Question about Dell OptiPlex GX280 PC Desktop

1 Answer

Cannot get 2 IDE devices to show in bios.

I have a dell optiplex, the primary HD is a Western Digital 160gb SataI also have a LG DVD/RW combo drive set to master on the IDE channel.

I recently attempted to add a 2nd ide maxtor HD and for the life of mecannot get both ide devices to show in the bios.. I've tried settingthe ide hd as both slave, master and cable select and the dvd drive the same to noavail, always one will show in bios but the other won't.. however bothide devices will show in windowsXP and work just fine.. being that Ineed my drives to be bootable I need them to show in the bios as well.

I've tried 2 different IDE cables now one being a brand new asus cable..

I'm curious as to whether it could be a power issue?

My power supply is 500W +3.3V +5V +12V -5V -12V +5VS8
28.0A 35A 25A 0.5A 0.8A 2.5A

I'm running currently:

1 Maxtor 7200rpm IDE

and most importantly, the energy hog PNY GEFORCE VERTA 9600GT

Other steps I've taken so far has been updating the bios, switching the cable and jumper settings to every possible combination, other then switching my Sata jumper settings which is OPT1 (I'm clueless on sata jumper settings).

The pc boots fine, although seems noticeably slower in boot and load times (although I had a virus or 2 recently that could be causing that) my main C: shows both in windows and bios, my dvd drive shows in both as well, my f: (ide hd) shows only in windows, even in disk management and works just fine.

Any advice would be highly appreciated as I've tried numerous forums, dell tech etc to no avail thus far. Cheers.

Does the computer have two IDE channels? If so set the Maxtor HDD as master on the primary channel and the DVD drive as master on the secondary channel. Also right click on My Computer, left click on Manage and left click on Disk Management and see if the drives show up there. Also check the boot order in BIOS.

HP Pavilion 7955 main HD failed; my data is on second drive (Maxtor ATA/EIDE) - still good. I want to install this as a second drive in Dell Optiplex 620 which has SATA main drive. The only IDE cables are...

Most IDE cables have THREE connectors:
* one to the motherboard
* one to the "primary" device (CD/DVD or disk-drive)
* one to the "secondary" device (disk-drive or CD/DVD)

If your IDE cable only has TWO connectors, buy a cable with THREE connectors, and connect your disk-drive to the third connector.

Dell optiplex will not recognize hard drive

Is it SATA or IDE? Have you tried another cable? If it's IDE, have you checked the jumper settings (usually Cable Select is easiest)?
