Using 2 TB external drive

[suzannetins]

I am new to mac and have all new mac machines, 2 laptops and a desktop.
I have 2 1 TB external hardrives in an enclosure formatted to mac journaled

I successfully transferred one folder the first time I used it but now when I try to transfer I either get the 05 error but mostly the error says my file names are too long.

I know there is a simple fix and would appreciate any help.
Thanks

You're sure they're formatted to Mac OS Extended (journaled)? You can check by selecting the drive in Finder and going to File -> Get Info.

Thanks for your reply.
Yes they are Mac OS Extended (journaled).
