Bad Block scan is available in Tos (5 and 6 at least)

Update: I finished testing one of the four 20TB drives, and it had no defects. The test took over 50 hours. I will be back to update how the testing on the other drives turns out.

@Gremlin Thanks. I uncovered where the test was in the UI (i.e., the Play button for selected hard drive) a little late. I decided to go with the longer, more thorough 50 hour test to be sure.

Hard Drive Tests Follow-Up
FYI, I tested all four of my Western Digital Red Pro 20TB WD201KFGX hard drives with Hard Disk Sentinel ("WRITE + read" tests), which resulted in no errors. It took about 50 hours per drive to run the test (a destructive write test and then a read test).
