Panasonic DVD-RAM incompatibility with 4551A



Hi to all ,
my Nec 4551A doesn’t recognize mostly of Panasonic DVD-RAM (id. M01J3003 and/or 3004).
Only sometimes I can to save on this disk my datas , no ideas ?


No ideas. Update software & drivers/firmware.

Mine has no such problems.


Unique Disc Identifier : [DVD-RAM:Matsushita Electric Industrial CO.,LTD.-M01J3003]

Disc & Book Type : [DVD-RAM] - [DVD-RAM]
Manufacturer Name : [Matsushita Electric Industrial Co. Ltd.]
Manufacturer ID : [Matsushita Electric Industrial CO.,LTD.]
Supplementary Info : [M01J3003]
Formatted Capacity : [2,236,704 Sectors = 4.58 GB (4.27 GiB)]

** INFO : Drive = _NEC DVD_RW ND-4551A - [FW 1-07] - [ATAPI]

Works fine to me.
Must be a software/driver issue.



I have some questions concerning dvd-ram:

  1. How fast can you burn this dvd-ram disc (in MB/s)?
  2. What dvd-ram drivers are you using?
  3. And with what file system (udf 1.5, udf 2.0, fat32) is you dvd-ram formatted?



Thanks for the picture. And what about other 2 questions?


I’ve had two MadDog/NEC 4550As. The first one wouldn’t write to DVD-RAM worth a damn. I got a better deal on an external so I returned the internal, and this one works far better on DVD-RAM. In both cases the Firmware (either stock or Liggy’s 1.07BT) didn’t make a difference.

IOW, it might be that particular drive- try exchanging, if you can.


I’ve no probs so far with Pana discs, this brand was one of the first two recommended by NEC
