Can't read all HD capacity

[Guest]

Hi! I have two HD 1 master with a capacity of 120GB partition into 3 c,d & e.
My problem is if I install a slave of 80Gb its reading okie but if I install
my 120 GB to put as my slave it just reading 32 GB. I tried installing this
120 GB to other computer and no problem reading the total capacity of 120GB.
What else could be wrong? its beyond my knowledge.,..any help?
pleassseeeee,,,, I configure my bios to read in auto for master and slave.

You have a different OS on the 'new' primary drive?
It is running XP SP1 or SP2?
If not, it won't recognize a drive bigger than 132GB or such.
Did you check Disk Management to see how the drive is shown?
