I like the way the program is laded out.
The only problem is that the program tells me it will take hours to do a drive check for a single drive and it can't be canceled...which blocks me from using my computer. The number of hours is not known.
What happens if the computer crashes during a drive check and its repairing sectors...do I loose access to my drive?

Beneficial or detrimental running this against a SSD drive ?

Maybe this program is useful to very naive users, because the interface is simple, but simple comes at a price. It was unable to detect the SMART data from either of my SSD drives (whereas every other disk testing software I've tried can read it fine), and it seems to only offer very basic testing, which is already available in Windows without this program.

I see that this program uses chkdsk from Windows when asked to analyze drives. It does not read S.M.A.R.T from my SSD as do other programs (HD Sentinel, ChristalDisk Info, etc.). So I don't get the Health Status based on available spare sectors on my SSD. To me, only good to plan automatic checks as I know my SSD is near its useful lifespan (only 4 years with no excessive use).

From the screenshots, it appears that this program only offers basic information and functionality.

If you're serious about proactively monitoring your HDD/SSD status, then Hard Disk Sentinel is the best choice. (Not free, but well worth the price.)

Never received an unlock email. As instructed, I sent an email to contact@abelssoft.com, but it was rejected.

its era of solid state drives not hard drives.... so this might not be usable.... if you have something like this for SSDs ,then i will go for that onee..
