I need some information to do a low-level, physical reformat of the hard disk in an ATT6300+. The system has the original 20Mb drive (ST225) and controller (Western Digital). The BIOS is v1.04 and I am running DOS3.3. Is there a routine in ROM for physical formatting the hard drive? If so, what is the starting address for running the routine with DEBUG? Or, do I need the "System Diagnostics Disk" which I don't have? If so, where can I get the disk or program? ========================================================================= Robert F.

You can initiate this with: A:\>debug -g=c800:5 if the machine locks up, reboot, and try 'g=c800:6'. One or the other works in most of the PC's I've seen. Note that several controllers will also ask you about number of cylinders, heads, write precomp, and other stuff. Try to have this info available when you start the program. Some newer ones (used with AT or 386 machines) will pick up this info from the system EEPROM, so use your setup utility (CTRL-ALT-ESC {?}) to select the correct drive type first. When in doubt, call your local clone supplier and ask about the disk characteristics. Most of those I've talked to have been extremely helpful about digging up this info. ------------------------------------------------------- "There must be some kind of way out of here."

You can also call AT&T's support hotline (800-922-0354) and ask for their free low-level format utility.
