Shrinking SD card image size (remove unused space) to fit into smaller card?
I've got a working and slightly customized ClassicWB installation for my A600 (Furia etc.), which is working really fine. It has 3 partitions, roughly 8 gigs of stuff with PFS3AIO.. Originally I used a 32GB card, because I had one So, there's 24GB unused space on the card. Stupid me
I tried to make an image of the card using Win32DiskImager and tick the "Read only allocated partitions", but then it doesn't so anything. Without ticking the box it makes a image, but of course it's 32Gb... I checked the sizes of the partitions from WB, so I'm positive that the partitions are only ~8GB all together. How can I (or can I?) shrink the image to git let's say to 16GB card or even to 8 GB card? A friend would need a test setup for ACA500 and It would be nice to use the existing CF:s lying around.

I doubt you can through Windows. One option is to make another HDD file and copy files across using WinUAE.
@thomas did some work on HDD and I can't recall whether it involved partition sizes... |

I mean with a correct size image it's really easy to just restore it to a new card |

If you are 100% certain there are no partitions extending after the point you want to reduce it to, you can cut the file with a suitable file manipulation tool. (or file splitter). Or just write it to a smaller CF card with an imaging tool that doesn't have an issue with the destination drive/card being smaller than the image.
The RDB will still say the card/image is 32GB, (as shown in hdtoolbox, etc), but this can be fixed by running fixhddsize from aminet. This tool can update the RDB to the correct size. (It cannot resize partitions) |

Try WinImage , you can write your larger image to a smaller SD or CF card, it will come up with a cycling error error after writing but it will have copied the RDB and you will then just have to check using Winuae or a real Amiga how much of your data has been copied and if your lucky most of it should have, link below
