I have Windows 7 Ultimate running on a Toshiba U305 laptop, Bios Ver 3.9. I am running out of disc space on the 80 GB Fujitsu SATA hard drive and tried using Windows 7 built in drive cloning. When I go to create a system image and specify my Hitachi 250 GB SATA drive which is running externally on a SATA to USB adaptor, I get a message that the backup will take up 68 GB on the new drive. When I proceed to create a system image, I get an error message "The backup failed. There is not enough disk space to create the volume shadow copy on the storage location....... (0x80780119)" Windows shows that I have 12.5 GB free on the old drive and the full 231 GB free on the new drive. I reformatted the new drive just to be sure. I can read and write to the new drive. Any ideas?

Hi, Firstly, Windows 7 has a 100MB system partition that Windows setup during the installation that was under capacity, but not every computer has the 100M on their computer. Now, I suggest checking the disk usage in disk management carefully and make sure all the partitions have enough space to do system backup image: Click Start->Right Click on Computer->Choose Manage->Expand Storage->Click on Disk Management You can see the clearly of the usage of the whole hard drive. Please check it carefully and make sure all partitions have enough space. Notice: if you have some hidden partition on the computer, please also make sure the hidden partition has the enough rest space to do the system image on the computer. If you only have one partition to save the system files on the computer, maybe there will be a problem of backup system image. At this time, we can shrink a partition in disk management, and then do a system backup again to test this issue. If the issue persists, please check the hard disk for errors. Also, this error may be caused by the system image backup configuration on the computer or some related components or services or registry incorrect on the computer, you can follow the below steps to check it firstly: 1. Run “vssadmin list writers” to check if there is any error. 2. Register related dll files (we can ignore error messages if there is any) cd /d %windir%\system32 Net stop vss Net stop swprv regsvr32 ole32.dll regsvr32 vss_ps.dll regsvr32 es.dll regsvr32 stdprov.dll regsvr32 msxml3.dll regsvr32 msxml.dll regsvr32 msxml4.dll 3. Stop related services a) Volume Shadow Copy Service. b) Microsoft Software Shadow Copy Provider. c) COM+ event system d) COM+ System Application 4. Under HKEY_LOCAL_MACHINE \Software\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscript, delete the "Subscriptions" key and leave the EventClasses key 5. Under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VolSnap add MinDiffAreaFileSize (DWORD) and set the value to 3000 6. Restart above services 7. Restart to check the issue After that, you can follow the below detail instructions to set the configuration and do a system image backup again: How to Create a System Image Backup in Windows 7 In addition, you can try to back up the whole system image on the local disk to test this issue, please don’t backup the system image on the external hard drive or DVD directly. If you can back up the whole system image on the local disk, we can copy the system image to your external hard disk or DVD.
