Help: TrueCrypt sharing volume btw Mac/PC
- Member Since
- Jul 23, 2010
I am using TrueCrypt in an external HDD (1Tb). I have created a volume to read and write files on PC. However, I can read but not write files on the Mac. I know that TrueCrypt volumes are fully cross-platform. Is there a way to mount a volume that I can use in both systems? Do I have to format the volume using FAT32? But can I use FAT32 in 1Tb HDD?
Can someone help me with this issue?
Many thanks for helping.

I am using TrueCrypt in the same, or similar, way (mine is a small encrypted TrueCrypt volume on my USB stick).
For the volume to be readable and writeable by both Windows and Mac OS X the volume needs to be formatted as FAT or FAT32. 1TB on FAT32 is fine - the maximum volume size is normally 2TB (but can be increased to 8TB using a larger cluster size). More details on FAT and its limitations can be found here.
As a slight aside - it is also possible to enable write support for NTFS write support through MacFUSE and the NTFS-3G driver. Although when I tried it, it 1) wasn't a straight single install, and 2) NTFS support was too slow to be of any practical use. This may have improved since.

Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).
