FAQ/057 OQAR - PN/D52000-XXXXX (all OQAR versions): Why does the OQAR display INVALID MEDIA message?
August 18, 2014
The MO disk is not compatible with the OQAR variant. For example, if you try to use a 230MB disk in an OQAR which is only compatible with a 128MB disk, the INVALID MEDIA message is displayed.
It is also worth noting that 128MB MO disks are now obsolete. To check the compatibility of your OQAR with 230MB MO disks, download SIL D52000-06
