Strange device name for JMB RAID

[Heinz Mauelshagen]

Hi Mark,

Looks like a flaw in the string code to handle device names.

Can you create metadata samples (preferably in an empty directory) by running
"dmraid -rD", tar/bzip2 them up (ie. "tar jcvf JMicron-Mark_Junker.tar.bz2 *")
and send the tarball to me for analysis, please ?

Regards,
