I'm sorry, I should have explained posting images. You simply click the small paper clip icon(attachments) in the top row of the tool bar and a selection box pops up to choose the files on your computer to upload. Those JPGs are clear enough.
The bottom scale represents 0-80 for a standard 80 minute CD-R. The vertical scale at left represents the read speed from 0-48x. The red line indicates the end of the data area that is burned on that particular CD-R.
Glad we took a minute to test your drive. Bad news is, that is a good reader. There is no indication that it is struggling to read those CD-Rs. If it was, you would see something like this on your read speed graph. The read speed would drop down along the way rather than smoothly rising to the end.
The reason that the read speed starts slower and rises is due to the read strategy employed by drives, constant angular velocity. Essentially, the CD spins at a constant RPM, but as each spiral gets longer starting from the center, each rotation of the disc transfers a little more data than the last, and the data transfer rate keeps climbing until the end of the data on that disc is reached. You will not see the transfer rate of 48x that your drive is capable of unless you run into a CD-R that is burned almost to it's full capacity.
With the average transfer rate of a good reader like yours only being in the 4-5 MB/sec range, I'm afraid that the media is to blame for your wait.
Unless you can convince them to start burning DVD-R(around 12 MB/sec) or use fast flash drives, I think you may be stuck with that 30 sec. to 1 minute wait.
