Glad to hear you flashed your Memorex successfully. I'm not sure exactly what you mean by wondering if it is possible to send a picture to the CDRLabs forums. Does this answer your question?
As for the F1, Yamaha has some fairly explicit instructions in the readme file and on the download page:
http://www.yamaha.co.jp/english/product ... fw-10.html
Three things they mention are to make sure that auto-insert notification is turned off on all drives that share the F1's IDE bus, to make sure that no disc is in the drive, and to make sure that DMA is disabled (in other words, set the IDE transfer mode to PIO before flashing).
I don't flash my drives as a matter of course like some people do. I only flash them when there is a known benefit to doing so (just my personal style - not a knock against those who flash early and flash often!
). In the case of the F1, I think there is a worthwhile reason to flash from 1.0c to 1.0f, because you get added 24x and 32x manually selectable burn speeds and improved rewriting quality for 16x and 24x CD-RW discs.
