No all shortcuts to the 2nd HDD have gone without trying to open them. All my documents and MS Office and some other programmes were on the 2nd drive.
No lose cables, lots of dust, but no joy.
Removed the HDD and used a USB3 caddy. Shows it as drive E: in Windows Explorer. Then it disappears.
When I access it just says "you need to format the disc in drive E before you can use it" "Windows Explorer has stopped working"..........
I have heard that data recovery is very very expensive!
The last message I got when trying to read E: .."Data Error (cyclic redundancy check)"
I will get it checked on another PC.
Thanks for the input.
