Slow transfer speed in WD BLACK

faisalthegamer · Jun 5, 2013

I have 1TB WD BLACX HDD, when I transfer a file from one partition to another, it starts at 120 mb and slowly comes to 20-30 mb. Please help me.

Even if I transfer a file in the same partition, the result is same.

Are those partitions on the same drive? File transfers are faster from one drive to another. If the partitions are on the same drive, the heads have to thrash back and forth as it reads and writes to different locations on the drive.

Yes, the partition is on the same drive. But is the speed 20-30 mb good for a WD Black?

Do you have the model for that drive? I'd suspect it can get that low. Also try copying from the WD to another drive, then back from the other drive to the WD and see how it responds. It helps if the other drive is as fast as the WD

wd1002faex. I transferred to my WD Essential external and from that to my internal, the result was same.

That's not good. Updating your chipset drivers may fix it. You can also download WD's data lifeguard and check it for errors. If there are problems, RMA the drive.

That is my mobo, now what should i update? I have windows 7 32bit.

If your bios is set to use AHCI (which it should for SATA), then you want Intel® Rapid Storage Technology ver. 11.6.

It won't hurt to check the drive with datalifeguard that I posted a link to earlier.

In the bios, it is set as IDE. And as for the datalifeguard, I did the quick scan, it showed no error. The full scan estimated time is 1 hour 30 min, will do that later, and posted the result.

If you want, here are instructions to be able to switch the bios over to AHCI. Don't attempt switching the bios unless you do this registry fix first. You can also google "IDE to AHCI after installing OS".

Is that safe to do? Do all people who have WD Black do this? If no, then why do I need to do this?

Hawkeye22 · Jun 6, 2013

Most everyone that has sata drives and an OS that natively supports AHCI (windows 7) has their bios set to AHCI. As stated in the article, AHCI supports additional command features that IDE does not, NCQ (native command queing) being the big one.

If you don't feel comfortable doing this, then don't. Research it a bit and decide. There are plenty of posts here on Tom's Hardware regarding this.

My only question is, will it damage my hdd?

Hawkeye22 · Jun 6, 2013

No. It will not damage the drive.

faisalthegamer · Jun 6, 2013

BTW the lifeguard test, both, quick and extended test, came passed.

faisalthegamer · Jun 9, 2013

Dude I did like you told me, now the speed is around 40-50. So is my HDD failed ?

. I bought it just 1 week ago.

Hawkeye22 · Jun 10, 2013

You mean switch to AHCI, update your chipset drivers, or both? If you've done both, I'd contact WD and see if they can offer any suggestions or get you an RMA.

Also, I forgot to ask... was this drive partitoned and formatted with win 7 or was it done with XP or some other OS? If it was formatted with XP, the sector alignment is probably incorrect. If this is the case, you can use the alignment tool from WD to correct it.

I switched to AHCI. which chipset update should i DO?

faisalthegamer · Jun 10, 2013

Intel® Rapid Storage Technology ver. 11.6?

Hawkeye22 · Jun 10, 2013

Yes, RST 11.6, also note that I updated my last post. See the comment regarding sector alignment.
