I'm having a problem with my hard disk. When I format my disk DOS format only recognizes 2 heads on my st225 which has 4 heads. I do not have any docs for either the drive or the controller. Could someone who has the docs send me info on the controller and the drive so I can find out what the problem is. Thanks!! Jerome mopar@unix.cis.pitt.edu

Get into debug and at the prompt(-) type in g=c800:5 and return, then follow the directions. ST225 has 4 heads, 615 cylinders, 21.4MB capacity, step pulse range 5-200usec, ave access time 65ms, recording method MFM, write precomp = 300, land zone = 615. Goodluck! Hope this helps! Oh, I just assumed you had a WD controller. An adaptec controller uses g=c800:ccc, a Konan KXP-230 controller uses g=c800:6. If this is an AT which I doubt it's a type 2 drive. -- -------------------------------------------------------- Robin Amano | robin@uhunix.uhcc.hawaii.edu UHCC | 2565 The Mall | Honolulu, HI 96822
