More Information for MFM Drives
I know that we have already discussed the MFM drives couple months ago,
but I want to give you the consideration about one or more ideas to overcome
the hardware's design. Please try to answer only one question below.
MFM controller card is designed to detect the beginning header bits
before it begins to read only 512 bytes at this time. The hardware's design
does not allow me to manipulate by reading each bits instead of bytes
however it has its own manipulation.
Is it correct to my one question above?
If my question is answered yes, it means that there is no way to FORCE
hardware's design to be modified in order to manipulate. For example, it
can only read/write 720KB and 1.44MB. It does not allow me to modify the
size such as 800KB and 1600KB. If it is to be Universal (Not USB) MFM
drive, yes, it will be possible to modify the size.
It is my goal to begin to design and build USB device driver that will
support ANY sizes including GCR + MFM formats by using low level through USB
device driver which it is the independment hardware rather than
stupid--old--traditional MFM hardware.
What do you think? Please advise.
