mount external usb hdd on FreeBSD

This hard drive works completely fine on Ubuntu.

Here is what happens when I try to mount it on FreeBSD:

Code:

# dmesg

...

da0 at umass-sim0 bus 0 scbus0 target 0 lun 0

da0: <Seagate Expansion 0710> Fixed Direct Access SPC-4 SCSI device

da0: Serial Number NAARJKXT

da0: 40.000MB/s transfers

da0: 1907729MB (3907029167 512 byte sectors)

da0: quirks=0x2<NO_6_BYTE>

Code:

root@generic:/dev # ls -la | grep da

crw-r-----  1 root  operator  0x66 Nov 21 00:53 da0

crw-r-----  1 root  operator  0x7e Nov 21 00:57 da0s1

Code:

# gpart show da0

=>        63  3907029104  da0  MBR  (1.8T)

          63          1      - free -  (512B)

          64  3907024065    1  ntfs  [active]  (1.8T)

  3907024129        5038      - free -  (2.5M)

but:

Code:

root@generic:/dev # mount /dev/da0 /mnt

mount: /dev/da0: No such file or directory

When I tried plugging it into my NetBSD computer I got a different error:

Code:

# dmesg

...

[ 1301438.693912] sd0 at scsibus0 target 0 lun 0: <Seagate, Expansion, 0710> disk fixed

You may need to specify the file system type as NTFS, & you probably need to mount a slice/partition, not the whole disk, try da0s1, (or perhaps da0p1).

(You may need ntfs-3g to get read/write access.)

Since inside /dev there is both da0 and da0s1, I tried every mount_<var> option (ie. `mount_nfs, mount_cd9660' etc) for both da0 and da0s1, but nothing. (Even `mount -t ntfs/nfs/cd9660 etc' and still nothing.

`gpart show da0s1' wont show anything. I'm not sure what da0s1 even is. The kernal/dmesg says da0 is the Seagate HDD though, there is no problem detecting the HDD it seems.

I shouldn't need to reformat this HDD at all, it works 100% fine on Ubuntu, auto detects and mounts, I can copy and modify files to and from it etc.

I just don't understand what the problem could be.

By the way I am running FreeBSD 12.1 on ARM64 (Raspberry Pi 3 b+) if that is at all relevant. The USB keyboard that is also plugged in has no problems.

I will try mounting a small 16gb USB and see what happens, but apart from that I'm all out if ideas.

I don't use FreeBSD, but do use OpenBSD on occasion, this is the syntax that I use, as the root operator.

Code:

mount -t ntfs /dev/da0s1 /mnt

(/dev/da0s1 is the first slice/partition on that disk)

((Running FreeBSD on arm64 has no relevance to your problem.))

Check that you actually have an NTFS file handler in (probably) /usr/sbin

P.S. The permmisions might be another clue...

Not sure why NetBSD has it as offline(?).

You might want to look up auto mount for bsd as well. I'd be more detailed if I wasn't on my phone
