The slower path is to still boot from another drive and just repair the drive. If you have issues with a wiped / empty drive - you can seek hardware service knowing that your data is backed up. When you are booted from an external USB, repair the drive twice to see if the second pass is faster than the first. I would get all the files backed up before you try to run the repair since a slow check almost always happens when storage is failing (but doesn't always correlate and certainly doesn't cause the failure itself).ДЄt this point once you're backed up, you can take the fast path or the slower one:ДЇast path - download the OS installer you want (High Sierra or whatever) and wipe the drive.

On the other hand, an hour to check one snapshot and you're back in 'this is taking longer than usual by dozens of times'.

If your fsck is taking 2 minutes to run, but you have 30 snapshots - there goes an hour on a full fsck and no 'problem' other than perception. If you're on APFS - you'll need to look at the logs or enter to the command line to determine how many snapshots of the volumes exist. Depending on how many snapshots you have, this might be normal but you'll need to get some details to know.

On HFS+, something is wrong for a less than TB sized Apple SSD to take 30 minutes to run a check.
