Usb exteral hard drive needs formating

This is a fresh post to the same problem that I posted earlier in the year that remained unsloved and I now have more information about the fault.

I have a Samsung m3 500gb usb external hard drive that I cannot access. What I have done is incorrectly just unplugged the drive without going into the safely remove hardware mode therebye corrupting the file system I think.

The file system should be ntfs but although the disc drive shows up in device manager it does not show in my computer nor can I access it from the software. I am not bothered about the files that were saved on it, I just want to see if I can get it usable again.
How can I reformat the drive ? I am almost certain that the drive is ok, it lights up and you can hear the disc spinning.
My pc is running on xp home 32 bit with sp3.

There is no format facillity available on right click and the samsung software wont read the disc.

Any Ideas would be most helpfull

John

Thanks Ken. The link puts a different slant on the problem. From that link the last post by Synapse suggests taking the drive out of it's enclosure and installing internally.
That's an option in the link I gave above. Worth a try.

Hi DSTM
I tried the format link you gave me. when I go into device manager it sees the drive and says it is working.
When I go in my computer or administrative tools it doesn't show up, so nothing to format.
I don't think the option of installing the drive internally will solve the problem, it is external as a back up drive only.

Hi John. Have you assigned the external Drive a drive letter?
May show in Device Manager but Your computer needs to recognize.

We ask you to try different things for a reason, not always immediately understood. It's a process of elimination.
You said you tried the format link I gave you. What did you try?

Try these steps:

  • Open Command Prompt. (CMD)
  • Type: diskpart
  • At the DISKPART prompt, type: list volume
    Make note of the number of the simple volume whose drive letter you want to assign, change, or remove.
  • At the DISKPART prompt, type: select volume n
    Select the volume, where n is the volume's number, whose drive letter you want to assign, change, or remove.
  • At the DISKPART prompt, type one of the following: assign letter=L
    Where L is the drive letter you want to assign or change.



You can make L any letter as long as it is not already assigned to a drive.

I have attached a copy of disk management screen and also tried the diskpart list volumes.
Both these give the same result Volume 0 drive D dvd-rom
Volume 1 drive E cd-rom
Volume 2 drive C internal main hard drive
Volume 3 drive F This is the card reader on my printer

The external drive does not show upView attachment 2336View attachment 2335

Having now seen both those prints I notice that dvd drive and external drive are both shown as volume 0 could this be the problem ?
And if so do I need to re-consign dvd drive to another number, say 4


Thanks
John

Hi John, those pictures aren't the page we wanted, you are running XP? If so try this, :- click start, then click "Run", in the box either copy and paste this or type it in.

diskmgmt.msc

Then click OK.
You may have to drag the box fully open so we can see all that is shown please.
It is in that window where we can then advise what to do next.

You deleted an image of Disk Management - was this intentional ?
This image shows Disk 0 = The Main Hard drive
The CDROM is listed there as it should be.

Do you want me to reproduce this screenshot ?

Hi Ken
Unsure why I deleted the image, maybe it wasn't the right image but I have uploaded the correct one.
Main drive as you will see is partitioned into c & d and the cd rom and dvd drives also show, but the external doesn't.

Try this, John.

Plug in your USB extenal drive.
Open the command prompt (Click Start -> Run -> type cmd.exe and press Enter)

Type in the following:
diskpart and press enter
Next type
list disk and press enter
see if your extenal hard drive is listed

Hi John

Thanks for the Device Manager image.

This shows you main Hard Drive having 2 partitions - 97 GB and 368 GB

If you take a look at the diskpart image you posted in post #9 ...
It shows a 76 GB partition with no allocated letter.

You are not getting the full information from diskpart > list volume

Mine looks like this :

Microsoft DiskPart version 6.3.9600

On computer: KENSLAPTOP


DISKPART> list volume


Volume ### Ltr Label Fs Type Size Status Info

Volume 3 ESP FAT32 Partition 300 MB Healthy System
Volume 4 NTFS Partition 450 MB Healthy Hidden
Volume 5 NTFS Partition 350 MB Healthy Hidden
Volume 6 Push Button NTFS Partition 18 GB Healthy Hidden

The top one is without a USB Memory Stick - the second set of data is with the Memory Stick.

Your image does not show C: ............which is your main hard drive.

Can you have another go at this please ( diskpart > list volume ) and see if you get the same results ?
Obviously - make sure that the external drive is in place.

==========
By the way ....
Does this drive use 2 USB connections
or
1 USB and a mains adapter ?

Sorry Ken, what I forgot to mention is that I was operating on a 80gb hard drive unpartioned, but I have swapped that for a 500gb drive that is partitioned.
Hope that explains the difference. the reason for the swap is that I am trying to run 2 x 500gb drives on raid, to replace the 80gb drive but that is another story.

Hi DSTM
Tried that, and the hard drive is not listed, only the main hard drive showing 466gb.

Hi John.
We have suggested all the normal checks and nothing is working it seems.
You have an aging OS/Motherboard. Could even be a motheboard/USB/PSU issue.
Would be interested what your 12v rail readings are as well.

I it were me I would remove the Drive out of it's enclosure as carefully as possible not to bump the drive and hook it up directly to a SATA port on the Motheboard bypassing the USB all together. You only have one Drive internally so you have a spare Power plug from your PSU.
All you need is a Sata cable from the motherboard Sata port to the hard drive.Reboot and If the Hard Drive still can't be read then It looks like it can be used for a doorstop.

DSTM has a valid point.

If you need a SATA cable take one from the DVD or CDROM if they are SATA.

You didn't answer this ...
