Quick search for partition 5% per 24h - wait or do something else?

#1 Post by Marweecos »

Hi all,

I have a WD 1 GB external harddrive which is not starting up anymore in windows.

After reading and watching YouTube I learned that the testdisk tool might help. Followed the initial steps:
- reading harddisk - ok
- looking for errors - no errors
- look for partitions - no partition
- do a quick search -> seems to be a very long search. I get 5 % per day. After running for 48 hours now I'm at 10%. Meaning I have to let it run for 20 days. Should I proceed or should I do already some other steps to recover my personal data on the drive?

Thanks for any help / advise.

Unless the disk is connected via USB1, it should be faster.
Can you connect the disk via SATA ?

Thanks for your reply.

It seems that the search did find a partition at 16%. It is moving als a bit faster now then the last two days, but still very slow.

Regarding usb I thing it is USB2.0 or 3.0

I am not sure how to connect sata externally, but if you mean directly to motherboard I am not able.
What is your advise?

Unsufficient description!
If your disk is not rotating anymore you need professional assistance.

After reading and watching YouTube I learned that the testdisk tool might help. Followed the initial steps:
- reading harddisk - ok
??? Did you read the label of the cover? "Reading harddisk" is not something that will tell anybody what you did.
- looking for errors - no errors
Imcomprehensible. How did you check for errors?
- look for partitions - no partition
OK!

If you assume that Testdisk would read the disk continuously (which should not be the case during quick search) your transfer speed is approx. 579 kByte/sec. This is roughly more than a hundred times slower than the native linear transfer rate. Something is pretting wrong here.
Either the disk contains lots of broken sectors or the interface is somehow defective or the disk has a major error.

If your external housing does not provice another interface like E-Sata for instance, you would need to remove the disk from the housing.
The easiest thing would be to put it then into a docking station. You should check the performance of the docking station with a proven healthy disk and run Testdisk to compare speeds.

Hearing the sound of the drive when it is connected and feeling it is spinning. Not sure if there is another method to be 100 sure it is spinning.

After reading and watching YouTube I learned that the testdisk tool might help. Followed the initial steps:
- reading harddisk - ok
??? Did you read the label of the cover? "Reading harddisk" is not something that will tell anybody what you did.
I used smartctl -i and was able to get the harddrive information.

- looking for errors - no errors
Imcomprehensible. How did you check for errors?
Later i did the smartctl -a command and it showed no errors.


- look for partitions - no partition

OK!

I will need to buy a docking station then. Any tips for a diy dock station which?

What to do with the invalid or exfat boot partition?

As for the SMART status I don't believe you.

Regarding the docking station you did not even mention the model of your WD drive or the size.
It may well be that you have a integrated 2,5'' model with no standard SATA connector so that it will never fit.
If it's a 3,5'' drive you would need to remove it from the housing.

You did not mention such in your initial posting. Where did it come from? Did it fall from the sky?
Anyway, why should there be one on an external drive?

Your documentation of your problem is really bad.
Am I too strict claiming better documentation?

Sorry if my documentation is bad. I am a newbee and learning day by day. But thanks so far for your help and efforts.

Sorry i thought it was visible in the picture in one of my earlier posts. The drive is a WD10JMVW with 1.0Tb.

It is a 2.5 inch external harddrive.

I thought the pictures were available, but I was the only one who is seeing them. Hope they are visible now.

You did not deliver a proof. From experience I know that I cannot rely on oral statements.

Yes. Looks like I guessed right unfortunately.
You probably cannot remove the USB-connector to make a SATA connector appear behind. I think it is soldered together.
Now a dockingstation is not an option anymore, rather another computer that seems to be working correctly.

Hope this help as evidence
Yes. Looks like I guessed right unfortunately.
You probably cannot remove the USB-connector to make a SATA connector appear behind. I think it is soldered together.
Now a dockingstation is not an option anymore, rather another computer that seems to be working correctly.
Yes it is soldered. What do you mean with another computer that seems to be working? I have a laptop working where I am doing the testdisk quickscan on. What to do with it?

Quicksearch is at 21%. Proceed or stop and do something else to recover data?

The strategy is to exclude error sources. As you pretended your SMART parameters are right, possible sources like cabling, USB-port, notebook hardware or software installation needed to be excluded. This is not necessary anymore based on your SMART data!

Stop immediately and duplicate your dying drive as long as this is possible or engage a professional recovery service.
How come you said your SMART data is OK?
I tinted the relevant lines below.
Now you know why I was asking for a proof.
To be honest, the fact that you came here into the forum is always the first reason to be suspicious.
