On a computer that is running Windows Vista or Windows Server 2008, you use the built-in backup application to back up data to a removable USB cartridge disk drive. However, your removable USB cartridge disk drive is not recognized as an available backup destination. Depending on your operating system, you experience the following symptoms.
On a Windows Vista-based computer
If you use the Backup and Restore Center tool or the Back Status and Configuration tool on a Windows Vista-based computer, the removable USB cartridge disk drive does not appear in the On a hard disk, CD, or DVD list.
On a Windows Server 2008-based computer
If you use Windows Server Backup tool on a Windows Server 2008-based computer, the removable USB cartridge disk drive is mistakenly recognized as a DVD drive. You can continue the backup process by using the removable USB cartridge disk drive. However, some backup and restore functionality is restricted for DVD media. For example, you receive the following error message when you try to restore individual files or folders from removable media:
Recovery of individual files, folders or application data from DVD or removable media is not supported.
These symptoms occur even though the removable USB cartridge disk drive appears in Windows Explorer as a disk drive. This problem occurs only with some removable USB cartridge disk drives that are manufactured by certain vendors.
