Hi i got a new 20 gig harddrive and connected it with my old 4 gig and i tried transfering all the information with xcopy but all it missed hidden files and long file names, can somebody help me on a way to transfer all my files to another harddrive in dos?

If you bought the drive new, there is probably an included bootable floppy disk that will help you do it. Western Digital has DATA Lifeguard Tools, Maxtor has MaxBlast. If you got the 20Gig somewhere other than a retail store and don't have the disk, look on the manufacturer's site. There will be a download for the utility to help you transfer the info from the old drive to the new.

If you have long filenames and a 4Gb drive, this isn't a 3.1 problem. Anyway, try booting into windows. xcopy will use xcopy32 which will keep your long names for you. If you use the /H switch, it will copy the hidden files as well. If in doubt, xcopy /? will give you all the switches.

The computer will not boot into windows thats my problem, i tried setting the 4 gig as master and the 20gig as a slave but it wouldnt detect both, when i did it the other way around it would work

The version of Disk Manager for Fujitsu drives includes FileCopy which'll run in DOS3.31 and higher or Win3.1/9x. It will copy a whole drive's contents to another, including long file names, FAT16 to FAT32 or vice versa. It's 85kB, included in this 825kB download, with which you make a bootable floppy and then copy off filecopy.exe (unless you need the rest of the Disk Manager for a Fujitsu drive).

the best way is to use Drive Image 5.0 from pöwerquest or drive image 2002 if you have windows XP it works with every windows it works great and it makes a perfect copy this software permits you to make an image ,resture an image or copy drive to drive

But FileCopy will do the job in DOS and is almost legal to download for free. Can Drive Image do the job in 85kB ? ;-)
