NTFS for USB Keys

Hi There

This may seem a little strange but here goes.

Say for example you want to move a file between two computers securely on a USB key. USB keys default to the FAT filesystem which offers very little in the way of file security. If you loose your key, anybody can view the data on it.

What if you formated your key in NTFS? then you could set file permissions on just the users you want to be able to access the data! Even encrypt it without special software!

Please note this tutorial is for users of Windows XP / 2000 and if you follow it your key will NOT be readable on Windows 95,98,Me etc. untill you reformat it in FAT.



Heres how to do it:

1) Move everything off your key into a backup folder.

2) format your key in FAT by right clicking its icon and choosing format and doing it in the similar way to formating a floppy disk.

3) when the format is complete click Start > Run > Type "cmd.exe" and click ok.

4) type the following EXACTLY:

convert E: /fs:ntfs

where E: is the drive letter for you Usb key.

Wait a few moments and the file system will be upgraded.

5) Copy your files back to the key and set appropriate permissions on them.



I hope this tutorial helps peeople who want to keep their data secure on a removable device.

for an excellent tip MeV1 - very useful, although it's fair to say that many USB key drives come with file protection facilities built in, or there's often downloadable password software protection available from the manufacturers' web sites.
