RDC 2882 LANDISK

Regarding RDC2882 V49 firmware for LANDISK devices
RDC is writing that it’s a beta test version and they did not ‘publish’ it to the public
The reason for the release is a problem in the SAMBA function in MAC OS 10.5.1 however it seems that in MAC forums people write that there is more or less a bug in 10.5.1
compatibility problem…..so, MAC OS released 10.5.2 version to solve this
It seems that the NAS-BASIC48 firmware is just working fine with the 10.5.2 and that is one of the main reason they did not release NAS-BASIC49
