We just bought a Micropolis 1558-15 300Mbyte hard disk for our 6386E Unix box. I'm installing it as a second hard disk in the system. The unit came with a 135Mbyte. I set the drive type in the system's CMOS config RAM to 31--304 Mbyte. I then ran the Low Level Format program that comes with the 6386. It finds what looks to be the proper hard disk and proceeds to format the 15 heads and 1221 cylinders. Everything is going fine so far. I then reboot the Unix system off of the existing HDU and run the Unix FDISK program to set up a partition on the new HDU (/dev/rdsk/1s0) FDISK only sees 814 cylinders. Why???? I continued to partition the disk and even ran mkfs and mounted the new file system. Re-booting the system only reported the file system to be 150Mbytes big. I think the problem is in the FDISK or Low Level Formatter programs. Am I close??? Anyone have any ideas???? P.S. The Micropolis disk was bought from Micropolis direct, not from AT&T. -- ------------------------------------------------------------------------------- Lawrence Roney - Santa Monica College Telecommunications Department N6YFN 1900 Pico Blvd., Santa Monica, CA 90405-1628 Mail UUCP: uunet!ucla-cs!smcnet!lawrence Internet: lawrence@smcnet.smc.edu

This is the correct number of cylinders for disk type 31. You don't say what type your hard disk controller is. If it is a WD 1007A-WAH or WD 1007A-WA2, then removing jumper W8 will tell it to fake your 1221-cylinder, 34-sector disk as an 814-cylinder disk with some larger number of sectors per track. At least as of rev 1.14, the ROM BIOS is unable to handle more than about 1023 cylinders; hence the kludge. I've installed three of these drives in 16mHz 6386's (the original ones manufactured by Olivetti) with no problems. This was, however, with the drive being the only one in the machine. I don't know what removing W8 would do to your first (135mb) drive. Perhaps they are separately configurable, in which case W8 is for the first drive. If you haven't already, you also need to remove W3 to disable the PROM that's on the controller, and you need to have BIOS 1.14 or later. Send mail if the above doesn't get you going.

I've had success with installing a large hard disk (Priam 330 meg) as Unit 0 on my home-made 33 MHz 386 mahcine. I run DOS 3.3 and AT&T Unix 3.2.1. One odditiy is that DOS has to be in the first partition. I have 30 megs of DOS and 300 megs of Unix. I let the install program partition the Unix side on its own, and it broke the disk into root, usr and usr2, all of which are less than 150 megs hmmm... You do indeed need to remove jumper W8 on either the 1006 or 1007 controller. If you are using more than 36 sectors per track, the 1007 controller is needed to handle the 15 megabit/sec data rate. I didn't use the AT&T customer diagnostic disk because it didn't recognize the parameters passed back by the Priam drive. I have the 1007-V-SE2 controller that has the floppy port and ROM. The ROM has a formatter at c800:5 that sets the CMOS and formats the drive. The on-screen menu is self-explanatory. The 1007 sets the HDU type to a dummy value of 1, which looks strange but works correctly (The controller retrieves the parameters by querrying the ESDI drive). If you have the 1006 or 1007 without on-board ROM, you can call Western Digital at 800-832-4778, go through the voice mail maze and have them send you a floppy disk with WDFORMAT on it. WD is very good about sending out free documentation and is usually pretty helpful on the phone. You can also download WDFORMAT from their support BBS at 714-756-8176. If you call, have WD send you the installation and Technicala Reference Manuals for your controller; they're pretty interesting and useful. ==Bill== -- Bill Mayhew NEOUCOM Computer Services Department Rootstown, OH 44272-9995 USA phone: 216-325-2511 wtm@uhura.neoucom.edu ....!uunet!aablue!neoucom!wtm via internet: (140.220.001.001)

Why use fdisk directly? Is there a reason why you don't want to use diskadd(1)? Since diskadd does some other magic beyond what I've seen before, you may want to give it a try. (I tried partitioning and mkfs'ing by hand the first time around and had all sorts of ugly problems. Especially, watch out for labelit(1)! It seems that mkfs doesn't "take" until after labelit is run). BTW, I'm assuming that you are using the WD1007A-WA2 ESDI controller. >P.S. The Micropolis disk was bought from Micropolis direct, not from AT&T. Shouldn't matter. Just make sure that you yank the terminating resistor. The only apparent difference in the AT&T-shipped disks is the LLF. (I had one of the 300MB drives DOA, and they replaced it with one in a Micropolis factory box. Of course, it hadn't been LLFd. Ugh. Call the hotline, wait a week for the LLF disks, which they double-shipped anyway...) -- Alan Denney # Informix # aland@informix.com # {pyramid|uunet}!infmx!aland "Out on the highway doing 98... radio's blastin', and he's tempting fate He swears he saw an angel in a black Corvette She was blowing him kisses through her cigarette [Was (Not Was)] Boy's gone crazy; it's not just a phase, he's one step over the line..."
