Just after a quick bit of advice....
Have just flashed a Hitachi 0078 using Firmware Toolbox V4.6. No problems all the way through - ok into Mode B, Followed the instructions to the letter as per "The Textbook". All successful - all as per the pdf.
However trying to plaback, originals work fine. Backups refuse to work, however i know they are ok as they work in a different machine - it just comes up with "unreadable disk" on this one.
Anyone any suggestions??
