LOST MY EXTERNAL HD (accidentally deleted the Partition)

post #1 of 12
Thread Starter 
Hi folks,

I accidentally deleted the partition from a completely empty external hard drive, (250 GB Western Digital), and because 250 GB of external hard drive is pretty cheap these days I'm not about to spend $40 or $50 to recover the partition. At this point the disk will show up in the Disk Manager's lower section listing it as "Disk Number 7" but it does not show up in the upper section where the remaining hard drives I have, (as well as partitions), do show up.

The only options I am given in the Disk Manager for that hard drive is when I right-click on it. I can convert it to "Dynamic disk or MBR" and I also have access to the "Properties" section, (I wonder if uninstalling the Driver would help). I've already tried disconnecting and reconnecting the hard drive, rebooting the computer with the hard drive connected, and frankly spent more time that I think the hard drive is worth. But rather than throw it out I thought I would check here.

One more thing; in the Lower Section of the disk management control it states that Disk 7 has "232.76 GB unallocated" it also states that it is "Basic" and "Online". Does anyone have any suggestions as to how I can make this drive visable again? I guess what I'm looking to do is recover the partition but like I said, I'm not going to pay $40 for a program to do that.

There are all kinds of freeware programs out there many of which require I download some form of advertisement or download manager, (I'm up to my ears in download managers), and even then I'm not sure which one will really work. Any suggestions will help.
Thanks

When you right click on the drive in Disk Management you are not given the option to partition it ? If you are given it, select it, and after that format it.

No, Unfortunately I do not get that option TPI2007.

Thanks Sean, I have several HDD testing programs including HDTune. I also have Seatools but HDtune is showing that the drive is fine. I can do any test on it and it passes nicely.

But then again, I only have "health Check" and "Error Check" on HDTune that I think will do any worthwhile testing. So I'll look into that "TestDisk" but in the meanwhile, if there's any other suggestions you all may think of, please do let me know.
Thank You.

Test disk may allow you to recover the partition. It is not a HDD testing program.

TestDisk can scan for partitions and rewrite the partition table, making the partition reappear. This is assuming (of course) that the partition is undamaged. If you format overtop, then... well, good luck. tongue.gif

Thank You All!
One last question before I try this out; Keeping in mind that other than the partition, I had no data on the disk before I screwed up, is it possible to "Rebuild" the HD? I mean, WD had to start from somewhere, right?

So if I were WD, and I was producing this HD, I guess I would have a way to install the nessessary info that tells the HD and the computer that it attaches to, what it is. I wonder if I called WD, if they'd be willing to let me get that software, (I know it's a long, long, shot and it will be my last resort).

Does that make sense to anyone? Or am I way off on the way these things work?

Anyway, I'm going to give Test Disk a try right now and if it works, great! if it doesn't, I'll probably chase the WD tail and see what happens. And if I strike zero, then I'll use the HD for some trap and skeet shooting next week smile.gif
Thanks

PS I went through a lot of trouble to update my system info the other day, and apparently none of it 'stuck'! Gonna have to try again.

PSS That's better.

uuummmm, i do get the problem then, do you even have a problem? o.0

Let me get this straight...

You had no data on teh drive and you accidentally deleted teh partition or something but right now it has no usable space because it has no formatted partition?

So all you need to do is format it so you can actually use it? Or am I missing something?

Do this:
  1. Open the Start Menu, type diskpart, press Enter
  2. Type list disk, press Enter
  3. Type select disk X (where X is the number your drive shows up as), press Enter
  4. Type clean, press Enter
  5. Type create partition primary, press Enter
  6. Type format quick fs=ntfs, press Enter
  7. Type assign, press Enter
  8. Type exit, press Enter

Thank YOU SEAN!!!

You did it!!!!thumb.gif I downloaded the 64bit windows version of Test Disk, followed the instructions TO THE LETTER, (for anyone who may want to try this fix), and rebooted. VIOLA, there it is again, all 232gb, (out of the 250gb), and it is usable!

I'm going to the TES DISK website and I'm going to make a donation. The program savved me at least $40 or $50.

I really appreciate the help from you all and as I have always said since the first day I joined Overclock.net, this is a great site with great people who will lead you in the direction you need to go when you're lost!smile.gif
Thanks again.
Rich

BTW Sean, I do have one more question; I won't go into the long story but in my frantic attempt to regain the external hard drive yesterday, I inadvertently created a 100mb partition in my main boot drive, (in my case, the C: drive).

Before I had lost that external drive it was lettered "J" by the system and then somehow, after I lost that drive I must have created a 100Mb partition in the main drive but it didn't have a letter. Thinking that this was my answer to the missing drive, I assigned a name for it: the letter 'J'.

So now my main drive has the 'D' partition,(factory Image), the 'C' partition, (my 'Main system disk'), and this 'J' partition which seems empty but when I place my cursor over it, it shows that it is 99.9mb in size with 70mb of free space.

I think that's because every time you make a new partition, you create what I guess is called the MBR that Identifies it. So I wanted to get rid of it but I'm afraid that I could be misinterpreting what this partition is all about. Am I safe to delete that partition and return the 100mb back to the main drive or is it just better to leave it alone and maybe even "un-name" it so that I can't screw around with it by mistake?

Thanks
