Because they might be more difficult to obtain than the parts for building a custom 6502 computer? On the other hand, building everything from scratch is more expensive and time-consuming. > Nonsence! Just think how an emulator uses his emulated 1541.

You can call the disk images files or partitions; the reality doesn't change: you will have to divide the hard disk to hundreds or thousands of disk images in order to use it in that way. A higher-level file system, without any 1541 compatible block-read or block-write commands or file structure is necessary. The reality is that using 2-byte sector links in the beginning of 256-byte sectors limits the maximum file (and disk) size to less than 16 megabytes, which is less than 1% of the capacity of modern hard disks. > I give you the ideas I'm thinking of (for the moment): > - 32-bits FAT, a cluster = 1 sector.

I wish you good luck with the project. I don't want to discourage you from doing it; I just wanted to point out some things that might become problematic later.
