This a very essential thing to be aware of if you have a hard disk full of memories and mixes chucked away somewhere. Take it out, refresh the data, add checksums to it, and take redundant backups. Repeat the process by comparing checksums once in a while. :) As someone who lost data (not data rot though), I know the pain!
To verify checksums, on Windows, there is a handy program called certUtil that you can use from the command line. With the -hashfile parameter you can use MD5 or SHA256 to get the hash. Use it like certUtil -hashfile path/myarchive.zip md5.

md5sum path/myarchive.zip.Reply
