I have a Thunder Bay 12 Tb Thunderbolt 3 Enclosure formatted as HFS+ and in a RAID 5 Configuration.
I bought this mostly because my iMac Pro only has a 1Tb Drive so I need to move files off my Mac to the ThunderBay as I run out of disk space. Whenever I try to copy an entire folder I get the error:
"You can't copy "Icon?" because it has the same name as another item on the destination volume, and that volume doesn't distinguish between upper- and lowercase letters in filenames."
If I copy each file individually from the source folder to the destination folder, that all works. It's only when I try to copy an entire folder or a group of folders that I get this error. It copies some of the files, but not all of them, so it's a pain to go back and figure out which files copied and which did not.
Is there another format I should be using for the Array? Also I assume this means I'll need to pull everything off the Thunder Bay Enclosure, reformat it, and then move everything back?
Any help is greatly appreciated.
Thank you in advance!
Is your source volume case sensitive? (like a Time Machine volume?)
If so, backup/erase your Thunderbay with Disk Utility, as Case Sensitive. that could be the issue.
You can also try using Carbon Copy Cloner and see if that works. it has a great free trial period.
@softraid-support My source volume is just my Macintosh HD that shipped with my Mac. I'm not using Time Machine. I use a 3rd party service to backup my Mac.
How would I check to see if my Source HD is Case Sensitive?
Thanks!
My source Volume is formatted as APFS
