Suddenly doesn't find (dynamic) disk

[Unjustly4413]

I finally found a backup solution that fits my needs. Many thanks for that.

I've been running it for a while, and suddenly - without any updates (as far as I remember) or changes to my system - one disk no longer appears in Hasleo. The existing backup task, which had been running daily without issues for a month, now throws the error: "Specified partition not found (0x1f650036000000e)." This error happens with automatic backup schedule, as well as when I manually start it.

When I try to edit or create a new backup, the partitions are listed exactly as they are numbered in Windows Disk Management, but the specific disk in question is just missing in Hasleo (disk 3, 7 disks in total). This happens to be my only dynamic disk, so it might be related to that.

The disk is still normally accessible in File Explorer. I have also performed a full reboot and checked the disk for errors. For testing purposes, it does how up in Veeam.
The problem came up with 5.2.2.3 which I was running for a month. I did update to 5.4.2.1, that didn't help.

This is even stranger: Despite my previous attempts and my current inability to manually create a backup, a successful backup did occur about two hours ago while we were in the process of resolving a forum issue. I did not reboot the system between my earlier failed attempt and that successful backup and now.

I checked logs but didn't see any useful information. Please tell me if you need any.

We have not made any changes to the code that supports dynamic disks, and Microsoft seems to have abandoned dynamic disks in favor of storage pools. To further analyze the issues, please click "" > "Save log file" to open the save log file dialog, save the log file and then send it to us via email at [email protected]. Thanks.

It's working fine with my Raid 1 Dynamic disks btw

I want to add, while it's a dynamic disk, it's not in a raid or mirror.
I sent the logs as requested.

How many partitions were originally selected for backup by this backup task? The log file does indicate that there are partitions that were not found, are you sure that all the partitions originally selected for backup still exist? We can't find out much more from the log file as the earlier log records no longer exist. Perhaps you should recreate the backup task and contact us as soon as the issue occurs again.

1 partition was selected. Yes, 100% that partition does still exist. The dynamic disk has 2 partitions, but the whole disk does not show up in Hasleo. It does tho in Windows Disk Management as well as in Veeam. I can't recreate the backup task when the disk/partition does not show up (same goes for edit the task).

I want to note again, that there was never a issue accessing the disk or partition at anytime or with any program. It's unchanged in the system for years. Because my most personal data is on it, I would have noticed if at any point there was a problem with it. It also got a backup daily for years (Macrium, Veeam).

Are you sure the dynamic volume is still accessible? We analyzed the log file again and your dynamic volume appears to be on disk 3, specifically the third partition of disk 3, but Hasleo Backup Suite gets 0x15 (The device is not ready. ) error when trying to access the volume, the volume does not seem to be accessible.

Yes, I'm absolutely sure the disk is accessible at all times; it has never been inaccessible.

Today, it randomly created a backup successfully, yet Disk 3 still doesn't appear when I open the app to create or edit a task (no reboot occurred in between).

I don't know why it wants to access the third partition:

DISKPART> select disk 3

Disk 3 is now the selected disk.

DISKPART> list partition

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Dynamic Data 2794 GB 17 KB
Partition 2 Dynamic Reserved 1024 KB 2794 GB
Partition 3 Reserved 127 MB 2794 GB

Can you send us the latest log file? Maybe we can find more clues. Thanks.
