DiskStation Cannot Read ext4 USB Flashdrive Created in Linux

Unread post by wkhan69 » Mon Nov 20, 2017 12:55 am

DiskStation 6.1.4 cannot read USB flash drives that were formatted by e2fsprogs 1.43.7 (mke2fs in debian linux stretch). ie: USB sticks formatted by tools like GParted in linux or by using:

Code: Select all

mkfs.ext4 -F -L "" /dev/sdd1
I tried 4 different USB sticks ranging in sizes from 16Gb to 64Gb, made by Scandisk and Verbatim. I created a new partition, and formatted them successfully in a debian linux PC with GParted (which essentially uses the mke2fs tool). I tested these USB sticks in a completely separate debian linux system to make sure they work, and they do indeed work. But when I plug them directly to the Synology DS412+, DiskStation cannot recognize the file system.

Note that also, when I format a USB stick from DiskStation, it seems to work fine everywhere. ie: I can use that same USB stick in other linux systems and they can read/write to the USB stick without any problem.

Is this a bug? And advice? The diskstation should be able to read any ext4 formatted USB stick (certainly ones that were formatted directly by linux systems)
