Missing Hard Drive

By robt-nelson ·
I am putting together or should say reconfiguring a PC for charity and am
having a problem with it getting to recognize a 2nd hard drive under Windows-95.
System is a generic 486DX100 with 16 MB Ram, has 2 hard drives, (1st one is 1.6GB, 2nd one is 850MB), 4X CD-ROM, etc.
It WAS running DOS/Windows3.1 with no problems!
Drives were configured as : #1-HD=C: & D:, #2-HD=E: & F:, CD-ROM=G:

After FDISKing and Formatting the hard drives (#1 as C: & D:, #2 as E:),
using Windows-95 Fdisk & Format.
I loaded Windows-95/SR2 with no problems, except that Windows does not recognize or report that the 2nd hard drive exists and both MY COMPUTER and Windows Explorer just hang when executed. Also, starting in native DOS mode and trying to do achkdsk or scandisk on drive E: also just hangs the system.
If I turn off the 2nd hard drive in the BIOS, Win. Explorer & MY COmputer work fine and report just C: & D:.

Thsi is driving me crazy!!! Please help!!!!


Thank you VERY much!!!Sincerely,

Rob

Hi Rob,
check the master/slave settings of the HDs. Maybe try to connect them each as the master on the first and second ide connector. Sometimes the CD has to be connected to the first ide connector (as slave); I don't know why. Is the bios capable of accessing HDs larger than 512MB? Maybe you have to use somewhat like the ez-drive utility. If this doesn't help mail me more data: dirve type, jumper settings, board and bios info, how you connected the cables...

As stated in original question - Windows-3.1 recognized both HD's fine, therefore BIOS did NOT need upgrading, and jumpers were set correctly also since both drives worked fine in DOS-6.22 & WIN-3.1!
Only difference was that in WIN95, 2nd HD was FDISK'd and formatted as a SINGLE drive (E:) instead of 2 drives (E: & F:) as they were under WIN-3.1.

Problem turned out to be AUTO DETECT for HD's in BIOS was set on. Turned it off and typed in HD params and WIN found 2nd HD okay!
Thanks for ur suggestions anyway!

First update the bios.
Take the jumper off the hd you want to designate as slave and system will auto detect the slave,make sure they are not hidden partitions,and the drives are not compressed.If you have access to partition magic use it to createthe partitions.

I had a similar problem with a Gateway that I am currently working on. C: is a 2 gig hd and d: is a 10.2 hd. It is a 120P. When I reformated for Win95, it would not see the second hd but recongized at startup. I updated the bios but they still did support that size of drive. I had to use Ez-Bios that comes with Western digital hds. That part works great right now anyway.

1. Check your jummper settings.
2. Update your Bios, and try it then.
3. Check to see if you have something like Ez-bios.

I hope you get to work.

1>Are the drives showing up in bios setting and are the setting right? If not check master/slave jumpers and then make sure that pin 1 (red side of cable is on pin1)
Upgrade Bios
Make a boot disk.

Try booting up in DOS and then try to access the drive. If you can't access it. Try swaping the hard drive. Make the other one master. You might want to try reformatting the drive. If that does not work You might have a bad hard drive

Try 1)conect to first HD as master ; make sure that the jumpers are set korect!
2)reboot the comp..go in bios and select "IDE detect" ..u should "see" the 1th HD..by now
3)u have 2 posibilities to connect the 2nd HD .. "As SecondaryMaster" or "As Primary Slave"
4)..but! if u want to have in the same time the CD i advise u to connect it as "Primary Slave" ;the cd jumpers are set ..by default in "Secondary master Position"
5)in this case u need to have a ..second connector ..and the jumpers set for "Master" too.
6) reboot ..press "Delete" to go in BiOs ..repeat the 2nd step ..u r done!
