Requesting help in your inbox not make sense lol.

Actually when you are talking about hardware stuff, Java is not a good solution at all. JNI is the best, VBScript or a C/C++ dll can use for that. Search for such things on the web.

i want platform independent language..so i have choosen java..

[Eranga]

Ya it's true. But that's not easy as you expect. Did you search on the web? How many articles you find about this?

[manucng]

i dint find relevant article,,,but i need this..

[Eranga]

Did you find this one.

Get the hard disk serial number or Processor/Cpu ID - Real's Java How-to

[manucng]

yeah ,i tried this ..its not working properly..i guess i have to add something to this code...

[Eranga]

Okay, so let us know what comes across with. I mean did you get any error messages there? If so show the complete error message here to see.

[manucng]

No i dint get error message..but i dint get serial number...
its displaying some 6 to 7 digits number..but nt serial number...

[Eranga]

Are you tried the example I've send in previous link. It gives me the correct value actually.

[manucng]

yeah i tried the same..instead of C drive..i have passed F which is my USB drive.its not retriving serial number of my usb.

[Eranga]

Actually I've forget the original question lol. Using this scripts directly we cannot deal with external drivers. If you have time please look-at the following project, I found it by a google search.

JSR080 - javax.usb
