SCSI 2940UW - 9gb Seagate Baracuda Long format time?

I have a couple Seagate Baracuda 9gb SCSI drives, and a Adaptec 2940UW SCSI Controller.
I started to format one of the drives with the bios control program of the Adaptec controller. The format appeared to start and run, but the Adaptec board never turned on the HD LED, and the drive didn't make any other sounds other than the normal sound it makes while runing. After about one hour I stopped the format process. It appeared to be working because the partition information was gone, and the drive was not usable in it current condition.  I then started the format again and let it run for two hours before I had to leave, so I left it running.

Questions: Should the Adaptec controller drive activity LED be on during the format process?
How long should it take to format this drive?

My thoughts are that the bios of the drive does the format, and the controller just initializes the process, so it doesn't indicate activity because it isn't actually doing the format.

Is the LED connected to the SCSI card?  I wouldn't worry about LED activity - SCSI Low level formats can take HOURS.  Just start it and let it go.

I'll second that.  Formatting a 9G drive could take 6 hours or more.  It's always tough waiting for it and wondering "how long is long enough" since they generally don't give a status report.

Start it on Friday evening and it should be done on Monday morning.  If not, then there is a problem with the drive.

BTW, the drive light is not illuminated becuase the SCSI format is handled completely in the drive.  The controller issues a "FORMAT DISK" command and then the drive goes away and does it's work.  When it's done, it reports back to the controller that the operation has completed.  So if you watched VERY closely, you might see the activity light flicker as the initial command was sent but after that (for hours and hours) there is no SCSI bus activity and hence no light.
