I'm in a huge panic right now because my external HD won't mount! It's a 2TB WD Elements that's about 4'ish years old. It was working fine this morning but just now when I tried mounting it, it was seriously lagging and I thought it was a problem with my laptop so I restarted my system. After rebooting my MBP, my external drive just wouldn't mount at all and I got this error message:

Tuxera NTFS could not mount /dev/disk2s1
at /Volumes/FRANCOIS because the following
problem occured:

Aligned I/O enabled.
CBCIO enabled.
WARNING: ReadFully - I/O error while reading from
file (5: "Input/output error")
WARNING: failed at pread(3, 0x102180000, 524288, 3220701184);
WARNING: bytesRead=0
ntfs_attr_pread_i: ntfs_pread failed: Input/output

Failed to calculate free MFT records: Input/output
error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run
chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f
parameter is very important! If the device is a SoftRAID/FakeRAID then
first activate
it and mount a different device under the /dev/
mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the
'dmraid' documentation
for more details.
I tried mounting it on Windows but I can't access it AT ALL, I see it as a HD but there's no indication of its size etc and I even got the message error saying it needs reformatting (!!!) suggesting it's practically a blank! I don't know what to do and am near tears now.

Please help! I have a lot of important files and data which I can't afford to lose in this HD and I really would like to recover it if possible!! Thanks!

EDIT: Gah! HELP! I tried mounting it again after a failed attempt at repairing the disk ala DiskUtility and I got these TWO error messages

We always advise users to stay clear of Tuxera and other free schemes such as NTFS 3G because they are known to cause I/O write errors. The only driver that is recommended and stable is Paragon NTFS which you can buy for $19.95.

You can not repair that disk using Disk Utility! You're going to need a Windows machine in order to repair it. Try mounting the drive to a Windows machine. If Disk Manager can "see" it, you can try a repair using the Windows utility. (chkdsk)

But all hope is not lost? This can definitely be fixed and data won't be lost?

That remains to be seen. You're going to have to try repairing it as I suggested above before you know if your data can be recovered.

hi guys,

I just have simillar issue and error. But I did further steps and still didn't get any solution.
So I have external hdd 2TB Seagate which was formatted under Windows to NTFS file system. I was using it with success on my Mac and Windows machine. My Mac has OSX Fuse and Tuxera-NTFS.
When I connect Seagate to Windows there is no errors and I can read/edit all files. On my Mac I get error as the user above. I ran chkdsk under Windows also with bad sector searching and repair option on (took a few hours) but it didn't fix the issue with mounting on my Mac.
What else can I check/perform?

As noted above, Fuse, NTFS 3G, and Tuxera all cause problems - specifically i/o write errors. The only driver we recommend using with your Mac to read NTFS is the Paragon driver mentioned above.
