Disk parameters. Here's a first stab at compiling parameters of some
common disks. The information source is given in the rightmost column,
as there are some inconsistencies between the two sources. If you have
additions or updates, mail them to wendt@cs.csu.colostate.edu

They have (or had) a file called DRIVTALL.TXT (if I remember right). It was a list of about 300 different drives, SCSI, ESDI, ST-506, etc. Quite complete and detailed for information. I think it must be about a year old or so, but the information is still mostly valid Ed -- *********************************************************************** * "Alll you people are soooo superstitious......."

Mostly it's a list of what to set in your bios to make it work with a CompuAdd translating controller. A drives capacity is *competely* specified by the number of cylinders it has, multiplied by the number of heads, multiplied by the number of sectors on each cylinder (track), multiplied by the number of bytes/sector (512). Simple math shows that the entry for, lets say a Maxtor 4380 (a ~380 MB (unformatted) drive) would yield: maker drive cyls hds secs seek pre LZ WR type info Maxtor XT-4380E 306 4 17 ? 128 Compuadd capacity = 306 cyls * 4 hds * 17 sectors/track * 512 bytes/sector = 10,653,696 *Bytes* Likewise, a CDC 94186-383 (a similar 380 MB drive) also yields about 10 MB. A quick back-of-the-envelope calculation should have told that something was wrong. :-) No, what's been posted is the list of individual *controller* manufacturers recommended settings for their *translating* controllers. By the way, a quite complete list of drive parameters can be obtained from the Western Digital BBS at 714-756-8176. It includes several hundred drives (every drive I've ever looked up), and has correct descriptions of the drives. -- Rick Farris RF Engineering POB M Del Mar, CA 92014 voice (619) 259-6793 rfarris@rfengr.com ...!ucsd!serene!rfarris serenity bbs 259-7757

Take a look at a file called theref40.zip It has a massive collection of this kind of information ready to use. You can ftp it from chyde.uwasa.fi (128.214.12.3) from dir pc/doc dir.
