Hi All My first posting here but I'm always trawling this great forum for answers. I'm in a bit if a pickle and hope someone can help. I have been unable to relocate my User folder to my external thunderbolt drive. I think the problem comes from OSX assigning a "1" prefix to the external drive. When I view the drive name in Disk Utility or Finder the Drive name is "Thunderbay" as I named it. Yet when I'm attempting to relocate my User's Home Folder to the external drive (in System Prefs > Users > Advanced Options) the drive comes up as "Thunderbay 1". To give you an idea of my setup: A 5k iMac with the external drive the OWC Thunderbay Mini Raid edition with Softraid 5 managing the external disks. The 4 disks are arranged in two sets of striped (Raid 0). Solutions I've tried: I've had the problem on Yosemite and El Capitan. With the old (Yosemite) Softraid 5 driver and the updated Beta (El Capitan) driver the problem persist. Reformatting/managing the the drive with Disk Utility instead of Softraid 5 yields no change to the prefix. Moving the user folder with Carbon Copy Cloner. Trying all of the above from my own user account and a new admin account. OWC's "tech support" last email suggested renaming the drive which I'll try tonight but don't really see the practical application being of benefit. Any other insights or suggestions into my challenge?
