Adaptec PCM-3420, PC/104 manual Formatter and Partitioner afdisk

Formatter and Partitioner (afdisk)

Use the DOS-based afdisk utility to partition and format SCSI hard disk drivers, Floptical drivers, and magneto-optical drivers. You can also use afdisk to remove DOS and non-DOS partitions from a disk drive and to format removable media in standard disk format, OS/2 floppy format, or DOS/V (Japanese) format.

Note : Use afdisk only if the disk device is not controlled by the PCM-3420 host adapter BIOS - that is , if the PCM-3420’s BIOS is not enabled. If the disk device is controlled by the PCM-3420 host adapter BIOS, use the DOS fdisk utility to partition and format the disk device .(See the MS-DOS documentation)

Run afdisk from the DOS prompt only, not from the Windows MS-DOS prompt. Before you run it, be sure the disk devices you want to format and partition are connected to the PCM-3420 host adapter and they are powered. Then follow these steps :

1.Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk at the DOS prompt, and press Enter.

Information about your SCSI disk devices appears on the screen. (The number that appears after Target is the device’s SCSI ID.)

2.Use the arrow keys to move the highlight bar to disk device you want to partition, then press Enter.

lIf the selected disk device is controlled by the PCM-3420 host adapter BIOS, you can view information about it but you cannot partition it with afdisk (Use the DOS fdisk and format utilities).

lIf the selected disk device is unpartitioned, you must partition it before you can format it. To do this , follow the instruction on the screen. (Press F1 to see an explanation on the partition- ing options.)

Information about the selected disk device appears in the lower left of the screen. Disk smaller than 1 Gigabyte have 64 heads, 32 sectors per track, and cylinders equal to the number of Mbytes of available capacity. Disks larger than 1 Gigabyte have 255heads, 63 sectors per track, and one cylinder per 8 M Bytes of available capacity.
