thanks. it's totally accecptable to wipe a SD card. the "palimpsest" in this article is in the debian "gnome-disk-utility" package. search it with google, i also find this article useful: https://wiki.archlinux.org/index.php/SSD_Benchmarking i don't think "echo 3 > /proc/sys/vm/drop_caches" is a good idea. mounting a fs with the flag "sync" disables it's buffers, doesn't it? if dealing with raw device is the case. one can always use $ dd if=infile of=/dev/raw_block_device seek=<offset> to write to any part of that device. i'll run palimpsest on my cards tomorrow to see if it's results cover everything i want.
