"Recovery HD" is now empty and unuseable, how can I repair this?
Quite some time ago, on a laptop that has hard drives internally mounted. I partitioned the drives.
To which, on one of the drives I created a "Recovery Disk" (disk1s3) specifically to be able to repair the hard drive that has the Mojave OS X 10.14 Operating system installed (disk1s2).
In the past I have used this partition named "Recovery HD" to perform diagnostics and to repair the permissions on said other partition that runs Mojave (disk1s2).
Recently I noticed upon staring up while pressing the Option key, that said "HD Recovery" drive was now EMPTY and I was no longer able to boot up from this partition.
Disk names from said drives using the Terminal Command "diskutil list" (key info redacted)
/dev/disk0 (internal, physical)
The first disk mentioned above here, has an older OS X , and is not where the challenge at hand is to be found.... So I have redacted this information.... continuing onward.....
/dev/disk1 (internal, physical):
disk1 - *240.1 GB
disk1s1 - EFI EFI = 209.7 MB
disk1s2 - Apple_HFS - (name redacted) = 239.2 GB (Which runs OS X Mojave 10.14)
disk1s3 - Apple_Boot Recovery HD = 650.0 MB
(^^ The CHALLENGE is with THIS partition^^
as to why I made this post.)
I guess my 2 part question to the Communities collective experience is :
1. How did this even happen? How did the "Recovery HD" drive, suddenly become empty?
2. How can I make this 650 MB partition a "Recovery HD" once again?
Specifically to be able to be able to diagnose and repair the aforementioned "disk1s2" that runs OS X Mojave 10.14 as I once had been able to.
Thanks in advance to those who reply.
