i've been trying to get my usb harddrive to work in dos i've got all the drivers but get the error message i think from the di1000dd.sys driver saying found many aspi host adapters and then something saying put adapter number by option switch (/h) can someone tell me what this means and how i can fix this

http://www.computing.net/dos/wwwboard/forum/13681.html http://www.computing.net/dos/wwwboard/forum/13679.html http://www.computing.net/dos/wwwboard/forum/13654.html then read the USB posts in page 2,3,4,5,6 etcetc should be there somewhere!

I suspect USBASPI.SYS can only handle 1 instance of an ASPI driver or host adapter at a time (regardless of the number of drives installed per host adapter). You probably have other adapters (like SCSI controllers for storage, CDRW, scanner) on your system. Do try the /h switch - you'll need to identify which adapter corresponds to the ports your USB drive will be connected to.

thanks for the quick reply maybe i should have said it was on a laptop that might help. i've looked through all the posts and can't find anything that actually tells me anything about the /h switch. when the usbaspi driver runs through the scan the results show 1 device which i took as being the usb port but then the hdd driver d1000dd fails with the error is the h/ switch used on this driver

You are referring to this error message which USBASPI.SYS display. WORNING : Found many ASPI host adapters. Please put on adapter number by option switch (/H) However, I haven't encountered this myself, so the best bet is to try and "guess it" as many of us do ;-) Usual formats for options could be: /Hn /H=n /H:n where n is the suspected adapter number HTH

thanks i'll have a try. i'll let you know the results

still no luck i've tried using all different combinations of the h/ switch but always get an invalid switch error.its actually getting quite frustrasting now as i've tried everything yet still can't find success could it be that i'm using a standard 2.5 hdd in a caddy anymore ideas would be greatly appreciated
