So I just got a brand new computer. The hard drive is a Sea Gate Barracuda with 3TB on it. I wanted to shrink it to transfer it over to the C:/ drive. After doing so, there was no allocated space. I just went from 3TB to 700GB. Somehow it dissapeared. I've spent the whole night looking at forums and googling this but no luck. I have tried disk management, command promt, partition wizard, Dos System files to check the Bio, Hdat2... Pretty much everything but now it's a 30GB and it's worse with me trying tto get it back. Please help me, I'm on Windows 8

What are you saying? It is not clear to me. You got a new system. It has a 3TB HDD Is it correct that when you got the system, it had the OS and some other things on the new 3TB drive. Are you saying the 3TB drive was full (hard to believe). What did you want to transfer? Was it from your old system? What did you do when you say you shrunk it? You need to go step by step and list what you did please.

Alright I'll be more clear my apology. So I have my Os loaded on drive C:/ and then a second internal HDD on D:/ That is the 3TB. I had some files on it and I wanted to shrink it to create a new partition. I was expecting unallocated space after the shrinking but there was nothing. It became about 700GB left of 3TB (that's how much I shrunk). I used all these softwares and tools to try to get it back and I read forums and nothing worked. My 700GB went to 30Gb after I tried formatting it. I have no clue whatsoever on how to reach full capacity again.

okay so now i just gained 75GB of extra capacity. I used HDAT2 and used the Set Max Address solution and tried to remove the HPA and this brought it back up. It didnt work earlier but for some reason it does now? Any suggestions on how to keep this up to my max 3TB?

You will never get full capacity. It sounds like you have it fixed. Nice going. FYI all the disc management software does not work the same. You were lucky this time. In general it is not a god idea to shrink things. If you need more space get bigger or multiple disks. If you ever have to do a system or data restore having a shrunken partition can be a nightmare.
