Aurin I've got the HDD working. I still cant write to the SSD though
That changes things a bit. Originally it was the HDD that wasn't accessible. I was hoping that the HDD wouldn't turn up in GPartEd, and the cause might be a simple hardware issue that's easy to resolve, like a bad SATA cable.
Nothing comes quickly to mind regarding an SSD that does show up but can't be written to. No spare room on the SSD would be one possible cause, but it would be obvious if that were the case. SSDs don't last forever, some more than others. It's possible it's just a faulty SSD.
Just how did you get your HDD working? It may not be related to the SSD issue, but I'm curious. Maybe others here will come up with ideas that might help.
