Anyone got any advice for me...

I have just fitted new Hard disk and i am trying to split into 3 partitions, this drive will be used on the secondary slave cable....when i partition it all goes ok but when i restart and goto windows or run fdisk again the last partition disapears....this happens if i split it to 2 or 3 partitions...if i make it 1 large drive it is ok as far as formatting goes...

But when i fit this drive slave to my DVD the drive is NOT recognised in BIOS or DOS so i cant format it like this... but it apears on the wrong drive letter in wondows...

if u need any more info just ask!

I am confused i thought it would be simple, all help appresiated, thanx in advance.
