As you already guessed, you should be safe with a 120gb drive. Chances are, you would be fine with a 160gb as well.
A system bios that does not support 48-bit LBA has a capacity barrier at 137gb. However, as long as the hard drive is recognized in some way by the laptop you should be able to utilize the full capacity of the drive when using an OS that has its own support for 48-bit LBA. Microsoft Windows XP w/ Service Pack 2 and Vista both have this support. Win 2K and earlier Windows XP versions require a patch/registry modification.

Lenovo seems to only offer upto 80GB upgrade drives. And I've heard people stating the 160GB won't be recognized. Logically, I think the largest capacity HDD I would be able to use in this laptop would then be the 120GB ones. Does anyone know for sure? Thanks. -rich
