Share your knowledge on these two classic MPCs

Does anyone know why I can only create (mode 0 = MPC3000 standard partitions) 9 or more but no less partitions on a 256mb compact flash card?

I have tried the hybrid partitions option (mode 1) on another the card of the same size and there is an option of 6 partitions.

I wanted to keep one card for MPC only and the other for transfer. Thanks . . . .

Standard MPC partitions have a maximum size around 30MB.

You can't have less than 9 partitions because that is as large as each partition can be.

Ok I see. In my case each partition is 28mb. So it must vary . . . .

Also can someone explain in layman's terms the difference between software low level format and the hardware low level format? Thanks again

It does vary, it splits up the available space into a number of equally sized partitions, to a maximum of 30MB each, so 256MB divided by 9 partitions = 28.44MB per partition.

It will not let you go to 8 equally sized partitions, because on a 256MB card, they would be 32MB each, which is over the 30MB maximum partition size.

:arrow: DISK FORMAT SEARCH

http://en.wikipedia.org/wiki/Disk_formatting

Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is often referred to as "low-level formatting".[1] Partitioning is the common term for the second part of the process, making the data storage device visible to an operating system.[1] The third part of the process, usually termed "high-level formatting" most often refers to the process of generating a new file system.[1] In some operating systems all or parts of these the three processes can be combined and the term "format" is understood to mean an operation in which a new disk medium is fully prepared to store files. Illustrated to the right are the prompts and diagnostics printed by MS-DOS's FORMAT.COM utility as a hard drive is being formatted.
