Any Windows user can see and read files on the Mac partition.

Personally I'm not sure how Windows is seeing the OS X partition. For any of the bootcamp partitions I have created/used the OS X partition is not visible to Windows.

When using XP how does your User folder, and thus all your personal files, display? Do you see the OS X partition as a Hard Drive or are the folders shown some other way?

a) I think the file is in > C:\Windows\System32\drivers\AppleMNT.sys < Just renaming it to "AppleMNT.sys.old" and restart your computer should take away the driver for reading HFS+ partitions.

b) Using FileVault on Mac would secure your home folder, but the rest of the HD is still readable

c) Hiding the partition in Windows by removing drive letter in disk management

I would prefer a) because b) and c) are just workarounds.

Wow - never knew this was possible. Is this something a user would have selected during the Bootcamp creation? Cannot remember ever seeing the option.

Also, is the file applemtm.sys? I could not locate applemnt.sys in my XP SP3 32bit partition.

Which Bootcamp driver do you installed? BootCamp 2.0 or 3.0?

I think the AppleMNT.sys is only for 3.0.

I used the version included with 10.6.7, which must have been 2.0 based on the outcome. Checking the Bootcamp FAQ for v3.0 I can see it mentions introducing support for viewing the Mac partition. Just now I ran the ASU in XP and the 3.2 Bootcamp update was installed, but I still don't have the mount sys file - I saw the file I noted before was actually for the trackpad.

Anyway, thank you for your reply. In searching I saw the OP had posted the same question in the Bootcamp forum and got a similar reply to your part A suggestion.

OMG. Really? Someone who has physical access to the computer has access to anything unencrypted on the hard drive.

Sorry if it appears petulent. If you give someone physical access to the computer, there is no way beyond encryption that you can prevent them from viewing the data. Shall I repeat that?

If you are not already aware, it is impossible to secure your data if you give physical access to the computer to someone else, short of encryption.
