Hi
I have upgraded this customer PC to windows10 22H2 today.
However one upgrade is missing when checking for upgrades - KB5034441. This upgrade fails constantly with error 0x80070643.
Scenario:...

Thanks Bree for pointing out - calculation has been corrected.
But main issue is still open: Are there any real alternatives for macrium reflect?

Hi
ad pricing for reflect home: I have documented the 100% increase in original post.
ad Hasleo backup: I have no experience with this company and their support, may be it is worth trying

OK, as said I need support out of US or Europe, chinese support I have already tried, it does not work.

Hi
I have been using Macrium reflect happily for myself and my customers for last 3-4 years.
I switched away from Easeus to do backup, due to hopeless customer support and the fast that their...

Update 240118:
Even though I still do not know the root cause for this issue, it seems that rescheduling online backup to a less busy timeslot can be used as a WA. This is in line with this article...

Thanks, that was exactly the type of info I was looking for. So I will check event log again, I was searching for 0x15 in vain.

The whole reason for raising issue in this forum is that macrium support and forum say that error is just passed on from windows.
But so far they have not been able to tell me where to look for this...

yes I know.
But that is not my question.
I know exactly when error 21 was coming from macrium full backup log.
Now I just want to see where in windows I see this error - so far I did not find it...

Well before performing any action I want to check where this error is generated.
So where should I look to see this 0x15 device not ready error?

Hi
I was dialing in to customer PC 19.12 since another incident of full backup failing with error 21 happened 12.12.
I was checking event log via event viewer for error 0x15 – device not ready, but...

Thanks Bree, I will follow your advice to check all 3 partitions on this SSD, not only C:.
Btw. how to check the first one SYSTEM_DRV?

Thanks.
I already checked what you mention before raising this case about intermittent failing macrium online backup.
Obviously offline backup works fine, that's not the issue.
As far as I see...

Hi Dalchina
Thanks for response.
I am using a licensed version of macrium.
The reason I raise this case here is that both macrium forum as well as macrium support tell me that this macrium error...

Hi
During macrium online backup I am getting error “Backup aborted! - Unable to read from disk - Error Code 21 - The device is not ready”.
Macrium says that they are getting “Error Code 21 - The...

As suggested by Megahertz I made in-place upgrade and that solved the issue.
I.e. PC upgraded to 22H2, still we don't know why upgrade from 21H1 failed.

sure, I can try that - just wonder why windows update does not work in this case for 21h1

Thanks, I will check the articles you mention.
For sure I have not decided 21H1, I have not been using this laptop for some time and now I want to get it it up to date - so far no luck.

Hi
On my Lenovo X200 x64 based PC with windows10 21H1 windows update just flashes with KB5001716 and then gives error 0x80070643. No 3. Party AV, only defender.

I have tried suggestions as...
