I tried it a couple of times. On a system with a nearly-pristine NAND image (200+ MB), the process took about 16 minutes. I tried it twice and go similar results both times. The USB device is a Verbatim 1 GB USB 2.0 FLASH key. Prior to the test, I recreated the partition map by using fdisk to delete the existing partition and to create a new on of type 0x0c (FAT 32) of maximum size. Then I inserted the key into a Windows XP system and formatted it as FAT32. I was using q2c26x, which is my latest experimental firmware. I don't it has any differences from q2c23 that would affect save-nand. If your USB disk were being detected as USB 1.1 instead of USB 2.0, that would cause extreme slowness. > > The next step, which is new since 406, is that you also have to create > a .crc file. > Scroll to the bottom of this page: > http://wiki.laptop.org/go/Customizing_NAND_images > <http://wiki.laptop.org/go/Customizing_NAND_images> > > I had to get someone to build the crc for me since I didn't have a > build environment.
