I’ve been having a few repairs coming in recently where an NTFS partition on an otherwise completely healthy hard drive has started presenting its self as RAW (with no file system). It’s not an easy fix but I can almost always recover the data from it for you! Let me know if you ever come across this before giving up on your data and re-formatting the partition. There’s a no fee promise if no data can be recovered too, of course. I’m not in the business of rubbing insult into injury.
I’m also partners with a data recovery specialist if a drive has a mechanical fault that requires a facility with a lab environment so there’s plenty of options available I can help you with.

Losing access to your files can be a frustrating moment and I’m sure some people reading this know all too well what that scary sinking feeling is like, so always be sure to keep backups!
