The HD Sentinel, Crystal Disk , and HD Tune Health are all quick.
The tests that can take substantial time can be performed overnight.
Please make sure all drives are tested with HD Tune full error scan, Sea Tools for Windows long generic, and chdsk /r /v.
For the Windows drive make a backup image using Macrium and run chkdsk /b /v
For any drive that fails Sea Tools long generic replace the drive.
It's often best to replace drives that have bad blocks.
