I updated my Mac Os to 15.4.1 and my (so far flawless) Pegasus 2 R4 is not mounting anymore,
I can see it on Disk Utility and it also shows on Promise Utility as ok.
I have reinstalled drivers, Reduced Security and All Kernel Extensions are Enabled.
Any ideas on how to proceed?
After trying differnt methods last night, now when I click on "mount" on Disk Utility, this is what I get.
I am the only user on this computer and also the admin.
Hi Lucas,
Updates to 15.4 or 15.4.1 are causing some few issues.
If you can see the volume in Disk Utility and you can see the Pegasus in the Promise Utility, then the driver is working.
This appears to be a filesystem issue.
The first thing to do would be to run First Aid. This will probably fail to repair the filesystem. If First Aid does not work, the macOS goto solution is a program called Disk Warrior. It has fixed the filesystem in similar cases. Be advised that Disk Warrior is not free.
Hi RP, thanks for your answer and help.
I ran disk utility first aid but yeah, it doesn't work. Only if I use it in the "parent drive" (pics follow). I'm waiting for the Redundancy Check on the Promise Utility to finish too.
About DiskWarrior: running it will fix the filesystem and I will be able to use it normally from then on?
Thanks again.

HI Lucas,

First Aid is a filesystem repair program. It failed to run on 'APOS FILMES' due to a permissions issue.
About DiskWarrior: running it will fix the filesystem and I will be able to use it normally from then on?
What is 'APOS FILMS'? Is it the name of the Pegasus Volume that normally mounts on the desktop? If it is then DIsk Warrior will probably be able to fix it.
Yes, APOS FILMS is my raid name.
So, DW should fix it and I would be able to use it regularly or is it a recover app like disk drill where I can back up and format?
Thanks again for your help.
