Both ways work equally well, but the second way is slower but safer (since it doesn’t change the source SD Card). You then do the shrink operation on the disk image, make a clone of the disk image, and then restore that image to the new SD Card. ![]() The second way is to make a copy of the original SD Card to a disk image so that you are not making any changes to the source SD Card. The first involves shrinking the filesystem on the original card, making an image of it, then restoring that image to a new card. ![]() SD Clone makes this operation easy, and has 2 different ways to accomplish it. The card can then be copied and the last partition on the new SD Card can be expanded to take up all the remaining space. The solution is to shrink the last partition so that it is only as large as the actual space being used. Copying an SD card from a smaller card to a larger card doesn’t have this issue, but it you lose the additional space (not a big deal if it is only 0.02 GB, but is a bigger deal if you are going from a 8 GB card to a 16 GB card). This can lead to corruption and problems with the new SD Card. However, if the new card is slightly smaller, the operation will fail since the last partition on the original SD card cannot be completely copied. If you install an operating system on an SD Card and want to make a copy of it, the simplest way is to get another SD card and do a byte-by-byte copy of the card. Normally, this isn’t an issue, but in some circumstances it can be problematic. I also have a Kingston SD Card that is advertised as 8 GB, but it has 7.97 GB of available space. For instance, I have a SanDisk SD Card that is advertised as 8 GB, but it has 7.95 GB of actual space. However, two cards that have the exact same number of GB’s (for instance 8 GB) advertised might not have the exact number of available space. ![]() When you purchase SD Cards, they are advertised as X number of GB’s. If you do any work with the Raspberry Pi or other Linux based system that uses SD Cards as the primary storage device, you’ll run across a issue that can be time consuming and troublesome.
