WHD20-W4X error detected on hard drive scan

Hi,

Dell techies.....

I bought a dell inspiron 3420 a few years ago.

Recently I installed system assist software and ran a hard drive scan.

My hard drive is ST500 LM012HN-M500MBB.

The error code was WHD20-W4X.

The laptop hangs sometimes.

Can I fix this error without replacement of HDD?

Is there any software fixes for this?

I hope u will give me right answer.
