Hey there Homura15

Just would like to double confirm, can you copy the file to a different location (not to the external drive?)

Most likely there is a problematic file, or problematic portion of the disk that is causing this error then. Like mentioned by wildwestgoh I would suggest running a chkdsk on the machine, which might fix a problematic file issue and might be able to correct a minor disk error.
How to run Chkdsk from My Computer or from Windows Explorer
Double-click My Computer, and then right-click the hard disk that you want to check.
Click Properties, and then click Tools.
Under Error-checking, click Check Now. A dialog box that shows the Check disk options is displayed,
Use one of the following procedures:
To run Chkdsk in read-only mode, click Start.
To repair errors without scanning the volume for bad sectors, select the Automatically fix file system errors check box, and then click Start.
To repair errors, locate bad sectors, and recover readable information, select the Scan for and attempt recovery of bad sectors check box, and then click Start. Note If one or more of the files on the hard disk are open, you will receive the following message:
The disk check could not be performed because the disk check utility needs exclusive access to some Windows files on the disk. These files can be accessed by restarting Windows. Do you want to schedule the disk check to occur the next time you restart the computer?
Click Yes to schedule the disk check, and then restart your computer to start the disk check.
I would recommend Running it to repair errors and locate bad sectors in this case.
Hope this helps.

Good Day Homura15

Well If the scan is experiencing too long to recover bad sectors or not responding it means that the scan functionality is no longer applicable. In this case I'm afraid that your HDD is about to die.

The option you have now is to backup all your data from your HDD if possible to avoid any data loss, and if the HDD is still under warranty, then you can proceed to RMA it.

Here is the link for you to proceed with the RMA process:

Good Luck!

Hey there yuk4ming,

Just would like to double confirm on your issue, is your drive still under warranty??
Have you checked the warranty status in the WD website??

If so, what region or country that showed up after you have keyed in the serial number?

Never the less, you could try getting in touch with WD customer support and get your RMA process sorted out.

Here is the link for the WD customer support hotline.

Hope this helps.. Good luck!!

Hello yuk4ming,

Well what I meant by keying in the serial number is actually one way to check on your HDD warranty status through the website.

Since you mentioned that you have already registered the product, then your product's warranty information would appear in your account so there is no issues with that.

The best way for now I would suggest that you get in touch with the customer support and get the RMA process sorted out.

Just keep me updated once you have done with the call to the customer support alright.

Good luck!

Hey there Maxieos

Everyone usage on storage device is pretty much different. It depends on how well you take care of it or organize your partition in a correct order. In fact every drive will fail eventually, it all depends on how you take care of them

Just a reminder, even if you have a drive solely for storage, it's always not safe as well. Its best that you always remember to have backup your important files at all time to avoid any system crash, virus or even sometimes natural disaster’s.

Try getting drives that offer the best combination of reliability, low-price and performance at a given storage capacity point. More higher performance than the value-only recommendations, usually at a slightly higher price.

Just a thought of sharing, hope you find this useful.

Hey there Maxieos

If you going to do that way, then I presume it shouldn't be any problem.

Just be sure that you always get an extra 1 to have your backup’s just in case.

Well the WD Black drives are considered the performance line and have a few features that the WD Blue drives don't have, but there is not much difference in real world speed. They are both 7200RPM drives. The WD Blacks drives have a better warranty though. 5 years vs 2 years on the WD Blue drives.

Hey there Maxieos,

Just would like to share to you in regards to changing the RPM in a drive.

Changing the actual RPM is not possible. Modern drive heads float over the surface of the disk and do all of their work without ever physically touching the platters, they are magnetizing. The amount of space between the heads and the platters is called the floating height or flying height. It is also sometimes called the head gap, and some hard disk manufacturers refer to the heads as riding on an "air bearing". The read/write head assemblies are spring-loaded--using the spring steel of the head arms--which causes the sliders to press against the platters when the disk is stationary. (This is done to ensure that the heads don't drift away from the platters; maintaining an exact floating height is essential for correct operation.) When the disk spins up to operating speed, the high speed causes air to flow under the sliders and lift them off the surface of the disk--the same principle of lift that operates on aircraft wings and enables them to fly.

The distance from the platters to the heads is a specific design parameter that is tightly controlled by the engineers that create the drive. By adjusting the strength of the springs to match the other drive parameters (such as the speed the disks are spinning and the size and shape of the heads) the float height can be precisely maintained.

I think it would be safe to assume that changing the speed of rotation of the platter, would also affect the amount of lift created and would either cause the heads to float to high, to the point where it could not read from the disk, or too low and could cause a head crash.

If let say you are using Linux system, have a look at hdparm utility. Unfortunately, it doesn't allow you change HDD RPM but it allows you change some low-level performance options. Be careful, some options could be dangerous.

Just a thought of sharing, hope you find this information useful.

Hey Maxieos,

Yup, it's definitely a risky one.

Well, alternatively you could try running the DLG(Data Lifeguard Diagnostics) for your drive to determine the health status. Just bear in mind that for DLG, it can only help to read the status and not fix any bad sectors. Here is the link on how to do so:

Please do share to us the test results.

Hey there Moogle Stiltzkin

If you have checked the HDD health status, and found that “CAUTION” is written under Health Status, it can be a bad sector on HDD.

Sectors are reallocated when they’ve gone bad (a hardware fault on the drive). Modern drives are built with spare sectors precisely for this purpose, but a large number of reallocated sectors indicates that there is a more serious problem with the drive and it is likely to fail soon. This is also likely to contribute to the slowness of your PC.

Alternatively you could try running the DLG(Data Lifeguard Diagnostics) for your HDD just to double confirm on that. Here is the link on how to do so:
http://products.wdc.com/support/kb.ashx?id=4rQJdl

The best option now is to backup all your data from your HDD if possible before it fails catastrophically, and if the HDD is still under warranty, then you can proceed to RMA it.

Hope you find this information useful, good luck.

Hey there Maxieos

I would rather say that both feed the same purpose which is to run a test to determine the HDD status. SMART test is more to like checking all the hardware whereby the DLG is more specific in HDD. With the DLG you can run more than just a SMART test which is the EXTENDED TEST.

This test performs a Full Media Scan to detect bad sectors. This particular test may take several hours to complete depending on the size of the drive but then it will give you a full review on your drive.
