Question SSD-HDD combo error 1720- smart hard drive detects imminent failure

Oct 23, 2019
I am using HP desktop i7-3770 and 256gb SSD windows10 pro 64bit (build 18362 updated to 1903). System model is HP Compaq elite 8300 SFF.
I have an old 3.5" 500GB HDD. I want to use it as an extra storage disk. I connected it to motherboard via sata cable.

When I turn on the PC, I got this warning.

1720- smart hard drive detects imminent failure
Failing drive: sata4 (Black)
failing attribute: # 05
To minimize the risk of data loss, backup the contents of your hard drive and run DPS Self-test in F10 setup.

At the bottom was written F1 boot. So I pressed F1 and PC turned on as always with no problem.
From management I format the old disk. I restarted PC again it gave me the same error. I pressed F10 and access the bios and I run DPS self test for the old disk. It says "Test failed. Drive replacement recommended"

Is there any way yo use it.Or I just can't use that old disk while I am using windows10. Because I was using it before while I was using windows7.

Thank you in advance

Hi @taus35 ,

Unfortunately, that old HDD has reached it's EOL & needs to be replaced.

Sorry for the bad news. But hey! A 500GB SSD can be had for around $52, even cheaper if you buy it on sale. I bought this exact one while on sale for under $30 2 years ago (Or any other brand within your budget) and as you know, an SSD is faster than an old (or even new for that matter! lol) HDD.

Attribute #05 is the Reallocated Sector Count. The drive has too many bad sectors, probably more than 500.
I have another PC which has the same configuration. I have another 1TB HDD and it is working properly with that PC. Now I will try my 500GB HDD with that PC. If it is not working as you said it has too many bad sectors.

By the way, I was using that 500GB HDD before without any problem.

Thanks for your response.
