IBM Lenovo M90p, 2TB HDD limit ?

Just plugged in a Seagate 3tb HDD directly into the motherboard SATA jack and Win7 can only recognize 2tb, nothing over that. The BIOS is one level down but the current level is for security only so that does not appear to resolve this issue. Not sure what the resolution is on this. Any help would be appreciated. Thanks

Setting the drive up for GPT allows for all available space to be formatted and used. Thanks for the suggestion.

Thanks for the links and yes I did read them. The third one, “how to break the limit” was very helpful with all of the background info.  I disagree with your comment that by initializing the HDD as GPT “it is not correct” and here is why.
1)      This is NOT my boot drive on my Win7-64 operating system.
2)      This is not a “convert” operation, there is no data on the spare HDD to begin with.
3)      My motherboard does not have EFI BIOS so I now know that I will always be booting from an MBR drive C, which is fine in my situation .
Again, thanks for the links as they clearly explain why I now have a 3TB GPT drive and all of the storage space is available.

i never said GPT was not correct  -mbr i used
i know that turning it into GPT is the solution

i only posted the objection for future readers - it is VERY misleading imo

If future readers read the link you provided....

how to break the limit :  http://carltonbale.com/how-to-break-the-2tb-2-terabyte-file-system-limit/

I am sure they will understand how to get past the 2TB limit.

Thanks again, now lets move on please.

Nobus are you saying MBR doesnt have a 2.2 TB limitation? I disagree. My statement is correct sorry..

"The problem in this computation is that the partitioning scheme that is used by most modern Windows-based computers is MBR (master boot record). This scheme sets a limit of 32 for the number of bits that are available to represent the number of logical sectors.

The 2-TB barrier is the result of this 32-bit limitation. Because the maximum number that can be represented by using 32-bits is 4,294,967,295, this translates to 2.199 TB of capacity by using 512-byte sectors (approximately 2.2 TB). Therefore, a capacity beyond 2.2 TB is not addressable by using the MBR partitioning scheme."
