brand new 3tb seagate HDD, installed win7 on it. windows will randomly freeze up after a few hours, then reboots. when it starts back up I have a black screen with text, it's 2nd screen one after my bios boots (one you'd see "press any key to boot from disk") and it says NTLDR is missing press ctrl alt delete to reboot, well i warm reboot (Ctrl+Alt+Del) and go into my BIOS and it no longer shows my SATA connected HDD, but just ((HARD DRIVE)) in my boot sequence, so it seems my HDD is disconnecting from my PC or my pc wants to stop recognizing it, BUT after i just do a reset by holding down the power button, windows boots up just fine and that HDD is picked up just fine. problem is it's reoccuring and usually this stuff just gets worse..
My question is, is there a program i can run to verify my HDD is the issue?
Also - I'll need to reformat because i've learned that you have to format out of MBR format for the full 3 TB to be picked up by win7, otherwise it just shows 2TB. Any luck that may resolve my issues? And also if anyone has a walkthrough on what i need to do that would be great (still not sure of what format it needs to be and if my motherboard will play nice with that format)
