...or > images, not for hardware devices, and it doesn't make much sense to zero > the whole hardware device like that. Maybe for privacy reasons ? But indeed: -s should skip zeroizing, regardless of truncate. Additionally the argument of truncate is currently wrong by a factor of 512: $ mkdiskimage_orig.in -s image.img 250 64 32 $ ls -l image.img -rw-r--r-- 1 xyz xyz 512000 2014-01-28 08:33 image.img How about this ?

Hi, i too played with mkdiskimage in order to get more Linux examples. When i applied it to a real 2 GB stick with write speed 4 MB/s i had enough time to add some pacifier code to the big zeroizer loop. (-s does not prevent zeroizing on block device. Probably because truncate() fails.) My pacifier is combined with what Perl advised me when i tried "fsync(OUTPUT);". Of course this

Hi, following is a series of patches derived from my proposed diff. Based on syslinux-6.03-pre1, but should also apply down to 4.xx. I hope to have imitated the changelog style sufficiently. Mine are a bit longer than usual with patches in the archive, i fear. Instructions for the future are welcome. Each intermediate state is tested for its designated purpose only. The final state after

...as 0. (In the other cases, the unclaimed space might be much larger than a cylinder. For those i would propose a new option -A, if ever.) I can make single-issue diffs, if desired.
