Bad clusters and FDE

OK, i've discussed TrueCrypt with you guys before.
I know that Truecrypt (thank god) refuses to encrypt a systemtem partition for a whole disk encryption-solution, when encountering a bad cluster apon encryption-proces.

But where do the other and commercial FDE-products stand on this?
Does DriveCrypt and Pointsec refuse to encrypt a drive with a bad cluster?

I can ofcourse aks the vendors in my own country, but:
A: I think their knowledgde doesn't go that deep to give me an accurate answer
B: there commercial, they'll probably want to sell me their FDE-producy regardless if it will work on my (perhaps) older drive with a few bad clusters.

What do you guys think how other (in relation to Truecrypt) software would react to bad clusters upon encrypting a disk?

 

Well, we really don't know what those other products are doing as they are closed-source. If they make no specific claims, then it's trial and error. The beauty of Truecrypt is it's open-source code. Honestly, I wouldn't mess with any other product.
