Synology Diskstation: Mount external USB drive that has multiple partitions

If you plug an external USB drive into your Synology Diskstation, it gets automounted and you can use it right now.
But NOT if your drive has multiple partitions…because the DS only takes care ofthe first partition on an external disk!

In my case, the first partition was a small leftover from another usage, and my main data was on partition 2. Therefore, I had to manually mount the 2nd partition:

  • (You need telnet or SSH access enabled on the DS for this – check out the patches from Synology to turn on these features)
  • Using “fdisk -L” gave me a list of available drives
  • Lo and behold, my main partition was visible as sdb2
  • Therefore, I simply had to do “mount -t ntfs /dev/sdb2 /volumeUSB1/usbshare” to mount it instead of the empty one that got mounted automatically.
