OSX on 160GB SSD, Win 7 installed on Boot Camp partition from the SSD

[MythicFrost]

Hey, I'm about to install Windows 7 into Boot Camp on my Intel X25-M G2 160GB SSD, so I have about 30GB for Windows 7.
Is it possible Windows 7 can erase data on my partition with OSX on it, say for example if Windows 7 supports TRIM and OSX doesn't could that cause a problem?

Whether TRIM is supported on the SSD yet I don't know, but either now or later could it be a problem?

It's always best to have a backup before doing this sort of thing. That said, Windows 7 shouldn't mess with your install unless you select the wrong partition or tell it to format your "unreadable" OS X partition.
