Yes, I completely understand and agree that old habits die hard - but things NEED to change
There are BIG problems with fomat (the "slow format") apart from what you wrote (that you could not pause/resume):
1) Yes, what you wrote is true:
> and slow formatting would often block these sectors from being used
but format does it in the FILE SYSTEM level. It means that it does not actually force the hard disk to reallocate bad sectors (replace them with spare sectors) so it does not really fix the problems, but attempts to hide it.
This approach is wrong, because the solution is not permanent and causing more and more troubles and confusion:
- this decreases the amount of usable free space (as these bad sectors remain reserved)
- when you ever need to re-partition / re-format (consider a clean reinstallation) these sectors will be re-used AGAIN, risking data corruption/data loss
- if you ever attempt to clone/mirror the disk drive, the cloning may fail completely (due to bad sectors) or a cloning program may happily clone the bad sectors (!) so you'll see bad sectors reported by chkdsk on a brand new hard disk drive (even if the new hard disk is physically perfect, 100% health displayed in Hard Disk Sentinel).
2) the format is simply not sensitive enough: it does not show possible problems, health degradations, performance issues (slowness) and may not report possible retries. All of these SHOULD be detected and displayed - as this would help to determine (for example) if the disk drive is partially failing (for example there may be problems at the end of the disk surface).
Because of the above, personally I'd *never* use slow format as this is simply useless.
I'd much more recommend the testing (even on new hard disk) as displayed in Support -> Frequently Asked Questions page:
If you want to save time (as the above recommends the Reinitialize disk surface in addition to others) then I'd recommend to use ONLY the Disk menu -> Surface test -> Write test to perform a complete, single pass overwrite (instead of the slow format) or if you prefer to have a read-test, then the Disk menu -> Surface test -> Read test.
Disk Repair is best to be used on _already_ fomatted disks, where data stored, but now if I'm correct, we speak about new (or used) disks which should be formatted first.
So I'd use the Disk menu -> Surface test functions, as these solves all of the above mentioned problems: sensitive enough to detect/reveal problems and the write type tests designed to really FIX them.
The "Weak sectors" page ( https://www.hdsentinel.com/hard_disk_case_weak_sectors.php ) desribes the situation with logical / physical problems and how they reported by chkdsk (or generally by the format - which records bad sectors on file system level).
Then, when we confirmed the real physical disk status and verified the surface (and even stabilized if required) then a quick format is perfect way to make the disk drive initialised.
Personally I always do these:
1) Disk -> Short self test
2) Disk -> Extended self test
3) Disk -> Surface test -> Read test
4) Disk -> Surface test -> Reinitialize disk surface
and then a quick format - even on new hard disks - before using.
