The reason I asked for the actual output from the command was to verify the formatting of the information to see that UD is parsing and dealing with the output properly. There are several steps involved in gathering the information, and storing it for display to the UI. I was looking to start from the beginning to see if I can find where the problem occurs. The next step would be to see if it is being acquired and properly stored before UD displays it on the UI.
There were some changes made in the last few months to not constantly query disks for information to display on the UI to keep from hammering the disks with IO. Some information like size, useage, and free is collected at timed intervals rather than each time the UI is refreshed.
This is the first time this has come up, so I assume it is something unique with your system or disks. Your presumption that UD is not calculating the information correctly is not helpful in coming up with a solution in your case.
I didn't ask for the output just to prove that the disk information was correct. I assume it is.
Since you do not care to share with me information I ask for so I can help with your issue, there is really nothing I can do to help you.
Note: I am a volunteer like most people here providing support on the forum. I have limited time to devote to helping users like yourself. I will do what I can, but your argumentative attitude doesn't inspire me much to help you.
