Imaging non-standard partitions

Post by rustleg »

I am using a system which uses a Unix partition where the formatting isn't recognised by IFD. As I understand it, when imaging, IFD treats it as just a piece of disk space and will image the entire contents even if there is little actual data there. I understand why this should be so but would like to minimise the resulting file size.

Would it be useful if when setting up the partition in the first place I wipe it to all zeroes so that compression will keep the file size small? Would a BIBM wipe do this? Or other Terabyte utility?

You might get easier results if you use IFL Networking
version, rather than IFD. Same creation process to get a
bootable CD/DVD/SD card.

For example, I cannot access my SD card reader built in to
my laptop using IFD and I CAN using IFL.

yes. and yes, a "clear" or quick wipe of zeros would allow the areas to
compress tighter. (although not optimized for special all zeros (like
sparse), so wouldn't matter if it were all 1's 2's or 3's, just that they
are the same).
