I have spend a lot of time looking through the great posts and replies related to DOS seeing external drives. My main goal is to write a ghost image to and external HD (Toshiba 2.5in 80gb in a generic case). My boot disk is a dos6.22 version created using roxio disk creator (boot disk creator, 1.44 FD Emulation) with the drivers. I have an HP L2000 (Compaq V2000) that uses the Phoenix bios v6, which has very few options (no options related to USB). I am using the following config.sys lastdrive=Z device=\HIMEM.SYS device=RAMFD.SYS rem The following line loads Panasonic's universal USB- controller driver device=USBASPI.SYS /v rem the following is an aspi mass storage driver for usb- connected HDs device=DI1000DD.SYS I tried with RAMFD and without.And various switches on the usbaspi driver The first error is "ECHI memory mapped I/O can not be assigned" but it will find the Toshiba external HD under OCHI (I can live with that, I think) "DI ASPI Disk Driver ver2," "Available ID = 0" "ID 0 = HD ..Toshiba MK8026GAX" But does not assign it a letter to the HD It will however assign a letter to a thumb drive when attached. It then shows the A:\ prompt several times and locks up. I am now at my witts end! I don't know what else to try. Thanks in advance for any suggestions

DOS 6.22 will only recognize FAT16 partitions. If at first you don't succeed, you're about average. M2

ROXIO is Windows Software Norton Ghost is Windows Software OK Norton Ghost and Acronis True Image actually can create USB Boot Disks, the later being more reliable as based on *NIX So if using Windows Software with USB features, why messing with MS-DOS 6.xx which has no FAT32/NTFS/LFN compatibility ?? It will only recognise FAT16 2GB partitions, not much use for a 80GB HDD !!

Amazing what one finds when searching the Disk Op Forum: http://www.computing.net/dos/wwwboard/forum/15936.html http://www.computing.net/dos/wwwboard/forum/15928.html http://www.computing.net/dos/wwwboard/forum/15925.html http://www.computing.net/dos/wwwboard/forum/15915.html http://www.computing.net/dos/wwwboard/forum/15888.html http://83.67.55.228/USBDOS.exe Though this whole post would be more appropriate in a Windows Forum, would it not ?
