Windows 7: HDD was seen by my PC, but after 3rd party format it is not visible

OK, if the HP Tool is unable to format, your HDD is most probably a goner.

We shall make another attempt to format it with Windows Disk Management.

Right click on where it says RAW and click on Format.

If you still cannot format the drive, you have to check your drive with Seagate Seatools for Windows.

SeaTools for Windows | Seagate

Run the Short Test and if it fails, the Long Test. If it cannot repair the drive as a last ditch attempt try to write zeros (equivalent of LLF Tool and Diskpart Clean all) with it and then try to format it. (Make sure that you select the correct drive)

If all these fail, RMA and get a replacement if your HDD is still under warranty.

If not, you can take out the HDD, hook it up as a second drive and see whether you can access and format it. ( Sometimes, it may only be the interface card inside the enclosure that could have failed and the HDD itself may be OK.)

One thing I had missed: Did you try the external HDD with another USB cable? Try it if you hadn't.

Did you try THIS?

Do only Clean first and try to format per the instructions. Otherwise do Clean All, which will take some hours to run.

I loaded Sea Tools for Windows and ran a short generic and it passed. So I ran the long generic and it failed.
So I ran an Elevated Command Prompt and ran just the "Clean".
And it is 38% into formatting.
If it finishes, which should be hours from now, I will come back and update, as well as mark this solved.

Unfortunately, there is nothing to rejoice here, if what you have stated is true.

The IOmega external HDD uses a Seagate ST350041 8AS HDD and if the long generic test failed I wouldn't put even a cent on it.

Do run the long generic test again with Repair All selected, press the F8 Key and let the test complete. It is going to take a long time and so start & leave it alone.

If it fails to repair and stops dead that is the end of the story.(as far as I am concerned. )

I did not complete the format.
(As you predicted)
But it did "Pass" the Long with the Repair enabled.
So again, I have a RAW, Healthy (Primary Partition) with a drive letter.
So rather than waste time jumping the gun...
Format? Clean? Low Level Format?

I shall write a detailed post on my thoughts later in the day or later after you post the results of this post.

For the time being, I shall draw some lessons from an old SevenForums thread.

http://www.sevenforums.com/hardware-...t-raw-hdd.html

So you can try to format the drive with Gparted. ( I have never tried Gparted and so I may not be able to guide you on that.)

Gparted is available even in Lucid Puppy. So you may download Lucid Puppy (Ubuntu-Compatible Build) lupu-528.005.iso I have chosen this because it is only a 132.6 MB download. http://puppylinux.org/main/Download%...%20Release.htm Create your bootable pen drive with this ISO using Rufus 1.4.6 (58KB) Rufus - Create bootable USB drives the easy way

Boot from this USB pen drive with your external HDD already connected and run Gparted. ( This much I have done .) Exercise caution in selecting the correct drive.

If your external HDD shows all your old partitions, I think you should try to delete them all, create a new volume before formatting.

Format and let us know if that has been successful.

I use GParted at work almost on a daily basis, and I can assure you that it is quality software. Great suggestion.

You can also get a copy of GParted by downloading and burning the Ultimate Boot CD - Download the UBCD

That boot disc is the only one you will ever need.

Hi Torah Lishmah,

You are welcome to share your experience with Gparted if need be and any help is required by the OP.We are never alone .

I was just playing around with the Gparted Partition Manager in Lucid Puppy booted from my pen drive. And here is a question.

I have this Disk 1, a 750GB USB HDD which is RAW. Refer to the screenshot in post #11. Yep, I created it as RAW for this thread. It was initialised as an MBR disk and a simple volume was created encompassing the whole drive but was not formatted. That is why it is RAW. No file system.

OK. Now I formatted it as an NTFS volume with Gparted Partition Manager.( deleted the volume, created a new volume and formatted.)

What I found was that it was formatted as a GPT disk. That surprised me.

HDD was seen by my PC, but after 3rd party format it is not visible-image-1.png

So the question is does Gparted always initialise the disk as a GPT disk? Is it not possible to initialise the disk as an MBR disk? Also in my limited exploration, I could not find anyway to convert a GPT to MBR or vice versa as I could do in Windows Disk Management or most other partitioning/formatting software. Or am I missing something?

Right now I am using Rufus to install lupu on a USB Flash drive. It is on Pass 2 with zero errors.
Then, I will wait for the above question to be answered.
