Acronis 2019

Thread needs solution

I have 3 external drives that when using Acronis 2019, changes the drive letters or prevents one from being recognised on bootup.

I have another backup program that I have been using for approximately the last 6 months with no problem.

I have purchased a new computer and started using Acronis again to see if problem  exists, but yes it still causes

problems with the external drives.

Does anyone have similar problems or a cure for this?

When you say "when using Acronis 2019" do you mean

  1. the drive letters changed when you installed ATI
  2. the drive letters suddenly changed when you opened the ATI GUI
  3. the drive letters are different in an ATI recovery medium than under Windows?

#3 is to be expected.  The various recovery media do always map the drives the same as Windows.  I don't think there is anything that can change that.

I've never heard of #2 happening and can't think of how it could happen.

Installing ATI should not change the way Windows maps your drives, but attaching, detaching, or mounting a drive around the time you installed it could do that. 

Joseph, ditto to the questions from Patrick above, I do not understand your statement:

I have 3 external drives that when using Acronis 2019, changes the drive letters or prevents one from being recognised on bootup.

Drive letters are allocated by Windows Disk Management and are not changed by running ATI 2019 (or any other application without some form of user intervention or interaction).

What exactly are you seeing happen here?

This happens when boot up. I don't require to open Acronis to create the problem.

Having booted up just now, one drive on my desktop shows a question mark against it. I have to switch it of and back on to get it to be recognised

If I uninstall Acronis & use Todo backup I have no problem.

Joseph, thank you for the further information but again I have not seen any other reports of such behaviour in these forums, nor experienced anything similar myself.

Does this behaviour still show with ATI just installed but with no backup tasks created?

Note: I would recommend running the Acronis Cleanup Tool before reinstalling ATI 2019 to ensure that there is no residual data from when it was installed previously.  There should be no need to follow the steps to change any Windows Registry settings!  A link to the tool is in my signature.

What color is the question mark?  A blue question mark is Windows' way of saying that the drive pointed to by a shortcut cannot be found.  There is also a red question mark (which I sometimes get for a mapped NAS drive ... even when the drive is reachable); I don't know what it means.

It sounds like ATI is keeping Windows from finding your drive in a timely fashion.  I've never seen that happen, but it makes more sense than ATI changing the drive letters.  Is there anything in the Windows Event log indicating a problem?

When you switched from your previous backup software to ATI did you leave the  old software installed?  I wonder if ATI initialization and the other software's initialization interact in some unwelcome fashion.
