I purchased several of these drives to use as spares for servers that had the previous generation SATA II 3.0 Gb/sec WD3200AAKS drive. Well as luck would have it, I've had some failures of those old ones and went to replace them, only this drive was not recognized by the computer. After a day of digging, turns out there is a buggy Intel SATA II controller out there in many makes and models of computers that does not properly interact with this particular drive, causing the drive to remain at the 6.0 Gb/sec interface speed and the controller at 3.0 Gb/sec; i.e. no communication possible.

The fix is to place a jumper across pins 5 and 6 which will force the drive to SATA II speeds and make it show up. Unfortunately it doesn't come with any jumpers, so hopefully you have an old computer lying around you can steal one out of.

The same article on WD's site that gave me the fix also said it was possible to perform this fix using a software program they offer called WDSpeed but they refused to give me a copy for some reason and said I had to go buy some jumpers.

Size Name: 500GB Verified Purchase
My use for these drives is to replace a couple of aging five year old 80GB drives in Windows XP and XP Media Center machines. Those drives are still running fine, however, for the price, I had absolutely no reason not to upgrade them at this time.

I came across this drive middle of last week and Amazon was selling it new for $29 - I was scratching my head thinking "what's the deal" and "what's wrong with these drives"? Sure, even though they were above $25, Amazon was still charging for the shipping - so I took two to bring the per drive shipping down slightly. The old 3Gb version of this drive was selling for over $40 - so again, scratching my head about this. Maybe it was a pricing mistake? Whatever - it was a great price.

The drives arrived yesterday, same standard OEM packaging all of my six other WD drives have come in over the past 9 months. I used Clonezilla to clone the old drives on to the new, it went smoothly without any issues. I'm storing the old drives just in case these new ones have any issues I won't have to rebuild the system drives from scratch.

I know that the motherboards in my machines cannot make use of the 6Gb throughput, however, these drives are definitely faster than what they're replacing - older WD drives which indicate they are 7200RPM and 3Gb. Specs on the older drives indicate performance shouldn't be all that different, but it is, and for the better. I won't question it.

The drive indicates you can jumper pins 5 and 6 to limit it to 3Gb, but I didn't understand the benefit of doing it, so I left it unjumpered and it's working well.

To summarize - these drives are fast, quiet, and so far are performing excellently. I'm very happy with them thus far.

This hard drive is the best mid-range hard drives out there. We run a computer repair shop and THIS is the drive that we always use as a replacement in customers computers.

For 500GB, you just can't beat the price. In my 15 years of business I have seen a few hard drive companies come and go, rise and fall. Maxtor was the beast hard drive of all time (until Seagate bought and crushed them). Now, Western Digital holds the best drive, as Maxtor once did.

If you are looking for a great all around basic hard drive, then this is for you. If you are looking for speed and performance such as needed with a "gaming rig" then choose Western Digital BLACK series.

Size Name: 500GB Verified Purchase
We have a Windows XP PC with 250GB hard drive that was getting full with photos and videos. We therefore ordered this inexpensive upgrade to triple the capacity to 750GB total. We ordered the same Western Digital Caviar Blue hard drive as the original since our old drive has been quite reliable over the past 4 years. [Western Digital also makes Green drives that are cooler and quieter, but supposedly not so reliable; and Black drives for gaming performance that we didn't need.] The new 500GB hard drive, as stated, is "bare". That means 2 cables are needed along with it - a data cable, and a power cable. We found this out by contacting Western Digital Tech Support who were quite helpful. We ordered these cables from amazon.com as well: B0001Y8UI4, and B00009YFTI. The ambition was to do this at home; but realized upon opening the PC box that it wasn't so easy - the connections were not easy to figure out including jumper to lower the speed of the new drive from 6Gb/s to 3Gb/s - that Western Digital had warned us about to be compatible with the older PC. Fortunately, a local computer repair shop agreed to do it for only $50 [the same components purchased from them would have been twice as much as amazon.com!] as opposed to Best Buy Geek Squad that wanted over $200 for the same labor. Now, the programs are on the old hard drive [C:] and the data is on this new drive [E:]. The hardware is not a problem; it is working fine as it should. The problem is with software handling the transition of the data. The document folders were an easy fix - change designation from C: to E: for each user. But some programs have been a pain: For example, iTunes had to be directed to E: drive and in the process of rebuilding its library, duplicated all files and also lost the playlists.Read more ›
