dat drive recognized as removable hard drive

[Louis Larry <louis@webindonesia.com>]

Hello,

I have a SCSI tape autoloader that's capable of having 4 * 4Gig 4 mm dat
on it. Problem is that when the kernel boots, it recognize it as a
removable hard drive (/dev/sdb) instead of a tape drive. I use adaptec
2940 SCSI adapter. Pointer? Clue?
