Welcome to our forums.

Only one utility that I know of that claims to be able to do low level work on drives: Spinrite

Does Spinrite work with Macs? I may be a bit out of date with how things have developed, but I thought it was an MS-DOS programme? Maybe things have changed?

You can't run Spinrite directly from a Mac or I believe even from Windows. You need to be able to boot with FreeDOS and run it that way:

SpinRite
Computer program
SpinRite is a computer program for scanning magnetic data storage devices such as hard disks, recovering data from them and refreshing their surfaces. The first version was released in 1987 by Steve Gibson. Version 6.0, still current as of September 2018, was released in 2004. Wikipedia
Developed by: Steve Gibson
Written in: x86 assembly language
Size: 0.169 MB executable, 1.40 MB bootable disk image with FreeDOS OS
Stable release: 6.0 / June 7, 2004; 14 years ago
Preview release: none (none)
Operating system: Included FreeDOS (doesn't use OS of host PC) runnable from DOS


There are ways to run DOS from a Mac but it would be easier to boot from the included FreeDOS. I'm not sure how it would work but I do know back in the good old days, it was an effective program for repairing hard drives at the low level. Of course nowadays, that would not work with SSDs. :)
