Re: [Ensoniq-VFX-SD] Re: disk format problems

2008-02-06 by Ted Morris

I have a small problem with your "tape the hole" system....
Its not the disk that is bad... it's the difference between the drives...
Yes a 720k drive formats the disk in 720k increments
Yes the 1.44 drive formats the disk in 1.44mb increments
But mostly, the system you format the disk with, changes it so it can be used in it.
It might not work in another system
But a 720k format does not work in a 1.44 drive even if you are successful in doing so.
and a 720k drive does not format on 1.44 unless your operating system supports it. and vice-versa
And most 1.44 disks are pre-formatted with a dos format which is 64k, and are not system system disks at all until they are re-formatted.
And most system disks are 2mb and application disks are usually 1.44mb.
720k disks are early data system disks, that use compacted directory paths to store the data in machine code...the data is called discardable data.
1.44mb disks were the first system disks to store application data like dos and windows. this led to a revolution of system OSes that use primarily the same format principles of the 1.44 and it is truley a secret. I studied the assembler system from IBM and early DOS. and the disk format principle is really something to see on paper believe me...(I think that's why I like to collect rocks....and play music....)
