Your hard drive is made by a company...most of those companies provide a diagnostic utility which can be used by any user to asssess the condition of the hard drive.
There is no generic utility that I know of which works on all hard drives...so users must look at the specs for the hard drive to see who the manufacturer is (Start/Run...type devmgmt.msc and hit Enter...then click on Disk Drives to see the model number), then go to the website of the hard drive manufacturer and download the appropriate utility.
The utility in .iso format is the one wanted, if different formats are offered. (If .iso file is not offered, download utility and put on floppy.)
This is normally then burned to CD...result is a bootable CD which contains the diagnostic.

<<If I run wise registry cleaner, there are a ton of errors I think 44 of which cannot be fixed and even if I run it, a few hours later a second scan will reveal new registry errors>>
If the hard drive is good...then I suspect that your use of such...has damaged your O/S and you need to either clean install, repair install...or run the sfc /scannow command.
