Is the drive attached to the notebook internal USB connectors,  or to a PC-Card (probably USB2)?  If connected internally,  are you loading the USB 1.1 drivers, or the USB2 drivers?

If you are not attached to the internal USB connector,  and are not using the USB1.1 drivers,  you will probably not get it to work consistently and reliably.  I have used Ghost 2003 and a USB drive once,  but I don't do that often since it is so slow.  I rememner that I had to tell Ghost to load the USB drivers,  and to assign drive letters to see the drive,  but I do the drive letter part by default to use my firewire drive (on a C800 and a C840).

Thanks JersWork for your reply

The USB drive is plugged at the back of the notebook Latitude C600 port by a USB cable. It works properly under WINXP. Norton Ghost 2003 got 3 options to reboot the PC either without drivers, using uSB 1.1 driver or USB2.0 drivers. I tried all 3 options but the PC-DOS reboot saying didn't recognize the aspi2dos.sys and then failure to assign driver.

I think its the problem of Latitude C600 notebook or the improper function of USB driver, any advice?

 

The ASPI2DOS.SYS file you refer to is the Adaptec 152x SCSI controller driver,  not the USB driver.  The USB driver loads in the AUTOEXEC.BAT file (IIRC).  It sounds like you specified to load SCSI drivers and not the USB drivers... 

thks Jerswork, but the drivers installation came from one of the 3 options of Norton Ghost :

1) no USB driver,

2) USB 1.1

3) USB 2.0

and I had tried 3 of them both could not recognize the USB drive, any more advice?

Have you already updated your ghost to the newest version and made a new bootable floppy with it? That was what I had to do to make Ghost 2003 recognize my Maxtor DV5000 over Firewire. Don't know it it will work for you on USB, but may be worth a try.

will try your suggestion and update the status.
