So Ive read somewhere but dont remember where that a person should NOT format partitions using the full format option other than the System partition, using Quick format instead. Is this correct?
1. full format does nothing useful to the drive. There is no way for an application program to format a SCSI or IDE harddrive. Instead of format the program does just write. And write and write and write and write and write for a very long time and with no use at all.
Quick format does the important work: it initialises the file system
2. the format programs which come with Workbench up to and including (I think) version 3.5 are not able to format anything outside the first 4 GB of the harddrive. If your harddrive is bigger than 4 GB and you try to full-format a partition which resides outside the first 4 GB what happens instead is that areas of other partitions inside the first 4 GB are overwritten. The data which was there before is destroyed. So it is very dangerous to use full-format on harddrives bigger than 4 GB.
Because it is of no use anyway, the suggestion to avoid full format on everything except floppy disks is always valid. Quick format is just that: quick and sufficient.
And there is no FAT in the Amiga file system.
