Have had our R4 up and running for 2 days. During those 2 days I loaded it up with files from other drives. During an upload from an external drive the R4 disconnected. Now it will not mount and I recieve an error saying "The disk you inserted was not readable by this computer." However, inside of the Promise Utility I can see the drives and see that nothing is out of the ordenary. I have tried new thunderbolt cables. Again, everything was working great this morning. All lights are blue on the box.  

**When I noticed the change today I had just plugged in our XDcam reader and downloaded it's software. I'm afraid that this may have taken over the volume.

I opened up OS Disk Utility. Pegasus shows up as an external. However, it is not capturing any information about the data. See Screen Shot. Options under DU is Frist Aid, Erase, and Info (infor screen shot in attachements).

Spoke with Chris at support. Went through our Pegasus and found that things were working on that side of things. 

Please help. 

Firmware version 5.04.0000.57

I am running on:

iMac 3.4GHz i7

16g of memory

OSX El Capitan 10.11.6

If you can contact it in Promise Utility and everything has green check marks, then try looking at it in OSX Disk Utility. You should be able to right click the Pegasus and mount the volume to OSX's file system.

Can you see the Promise Pegasus from Disk Utility? What happens if you right click the Pegasus in that app?

The Promise Utility says it is fine, but OSX says it's unreadable. OSX is what sees the files.

You can use First Aid in Disk Utility. For questions on that OSX app, contact Apple support.

Another app that customers come back to tell us about which helped them with filesystem issues is Disk Warrior. It's retail software from Alsoft, a third party. For more about Disk Warrior, please go here: http://www.alsoft.com/DiskWarrior/

We can also troubleshoot the Pegasus remotely to rule out any problems within the Pegasus causing this. Please call us at 408-228-1500 when in front of the Pegasus, or open a web support case under your registered serial number at http://support.promise.com.

I guess my question is...if the volume was blown away, but the drives are still visable via the promise utility...is there a way to see the data that was stored on those drives without using a data recovery software? There was about 10T on it.

Having the exact same issues as this. Ours has only been on for 48 hours?

Is there a straightforward solution to this, please?

Hi Justin,

 

It looks like this issue needs to be analyzed with the help of subsystem report to isolate the issue.You can call technical support at 408-228-1500 or reach out through support case at  https://support.promise.com/.

 

Thanks..

Hi Kunal,

I have sent the case to my next level of team they will check and get back.

I have about 14TB of footage/projects I can't afford to lose. How does one get Pegaus back on track or even to a point where you can transfer everthing you need?

Is there a straightforward solution to this, please?

Hi all,

I just had this issue after I finally upgraded to osx high sierra. when I opened disk utility I had 2 items on the left- "Promise Pegasus2 R4 Media" and "Promise RAID" The "Promise Pegasus2 R4 Media" was mounted. I tried to unmount but could not. However the "Promise RAID" was not mounted. All I did was mount it in the Disk Utility and everything was up and running. Hope that helps

The year is 2025 and I have this same problem. Replaced all 4 HDDs with Seagate 4TB Ironwolf Pro, setup as array, Raid5 and 1 logical drive, total 12TB usable. Synchronization took about 20 hours, then I started using it with no problem, editing 4k video, 650MB/s read and write approx. It operated fine from both an M1 Mac Studio and M2 Macbook Air. Then I shut down, moved the drive, reconnected and it no longer mounts, however the Promise Utility sees it fine and says there's no problem.

OSX Disk Utility shows an external drive called "Promise Pegasus2 R4 Media", but says it's "Uninitialized", so it cannot be read, or ejected, and disk first aid takes about 3 seconds and completes fine.

The drives were formatted as APFS. 

I've tried connecting on a Mac Studio M1 running Ventura 13.6.7, a Macbook Air M2 running Ventura 13.5 (both with all appropriate Promise drivers installed, and it worked on both for about 36 hours), plus an Intel based core i7 Imac.

I've generated a subsystem report, and happy to attach but can't see how to do that here. I don't want to lose the work I did today. Please help.

Cheers

Kristi

p.s. I just had the idea to put the original 2TB drives back in and see what happens, and they're no problem at all. They mount straight away in their 1 logical drive Raid5 configuration. Apart from the size limitation of the old drives, they're Toshiba from March 2014, hence why I was replacing as they're surely getting near the end-of-life.

Surely this isn't an issue of size or untested HDD? I've seen plenty of posts with people trying bigger capacity drives; and due to the Promise tested and recommended drives no longer being available, what other options are there?
