Reason I was asking is because I wanted to know if they had been formated yet.
Which they have, and for some reason the file systems on those partitions is either corrupt or encrypted.
Do you remember any changes or anything that happened before they stopped working?
And reason why I ask about why so many partitions is they are all still on the same drive, the drive dies they all go with it. So normally I keep everything in one partition as there is no speed benefits to have the extra partitions (They all share the same hardware so writing from one to another is just the drive working twice as much), and if you start running out of space you dont have to resize. At the same time people also like to keep things organized so totally valid reason to have them :-D
Right now we need to focus on getting those readable again to get your data back at least. But we have to find out what happened first
