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,

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

Thank you.

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.
