I had a similar problem; this error message appears to be extremely
misleading since reducing the blocksize from the default value of 4K
to 1K seems to format 1GB SD cards just fine:
mke2fs -b 1024 /dev/sdcard1/disc0/part3
(I format all my TS-7300 SD cards in the bootable TS three-partition
format; this should work on any partition.) On a somewhat related
issue, after formatting, init thinks it has always been almost 100
years since the last filesystem check, so I use the following to turn
off checking the filesystem by elapsed time (it still checks by number
of mounts):
tune2fs -i0 /dev/sdcard1/disc0/part3
Hope this helps!
