If you create a partition in the partition table it points to a part of the harddrive or memory card which does exist. And memory which does exist has some value. If the manufacturer decided to create the memory with all bits set, then FastFileSystem unfortunately interpretes it as "no disk in drive". So you have to change the contents of the memory before you are able to write something else to it. Writing to the beginning of the harddrive (to the partition table) does not write to the beginning of the partition. But you have to write some value other than 0xffffffff to the beginning of the partition before the Format program allows you to proceed. It does not matter which computer you use for that or which AmigaOS you install on the first partition.

Checksum errors on a freshly installed IDE harddrive or memory card usually are caused by a too high MaxTransfer value.
