It seems that NONE of the external USB devices that are on my desk (64 GB EMTEC, 64 GB and 4 GB ScanDisk, 1 TB HDD in Lacie enclosure) are supported when connected to the laptop. Only internal laptop hard drive is listed as a usable device! I cannot use this drive for experiments, I need its installed operating systems for other tasks of my work. Surely nobody in the sane mind would use USB sticks for RAID data storage but how am I supposed to evaluate your product without buying the dedicated server first? Also, all external USB devices I have tested work absolutely fine under Linux.
