Hi all, thanks, Chuck, for pointing to my website with the 604 drive, but it's currently offline as I am required to update the disclaimer part. This is required, since in Europe,a new law for data protection was introduced on Friday, 25th of May. I plan to put the website back online this weekend.

Nope. I've seen 248 mentioned and I have period-specific tapes that are declared to be 200 bpi on the label and then there's this: http://www.digitalheritage.de/peripherals/cdc/604/604.htm Note the density indicators on this panel from a CDC 604. --Chuck
