I am in the process of migration my R4 drive from a RAID 5  over to RAID 0. It's been going for 12 hours so far and has only done 5%. Can I shut down the computer (and will the drive keep working on this task) or do I need to leave the computer on until it's finished? At this rate it will be about 10 days.

HI Randy,

With the screenshot, I could see that there is free space on the unit. Could you please follow the below steps to download the complete subsystem report and go to and create a web support ticket for further assistance.


Follow the below step to save the subsystem report for further investigation.
- Open Promise Utility.
- Click subsystem information icon on the top of the window.
- Click the lock symbol on the left bottom corner of the screen to unlock the utility.
- Click on save service report button to save the subsystem report.   Regards Pradeep C

Thanks. The process has finished now but the capacity of the drive hasn't increased. If I go to OSX disc utility, it says it has but if I click on the info on the drive itself, it says it hasn't. Have a I missed a stage in increasing the capacity. I've done this before with an identical drive and didn't have any problems increasing the size but it was some time ago so I can't remember what I did.

Hi Randy,

Please do not shutdown the computer or Pegasus unit until the migration process is completed.

Thank you.
