I think that d2s does not cares about SD card format. It just writes a header and dump data from flash to SD card's sectors.
So you don't have to format anything, or create any partition on your card! just dd the original saved data on the card, it does not follow any partition/FS format. you have to dd it to /dev/sdb, not /dev/sdb1 we're ok?
I found somewhere on hh.org hx-4700 wiki that a saved wince4.2 image was around ~130 MB, so even if you transfer the first 256 MBs from your 1GB card to a new 256MB card, it will work without problem.
Anyway, I think the main point here is to realize that d2s backup does not care about filesystems and partition tables. It's just raw data blocks that you can read from the block device /dev/sd<letter>.

Hi Sébastien
I've just tried reset with/out the SD card in, without any luck.
How can I verify my img file created with d2s originally onto a 1GB SD
card (now reused)? I have a CD with gz'd copy that I originally d2s'd
and have dd'd it to a 1GB SD card. The gz'd file is 27.5MB whilst the
extracted img files is 98.2MB!! That is, it will only fit on a 1GB SD
card ... ?
Note: I prepared the orginal 1GB SD card on an (and, rescued for the
purpose) XP PC. I couldn't get a Linux format SD card to be read by my
hx4700. The latest 1GB SD card was similarly format'd on an XP PC - but
when I verified it, with "fdisk /dev/sdb1" on one of my Linux PCs, the
partition table was a real mess. I've corrected this, with fdisk, and
re-tied the whole process with the hx4700 without any luck ...
Can anybody send me gz'd working img file that I can restore to my
hx4700 in order that I can sync my newly purchased Mobile 5.0 to it?
Unless, of course, I'm still doing something blatantly wrong ...
Regards
Brian
