Be sure that your disk controller actually supports these drives. Many ST506 controllers only support N heads, where N is often 8. Some support 16 heads, but this is and ad-hoc modification of the ST506 interface. You will also neead a formatting program that allows inputting of the drive parameters and does not impose any aribtrary limits. Lastly, most of the large capacity 5.25" winchesters are not available in ST506 interface, either because a different data rate is used, or the manufacturer wishes to avoid the number of heads, or seek performance limits imposed by ST506 compatibility. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
