-minfo may give the same results even while you use completely different media.
The media manufacturer and media sub-types are displayed by cdrecord -atip

In this case (-atip), your problem is not related to the media but to
the USB drivers.

This is a Solaris USB kernel driver bug that I reported a year ago and that 
does not seem to get fixed. It may help to try out a different USB<->ATA/SATA 
adaptor.

It is sufficient to replug the USB cable to "fix" the hang inside the kernel.

You may try to use the USB adaptor from the Plextor drive ;-)
