Hey guys - first time posting here as I didn't see this covered.
MC x64 15.6 (3119)
WIN10 x64 24H2 | 16GB
I found https://forum.multicommander.com/forum/index.php/topic,4999.msg14770.html#msg14770 (https://forum.multicommander.com/forum/index.php/topic,4999.msg14770.html#msg14770) related to MC not starting due to Veracrypt volumes.
In the most recent version, I am having a similar problem, with the exception that in my case MC does start, but it now takes twice as long as before.
I have internal HDD Veracrypt volumes which still load just fine and the mapped drives show up in MC as normal.
However, Veracrypt volumes on external drive (USB-C) and which show up in WIN just fine, are no longer shown in MC.
In MC, I can however use the Command Line Bar to display the drive contents by using it's path e.g. Y:\
If there is no external VC drive connected, MC starts up as normal, and the drive is displayed as normal.
I looked through the log file through repeated runs, but didn't notice anything related to this - other than the increased startup time - which used to be almost instantaneous. I also noticed some anomalous entries related to cloud (Google, Microsoft, Dropbox) drives, though I will probably write that up as a separate issue.
ps. I am a dev; so I can help with debugging this if needed.

Upon further investigation, I found that disabling (untick all 3 trees) "Override default settings" in Configuration->Explorer Panel Settings->Device Filtering, then closing and restarting MC, appears to fix this. The external Veracrypt drives then show up in the drive bar (icons) as well as in the drop-down drives list.
-
If it gets a device letter it should just work. There is nothing special with Vera that MC sees.. (I use it myself)
Everything in device filter should be off already by default. It is used so you can tweak the and override some default behaviours, So you must have enabled something there that would have filter it out. And when you turned it off it got back
But good that you got it working.
-
Indeed. I only thought to look in device filtering because it was the only setting that would have made sense for controlling device display behavior.
However, as you said, "if it gets a device letter it should work", I can't imagine why only VC devices would be affected by this device filtering setting. Why are other drives unaffected?
And I just tested it again. With those settings enabled, the VC device icons disappear. And the standard drives remain unaffected regardless of that device filtering setting.
As a dev myself, it's the sort of puzzle that I would take a closer look at because, if standard devices are displayed - regardless of device filtering setting - then VC devices shouldn't be affected either.
-
It depends what is check under the device filtering section. Might be that Removable harddrive is unchecked.
-
I had checked all 4 sections in Device Filtering to figure out what the issue was. Which is why I wrote up this report.
Also, I have both internal HDD encrypted volumes as well as external SSD encrypted volumes.
If it's any help to you, I am using VC 1.26.24 x64
-
Yes But if you expand them. there are individual options under each section.. on what devices should be shown for each UI place to show devices..
Some of the option for the place where you did not see the device was probably not checked.
I don't think VC version matter.. MC does not see it as a VC device. it just see a removable harddrive. it does not know if it is VC or not. all that is handled in kernel level in Windows

Yup - I am aware. That's why it's the first place that I checked when I was trying to reproduce this issue. I have all of them checked - except "Floppy" (which appears to be unchecked by default)
