who needs hardware encryption these days
On a OSX Mac you can either run the cross-platform TrueCrypt OSS or just create (using Disk Utility) a disk sized .dmg with 128 or 256-bit AES encryption turned on. Works with any hard drive you care to mention and SD cards, CDs, DVDs and even over network shares (data is encrypted/decrypted at client end so it always encrypted across the network).
