Mac hard disk drive failed SMART status. Problem: Mac hard drive S.M.A.R.T. (also known as Self-Monitoring, Analysis and Reporting Technology) is a monitoring system for internal disks and checks for issues. If the SMART check on your Mac hard disk drive reports errors or failures, it usually means the hard drive is about to permanently fail. Apple Mac Disk Repair – AppleJack. AppleJack is a troubleshooting utility for Mac OS X. It runs under Single-User Mode so it can be used even when OS X will not boot. AppleJack will repair disks, repair permissions, cleanup cache files, validate preference files, and remove swap files.

By the time the disk is tossing enough visible errors (that can't be overcome using the device's EDC recovery and whatever RAID might be in use), the disk has usually failed; has exceeded its ability to apply whatever replacement sector scheme and error recovery it might possess. I'd replace it.
If the disk was effectively dealing with its inherent errors on read, then you should not be seeing these errors. With the read, you should either get the data back from the disk, or you get the data back with the assistance of the EDC, or you get an error and you get the data from elsewhere within the RAID, or you get an error and presumed-bogus data if the EDC and RAID cannot recover the data.
And rather than the whole-disk overwrite, an attempt to write a bad sector with a typical disk should automatically cause the disk to re-vector the write over to a spare, meaning you shouldn't need to do the wholesale overwrite.

If you're using the overwrite as a disk hardware test, that's another discussion. I'd probably use a different tool, and specifically targeted to disk verification, but certainly setting known patterns and then verifying them is entirely feasible. Recovery tool software for mac.
To see what the disk thinks is going on with the errors, query the SMART data. There are a few canaries in SMART, particularly including scan errors, as well as the reallocation count, offline reallocation and probational count values. Those tend to point to an impending failure. The rest of SMART probably isn't as predictive, and SMART in general isn't all that good at predicting failures.
