CheckUsbHdd

[KozakMak]

CheckUsbHdd=1 Check whether a harddisk is connected via USB (uses removable disk icon)

If default value is 1 - why i don't see any "removable disk icon" ?

There's two possible reasons:

• TC has added CheckUsbHdd=0 to the wincmd.ini, which it does automatically if and when USB devices take longer than expected to react. This setting stays in the wincmd.ini until removed manually, and is added again when the next drive reacts slowly.
• Your USB device is not recognized as removable by the system. That is the case for one of my flash drives (JetFlash 920, 128 GB). You can check whether or not the drive's context menu lists an "Eject" item - if it doesn't, then it's not a removable drive to the system (and thus TC doesn't list it with the removable disk icon).

1) there is no string CheckUsbHdd in my wincmd.ini
2) i have in sys.tray safety eject menu when my usb-drive used

[Dalai]

The "Safely Remove Hardware" icon in systray is irrelevant. I really meant the drive's context menu.

yes, i have "Eject" item and its work

[Dalai]

Does TC show the icon with a fresh wincmd.ini?

Code: Select all

totalcmd.exe /i="%TEMP%\fresh.ini"

If not, I have no idea why that is.

¯\_(ツ)_/¯

It may be due to restricted user rights. To determine whether a drive is connected via USB, Total Commander opens the drive with name
\\.\d:
and then calls DeviceIoControl with option IOCTL_STORAGE_QUERY_PROPERTY.
When the BusType option is set to BusTypeUsb)or to BusType1394 (firewire) it shows the overlay.

This works when logged in as a normal Windows 10 user, but may not work when logged in as a restricted user.

I have full administrator rights and even more - UAC is completely disabled:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
"EnableLUA"=dword:00000000

Disabling UAC may be the reason.

I highly doubt that. All USB flash drives (except the one drive I mentioned) show as removable on my systems, and none of them has UAC enabled.

2KozakMak
Does Explorer (or any other filemanager) show the drive as removable?

Eject is in red

2KozakMak
So the answer's no. It has the same icon as the other internal drives. It's just like one of my drives I mentioned above: it doesn't get the removable icon (neither in TC nor Explorer), despite having the "Eject" context menu item. Why? I have no idea.

For now I know there are three different kind of drives:

• Regular removable, showing the "Eject" context menu item and the removable icon
• Other removable, showing the "Eject" context menu item, but not the removable icon
• Non-removable (mostly internal) drives which have neither the "Eject" context menu item nor the removable icon

Try a different drive, it might show the removable icon.

...but when i use Drives.dll then everything is displayed correctly.
So maybe worth adding the same verification\check for the key CheckUsbHdd ?

Ghisler might be able to comment on this detail/difference.
