Unable to read DVD-R Format in N210

 Hello,

We are assisting a client that has a Netra 210 server and have encountered some compatibility issues reading DVD-R formatted disks.

The server can recognize the DVDRW device pn: 371-0101 (X8214A) when doing a probe scsi . It can also boot and run +R discs.

The issue is limited to reading -R format.  In some occasions, we can run  -R disk 1, however aprox 30 minutes into

the install,  it will not read  the next disc 2.   If we try format the disks using a PC, it seems to work better, but not consistent.

Any suggestions or advise on resolving this issue.  Our application requires -R format.
