Hi, sorry for lending the thread. But I have the same problem with my NEC 2500A 1.07 and my brand new Verbatim DVD-R disc's.
I get this error:
[1:0:0] _NEC DVD_RW ND-2500A 1.07 (J:) (ATA)
CDB: 53 00 00 00 00 00 22 A2 81 00
CDB Interpretation: Reserve Track - Sectors: 2 269 825
SENSE: 70 00 02 00 00 00 00 0A 00 00 00 00 30 11 00 00 00 00
SENSE Interpretation: Cannot Format Medium - Unsupported Medium Write Speed
Failed to Reserve Track! - Cannot Format Medium - Unsupported Medium Write Speed
I've checked the media code for the discs on the webshop i ordered them from: media code: MCC03RG20/TYG03
I hope that someone can halp me with the problem.
