I just installed Ubuntu 14.04 and I can't mount my `exFAT` HDD.

I get the following error:

```
Unable to access “SeagateHDD”
Error mounting /dev/sdb1 at /media/me/SeagateHDD: Command-line `mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,namecase=0,errors=remount-ro,umask=0077" "/dev/sdb1" "/media/me/SeagateHDD"' exited with non-zero exit status 1:
stdout: `FUSE exfat 1.0.1
'
stderr: `ERROR: `Operating Systems' has invalid checksum (0x281c != 0x2450).
'

```

I installed `exfat-utils` and `exfat-fuse` using apt-get but no luck.
I also tried the repository `ppa:relan/exfat` but I got:

```
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 fuse-exfat : Depends: fuse-utils (>= 2.7) but it is not installable
E: Unable to correct problems, you have held broken packages.

```

Can anybody give me a hint? All my backed up data is on that HDD.

**EDIT:**

The output of `$ sudo apt-cache policy exfat-fuse` is:

```
exfat-fuse:
  Installed: (none)
  Candidate: 1.0.1-1
  Version table:
     1.0.1-1 0

```

Tried it on a Linux Mint and had the same problem. Also tried mounting it on a Mac and it worked perfectly so the data is not corrupted.

**EDIT2:**

It appears it was a problem with my HDD which apparently I unplugged from the USB port without unmounting and it had a checksum error. What I did was I plugged it on my Mac and it automatically did a `fsck_exfat` disk check which fixed the problem and I could load it on Ubuntu as well. I think a similar thing could be achieved on Ubuntu as well, but I don't know which tools to use to do so.
