hmm yeah ... what gxman & guthmund said.

and i feel the same way as guthmund feels. no 3rd party stuff.

i'll assume you have the proper ide cables (that lets you connect 2 ide/e-ide devices). you have 2 e-ide ports on your motherboard. each port can support 2 ide/e-ide devices : master & slave (harddisks & cdroms usually). ergo, 4 ide/e-ide devices.

since you have 3 drives + 1 cdrom. you're just nice. provided you have the 2 ide cables that lets you connect master & slave. if this is the case, you do not need to take out your cdrom, just connect up your 3rd hard disk.

if not, you'll need to follow my previous reply. but know that you can have 200gb of space ... what gxman and guthmund said. the cables should be easy to obtain and dirt cheap.

finally. if you do it my way or gxman's way. how would you transfer the data? Simply use windows explorer. it's just a matter of copying or moving your data to the new drive.

p.s., you do realise you have to partition & format your new drive don't you? XP isn't it? Goto Start->Settings->Administrative Tools->Computer Management ... Look at Disk Manager. You should be able to do it from there graphically. Careful not to mess with the 40Gbs.

again. good luck.
