I few days ago, I started seeing this message during boot:
NOTICE - HD SELF MONITORING SYSTEM has reported that a parameter has exceeded its normal operating range. Dell recommends that you backup your data regularly. A parameter out of range may or may not indicate a potential hard drive problem. Press F1 to continue, F2 to enter SETUP
When I hit
F1, it used to boot normally but then I noticed that my secondary hard drive is not visible in Windows Explorer. Now this message isn't appearing anymore when booting and BIOS cannot detect that hard drive either.
The hard drive never showed any signs of normal malfunction (sounds etc.) and never had any physical damage etc. It looks as new except some dust it accumulated over the years.
I switched SATA cables to see if they were corrupted but in vain. I put that hard drive in an enclosure but that didn't work either. The hard drive does spin when I turn on power on this enclosure. The computer boots fine without any issue but the secondary drive isn't visible at all.
Question: How can I retrieve data from the secondary drive which has these problems?
OS: Windows 7 Pro
Primary disk: 250GB SSD internal
Secondary disk: 2TB HDD internal
