I have a hp pavilion laptop which has both as ssd and a secondary HDD that acts as my d-drive.
When I was using my pc the drive vanished.
The drive didn’t appear at all through disk management either.
However it’s back today and disk management says it’s healthy and all the data is on there?
The night before I was recording a vid and my file explorer crashed by editing a video on the D drive. I don’t know if it was a warning sign.
Please check the SMART values of the HDD and make a backup of your improtant files while they are still readable.
It could be a loose connection. Maybe try a different SATA data cable, different SATA port on your motherboard and different SATA power cable.
Cheers for that. Will try that when I get home. Going to get an Idrive too so I can store all the important stuff online.
