When I connect via USB a My Book Duo (with two NTFS-discs in JBOD mode) to the EX4 - I see message “Unsupported file system” on LCD screen and in eventlog of EX4.
Similarly problem I have with USB-connection this My Book Duo (with two NTFS-discs in JBOD mode) to the WDTV of last generation. However in this case WDTV can see My Book Duo, but just with only one disc of two.
When I connection this My Book Duo reconfigured into RAID-mode to the EX4 or WDTV - I not have any problems.
WD - Why??? How it possibe, WD NAS not work with WD DAS (when DAS set in JBOD mode)???
Any firmwares in my WD-devices is last version.
WDC please, Fix it!!! I cannot work my job without this!
