Man, finding a fix to a problem can be nerve-wracking!  Hope someone can help. 
I have a LITE-ON  DVDRW SOHW-1633S combo drive that's been working fine until today.  All of the sudden, I get a "communication failed" and the software (Nero Ultra Edition 6) aborts the write.  Fortunately, I have two "combo" drives on this machine and they're both presenting with the same problem.  So, I assume that it's not the drive(s).  That would be too cooincidental.  I've checked all the usual stuff: cables, power, disc media, etc.  Also, I have not been able to find tis problem (or fix) in the many Tech forums that I've checked.
I'll give you all the specs first;
CD-ROM: LITE-ON  DVDRW SOHW-1633S\Version: BS0S - HA 1 TA 0 - 6.6.0.13
Adapter driver: atapi,   HA 1 , atapi Port 1 ID 0  DMA: On
 
The OPTORITE DVD RW DD0203 specs are similar (`cept it's the slave on this IDE channel)
atapi Port 1 ID 1  DMA: On
I'd like to post the Nero log for anyone up to the challenge, but this forum won't accept text files.  If you think you can help, just reply and I can email the files.  I'd like someone to be able to tell me that these drives are well and truly "Tango-Uniform" before I go out and buy new ones.  Can anyone help?!  Thanks in advance.
