This may be a well-kown problem; if so, I apologize for bringing it up.
I’m finding that the 165h (ch0q f/w) doesn’t handle blank CDRs at all well. First, it tries to read them for a pretty long time and then seems to decide that there’s no disk there. So both CDRidentifier 1.63 and the CD-R Info dialog in CDSpeed don’t work at all. Also Windows Explorer sees the drive as empty.
I wonder if this is normal behaviour for this drive, and whether there’s some fix.
