    Unable to mount ext4 formatted drive (exited with non-zero exit status 32)

    Hi, I have a 2TB hard drive that was formatted to ext4 for use in a NAS (single drive)

    the drive works fine in the NAS, but when connected to a PC running ubuntu, I get this error message

    Unable to access “2.0 TB Volume”

    Error mounting /dev/sdc1 at /media/ubuntu-gnome/db689d7d-a84e-42ce-b03d-43a5d9ba4c06: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdc1" "/media/ubuntu-gnome/db689d7d-a84e-42ce-b03d-43a5d9ba4c06"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
    missing codepage or helper program, or other error
    In some cases useful info is found in syslog - try
    dmesg | tail or so

    gparted can see the drive and when scanned for errors, it finds nothing.

    I don't want to copy a large amount of data through the NAS as it transfers very slowly when dealing with small files (eg a 2 hour transfer on the PC will take 12-24 hours on the NAS depending on the files)

    I am running a live USB version on the system I want to copy the data to.

    the dmesg command gives this output

    Some NAS devices are known to screw with the code and not write compatible file systems. If you shared the exact NAS vendor, model and release, someone might be able to help more.

    Sorry for the late reply, I am using a WNDR4700 which is basically netgears router a hard drive tray (I mainly use it for bulk storage and DLNA (works okay for larger files (40MB/s write speeds and 80-90MB/s read speeds)

    but those speeds drop to around 5MB/s when dealing with lots of tiny files (eg if I backup a system by booting into ubuntu and then copying the contents of the entire partition windows is on, to a folder on the router)

    (Since I have a bunch of those types of backups, I mainly want to transfer the to a proper NAS for long term storage, and dedicate the 4700 to more of media. (the small file performance is just crap on the router and theres about 1.5TB of data worth of backups)

    I have been meaning to clear the drive up by first copying everything to my true NAS (old PC used as a proper NAS, but nothing seems to want to mount the drive)
