Kris, I dunno if FreeBSD is smart enough to live with the drive blocked at 520 octets, if so then use it that way. I took an IBM 9G HD out of a StorageTek/Clariion RAID and tried every Win9x, NT, Macintosh, SGI, and Sun utility I could find for changing the block size "back" to 512. The drive would happily chug right along doing a low level format. But after it completed it was right back there at 520. I believe IBM ships drives with custom firmware for RAID OEM's with all parameters locked with the OEM's selections. Unless you can find new firmware and the utility to load it, you are probably stuck. Oh, and the drive wouldn't map out bad blocks either. After this exercise I was able to put the drive back into the RAID as a new drive, then bind it back into the RAID5. The binding process completed before I checked it the next morning. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
