what does this report mean drivedx

Your hard drive is starting to fail. Three sectors have already been reallocated which is usually a sign that more sectors will be going bad. Plus at the end of the report there are five errors listed. Four of those errors are "Uncorrectable" errors ("UNC") plus one "Unknown" error. These are not good signs and may involve data loss or corruption.

If you feel this laptop is still worth putting money into it, then you should replace the hard drive with an SSD which will give the laptop a bit of a performance boost.

You should always have frequent and regular backups of your computer and all external media which contains important & unique data.

While I've used DriveDx on Late 2012 Mac mini i7 quad-core server 2.3GHz (2- HDD,

three installed macOS, four partitions equal capacity 500GB; & 16GB RAM installed) it

was a good tool; showed great potential. It also suggested my main HDD had failed.

Were you able to find & read a user-guide a

ASC contributor wrote, to help use DriveDx?

iHad a few drive failure notices; so had to go looking for suspect troublemakers, &

gave few the boot. (Two original 5400-RPM 1-TB HDDs. Replacements may be due.)

One of the cures for otherwise OK rotational hard disk drives, that may or not help:

To backup everything you want to keep to external drive; & separate Time Machine..

And then erase/reformat/overwrite zeros with Disk Utility; then re-install parts you

want to be there. And plan on getting new replacement or upgrade faster RPM HDD

or a larger faster SSD. ~ Be sure if any firmware is needed, that gets installed before

SSD + OS upgrade (if Mac has anything newer to consider; or worth the trouble, etc.)

Between EtreCheck and DriveDx, I was able to remove some bad actors; and without

erasing HDD, installed all new macOS on a partition; it has seen stable improvement.

As I'm more novice with things like DriveDx, have used many other utilities to fix stuff.

And I didn't understand some of your saved 'reports' ~ except to suggest drive failures.

[Undoubtedly a better DriveDx interpreter, could look through, and offer real advice.]
