scsi disk troubles

By dlcox2 ·
I have an adaptec 1520b scsi adapter & 2 seagate drives.
ID 0 st51080n (1GB capacity)
ID 1 sx410800n (9GB capacity)

I can't see more than 155 MB on the 9GB drive. When I boot off a win 98 boot floppy & run fdisk drive C: is 1 GB but drive is only 155 MB!
Here is the spec sheet url's for the disks:

Anyone help me out?!

More questions than answers I guess.
1.When you run fdisk does it only show one partition of 155MB for the d-drive????
2.What BIOS is your PC using as well as operating system and file type?

The full capacity of the drive according to fdisk with or without a partition is 155 MB. There is no OS on this box yet, I hope to put novell netware 5.1 on it, if I can resolve this issue. I booted off a win98 startup floppy to set things up initially, and the above problem is what I found. The SCSI adapter is older, but so are the drives. Any other clues?

I dont think it will help, but, first I would try to set the drives for id 1 and 2. If the scsi bios loads, the card itself should take id 0. My second thought is to make sure drive 2 is jumpered to terminate.

The adaptec card takes id 7. I did try changing the termination from one drive to the other, but I get the same results regardless of which drive is last & terminated on the bus or not.

Try going into the SCSI adapter setup utility, (usually done by pressing 'alt a' at boot up).
In this menu there will be a Format utility select your 9Gb drive and format it.
You'll then have to Fdisk it again, using your win98 boot floppy, resartand start computer without CD support and format it from the DOS prompt.
Hope this works for you.

I tried the low level format, It took about 2.5 hours, but still fdisk sees only 155 mb for the disk size. I may have to use a PCI scsi adapter, like was recommended to me. Thanks for the suggestion

While running fdisk on drive C as you mention you are watching 2 partitions formated and assigned as c and d:, both residing in the first drive. Use the option 5 to change the drive.
