45gb hard drive recognised only as 32gb. Why?

hi all,

i have an IBM hard drive (75GXP 45gb) which i bought from simply earlier this year after Bob informed everyone of the special deal. i used it initially on an abit motherboard using a promise fasttreak UDMA 100 controller. everything worked perfectly.

this week i built a new system using an ASUS CUSL2-C motherboard i bought from pc world. i installed the drive on the UDMA 100 eide primary port. my drive was configured as two partitions. as i installed the drive i fdisked the primary partition. on installing windows it was reported that parts of my logical drive were corrupted. it went to scan disk. but at the rate it was going it would have taken all week. so i cancelled it and fdisked the whole drive again. now the drive is only being recognised as 32gb. i decided to try my promise fasttrack card. even it reported it as 32gb. whats happened?

my guess is that the motherboards bios may not support drives bigger than 33gb. but then the promise card has its own drivers and should have recognsed it properly and this motherboard is newer than the abit board.

has any one come across this problem or have any advice?

much appreciated.

thanks.

It WILL be the bios........I just done this recently and had to update the bios on mt chaintech MB to overcome this very problem.

It may also help to use IBM`s disk manager available free on their site which overcomes some other problem of the drive not reporting itself properly even when the bios DOES allow >30gig drives.

There is also a "drive fitness" utility on the IBM site.

Go do it now!!!!

good luck!

It's quite possible that you changed a jumper on the back of the IBM drive accidentally - the one that cuts back the size that the drives reports itself as being - to 32GByte.

Check this before doing anything else.

hi bob,

you might be on to something there. As a matter of fact i did change the jumpers but i'm sure i put them back how i found it. i had originally changed the jumpers so that it would act as a slave drive but that did not work so i changed them back. Bob as you have ( or had ) the same drive please comment on the following.

at the moment the 2 jumpers are on (looking at the back of the drive) the top and bottem of the far left pins (vertical) and the last two pins on the right on the bottem row (horizontal). this is supposed to be Master. Am i correct Bob?

http://www.storage.ibm.com/hdd/support/dtla/dtlajum.htm has a data sheet for the jumpers on this drive

tbl,

As you'll see if you look at the url sepulcre has provided, my diagnosis was right - you have accidentally put on the 32GB limit.

You need to move the jumper that's horizontal. It should be upright on right over the last two pins - again as the url shows (first jumper-setting image on left of page).

(sepulcre - nice one!)

Cheers

It’s amazing what typing '75GXP' into goggle’s search engine gets you!!!

I’ve yet to find a query that google can't point you in the direction of if not completely sort for you in seconds.

You can tell I get bored at work.... Can’t you!!

I'll second that. Found google to be just about the best "search" engine around. I tracked down a person in the US I needed to trace. Tried white pages, yellow pages, email searches, bigfoot searches, all the b****y searches I could think of. Finally tapped the name and the city into Google. It tracked the person down just because an enquiry had been made on a bulletin board about trans ams. An aol email address was there for replies (which was not generally available) so I was able to make contact. Off subject I know Bob, but must support sepulcre in his aclaim of Google.
