My wd 320gig gets an i/o error after drop and draging any files, that is to big like 50mb an up,but it comes on normally when plug in my computer, I could acess infomation but can not put in...

Hi jumbeezt,
Have you tried right clicking on the file and using the "Send To" function? If that is not an option, try right clicking and Copy the file, goto the HDD and right clicking in the folder you want the file to be in and then Paste. If this does not solve your problem, post a comment in this thread and tell me exactly what the error message is.

How to open the case of a my book wd 320gb

Sounds like the drive in the thing is shot or the controller itself.
I remember a friend having one of those I dont recall it having any screws but it did have a snap apart case. Use a thin flat head screwdriver to locate and snap apart the catches. 
If you can get into the thing to replace the drive and get the same result then the controller is shot and you will not have any luck fixing it unless you are good at surface mount soldering.
For now, check that the cables are good and that you are connecting it to a good port on your computer.
It is not uncommon to have external drives go kaput for seemingly no reason. The drives they tend to use dont like to be moved AT ALL when they are powered on, this is not condusive to an EXTERNAL case as it is too easy to move around.
Good luck. Let me know if you have any problems getting it apart, I can look up my friend and take his apart, yea hes cool like that.

My WD 500g external storage unit started to fail me. The USB connection broke off into the actaul WD outer case. I opened the case and took everything apart except the actual drive. I am wondering what...

Buy a new "empty" external disk-drive case for $30.

Pick one that has "data" and "power" connectors that are compatible with your current disk-drive.

Put the disk-drive into the new case. Done.

Can only see one WD Passport 320GB drive at a time.

This is most likely a classic case of them trying to occupy the same drive letter. If you open disk management Start > Run > type 'diskmgmt.msc' and you should see them both there - One with a drive letter and one without, simply right click on the drive which doesn't have a drive letter and select 'change drive letters and path...'. Change the drive letter to something you know doesn't really get used and they should both appear in my computer.

Hope this solves your problem.

Folders wont load or delete

That My Book thing is a pain in the rear. You need to check that your computer has USB2.0 and not 1. if it is 1.0, you'll take forever to do anything on the drive.

Confirm that you have USB2.0 rather than 1.0 before we could move on.

Yes. The case doesn't care what size the drive is. The computer is just asking for the USB driver for the case. Check the WD site for the driver for the model of MyBook that you have. That should cover it.

Cannot communicate with my book

Try a replacement USB cable first, and test the MyBook on a different computer, to ensure the fault is on the external storage unit.

There are two possibilities:

The Mybook USB/ATA controller board is faulty.
In this case you can simply take apart the enclosure and mount the disk into a new enclosure. WD Mybooks are SATA, but double check the hard disk connector to ensure.

The hard disk inside is faulty.
In this case repair may be expensive. You need to locate a data recovery facility with a 'clean room' , the cost is usually more than $800.

If this happened after a power surge, then the problem is most likely a faulty controller board.

If instead you have dropped the hard disk it is possible an hard drive failure, in that case repair will be expensive.

A replacement enclosure will stfrom art about $20 on Ebay or Amazon, and must not necessarily be WD .
Check if your disk is Sata or PATA (IDE) before buying the enclosure.

How to open the case of a my book wd 320gb

See my response to someone else at the following link: . Not sure if the WD My Book you are trying to open is the same as a 500G. Mine has a black case, resembles a book and measures approx 7" high x 5 1/2" deep x 2 1/4" thick. I was able to open my WD My Book 500G drive but not w/o tearing up the rubber around the edge. Once I got it open, I discovered that there are tabs at the top and bottom of the case. The tabs are recessed w/i small rectangular holes and hard to see unless you look at it w/ a bright light. The tabs are located about 1 inch from the front edge of the drive on the top and bottom. It appears that you have to depress both tabs w/ flat tip screw drivers (or some other similar device) while pulling on the sides of the casing - you almost need three hands (maybe even more) while trying to get it open. The rubber around the edges fits tightly so it is extremely difficult to pull it apart w/ the rubber still in place. There must be some other trick to opening the case but I'm not sure what it might be. Not sure what you can do once you open it unless you have another drive that you can swap parts w/.

Good luck. Let me know if you figure out how to open the case w/o tearing up the rubber.
