Hi. Apologies if this has been answered elsewhere. I have been using a PDW-U1 for backup of SxS material and it has been working fine up until the other day when discs would not format correctly anymore. The disc will start to format and reach about 90% when a message box appears stating "Format Failed. (Error Code: 0xA1000007)".
I have done the following:
Used another disc;
Reinstalled latest driver;
Reinstalled latest firmware;
Changed USB ports and cable.
This disc will mount but in read only.
I am using a MacPro. If anyone can help then greatly appreciated.
