You can get the erase block size from SD cards - it's in the Card Specific Data structure - but I don't know of any standard way to get it for USB mass storage devices.
Ah, now you mention it I remember. :)Not sure I would trust it, though: It's limited to 256KB by the SD standard (max. write block size 2KB, max erase block size 128 write blocks) and even my 16GB card sets the write block size to 512 (=> erase block size 64KB).
I've put up a script for reading the erase block size in Linux at [1]. [1] http://sascha.silbe.org/tmp/printcsd.py CU Sascha -- http://sascha.silbe.org/ http://www.infra-silbe.de/
