Formatter and Partitioner (afdisk)
Use the DOS-based afdisk utility to partition and format SCSI hard disk drives,
Floptical drives, and magneto-optical drives. You can also use afdisk to remove
DOS and non-DOS partitions from a disk drive and to format removable media in
standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.
NOTE: Use afdisk only if the disk device is not controlled by the host adapter BIOS—
that is, if the host adapter does not have a BIOS or if its BIOS is not enabled. If the disk
device is controlled by the host adapter BIOS, use the DOS fdisk utility to partition and
format the disk device. (See the MSDOS documentation.)
Run
AFDISK from the DOS prompt only, not from the Windows MSDOS prompt.
Before you run it, be sure the disk devices you want to format and partition are
connected to the host adapter and that 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 the disk device you want to
partition, then press <Enter>.
- If the selected disk device is controlled by the host adapter BIOS, you can view
information about it but you cannot partition it with afdisk (Use the DOS fdisk
and format utilities.)
- If the selected disk device is unpartitioned, you must partition it before you can
format it. To do this, follow the instructions on the screen. (Press F1 to see an
explanation of the partitioning options.)
Information about the selected disk device appears in the lower left of the screen.
Disks smaller than 1 Gigabyte have 64 heads, 32 sectors per track, and cylinders
equal to the number of MB of available capacity. Disks larger than 1 Gigabyte
have 255 heads, 63 sectors per track, and one cylinder per 8 MB of available
capacity.
