[SOLVED] 3TB HDD only showing up as 349 GB?

[id6016]

I recently installed a 3 TB HDD in to my computer and windows only recognizes it as 349 GB.

I am assuming you have another 3TB also ?
What does it show in disk management?

I managed to increase it to 2 TB

Have you tried reformatting the drive to a partition?
Was this taken from an external enclosure?

What MB do you have?

3. I dont know exactly what mobo it is, but i know that its made by the republic of gamers and has an LGA1151 socket

download and install
Hard Disk Sentinel - see if there are any errors on it.
That may be an issue.

I've seen reports that Seagate external HDD have to be reformated before being used internally.

I think I got it, for some reason it wont allow me to make it one 2.7 TB HDD, so its one 2TB and one 700GB HDD

That will likely be down to an MBR limitation - as it will only allow up to 2.2TB.
GPT can allow higher - If you can format it as GPT, it should allow higher.

The USB-SATA bridge firmware in Seagate's external drives is configured for a sector size of 4KB. When you remove the HDD from such an enclosure and attach it to a SATA port in your computer, you expose the drive's native 512e sectoring. This renders your data inaccessible. The reported capacity also changes by a factor of 8 (= 4096 / 512).

So 3TB / 8 = 349.2 GiB
