For example, you can list the removable drives:

C#

using System.IO;

//...

DriveInfo[] drives = DriveInfo.GetDrives();

foreach (DriveInfo drive in drives) {
    if (drive.DriveType == DriveType.Removable)
         // do something...
}

Or, with LINQ:

C#

using System.IO;
using System.Linq;

DriveInfo[] removableDrives =
    DriveInfo.GetDrives().Where(drive => drive.DriveType == DriveType.Removable).ToArray();

To best of my knowledge, there is no a way to tell the flash drive from other removable drive. In a way, this is not really needed. In practice, you only may need to check if the access is read-only or you may to make sure the drive is not the system drive of a currently running OS (because you can always boot from a removable drive).

It would be a completely different story if you wanted to handle the event when the removable drive is inserted. This is the way you can do it with USB removable storage:

http://stackoverflow.com/questions/271238/how-do-i-detect-when-a-removable-disk-is-inserted-using-c[^].

Unfortunately, this does not exhaust all possibilities. For example, the removable storage could be motherboard-integrated, which is often the case with SD/SDHC/SDXC drives. Such events are detected, but unfortunately, I don't know how to do it, at the moment.
