Does taking out a Ps3 hard drive void the warranty?

May be...

my friend has the 60gb model and i have the 40gb model and his can play ps2 games. I want to swap mine and his but he wants to keep his HD.

No. Sony made the PS3 so you would be able to change the harddrive whenever you wanted. your warranty is still valid.







"



The PLAYSTATION®3 computer entertainment system hard disk drive (HDD) is removable and upgradeable. An upgrade can be performed by removing the hard drive and replacing it with a larger capacity drive. Please refer to the PLAYSTATION 3 system owner's manual on how to properly upgrade the hard disk drive. The HDD must be a 2.5” SATA HDD.



Sony Computer Entertainment America, Inc. (SCEA) does not have any information regarding specific compatibility or recommendations for hard disk drives for the PLAYSTATION 3 system. Upgrading the HDD will not void the warranty, however, the consumer takes full responsibility when upgrading the HDD. If you wish to back up your data, you may use the back up utility on the PLAYSTATION 3."

Not sure about the question, but by the way, swapping hard disks isn't going to allow you to play PS2 games: the hardware in the 40gb model isn't the same as the 60gb (60gb has special semiconductors for PS2 emulation), so it's impossible in the 40 to do this.
