Mkef2s Warning And Error

[DrSteve]

Hi folks.  Installed e2fsprogs and the -mke2fs component via ipkg from the feed using the console.  Seemed to install with no issues.  

I'm trying to use mkfs.ext2 to format my 64MB Sandisk SD card so I can install a few programs there with the appropriate symlinks.  I get the following from mkfs.ext2 /mnt/card:

mnt/card is not a block special device.
Proceed anyway? (y, n) y
mkfs.ext2: Device size reported to be zero.  Invalid partition specified, or partition table wasn't reread after running fdisk, due to a modified partition being busy and in use.  You may need to reboot to re-read your partition table.[/font]

Guess I'm doing something wrong.

***EDIT***  Should note I did reboot after getting this message the first time; rebooting didn't help.

Here's the instructions:

/mnt/card is just an empty directory (until you mount the fs on it)
/dev/mmcda1 is the device entry for the partition

I got a similar error consistently with my Adata 150x 512MB SDcard. A PNY 512MB sdcard works perfectly with the exact same commands I issued with the adata card. Is it a timing issue or something?
