How to read two of this at the same time? I bought two of WD Passport 2TB disk, and I'm going to make copies in these two. But when I plug them into my PC, I found that only one of them can be read. what can I do for this? My PC system is win7. the...

Your computer should be able to read more than one external drive at the time. Most likely, the issue seems to be a conflict of IDs assigned to each (ED) when we connect an (ED), then when we connect a 2nd (ED), then the 2nd (ED) is trying to use an ID that has already been assigned to the 1st (ED), therefore, the 2nd (ED) stays "offline" to avoid a conflict with the 1st (ED). The technical term is "The disk is offline because it has a signature collision with another disk that is online" To make the 2nd and 3rd, and 4th (ED) to be online, then you have to go to: - Computer Management - Disk Management - Scroll down so you can see your external drives - You will notice that the 1st (ED) is "Online" - You will notice that the other (EDs) are "Offline" - Right-Click on "Offline" and a shortcut menu will give the option to turn (ED) "Online" - Wait for a few seconds and now that (ED) will become available to be used. I hope these findings will help you guys minimize your frustrations as I had them before I found this solution

You have two internal hard drives? Not many computers have that. It wouldn't be possible to say which is the quickest without knowing the transfer speeds of both drives. It may not be a significant difference anyways. The edge the external drive would have is that you can easily and quickly remove it and connect it to another computer if something catastrophic happened to your computer. Another thing- as far as I can tell there was no backup software included for the Passport so you'll need to rely on your computer's backup software. That's probably not a factor. In the end it's probably apples and oranges whether you go with an internal or external drive. Personally, I prefer the portability of an external drive. Good luck with your purchase.

I, too, have a Mac and a Windows. I've ended up having separate hard drives for each. Most of my data--years and years of documents and images--are on my Windows computer. I got the Mac because I needed a laptop and didn't want to get Vista. My experience is that I can plug the Windows hard drive to the Mac and it will recognize and read just about everything. The PC, on the other hand, will not recognize the drive from the Mac (at best) or will have a blue-screen tantrum (at worst--so far).

Sorry, no idea. I bought WD (Western Digital) Passport as replacement. That seems better.

Yes, it will be able to view each hard drive independently.It will show two separate drive on your computer when you put into two hard drives.It is support 1 as a backup to the other.Thnak you.

Unless there is a secret I am not aware of, you can only have 26 drives in most windows systems. Not sure about Mac. None the less, one of those drives would need to be your OS as well leaving you with 25. Not everything one plugs into USB is a drive to take up a letter. I dont think that was the intention of having 28 ports. :) So to answer your question, I think the most you could copy is 25 at one time. You could do that using GoodSync.

I'm not a techie, but I'll try to explain the way it works. When you insert it into a USB slot, it asks for a password to Data Traveler. Once you enter the password, it creates 2 drives on Windows Explorer, for me. One drive shows the software (DTL) and another shows the information on the drive. I'm sure this didn't answer your question, but just wanted to explain.

I've heard the reason for the two USB's is in case you have a computer that doesn't provide enough power on just one USB, then you have to use two. It seems to work fine with just one USB with my Compaq (HP) 6730s laptop. I've also tried in on my HP desktop and it also works with just one USB. My thoughts are, try it with one and if it works, great! If not, then you'll have to use two.

You should ALWAYS have redundancy, especially with these kinds of drives. Yeah, they are cheap, but your data isn't. Buy two and use one as a backup. I learned the hard way myself.

B. Meerdink, neither of the two information you brought are backed by the links you posted.I've been searching the internet for the same info D. Wong wants, I'm about sure there is no document on WD's website that will state which is the internal drive interface of "My Passport Essential" products. This is something only reviewers who have opened their "My Passport Essential" drives can tell us. Do you happen to own one of those? Have you opened it up?? Has anyone out there?

did you try one drive at a time? I had the same problem with my drives because they had a signature collision. Had to manually change the signature of one of them. Also, the unit says it will handle 6TB. Not sure it that means 6TB total or will it recognize all 12TB for you.

These drives work fine on Vista. I'm using two on my Vista machine at home. Out of curiosity did the Passport click and turn on and off? I have had that issue with my Passports (80gb and 250gb) on a few computers and it's usually fixed by using a powered hub, a shorter/different USB cable or unplugging all other USB devices connected to the same USB controller. The Passports seem to want the full 5v from the USB port and they will wig out if they don't get it.

As D. Huber said, "diskless" means that you get the NAS box but that it doesn't come with hard disk drives in it, which you must purchase separately. I too suggest you get Western Digital NAS-rated drives (e.g. the "Red" models). Get two of them with the same capacity; some might also suggest that you get them at two different times from two different sources, so as to minimize the possibility that you get two drives from the same, bum batch. Good luck!

I'm afraid so. One drive will work; I'm using two. Even for a "newbie" it's pretty easy to set up, and they're very good about answering questions.

Hi Charles, I have two of these drives, the first one I configured myself to RAID 1, which I use to store my most important files, due to the redundancy. The second drive I left as is, which is RAID 0, which I use as a working drive where I need speed. Once I finish my job and edit the files, I store them on the first drive. I have them daisy chained together and have not encountered any problems. Hope this helps! I love these drives, very fast, good build quality and quiet. Good quality for the money.

All of the disk drives are combined into one logical drive. This means that you would loose the data on your existing drives.As a side note, this unit is very fast. I have had mine about a year with no problems (Windows 7 x64).

Dear Han, I received an answer request via Amazon.com The product is fine. The issue is that the two discs come togehter with something called "array", which means that they are arranged with a RAID so when something is written into the hard drive, it's written in both discs at the same time (mirror array). This is particularly useful for backups so if a hard drive fails (and they do!) you have a second drive in good shape to retrieve the information and then to replace the broken hard drive. You may call this as a redundant backup. I had the same problem than you because the brochure is not so clear about the array and you can think that you're buying some capacity and then it turns out that the capacity is there but mirrored... The good thing is that you can buy more hard drives in amazon.com and expand the capacity :) I hope this helps.
