I have been trying to install an IBM 25GB HD on my PC for the last few days and have had no success.

I have finally worked out that my PC does not support Ultra DMA so I will never be able to connect it!

My chip set is 440FX, I don;t know who manufactures the motherboard, I'll post it later.

Do I need a new PC, or is there any way around this problem, possibly an Ultra ATA adapter?

Alll I did was go to the IBM website and down loaded a funky little program that set up, partitioned and formatted my drive (you will need the serial number of the drive).

Online manuals for your drive are at

I am talking about Disk Manager (version 9.47). You make a bootable floppy and it does the rest. If I right (please don't have a moan if I am not), it runs at bootup before loading your O/S.

Worth a try it is free and it didn't take long to download.

Dave,

Does your chipset support DMA?

Although my BIOS says that a second device is installed, it doesn't actually recognise what the drive is?

According to the help text on the diskette, my chipset is not supported.

If I used an Ultra ATA/66 controller, which has it's own BIOS, will this oversome the problem?

I think I'm getting out of my depth here!

Does anybody know a decent PC builder near Milton Keynes?

It's probably nothing to do with UDMA, because the drive will fall back to standard mode-4 DMA. It's more likely that your BIOS doesn't recognise very large drives. A BIOS firmware upgrade may be available, although not knowing the MB manufacturer is a slight problem!

A separate controller should also solve it.

I've ordered an Ultra ATA/66 controller from Promise. i spoke to a pre-sales guy there and he assures me that it will work.

Thanks for your replies.
