Quantum Fireball CR 13Gb drive

I've just bought a shiny new Quantum Fireball CR 13Gb Ultra ATA 66 hard disk and successfully installed it on my unidentified Far East clone motherboard.

Problem is ... the BIOS sees the drive as 13Gb, and reports it as such on boot up, but FDISK and other utilities including Partition Magic only report it as 8Gb.

I'm running Windows 95 OSR2, the drive is installed as the primary on IDE channel 2. Moving it around gives identical results in all the IDE channel combinations.

If the BIOS reported it as 8Gb I'd think it was a BIOS problem, but that's not the case.

Any ideas anyone please?

Phil.

I guess you have Partition Magic 3, which can't do anything with drives bigger than 8.4GB.

As for Fdisk - run it in dos session from within Windows, I'd be surprised if it didn't see the entire drive (if you press Y, when asked as it starts). Then restart the PC and format the disk from within Windows.

Sadly Partition Magic 4.01 didn't see more than 8Gb either. FDISK didn't recognise more than 8Gb for the drive even when run from within Windows 95.

I downloaded a utility from Quantum's website - a cut down version of Ontrack's Disk Manager - and as
suggested disabled the drive in BIOS. This special driver then finds the drive on startup and makes the full
13Gb available to FDISK.

Sadly the benchmarks for the drive show 3.09Mb/s without the driver (8Gb size only) and 1.51Mb/s with the driver
(full 13Gb), so I can at the moment have either a fast(ish) 8Gb drive or a slow 13Gb one.

Any more ideas anyone please?

I have the same drive running in NT, using the disk benchmark software supplied on this site I get 18Mb/sec sustained throughput with a 250Mb file. On smaller files I get 7-8Mb/sec. Are you sure it is running UDMA within the operating system / BIOS ?
