Most modern disk encryption mechanisms have settled on XTS (with AES). That includes dm-crypt, FileVault2, BitLocker... XTS is effectively a way to build a really wide block cipher: typically 512 (== 1 classic sector) to 4096 bits (== 1 modern sector) instead of the usual 128 bits (for AES). (Yes, yes. Technically a tweakable block cipher, four points for Gryffindor &c.) With these systems, file system corruption is not a significantly different issue than it is with other systems. It is not the case that a filesystem is much more likely to become entirely or largely inaccessible than it would be if it had not been encrypted, unless if course if you lose the key! I'd be in remiss if I didn't mention that while XTS is the standard, it fixes a very specific kind of problem, and you probably still want something on top with a more traditional form of encryption for specific sensitive files. To be clear, the advise is not "don't use FileVault 2"! It's: "do not only use FV2". My work machine, for example, is FV2, but all important credentials are GPG'd using a smart card that's normally not attached to the machine.
