hard drive undetectable

By gmax95 ·
I'm trying to install a hard drive w/ no luck so far. First of all, my pc is a P266 w/ Award BIOS 97-98. The hd is a Western Digital WDC-WD200EB 20GB IDE 100/ATA 5400rpm.

When I boot up, only the primary slave is detected, but not found. It then shows the CDrom. That's it. I've tried booting w/ a Win95 boot floppy and it does boot to the floppy, but only displays the cdrom. I've tried all the basic troubleshooting: ide cables, power supply, making sure the hd goes to ide1 and cd to ide2. Adjusting the jumper pins on both the hd and cdrom don't seem to make a difference. I've also opened up a similar pc and emulated all the hardware setting and connections to the motherboard, but to no avail.

I know bios after '98 will support hd 8.4GB and larger. This bios has a date of 3/18/98, but still has copyright of '97. Also, I've tried installing a known good 2GB hd and the same thing happens.

Any suggestions would be greatly appreciated.

Well, first you might see if you can download an updated flash bios for your system. I'm not sure that yours will support that 20gig drive. But, if it's not reading any drives, then try this...
I'm assuming your using the onboard controller on your motherboard. Try picking up an isa (or pci - depending on your board) controller card and see if you get any recognition. Also, have you tried disconnecting your cdrom drive and trying with only the hard drive? You mention that the "primary slave" is detected but not recognized. Are you running another drive as your primary master? The slave is the secondary drive so if you misunderstood that, you may have your answer. Feel free to clarify any of these things and I can see if I can helpyou further. Good luck!

If the CD-ROM is on IDE2 and you have changed the jumper settings on the HD and changed the IDE Cable, the problem is usually the IDE Controller on the motherboard.
Disable the First IDE channel in the BIOS and put an IDE card in a slot. Hook up the hard drive, and if the BIOS can see it, it probably is the onboard controller.
Flash the BIOS as a quick check, and if the BIOS flash does not fix the problem, the controller is the answer.
This is not so bad.
The UDMA-100 controller cards really speed up the boot of a 266MHz Pentium 2 , compared to the onboard IDE.

Hi - Sounds similar to what I was doing when I put 2 primary/slave 20gb in for my old 8mb.

I had some real probelms getting both disks, the cd, zip drive and a tr4 tape.

As I remember, when the Primary wouldn't detect, it was because I had put the cable on backwards or had both devices on the channel set to master or slave. With the Zip/Tape, I was never able to get the Zip to detect as a slave (well, OK, it's possible that in all my tries, I still got the cable or jumper wrong). TheZip worked fine as Secondary Master, Tape Secondary slave.

When I got it all worked out, it showed a 8.4 (Win NT 4.0 SP4). Using Drive Image / Partition Magic it showed 20gb. Various trial and error, DI 4 and PM 6 fixed that. I think I had initially formatted them with PM 4. In all this, detecting a drive > 8.4 when the bios/os didn't support wasn't an issue, it just saw the drive as 8.4 rather than real size.

If it doesn't detect, it's, cable, jumper, bios, bad disk, etc., no?

ATA 100 is a very fast transfer rate for this 5400 RPM Hard Drive. Your motherboard needs to be able to see and control at this speed. You will probably need an additional controller capable of ATA 100 if your MB doesn't specifically state that it can handle it. The controller is a chip and is separate from the BIOS. A P266 may not have one fast enough.
