Many newer Seagate retail products have more than one serialized product in the box. Therefore, the retail kit will have a unique serial number.
For example, the FreeAgent Go Flex USB 2.0 kits include a GoFlex Cartridge and a GoFlex USB 2.0 adapter. The drive module has a serial number and the USB 2.0 adapter has its own separate serial number. Since there are two serial numbers in the kit, the outside of the box has a separate serial number to identify the complete kit, a third serial number for the box/retail kit.
If you have a kit serial number and part number, you can cross-reference the drive module and cable serial numbers using the using the Warranty Look-up page.
Note: Starting in July 2010, kits have two serial numbers on the cardboard box.
Kit serial number: Represents the entire kit.
External Drive Assembly (EDA) serial number: Represents the serial number for the drive module, or EDA.
