Regards,

Sorry, I have looked into this a bit and I can’t narrow down why it stops working. Ususally the “untracked write” errors occur because the partition size has changed. But then it should work at least if you remove + add it again…

Can you think of seomthing that changed when or before it stopped working?

Yes changed size of partition. I have tried uninstall client reboot delete c:\programfiles\urbackup\ install client reboot.
Nothing change, still is not works.

How much did the volume change? How did you change the size? The write fails at offset 3132350464 . Is that within the new volume size?

Further places to uninstall is deleting the file C:\System Volume Information\urbct.dat. But you need to be sure the driver is not running anymore (sc query urbackupcbt)!
Also perhaps take a look at the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\STORAGE\Volume with UpperFilters urbackupcbt and the Device Parameters of the same.

I installed new disk (ISCSI) then copied (data from old disk to new) and then change drive leter.

I cannot stop urbackupcbt drivers.

C:\Windows\system32>sc query urbackupcbt

C:\Windows\system32>sc stop urbackupcbt
[SC] ControlService FAILED 1052:

After uninstalling urbackupclient, driver urbackupcbt still running too.

I haven’t tested it with iSCSI… that is probably why it is not working.

It’d need a reboot.

It worked before changing volume.
Another ISCSI (I,G) drive works fine

How to uninstall and install everything as if I was installing for the first time?

I have rebooted and driver still running. Urbackupclient is uninstalled.

What is supposed to be same?
