Hi Experts,

Can you help?
I'm not sure about those:

1 - I guess simpler.
Need Delphi solution to know Device usb memory stick space left free total in bytes-hardware (Not Volume which is logical value dependable on formatting etc)

2 - Not sure
Wonder also if that is possible to check s/n number for usb dongle memory ( pendrive) with Delphi simply which will work on all Windows OS


Use new XE Delphi.

sorry again, confused so which solution is best?
here we can see:
http://www.experts-exchange.com/Programming/Languages/Pascal/Delphi/Q_28140731.html#a39203803

There we can see two methods:
http://stackoverflow.com/questions/4292395/how-to-get-manufacturer-serial-number-of-an-usb-flash-drive


Where author says: "UPDATE
Some drivers of the USB disks does not expose the manufacturer serial number on the Win32_DiskDrive.SerialNumber property, so on this cases you can extract the serial number from the PnPDeviceID property."

So which one is the best method which will work on all drives or maybe use two hybrid if one fail?

Would be good to have one solid solution which will just work is this from first link I posted or second method from stackoverflow link?

As you said - you can use hybrid method, bu I think that is second (on update) method better.
//note if you have multiple volumes on usb then your serial is: <serial>/<index of partition>
