I recently purchased a new 2Tb seagate hard drive and installed it myself and for some reason it will not show up so that i can use it. I had 2 seperate 1TB drives installed previously and i am not sure how they are set up, the person that build my computer set them up in some kind of raid or something . I played around with a few things in the intel matrix storage console but i don't really know what im doing. I have provided a few screenshots so that may help in understanding what is going on. If you need anymore just let me know.
He put the two drives in and partitioned the first drive with the OS (C drive) at 100Gb and an 831Gb partition (D drive). The second physical drive is a single partition for the whole drive (H drive) at 931Gb.
i would like to know how to get the drive in a single partion like the H drive, and no there is nothing below the cd drives in disk management. what part of the bios does it show up in? it shows up when i boot the system as a 1.8TB drive.
The H drive still shows up in disk management as 931 Gb and no i didn't remove it. no i was trying to make the drive show up in disk management by doing something in intel matrix storage console and now the disk is migrating but im unsure what one and what migrating is?
Since the first disk (disk 0) has somehow appended the new drive on, only half of the new drive will show up because the smaller of the drives dictates the size. The unallocated space cannot be more than the drive size that it was arrayed with.
I still have no idea how that was set up without explicit instruction given to create the array, although like you said, you were playing around with the Intel manager. Unlike before you added the 2Tb drive -- now your first drive is in RAID 0 with half of the 2Tb drive, the other half being unusable as now configured.
I would do a clean re-installation with only the OS drive attached. Then attach the other two storage drives and don't install any RAID drivers, select AHCI sata mode in the bios before the new installation. You will not have that issue again.
I would move all the data off the H drive, then do a simple format, copy all data back onto the H drive. Then remove all the drives except C. Change your bios to AHCI sata mode instead of RAID and then startup with the Windows 7 installer disk in the DVD drive. Select custom install, delete and unpartition all partitions. Then just allow Windows 7 to install. Then you can re-attach the other drives. Don't put any Intel RAID drivers back on the machine.
To insure that it is not involved in the RAID drive issue -- you can try it without formatting that drive as it may not be. I just don't want you to be in the situation of trying to get all your files back off of H and have an issue that it is inaccessible after the other drives are reformatted, might not be a problem but I can't be sure without sitting down with your system.
