found/borrowed this: If you are using a kernel >= 2.6.20, all /dev/hd*s will appear as /dev/sd*s. This is a result of Linux using the libATA drivers for PATA as well as SATA from now on. from http://www.linuxquestions.org/questions/showthread.php?t=552872 It would be MUCH easier to help with your SCSI controller problems if you can do some research and identify it for us. Either pull the card and look for a model number, or if it came with the system do some research and see what model(s) of RAID controller were shipped with the system. If you can boot the system of an IDE drive and it's a PCI card try running lspci and see if you can identify it via that route. Without knowing more the answer could be several different things, and trying to think of and cover them all could be very tedious. Jason
