All data on the disk could be erased if you attempt to change the drive's partition type from GPT to MBR, so you should make sure that you have a copy of all your data on another drive prior to changing it. But at least now there is a chance that the data on your new external drive will be able to be correctly detected and read by your TV. Now, no matter how you slice it, this space is being wasted. This is far from an ideal solution because it means that only up to 2TB of space will be usable on a 3TB or 4TB hard drive. The solution is a harsh and time-consuming one: you'll have to re-partition the drive so that it uses an MBR (Master Boot Record) partition instead. We recently found this out when we plugged in a 3TB WD Elements ( Amazon) hard drive into a 32-inch Samsung LA32C450E1D LCD TV and found it couldn’t be read. What's more, if you plug a GPT-based drive into a TV, it might show up as being recognised by the TV, but it will not be able to display any of the information that you may have previously put onto it. It's one of those things that's very dependent on the brand and model involved. However, this very same partitioning format may not be recognised by your TV. GPT allows the entire capacity of the drive to be usable on a computer system. Regardless of their size, many new external hard and SSD drives usually rely on a partitioning format called GUID Partition Table (GPT).
