IX. EZ-SCSI UTILITY
Partitioning
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, 63sectors per track, and one cylinder per 8 MB of
available capacity.
