There are still a few drives manufactured with write protection switches: The Imation Clip and Pivot (not Pivot Plus) drives, older Imation Swivel drives that may still be available, the PQI U339 series, and the Ritek/RiDATA Twister and Slider drives.

I have a listing of drives with links to the manufacturers at http://www.fencepost.net/2010/03/usb-flash-drives-with-hardware-write-protection/ based on information from c’t magazine, forum searches and too much reading of manufacturer spec sheets.

After reading this Article. I have this idea to create a good Trick in Vbscript.
‘—————-DummyFileCreator.vbs—————
‘Made by Hackoo
‘web site http://hackoo.ifrance.com
Dim WshShell,FSO,Drv,Dtype,Dfree,DfreeMB,Dtot
Dim Dname,Dpct,Dused,Dserial,Dinfo
Set WshShell=WScript.CreateObject(“WScript.Shell”)
Set FSO=CreateObject(“Scripting.FileSystemObject”)
For each Drv in FSO.Drives
If Drv.DriveType=0 Then Dtype=”Unknown ”
If Drv.DriveType=1 Then Dtype=”Removable”
If Drv.DriveType=2 Then Dtype=”Fixed ”
If Drv.DriveType=3 Then Dtype=”Network ”
If Drv.DriveType=4 Then Dtype=”CD-ROM ”
If Drv.DriveType=5 Then Dtype=”RAM Disk ”
If Drv.IsReady Then
If Drv.DriveType=1 Then
Dfree=Drv.FreeSpace
DfreeMB=FormatNumber(Drv.FreeSpace/(1024^2),0)&” MB”
Label=Drv.DriveLetter
end if
end if
Next
MsgBox “Espace Libre dans Le Flash Disk “&Label&”:\”&” est Environ de ” &DfreeMB,64,”Espace Libre”
WshShell.run “cmd /c fsutil file createnew “&Label&”:\IamDummy ” &Dfree&”",0,True
WshShell.Run “cmd /C attrib +h +s “&Label&”:\IamDummy”,0,TRUE

And This Code is used to delete The Fake Dummy File and so let you write into your pendrive.

Good idea, I have the same conern regarding malware, but on top of that I know some AV products consider some of my portable security applications to be a risk and delete them. Unfortunately this doesn’t solve the delete issue

Good tip. It is flawed, however, for large capacity drives (8GB or larger) with more than 4GB of free space. The reason? The FAT32 filesystem only supports files up to a few bytes less than 4GB. So if you have a 32GB flash drive with 20GB free, you would need to create multiple dummy files. Just a little annoying, but still entirely feasable.

I have a very strange request from client. I would be very thankfull if someone could help me out.

The scenario is: I have a server with some media file assigned to unique id’s and the server is conected to a series of USB flash drives port (20). Now, a user comes down & plugin his/her USB drive. Every USB drive has an .txt file, the .txt file names are nothing but the unique id’s which are already stored on server.

Once the user plugin he’s/her USB drive, the server should be able to read the .txt file name(unique id) and get all the media files from the server and copy it to USB flash drive. Once its done we shouls close the port.

Just to let you guys know, no monitor will be there and once we copy the files to USB it should intimate the User.

I know it sounds strange. Again any help / direction would be truly appreciated.

Thanks
Sagar
