Error: target drive is mounted read only

Hello, I am trying to backup my Windows 10 PC with rescuezilla. I have 2 internal SATA hard drives. Both nfts formatted. I want to backup C: to D:. But I always get the message that the destination drive D: is mounted "read only". So I can not create a backup. I can backup to a USB stick or an external USB drive without any problems. Only to the 2 internal SATA hard drive not. But why?
Thanks
Walter
Hi Walter,
Most likely your destination NTFS filesystem may be hibernated.
One easy way to test this idea is to try selecting the 'Restart' item from the Windows shutdown menu, rather than 'Shutdown'. Then immediately boot into the Rescuezilla USB stick.
It's possible to disable hibernate entirely from Windows, but that's obviously not ideal.
Some reading may be interested that hibernated Windows source disks can actually cause an error when Rescuezilla v2.1.3 (and earlier) try to make a backup, but I have implemented a solution to that particular problem for Rescuezilla v2.2 (to be released late-May 2021, in other words: next week).
Thank you for your reply.
It is indeed due to the hibernation mode. If I reboot as you suggested and then start Rescuezilla, I don't get the "read only" error message. You can also disable hibernate in Windows.
Until now I use Acronis True Image and I don't have this problem. I am looking for an alternative to True Image, but the limitation described here keeps me from switching to Rescuezilla. Otherwise I find Rescuezilla very good.

Same problem here harddisk read only mode due to hibernation.
I still get the hibernation message when i reboot or shutdown and then boot
Hi. I've run into this too, restart seems get things going nicely. My question is, will this also come into play during recovery? If for some reason I can't boot to windows and therefore can't restart, will my main drive be mounted in read only and I wont be able to restore to it? Main drive is M.2 if that makes a difference.
TIA
The hibernation thing doesn't come into play during a restore (which overwrites the target partition), because the restore process completely overwrites the target partition, whether or not it was hibernated.
In other words, if the backup image was made successfully (displayed no errors) because the NTFS filesystem was not hibernated then your restore is expected to work fine.
I had the same problem but i found a solution:
open command window in administrator mode and write:
powercfg.exe /hibernate off
and restart system from rescuezilla that now can work correctly
after , when u start window again u can restare the system hibernation writing:
powercfg.exe /hibernate on
I hope this can solve problems
