I'd try googling that (if you haven't already), and see if any of the answers for other machines makes sense for your situation.
It's hard to give any specific advice since so much would depend on how exactly technogym set everything up, what hardware there is, etc.
You might be able to use blkid to find a filesystem (if there is one) and could then maybe try repairing with with fsck. Assuming it's a repairable filesystem error. I can't really help more, but that might offer a jumping off point :)
