True. Working on that. > I also think they have hard coded 512 bytes per sector. No. USBDRIVE reads the maximum buffer size from the DOS List of Lists (as discussed some earlier in the thread), and uses that as its maximum sector size. If a USB disk has 4k sectors, but DOS can only handle 512 byte sectors, USBDRIVE won't load the disk. If DOS can handle (buffer) 4k sectors OK, USBDRIVE will load it and automatically mount any FAT partitions it finds. Also as stated earlier, I don't personally have any disks with sector sizes other than 512, so this has never been tested (at least by me) on a real system. That's why you need to modify the kernel to handle 4k sectors, also as discussed earlier (at least with my drivers). Based on what Eric says, though, that doesn't work with the FreeDOS kernel. Because USBDRIVE provides an INT 13h interface, you can also use external drivers to mount/access the non-FAT partitions that may be on the USB disks (NTFS, EXTx, exFAT, ...). USBDRIVE won't mount non-FAT drives automatically, though. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
