[SunRay-Users] SRSS 4.1 USB storage problems

[Bob Doolittle]

Did you try formatting the sticks under Solaris (or Linux)?
Does Linux handle them if you plug them directly into the Linux host?
I don't know about Linux, but on Solaris we rely on pcfs, and it can be 
finicky.

Do the sticks that fail require special software under Windows?
Often flash disks these days come with proprietary encrypted partitions 
that require special Windows drivers to access.

Those should be accessible under Windows via Sun Ray Windows Connector 
in our next release. If you don't want to wait or you need to access 
them natively then reformatting them may be necessary...
