Plese some help with DW-U14A Sony recorder

Hello, I upgrade the firmware of my DW-U14A to DRU-510A. Althought the upgrade was OK, the recorder don´t work well and Nero stops recording with a “Error writing disk” message. I try with different firmware version of the DRU-510A, but nothing… Yesterday I find the original firmware of the DW-U14A (1.0d), but the upgrade shows a “No updaptable drives exits” message
Please…something know how to back to original firmware??

Downgrading will not help the problem… :frowning:

Thanks, I play with master/slave configuration, and seems that now the recorder works well.
