Need Assistance in Recoviering the Data from my External HD (Transcend 500 GB)

Dear All;

I am using Transcend 500 GB External HD (USB Model) over the past 4 years. Since last week, it is not mounting in my Mac Book. I am getting the Following Error Message:

Tuxera NTFS could not mount /dev/disk2s1
at /Volumes/Anandh - 500 GB because the following problem occurred:

Aligned I/O enabled.
CBCIO enabled.
WARNING: ReadFully - I/O error while reading from file (5: "Input/output error")
WARNING: failed at: pread(3, 0x100580000, 524288, 3220701184);
WARNING: bytesRead=0
ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read NTFS $Bitmap: 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.

When I enquired with my Brother - In - Law; he said the External HD has crashed and that the only way to recover the Data from the External HD and format the disk completely.

Need your assistance ASAP, as the Data are very Valuable and mostly Company Performance Data.

Thanks and Regards;

Don't reformat the drive

AS it is an NTFS formatted drive you may need a windows machine to properly troubleshoot the drive

If the drive will mount on a Windows PC do this:

Open a command prompt. Assuming the drive mounts as D, change the command prompt to D and then type the following at the command prompt:

chkdsk /f

That will initiate repairs on the drive. If the drive won't mount on a Windows PC, it could be defective. In that case, recovery may have to be done professionally which is very expensive.
