Windows HDD in MBP?

[foulmouthedleon]

I have an external HDD which is a 320 gb SATA HDD. I want to replace my 120 gb HDD in my MBP but before I go buy a new HDD, wanted to see if my external HDD would work.

The catch is that the external HDD was my old HDD from my HP laptop. Could I simply reformat it for OS X or once it's gone Windows can it ever be used for anything else?

I suppose I could just remove my existing HDD and put this one in and see, but if it's a waste of time, I'd rather not.

Thoughts?

Provided it would fit physically, then yes it would work. You would need to change the partition type to GUID and reformat it to HFS+ but it would work

Ok, is that something that Leopard would take care of automatically (i.e. prompt me to do) or is that something I'd need to do before I put the HDD in the MBP?

Use the Mac's disk utility.

I hope it's a 2.5 inch HDD?

If it is, just install it, put the old 120GB HD in the external closure and clone the 120GB to the 250GB.
Remember to format the 250GB first, with GUID partition table as others stated.
