Data recovery tools for external hard drive


I have a 2TBexternal hard drive that is no longer showing as a drive within my computer. I have downloaded "EaseUS data recovery" which is reporting the drive as a "lost drive".

I have started running this software and it is finding files. The problem is that is uses all the memory on my PC and then crashes. I have 16GB of memory installed.

Does anyone know of any other good tools to use. Free tools would be the best option.

Best Regards,

Try to use the software called GetDataBack it is one of the best tool for data recovery. Note, the recovered data must be stored on different drive - not on this you recover it from.

The enclosure may be at fault here.
You will have a better chance of success if you take the hard disk out of the enclosure and connect it directly to a PC.
This can be difficult on some USB enclosures which are welded (rather than screwed) together.

Scan it with Testdisk to see if the partition is there/recoverable.
The best would be not to recover the data, but rather just restore what you need from your backups. If for some reason you forgot to backup an important file, then send the disk to a professional recovery agency. Although they aren't cheap, their chances of recovery are pretty good. Or as has been mentioned, getdataback is the best utility to try yourself.

I suggest R-Studio.  The evaluation version is free, and if it develops that there is enough data on the drive to justify recovery you can upgrade to the functional version without reinstalling.  It is expensive at around $US 75, but it has quite a few nice features including search for files by type -- it can search for recognizable file headers, determine the type, and try to recover files even if the directories have been destroyed.

The scan for recoverable files and the recovery will go much, much faster if you remove the drive from the enclosure and connect it directly to the motherboard, as Eirman says above.

Actually the Easeus is a Chineese clone of R-Studio :) I don't think it will act anyway better.
Folks, let him try GetDataBack. Why offer the complicated steps such as disassembling the USB box, restoring from backups etc? Let him do from simple to complex. Try GetDataBack - if it fails - try to open the box and connect drive internally and scan it.
If there is a backup (USB drive is rarely backed up) then there would be no question - how to restore?
with external drives - first check if you get the notification sound when connecting, and check if the drive shows in disk management
if it does not appear - chances are the usb part is bad : usb cable, connector, bridge; - - or the disk itself
so check and replace the "easy" things first, like the cable, usb port, etc

also - does the usb drive have it's own power supply  - and can you post the usb model : usb 2 or 3
usb 3 has BLUE usb connector part in the plug

Thanks for the help. I have not been having much luck getting any data off. I tried connecting the hard drive to the pc but it did not show up. I checked the bios and I could see it but it would not show under the disk management. I will give it another try tomorrow.
noxchoGlobal Support CoordinatorCommented:
So if you connect it via USB then you can see it under disk management but connected directly to SATA it does not show up in Windows Disk Management, right? Are we talking here about the Disk Management you open with right click on My Computer - Manage - Disk Management?
ross13Author Commented:
That's correct. It's a bit strange. I can see the device in the bios.
what about my questions?
is it possible to take the disk out of the enclosure?
noxchoGlobal Support CoordinatorCommented:
Look one more time in Windows Disk Management, maybe it is there but not initialized.
ross13Author Commented:
Still no joy. Why would it show in the bios and not under the windows disk management. Its strange I can "see it" via the USB connection.
noxchoGlobal Support CoordinatorCommented:
Are you sure that you see in BIOS the correct drive? Does it show up in Device Manager?
ross13Author Commented:
I will upload some screen shots.


>>   Why would it show in the bios and not under the windows disk management  <<  in order to show in disk managent - it must be seen in the bios - first step - but if the file system or disk initialision are bad -  it won't show up
