Hard Disk Monitoring

HDS 6.10 fails to update the 'Disk Performance' tab when more than 1 partition exists.
I observed this behaviour when I attached disks from a windows installation,
then my pc gives letters to 'System Reserved' and main partition.

Several disks resulted in the same behaviour.

I am using Windows 10 Pro 22H2 build 19045.3513

Thanks for your message. Sorry for the troubles, but I can confirm that the number of partitions surely never cause troubles with the "Disk Performance" tab: the partition(s) on the drive are completely independent from the real-time performance monitoring. It is not relevant if the drive has 1 or more partitions.

If you encounter problems with the performance monitoring, then probably the Windows performance counter objects damaged.
This is fortunately more rare these days (was more common with older Windows versions) and the

page explains the situation, gives details about what to check, which commands can be useful to repair / enable the performance monitoring in general.

In addition, I suggest to use Report menu -> Send test report to developer option, as then it is possible to check the actual situation, it may give some ideas, thoughts about what happens and if there is anything to do.
