I have an XT-clone (Epson Equity II, NEC-V30) with a Seagate ST-225 hard drive and Western Digital controller (WD1002). The drive was beginning to have a lot of seek-errors, so I ran a low-level format and now the drive is botched. The formatter flagged over 1000 bad sectors and I cannot create a DOS partition (disk read-error). The drive itself is fine, it formatted (with minimal bad tracks) when mounted in another system (AT-class), so the problem seems to be between the low-level formatter (which is Epson's, not from WD) and the controller. Is the phone call to WD for documentation and formatting software all that I need? More? Less? Todd Wilke wilke@cb.ecn.purdue.edu Dept. Chemical Engineering Purdue University

You can try to use a known good controller to test your drive again. There are also a number of hard disk utility packages, that support low-level format functions, in the market. (one of which, we are using a lot, is the Disk Manager by Ontrack Computer Systems Inc.) I don't have their phone number on hand, but if you like to know, I can dig it out. Qiwu Liu Univ. of KS

Check to be sure you're using a step rate within drive specifications. If the drive works properly on another controller and machine, that's a likely cause oi your problems.
