Well, I'm not sure where to turn next as I think I must be missing something fundamental.
I removed the hub from port 1 and plugged the thumb drive directly into port 1 with no change in result.
I tried a different thumb drive with no change in result.
I re-formatted the thumb drive as fat32 with no change.
I think early mount is actually working because when I turn it off, I see nothing in /tmp/mnt. When I turn early mount on, I see /tmp/mnt/3CE4-ADBC so at least the drive is appearing. What I don't get is why I can't see the MSHEETDIR folder there. Do I have to do something else to make it appear?
I have verified that the /media folder is at /tmp/media/usb/USB1/3CE4-ADBC both via Dolphin and windows explorer. In windows explorer, I verified that the folder was empty then used cp /msheets/* /tmp/media/usb/USB1/FCF9-C644/MSHEETDIR (via Telnet) to copy the files, then watched the files appear in the folder, eventually returning to a # prompt. I also used dolphin to confirm that the files are now in MSHEETDIR.
I then used WEC to set MSHEETDIR to /tmp/mnt/3CE4-ADBC/MSHEETDIR, then hit save. Before restart, I verified that I can't see MSHEETDIR in /tmp/mnt/3CE4-ADBC but I wouldn't expect to yet.
Reboot WDTV with Web Frontend.
The /msheets folder is still fully populated so I don't think this worked but I'm doing this remotely so I can't verify for sure.
I still can't see the MSHEETDIR folder in /tmp/mnt/3CE4-ADBC. Should I be able to?
Do I need to try a third thumb drive?
Is there an accepted standard for formatting the thumb drive? I assume that if I can copy to it with cp in Telnet, it's working as expected.
Not there yet.
KAD wrote:the script that executes MSHEETDIR runs very early in the boot process and from the investigation you did
it is not available when the script runs
you said you enabled early mount - which is what is required
but for wharever reason it's not happening
early mount is always done under /tmp/mnt/<UUID>/....
until you can get the drive to show up in /tmp/mnt/... MSHEETDIR will not work
at least now you know what to trouble shoot
here's what I would try
plug the thumbdrive in directly to the WD
and the hub can use the other port allowing access to your hdd
