I have an ND2901 and getting error code 8023? Tried updating to latest firmware but still have same error code. The drive reads the CF card but when attempting to copy the code comes up.
That means the file system of your CF card contains trash value which might be caused by Virus.
Format the CF card then it will work at next time.
If you have data in the CF card, connect it to computer then run anti virus program, also run windows 'chkdsk' command at cmd promt.
