Partition sizes for Amiga OS 3.1 (SCSI)?

[danbeaver]

There is a raw, unformatted size for a drive and after a format lays down the file system there is a much lower size; this is why the Amiga got 880K from a floppy DD, Apple got 800K, and IBM got 720K.

This does not apply to harddrives. They are formatted by the manufacturer and have a fixed number of sectors. All of these sectors are available to the operating system.

So the low level format size of a hard drive determines the end capacity regardless of the type of file system, cluster size, ECC overhead, etc.?

[danbeaver]

So the type of file system, error correction, sector size, allocation size, file allocation table, all take essentially nothing away from raw storage capacity of the drive?  Odd, I've never heard this before; tell me more.

[danbeaver]

I'm not interested in pre-allocated storage, but how a file system and all of its overhead takes virtually no space.

[danbeaver]

With GVP there shouldn't be 4gb HD limit, only limit should be  fast file systems's 2gb partition limit

So a raw hard drive from the factory when subsequently formatted in FAT, FAT32, NTFS, ,FFS, SFS, etc. on a GVP has virtually the full capacity of the new unformatted hard drive after any file system is then applied?
