Large HDD not recognised properly

  Anglia76 13:29 09 Apr 2004

Hello all, I would appreciate your help. I'm running an Asrock K7S8X motherboard with a Promise Ultra TX2 on Windows XP and recently added a 160GB Samsung hdd. The hdd is seen as 128GB by XP management. I have enabled big drive support fom Microsoft and updated the TX2 bios. The hdd is configured for large drive by tho onboard jumpers. I've "lost" 32GB, can anyone help? Thanks in anticipation.

hi anglia 76 ...
if you have formatted the drive ..then the count will be about right, as a percentage is taken up in the formatting.

I agree with Daxian. When you format the HD u never get the amount specified on the unit as a certain percentage is taken away the the formatting process. That is the reason why when u buy the HD it should say the amount "Unformatted".

32gb does seem a large amount to lose. I have 2x80gb drives and after formating they show as 76.74. A loss of 3.26gb each. j.

As Djohn states there is no way you would lose that much space through formatting. My suggestion would be to use Disk Management(type words into Help and Support Centre in XP menu) to partition your second drive and I suspect your missing space will be found.

No amount of formatting would use that amount, including using the Stealing way they use 1000Mb as 1Gb would not amount for it, there as got to be something else that's doing it

Start, Run, Type:


Click OK.

If this the second drive, the 160GB drive will be disk1. Do you see one big rectangle or two, three...etc, next to disk1?

Try something like Partition Magic 8, while find the missing capacity with ease. Well it did on my 200gb!

That's what I would do, but I use Acronis to do the same job

I have two Maxtor 160gb hdd's which show in windows as 152.66gb.
