New User Needs Help Recovering 2TB External Hard Drive

#1 Post by redbeard61520 » 24 Apr 2013, 16:36

Hello Everyone,

I am new here and in dire need of some help from the experienced people in this group.
I was reformatting a bunch of re-writable dvds and inadvertently formatted my external
hard drive. I stopped and canceled the process within a minute after realizing what I
did but I am now in a position of being unable to recover the information on the drive.
I have about 1.5 TB of family pictures, personal files, music, and video on this hard
drive that I need to recover. The family pictures, personal files are irreplaceable!

That's where you incredibly smart individuals in this group come in. Fiona? Remy?
I've seen you help others and would greatly appreciate any help you could provide.

I am using TestDisk 6.14-WIP 32 bit version on Windows 7.

The hard drive in question is an Hitachi Easy Device 2TB hard drive.
I started TestDisk, created a new log file, and the first screen shows:

>Disk /dev/sda - 640 GB / 596 GiB - Toshiba MK6461GSYN
>Disk /dev/sdb - 2000 GB / 1863 GiB - Hitachi Easy Device
Drive C: - 107 GB / GB / 100 GiB
Drive D: - 510 GB/ 475 Gib

I selected the Hitachi drive and on the next screen I selected "Intel".

On the next screen I saw this:

>Disk /dev/sdb - 2000 GB / 1863 GiB - Hitachi Easy Device
CHS 243201 255 63 - sector size-512

Next I selected "Analyse" and the screen showed this:

>Disk /dev/sdb - 2000 GB / 1863 GiB - CHS 2432014 255 63
Current partition structure:
Partition Start End Size in sectors

Invalid NTFS or EXFAT boot
1 P HPFS - NTFS 0 1 1 243200 254 62 3907024001
1 P HPFS - NTFS 0 1 1 243200 254 62 3907024001
No partition is bootable

Next I select "Quick Search"

After quick search, the screened showed this:

>Disk /dev/sdb - 2000 GB / 1863 GiB - CHS 2432014 255 63

The harddisk (2000 GB / 1863 GiB) seems too small! (< 4692 GB / 4370 GiB>)
Check the harddisk size: HD jumpers settings, BIOS detection...

The following partition can't be recovered:
Partition Start End Size in sectors
> HPFS -NTFS 385000 53 50 570513 90 61 2980268688

This is where I now sit. I feel sick to my stomach.

Does this mean I am totally screwed???

Fiona? Remy? Others? Can you please help me out here? I am truly desperate!!!

James

Hello again,

I've replied to my own post to provide some more information which
might help in ascertaining if and how I may recover my lost partition.

I am using Windows 7 Home Premium 64 bit version
I am using TestDisk 6.14-WIP 32 bit version as suggested in forums.

Here are relevant screen grabs of:

Windows 7 Computer Management:

In the next post I will post the TestDisk screen grabs.

Well, now that I've got all this posted, I'll be patiently waiting
for a reply from whoever decides to help me out with this thing.
Rest assured, I'm patient and willing to wait a looong time in
order to get help from you fine folks because that hard drive
has irreplaceable photos and files that I must absolutely get.

Finally, I would like to also mention there are probably over
a million files on my hard drive in hundreds of different
directories. So if you thing any commercial recovery software
would do a better job than test disk, please feel free to point
me in the direction of any of the ones you consider best.

Money is no object when it comes to recovering this hard drive.

Thanks in advance for any help you can provide.

Cheers!!!

James
