<> Well, here is the summary of the replies or information I have been able to glean about general information regarding hard disk drives. My many thanks to all those who replied or whose postings I have hacked up to make this summary. I have not had a chance to pursue this any further however but some of the supplied information looks very interesting. I hope this helps. ______________________________________________________________________________ From: alberta!prakash (Prakash Bettadapur) Organization: U. of Alberta, Edmonton, AB Perhaps, The Operating System Design: The XINU approach, by Douglas Comer may be useful for the purpose. The last two chapters deal with a simple (Unix like) file system, and a simple disk driver. Prakash ______________________________________________________________________________ From: <utcsri!utzoo!aesat!bmw@utcsri> Organization: AES Data Inc., Mississauga Ont., Canada A reference: "Winchester Disks in Microcomputers" Jonah McLeod Elsevier International Bulletins, 256 Banbury Road, Oxford, OX2 7DH, England Expensive, but *highly* recommended. Includes complete discussions of technology, design decisions, market analysis and even a source listing of a disk driver for a CP/M system!

It won't tell you much about mainstream disk drives, though.

It arrived within three days of placing the call. Good work, NCR!!!
