Hi all guy´s. Does anybody know if the drivers for DOS USB users, the usbaspi.sys and di1000dd.sys work with large usb disk, like 160G, or what is the capacity limit of them? I believe that since they are UMS´s, they mey be able to access them, but I don´t know the maximum disk size that these drivers support. If that is right, I´ll will use it to store data as a large backup in place of DVD´s or CD´s.
Thanks in advance for that data.
Best regards.

If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong.

I think the drivers are not the problem, the problem can be with older dos versions. They don't implement large disk support so they are limited to something like 8 GB IIRC. Newer dos (FreeDos, Enhanced DR-Dos, dos subsystem of Windows 9x ...) can use more than 8 GB.
