  MFM hard drive formats only 10/20 MB...w by Bill Degnan - 02/13/2007 19:36
USing an IBM XT 640K with an IBM 1816101 hard drive controller and a Rodime RO204 hard drive.

I "low level" formatted the drive using the IBM XT reference disk and fdisk'd with DOS 3.3. I then ran the format command /s. There were no errors, the correct number of cylinders were counted off (320cyl, 8heads) appeared.

For some reason it formatted to ~10MB not ~20MB. Do you know why that happens?

More on the Rodime RO204:
