Thanks for your kindly help last time, I found a new strange problem when I do format disk action with Disk Utility, there's two choices in OSX 10.3 Disk Utility, 'Zero all data' and '8 Way Randon Write Format', our USB 2.0 card reader driver would seriously crash when I choose '8 Way Random Write Format' mode to erase the removable flash cards.

If I can make one suggestion, you shouldn't ever need to use the 8-way overwrite with a flash memory product. As there is no surrounding ferrous oxide material with which to retain previous state alignment, and as flash memory products have a limited number of writes before they're no longer usable, an 8-way overwrite is both unnecessary and harmful.


Still, I can understand wanting to prevent a crash, but you might want to document for your users that formatting that way isn't a good idea.
