I've got a new Maxtor Fireball 3 hard drive that was a warranty replacement. I want to use it to store backup images and data. Therefore I want to be able to access it from dos in the event of an OS failure. The problem is that this hard drive just does not exist as far as Dos is concerned. Even if it is the only drive in the computer jumpered as master or CS. The odd thing is that Windows XP has no issues with the drive and reports it as a healthy FAT32 partition. The drive is reported on the bios generated startup screen as the correct drive, whether master slave or whatever. I've tried WindowsXP, Me, and 98SE generated system diskettes to no avail. If I run fdisk, the error reported is "can't access drive 1." If I try to switch to the drive letter, say c: if it is the only drive in the box, the error is "invalid drive specification."

After much trial and error, I put the drive in another computer and booted to DOS using the same boot disk I had just used on the suspect system. Also Athlon cpu, but different motherboard. Bingo, there was the drive, as expected.

So I guess I have a motherboard - drive incompatibility, or bios problem? The motherboard in question is an ECS k7vta3.

Maxtor support was no help. They washed their hands of the problem once they established it was working correctly in Windows XP.

Any ideas?

Esteban

Sorry. Because it is only Dos that won't recognize the drive I thought this would be the appropriate forum.

Shall I repost it in the hardware forum?

Download and use the Maxblast bootable diagnostic diskette for your Maxtor hard drive.Run the tests and follow on screen recommended corrective measures if any.Some VIA chipsets like possibly ECS k7vta3
cause problems with Maxtor drives and diagnostic software:see their website for these concerns.You can test the drive in a non VIA based computer.Timing may be a problem:if this is not the boot drive on first port use it as Slave rather than Master if you can on the second IDE port or the other way around.Make sure you have a 40 pins,80 conductors IDE cable.Good luck.

If the drive is formatted FAT32 then no FAT16 boot disk will read the drive. I'm assuming that is drive is probsbly larger than 60 GB.

EstebanUno,

What's the size of your HD, and how many partitions are inside?
