Red Alert: R75 Snapshots are broken

Just found out from 2 customers that R75 snapshots are broken..kinda. If you are upgrading from R75 to R75.20 and it fails (and it will), you can't just interrupt the boot and revert the snapshot. For some reason you have to rebuild the box as R75 with any hotfixes and THEN do a revert. UGH.
NOTE: When I was at CP support in Irving one advanced support person was trying to fix a huge bank that had corrupt backups/snapshots. They couldn't go forward or backwards.
NOTE: I took apart the snapshot .tgz and it had every file on the SPLAT disk. I really don't know why they can't restore the snapshot.....
Read my blog below on how verifying restores and pulling RAID drives.
