Hi There - hope someone can help.
My Pegasus R6 will not mount on my Sierrra iMac
- it shows up in Apple Disc Utiliy but the volume listed as (-)
- it show up as if everything is fine in the Promise utility
- have checked that the cable is properly plugged in, restarted computer
What happened -
The unit showed a drive as having failed. I swtiched it off, restarted computer, and then it came back online. The mac showed an error message saying I could read from the drive, but not write, and that I should back everything up to another drive. This happened when migrating from a 2011 iMac to a new one. Unfortunatly the main film on the drive was a 2.5TB Final Cut Pro library, and the only spare drive I had was 2TB. The project would not open on the new iMac, saying it was already open on the old one (which was switched off). I plugged the R6 into the old machine, opened the project on the old machine and deleted the render files, and this got the library size down to less than 2TB. But when I moved the R6 back to the new machine the disc failed to mount.
This isn't the first time I've had a similar problem - the unit has had four discs fail over it's life, and it has done the "read but can't write, better back up" trick once before as well. It has not been very reliable. I've made it a habit to keep it switched off when not in use, and that seems to have helped. The two times it brought up the error message "read but can't write, etter back up" were when it was copying large files.
In the past I've been able to use the Promise utility to restore the drive, but in this case I'm more concerned about the data - that one big project - that I want to get back.
FWIW - I have a backup of the project on another disc, but the backup is corrupt.
Should I replace the drive that indicated it had failed (it was the bottom one, so easy to remember which one) and try restoring the disc with the promise utility - will that have a chance of getting my file back? Or just scramble things further?
