IBM/Xebec HDD Controller - Low-Level Format

WARNING:	A low-level format of a hard drive will destroy
	any existing data on that drive.

The following text is applicable to all three variations of the IBM/Xebec controller.

There are three techniques available for the IBM/Xebec controllers:
1. Advanced Diagnostics Disk
2. DEBUG
3. SpeedStor

After the low-level format, you will need to perform the standard FDISK/FORMAT operations.

NOTE:	If you are using an early version of DOS (e.g. 3.3), and you see "Disk Boot failure" after using FDISK/FORMAT, then try a later version of DOS (e.g. 6.22).
	Early versions of DOS don't cope with certain areas of the hard drive being unusable.
