True Image backup fails during having an other external hard disk on formating or with unallocated area

Thread needs solution

Hallo,

I had to format my first external 3TB USB hard disk, which need more than 30 hours. During this time I wants urgently to make an incremental image backup of my internal hard disk to a second 3TB USB hard disk containing already one full backup. True Image fails with operation "backup", could not make volume snapshot of volume 7, which is the in formating process used hard disk. So I wait with backup until formating was finished, tried again backup and again true image failed on volume 7, could not make volume snapshot.
I looked to computer administration -> data carrier administration and saw that windows 7 only formats 2048 GB of the 3000 GB hard disk and left an unallocated area. This unallocated area seems to be also a cause for true image not to operate a backup of my internal disk. Why can true image not make a backup in this case? How can I exclude "volume 7" from testing by true image during start of a backup?

Helmut,

If you are having problems with Acronis and the new 3TB drive and wish to try cleaning and converting the drive to GPT (allows full 3TB capacity on a single volume) to see if Acronis will get along with it better, follow the instructions below.

You can use the Windows command line utility "diskpart" to convert your 3TB disk to GPT, partition, format, and assign a drive letter to the partition.

Here's how: (Assuming you are running Windows 7)

Open an administrative command prompt by pressing the Windows Start button on your keyboard and type "CMD" without the quotes. At the top of the list, right-click on the first item (CMD or command prompt) and click "run as administrator.

A command prompt will open.

Type "diskpart" without the quotes and press enter:

You will now be at a "diskpart" command prompt.

(Do not type in any quotes symbols)

Type "list disk" and press enter

You will see a list of your disk drives with a number assigned to them.
Carefully determine which drive is your external 3TB drive that you wish to convert.
(You can open Disk Management to see the drive number assignments as a double check)

Once you have determined the correct disk number,

Type "select disk #" (replacing # with the correct number) and press enter.

To verify if you are using the correct number,

Type "detail disk" and press enter.

Carefully examine what you see to verify that you have selected the correct drive.
If not, start at "list disk" and select the correct drive using the above commands.

If you have selected the correct disk,

Type "clean" and press enter.
THIS WILL WIPE YOUR DRIVE. BE SURE TO SELECT THE CORRECT DRIVE FIRST!

After the cleaning is complete (only takes a moment),

Type "convert GPT" and press enter.
This will convert the drive to GPT and allow full use of the 3TB drive as one volume.

Type "create partition primary" and press enter.
This will create a single volume (partition) of 3TB on your drive.

Type "format fs=NTFS label=3TBUSB quick" and press enter. (You can change "3TBUSB" to a volume label of your choice)
This will format the 3TB volume (partition) and assign a drive label using the "quick" format method.
This should only take a few moments.

Type "assign" and press enter.
This will assign the next available drive letter to your volume (partition).
You can change it later in Windows Disk Management.

Type "exit" and press enter to exit the "diskpark" command prompt.

Type "exit" and press enter to exit the Windows command prompt.

Your drive should be ready to use as a single volume (partition) of 3TB.

Open Acronis and try your backup task again to see if you still have the same issues.

There is the True Image Extended Capacity Manager utility (from the utility option) which allows >2TB disks to be seen. This installes a filter driver, so has to be disabled if you ever uninstall 2013, programs that are not >2TB aware will no longer be able to access the disk correctly.

Thank you.

For formatting an 3 TB hard disk I could use successfully "EaseUS Partition Master 9.1.1 Home Edition" without making a GPT converting; so I could make a 3 TB MBR disk.

About the Acronis filter driver with "True Image Extended Capacity Manager utility": did I correct understand, if I uninstall TI and deactivate the filter driver, other programs, which could formerly access > 2TB, can access them after this not anymore? If this is not clear, I would not activate "Extended Capacity Manager utility". If I will activate, can than DD 11 Home also access > 2TB hard disks?

But the whole process war during formating of an 3 TB hard disk, so I have to wait until finished. During waiting for the end of formating, I starts a Acronis backup from internal disk to another external disk, but TI could not check the disk currently in formating process. So I want's to exclude a partition from checking by TI.

my operating system - windows 7 64-Bit - has no problems to access hard disk > 2 TB, True Image can also access hard disks > 2TB, also without Acronis Extended Capacity Manager. But DD 11 Home can not access hard disk > 2TB on my operating system, which can it. I think Acronis Extended Capacity Manager does not help for DD 11 Home, althoug Acronis says, DD supports advanced formating. But there are differences in advanced formated disks file system.

There is no way to preclude a partition or a disk from being scanned by True Image.
