I just bought an external hard disk yesterday (My External Hard Disk is Plug and Play type). But,now I have a problem in my PC.

The problem is:

1.Sometimes it is not detected or Took a very long time to be detected.
2.If it is detected, sometimes it is
a.Disconnected when copying a file and connected again.
or
b.Constantly changing between disconnected and connected. Even viewing what inside the external hard disk automatically disconnected.

When I'm running a CHKDSK on it, it shows a file that is completely unreadable, but in my laptop it doesn't show that file or any file that completely unreadable.

I'm using Windows XP SP2.I'm using the same USB port that could recognize it yesterday and this afternoon. I had a problem that my external hard disk automatically disconnect yesterday and this afternoon too.

Btw,it is night in my country right now.

This problem happening this night and now it's getting worse. I just bought it yesterday.

I just tested it in my laptop about 1 hours ago and it worked fine (my laptop OS is same as my PC). After testing in my laptop, I try plug it into my PC but it won't detected at all.

What should I do? Please help.

At the very least would be more than helpful.

However if this Enclosure doesn't have it's own Power Source you need one. The Modern Note Books do not have a lot of Current Available at the USB ports particularly if they are allowed to go into Hibernation or there are Power Saving Features invoked to extend the Battery Life.

If you are unable to plug in a External Power Source get yourself a Powered USB Hub and use that between the NB and the External Drive. These allow you to draw 500 MA from each USB Port on the Hub without placing any load on the NB.

Of course if your Mains Power is marginal you do have a problem and will require a UPS to be fitted between the mains and the plugs for all the computer hardware.

As the drive has been dropping in and out previously the chances of Data being readable on it are remote.

OH BTW you should post things like this in the Question side of TR as that will get you a autogenerated message telling you every time that you get a response instead of the Once a Day Default notification that you get in the Discussion side of TR.
