I have a first generation R6 that stopped mounting without warning. After talking with various reps I was told it's because of the firmware in the unit and that it's no longer supported so Promise can't help me. I'm desperate to get my files back. I understand I can get a Pegasus2 and put the old drives in there, but before I do that, is there anything else that can be done that won't cost me thousands of dollars?

Hi Jonas,
What is the light status of the unit and drives?
What is the last change made on the unit?
Are you able to access Promise Utility?
Thank you,

Hi Jonas,
Can you confirm if the Pegasus is visible in the MAC system report ?
You can also attach the MAC system report by using the below steps
Apple Icon > About this Mac > System Report > Choose 'File' & 'Save'.
If you have registered your product with promise, you can also visit https://support,promise.com and open a case with the logs for our review.

Hi all - I was wondering what the solution to this was. After trouble shooting it turns out it is my Pegasus R (which has been super trusty for the past 4 years) is now not mounting. I followed the insructions on how to check the Thunderbolt port and sure enough it is showing up deep in the Apple menus, just not on desktop/disk utility like it usually does. I too have about 8TB 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?
See image for System Report showing it is connecting way somewhere somehow.

Hi I found this....
Recovering a RAID Drive that won't mount: FIXED!
I was running a 2 x 2TB, RAID 1 on a FW800 enclosure, with over 600GB free. The array was listed as degraded in Disk Utility. I tried to rebuild the set, thinking it was just a logic error. When I saw the rebuild time was well over 3 days, I broke the mirror, thinking I would be able (as the message box indicated) use each drive separately.
As it turns out, the enclosure died, and after I broke the mirror, neither volume would mount. No matter what I tried I couldn't get it to mount. The volume was greyed-out in the Disk Utility GUI, and Drive Genius wouldn't touch it.
I searched for weeks, and finally found the answer here: http://dice.neko-san.net/2010/07/repairing-appleraid/
In short, I ran 'diskutil list' from terminal and located a partition labeled "Apple_RAID_Offline".
In my case it was '/dev/disk1' with an identifier of 'disk1s2' and an index of '2' and contents as 'GPT part - 52414944-5F4F-11AA-AA11-00306543ECAC'. The GUID-looking number in the contents refers to the type of partition, in my case "Apple_RAID_Offline" (source: http://developer.apple.com/library/mac/#technotes/tn2166/_index.html)
Then I ran 'gpt show disk1' to list the partition data for '/dev/disk1'. This gave me the start and size. I copied the output to textedit then ran removed the partition manually with this:
'gpt remove -1 2 disk1'
This removed the partition data, not the volume contents.
Then I re-added the partition with the type "Apple_HFS" with a GUID of "48465300-0000-11AA-AA11-00306543ECAC".
The command looks like this:
'gpt add -b *start* -s *size* -t 48465300-0000-11AA-AA11-00306543ECAC disk1'
You'll want to replace *start* and *size* with the output from 'gpt show disk1'.
The instant I did this, I could mount my drives!!
My data is like this...
sh-3.2# gpt show disk4
start size index contents
0 1 PMBR
1 1 Pri GPT header
2 32 Pri GPT table
34 6
40 409600 1 GPT part - C12A7328-F81F-11D2-BA4B-00A0C93EC93B
409640 62507136944 2 GPT part - 48465300-0000-11AA-AA11-00306543ECAC
62507546584 262151
62507808735 32 Sec GPT table
62507808767 1 Sec GPT header
what do i need here?
'gpt remove -1 2 disk4'
and
'gpt add -b *start* -s *size* -t 48465300-0000-11AA-AA11-00306543ECAC disk4'
anyone?

Hanif, what is a "FW800 enclosure", and why are you seeking help with it on a Promise Pegasus forum?

I'm facing the same problem with my Pegasus R6, my MAC can't read and show the message uninitialized.
There are many data in my RAID drive and want it back seriously. Pls let me know how can I get it back and what is the step to do. Thanks.

I'd love to follow this up - did anyone have any success here? I'm cautious about hitting up Terminal, having a bash and potentially doing more damage without some guidance from the Promise team first. Would love to know if there's a list of things we can check through to get our data initialised so when can migrate off their legacy systems.

I am having the same problem. All ligths are normal on my R6. I'm running Blackmagic Designs Intensity Extreme through the Thunderbolt connections. I've tried it with and without. Nothing is working. I have tried the Promise Utility and the app opens but nothing is available. No interface. Menu options all greyed out. Attached are images and troubleshooting options described above. I need serious help with this issue.
Thanks in advance for help and support.

Almost same problem with my Pegasus R6 unit. The device is not mounting, however the Promise utility can access the device and report everything is operational (green check marks). Anybody solved the Pegasus units not mounting problem... Disk util can see the device, but it is not coming up as a volume. Any help is welcome.
