Specs: windows 7, FX-8350 / 8 GB
Hello everybody,
The problem l have is, that l have a Hitachi HDS5C3030BLE USB 3TB external drive, l am trying to reformat the whole drive, so that it is one drive, instead of partitioned into 3 (as it was). l went into the control panel, then Administrative Tools, then Computer Management, then Storage, then Disk Management I combined the first 2 partitions of the Hitachi drive into 1, but when l tried to combine the 3 partition into the other parition, it wont. So the situation is, l have a 3TB hd, which has only 2TB is visible in my computer, but in disk management, it shows ;

Disk 3
Removable (L:)
2794.52 GB 2048.00 GB 746.52 GB
Online Healthy (Primary Partition) Unallocated

If only all computers were easy it fix or never went wrong, we'd never have forums to help

If you don't need any data that's currently on the drive, delete all three partitions (right-click each one in turn & choose "Delete".

Then create a "new simple volume" on the unallocated space (right-click) and accept the default volume size.

You'll then have just one big partition filling the entire drive. Now format it so you can write new data to it.

Hi Phil22,
as l said the first 2 partitions are merged as 1, but l cant merge the 3rd partiton to merge with other partition. When l right click on the 3rd partition, new simpile volume, new spanned volume, new striped volume are grayed out and only leave Properties and help. l cant do anything with the partition, not even format it or delete.

✔ Best Answer
You should be able to delete it once you delete the first partition. The drive may be partitioned using MBR but the larger drives need to be partitioned with GPT in order to be able to use a single large partition. The drive you have may have been partitioned with MBR that was modified to handle the larger drive in parts. Deleting all of the partitions should let you repartition using GPT which will let you do what you want. If there is any data on the drive, move it to another drive and verify that it is accessible before deleting the partitions.

You have to be a little bit crazy to keep you from going insane.

The total size of a 3TB HDD is approx 2794GB. You show the HDD as 2048 GB (primary) + 746.52GB (unallocated space). You'll have to convert the unallocated space into a partition, format it, THEN combine it with the other partition. If you can't do it from disk management, try EaseUS Partition Master:

Hi Riider,
l have deleted the 2048GB partition, so that it is unallocated, and the other partition is already unallocated. l then l created a new partitrion as the 1st partition, but it only lets me creat upto the same size (2048gb or smaller) for the 1st partition (it shows as 2746.32gb as 1 unallocated dive, but will only let you create a drive of 2048gb and still leaving the second unallocated partition), you can see the smaller 2nd partition next to it, but cannot merge the 2 partitions. l am using the free EaseUS Partition Master. when l try to merge the 2, all it says when right click on the 2nd partition is, wipe data and veiw properties

Hi Fingers,
You said that, the drive may be partitioned using MBR but the larger drives need to be partitioned with GPT in order to be able to use a single large partition. l dont know how to find that, lm just using EaseUS Partition Master. maybe this is stopping it from merging the other partition ? l dont know

Thank you for all your help, much appreciated. It was the changing from MBR to GPT that was the problem, as soon as l changed the merging for the 2 partitions, again thank you for your help
