I have now made an extra attempt. My previous restore was a test one. Now I want to retire the old disk, transfer data to the new one, and stop writing to the old disk.
So I tried to make a new image + restore, the last one. Image failed,as it has been doing so often for, I think, years now.
I'm all the more worried since I did that from the Rescue environment (booting from the special Macrium partition), in order to avoid possible VSS problems. Well, it failed, as has been so often the case lately, when I try to do a full as opposed to differentials or incrementals (but those fail, too).
The error message was one I often get :
Backup aborted! - Unable to read from disk - Error Code 1117 - The request could not be performed because of an I/O device error.
But they vary. I get all sorts.
So I tried to clone instead, and it worked. However, it worked too well. It completed in 8 minutes. For 154 GB of data. (And I did not tick the box Ignore Bad Sectors.) Whereas when I cloned my system disk, it took 3 hours and 22 minutes for 148 GB.
So two questions here :
- Can that really be the result of Rapid Delta Clone ? My data was already on the target disk, and the differences were likely very small. Does not Macrium verify the result of its work, when cloning ? Just the verifying phase takes a lot of time when imaging.
- Can any hints can be taken from this to troubleshoot my endless imaging failures ? Cloning a disk worked twice (admittedly, this is not very much). This happens inside the computer. Imaging fails very often, in multiple software and hardware situations, but the common point is it happens whith target disks outside of the computer. It happens with incrementals, differentials and fulls (especially with fulls), and it happens with an USB 2 cable, 2 different USB 3 cables and an eSATA cable. It also happens with different disk enclosures (2 different models, and 2 pieces of the same model). The target disks themselves are the same model (there are 2 of them).
