Anybody know if there exist adapters for old disk drives (e.g.- MFM, RLL etc.) to USB? Preferably USB 2.0. I may need to read the contents of a bunch of old hard drives. I can probably cobble together some old ISA systems with the right controllers if I really must, but maybe someone's created a simple solution. Chris -- This same subject came up a month or so ago. You have to use the same controller as the drive was formatted with, since there is no way to tell what the actual on-disk sector format was for a random MFM or RLL disk. Adaptec, for example, used their own ECC scheme on the sector. There is (currently) nothing available like the Catweazel for capturing bit level data for hard drives.
