Computer does not see 5tb drive in windows

[Computerdo]

I am using an Asrock z77 extreme 4 motherboard and it does not see my 5tb hard drive in windows. its visible under as a bootable drive but that is the only time it shows up. The motherboard is most likely the problem because it might be able to recognize a 5tb drive.

Is it listed in Disk management?

Its not visible in disk management or in the explorer. i can my two other drives in disk management through

Try installing the Unlock utility: link

actually it is visable under disk management but its split into two partitions. could you tell how to make it one partition?

 

[alexoiu]

Try converting it to GPT.

ok so I formatted one of the partitions but the second one is marked as unallocated and i cant do anything to it. how do I format it so I cant see it in a partition manager.

Try installing the utility in my previous post.

A FORMAT operation will not change the way the PARTITIONS on a HDD are set up. If your HDD has two partitions and / or some Unallocated Space AND you do NOT have anything on it you want to save, you can proceed as below. HOWEVER, if there is any data you want on that drive, BACK IT UP to another storage place before proceeding.

Now, I'm going to assume you are using Win 7 or 8 that knows how to deal with HDD's over 2 GB and GPT Partitioning.

Go into Disk Management to the 5 TB unit, probably in the lower right pane. For each block that represents a Partition, RIGHT-click on it and choose to Delete it. Do this until the whole HDD is one piece of Unallocated Space. Now, RIGHT-click on that and choose to Create a New Simple Volume but WATCH carefully. Choose the option to make a GPT Partition and let it use up all the space available for this. The new Partition does NOT need to be bootable (assuming you're only using it for data, and not for booting). When you have the options set correctly let it go to work. This might take a LOOONNNGG time, so just let it run and be patient. When it is finished, back out of Disk Management and reboot so Windows updates its Registry properly. Now that unit should show up in Explorer as a drive of about 4.6 TB.

under disk management I see two parts of the 5tb drive booth unallocated but for some reason I cant do anything to the second unallocated. I am stuck with two parts of the drive and I cant do anything to the second part of it.

Have you installed the utility?

 

[Computerdo]

Yeah, but even after I used the 3tb+ unlocker it still doesn't work. Maybe there something I haft to do in the bios after I installed the utility.

Try using diskpart for clearing the drive and converting it to gpt.
