Volume /dev/rdisk1s1 found to be corrupt and needs to be repaired

Hi

My mac pro 13 inch 2020 has been going berserk.

Not sure what happened or what it means.

I ran first aid and got this. Do I need to take my computer to get repaired or can I repair myself in Disk Utility or something else?

Looking forward for my questions to be answered.

Thank you.

your Mac is not damaged in a way that the service department can help you.


the Directory of any drive is like collection of scoreboards that keeps track of File Attributes and extents (where the data blocks are placed on the drive). Each is generally organized as a set of trees (like linked lists) of things.


Disk Utiity ONLY examines and attempts to repair DIRECTORIES -- it does not read any Files at all.


The report says you have a snapshot that is damaged, and continues to say it will not be repaired (if time machine needs it better it will reconstruct it later.) That is all very unexciting.


Then it begins to examine fsroot -- the File System Root. This is VERY important, and MUST be correct.

it finds many problems, but claims it has tried to repair them. The overall repair passed.


if you are still queasy, run Disk Utility again, and see if the number of errors has gone down.


¿What exactly is stored on rdisk?
