The problem I manually rsynced a large mp3 directory to an ext4-formatted micro SD card on my Linux computer, proceeded to mount the card on my Cyanogenmod 11-equipped Galaxy S5 with correct permissions, and added the directory to the Sync app with a read-only key. When syncing it manually on the phone, it will start "Receiving" but never finish, with a minimal ~7B/s transfer rate. Details The music folder in question contains 17.07GB and 2872 files. The files are mostly mp3s ranging from 1 to 10 MB in size.The folder syncs successfully between two Linux computers running Ubuntu 14.10, Ubuntu 14.04, and Sync 1.4.103 in the same local (Wifi) network.There's nothing encrypted in the directory.It's music, so filenames vary wildly. There are no characters that are illegal to FAT32 (even though the SD card is now formatted as ext4).The phone is running Cyanogenmod 11 (based on KitKat 4.4.4), but the Cyanogenmod developers have reverted the SD card permission restrictions. I did have to manually change the permissions of the files/directories on the SD card, though (chown -R media_rw:media_rw /media_rw/sdcard1, chmod -R ug+rw /media_rw/sdcard1).Things I tried This problem originally appeared on the Galaxy S5's stock KitKat 4.4.2 ROM. Rooting it and editing /system/etc/permissions/platform.xml solved the (then FAT32) SD card permissions issue, but Sync wasn't able to finish syncing the mp3 folder either. Figuring this might be due to some other arbitrary restriction imposed by Samsung or my carrier, I flashed the latest Cyanogenmod 11 nightly available for my phone, and tried again: no luck. I resorted to formatting the card with ext4, thinking the problem might be related to a FAT32 limitation. One again, no luck. Finally, I tried enabling the tracker server and relay server options for this folder on the Linux boxes. No good, either. What next? Any ideas as to what I might try next? Thanks!
File name "Белов А. В. - Микроконтроллеры AVR в радиолюбительской практике. Автоматика. Радиоэлектроника. Связь. Радио. Радиосвязь. Любительская радиосвязь.(2007)(336).djvu" normally is created in Windows and is not created or synchronized on Linux. The limitation in the file name EXT4 255 BYTES, and the restriction under Windows 255 "characters" in UTF-16. It turns out that in Linux you can create such a file is impossible. Synchronization comes to the first file with this name is long and stops. Tested on Windows 7 and NAS DS213+ — cannot synchronize. Client for Android also cannot synchronize the file.
