At least with the Mac, this isn't a good idea for long term use. It will sometimes format the disk as DD if you tape over the HD sense hole, but even if it does, you can pretty much count on the disk failing in a very short period of time. I've never had a disk last more than a few read/write sessions. After that, errors start occuring and you can't read or write to it any more. In many of the cases, the disk is usually hosed after this and won't take a format back to HD anymore. I can't say that I've really tried it outside of a Mac, so it might just be a Mac thing that keeps it from working. And despite the fact that some company made a hole puncher to make DD disks into HD disks (I have one), that doesn't seem to work any better on the Mac. In fact, in my findings, it works even worse as it rarely ever even took the HD format in the first place, and when it did, it immediatly starting having R/W errors and was unusable anyway. -chris <http://www.mythtech.net>
