[Cryptography] Disk encryption

[Dave Horsfall]

I've never used disk encryption before, so I have some concerns.

My understanding is that each encrypted block depends upon the previous 
block (if not the entire chain), so what happens should an intermediate 
block become corrupted?

I ask because I am now using an SSD drive (which I don't really trust), 
but I was brought up on spinning rust for decades (no encryption).

Thanks.
