My windows xp pro crasshed and Need to copy my documents from c:\prompt to usb external drive. How can do this? the boot sector es damaged in the drive, but i was able to got into de Dos. Help please thanks

How did you determine your boot sector is damaged? FYI there is no DOS in WinXP. Describe your situation and post your computer model.

I use Live CD/DVD's or bootable flash drives or pxe booing. One of the BEST is Knoppix 5.1 cd. openSolaris to Ubuntu also have live cd's that support many usb devices. I try to keep some barts/ubcd4win's around too. I can use Vista or W7 with a few tricks but not real easy. "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

From the C:\> prompt type cd docume~1 and enter. The prompt should now read C:\DOCUMENTS AND SETTINGS>. Then type dir and enter. Look for your user name. Type cd user name and enter. If your user name is more than one word or is longer than eight letters type in the first 6 letters, ignoring any spaces, and add ~1 to it. So if your user name was 'John Doe' you'd type cd johndo~1 and enter. The prompt should now show C:\DOCUMENTS AND SETTINGS\USER NAME>. Type cd mydocu~1 and enter. The prompt should now show C:\DOCUMENTS AND SETTINGS\USER NAME\MY DOCUMENTS>. Type xcopy *.* x:\ /e and enter, where x: is the drive letter of your USB drive. That will copy the contents of your My Documents folder, including any nested directories, to the root directory of your USB drive. Note that if you use a boot CD or floppy bootdisk rather than getting to command prompt via the boot menu, the drive letter of the USB drive may be different than when XP loads normally.
