It cannot be on MMA side: MMW recognizes the devices via MTP.

This appears to be a case of MTP drivers that were 'frozen'. Rebooting solved the problem.

It looks like more and more users observe this:

Maybe it should be checked on MMW side

Isn't it just that the SD card is disabled in options? See the attached screengrab.

I see the same, but it was designed this way that if '[ ] Sync to this location' is unchecked in MMA then the device also isn't shown in MMW interface. It is disabled in my case, I just don't remember whether I disabled it manually in MMA or MMA did it somehow automatically?

You can see at http://www.mediamonkey.com/forum/viewtopic.php?f=21&t=82921 that users have confirmed that the profile is active (and some have confirmed that not only is it active, but it works for Wi-Fi sync but not for USB sync).

In addition, two users at http://www.mediamonkey.com/forum/viewtopic.php?f=21&t=82882 indicated that even after deleting all sync profiles, that when the device is plugged in, MMW does _not_ create a profile for the SD card!!

Also, the eSupport ticket XKC-422-36414 shows that the user has enabled the SD card profile for an S5 (that makes 3 reports of this problem with an S5). Note that it also includes a dbgview log.

Another similar report for the S5 active: GGK-374-42905

Ticket SEW-232-84065 indicates the problem occurring with 4.1.9 and martin includes a forum link indicating that it doesn't occur with 4.1.6.

Ticket BGI-133-36226 seems to be another instance of this problem, but on an LG device.

New ticket 11/13: RRY-205-47901



One possible reason for the growing frequency and why it wasn't being reported as much upon the initial release of MMW 4.1.9 is that the problem may be related to Windows 10. Any other ideas?
Would it make sense for you to schedule a remote access session with the users?
btw, do you have an S5 to test this?

Based on the logs from RUB-786-43900 the SD card is now announced as CD drive that is ignored as ghost CD drive by MMW and removed from the tree.
Creating testing EXE for users to confirm...

BTW: I don't think it is Windows 10 related, because the user from RRY-205-47901 is on Windows 7, no idea what has changed the SD card storage presentation in Windows, probably an Android OS update?

This wasn't the root of the problem, but...

Two users confirmed (tickets XKC-422-36414 and RUB-786-43900) that the issue doesn't appear when MMA is uninstalled or MMA is lower or equals to build number 491. Whenever MMA 499 is installed, the issue appears even if MMA is closed.

So my guess is that it needs to be a change in the StorageInfo.xml file that MMW most probably fails to parse, asking the users for StorageInfo.xml file...

To clarify, the issue started when MMA added this:
<folder>/storage/ext_sd</folder>
for storages with
<type>read-write limited</type>

i.e. MMA added root folder as approwed by MMA user, i.e. whole SD card is approwed as read/write capable, but MMW crashes while parsing the value.

Fixed in MMW 4.1.10.1766


Note that to suppress the crash on MMW 4.1.9 and lower MMA should add the value like this:
<folder>/storage/ext_sd/</folder>
i.e. with the slash at the end
