Hi Chushi, thanks for your offer to help.
I do have other SATA devices. I use a HDD to store my Steam games but I haven’t had any issues with it. When my computer fails to boot, I can go into my BIOS and see the HDD there but no SSD. Also the fact that I have seen the same disconnects on a new SATA3 PCI card would appear to rule out the computer side of things.
It appears to me that the fault is at the SSD connector. As I mentioned above, just tapping the connector of the SSD is enough to allow the drive to be recognised again.
I really wish this wasn’t the case as I now have to look at reinstalling my OS ???
