Problem with a hdd enclosure

I just bought a hdd enclosure which uses usb2.0. But it works on usb 1.1 too. But i have a problem is that when i switch on the hdd enclosure. The computer recognise that something is plug into the usb port and it start to install the hardware. Sometimes, it installed succussful, sometimes it doesn't. Most of the times when i go to the device manager, there is a exclamation mark beside the usb hardware section. Sometimes when it install succcessfully, there are no exclamation mark but the drive does not appear in the my computer there at all. I am sure that the enclosure is alrite because i tested it on other computers. Does anyone have a solution for it?

Some work ,some don't.
It depends on the system.
External USB drive converters are very tempermental.
Try to stick with name brands.ADS is allright,the Syba's suck.
I have even had issues with Sony's.

I suggest uninstalling the USB driver in device manager and letting it reinstall after rebooting.  Another thing you can try is a powered USB hub, which will act as a buffer to smooth out the USB signal.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You could try.There are simply some systems where the external cases will always be flakey ,regardless of what you do.
I have had 3 different manufacturers of external enclosures and some worked fine on some ,others no.
You may need to mix and match.

One thing, if you are connecting the usb case first and then turning on power .... I would turn on the power and let the drive spin up before connecting the USB cable.  The device may be momentarily unstable as power is being turned on, and this could temporarily "hose you" on that system, until everything was disconnected and powered down.

Ok, one other comment ... you mention a "1st time" and a "2nd time".  People know that you can "hot swap" USB, and they think that means that you can just "pull the plug" (the USB cable) whenever you want.  YOU CAN'T (or, at least, you shouldn't).  USB and PC Cards (notebooks) both have "hot swap", but you are supposed to "STOP" the device first, and not remove the device (USB cable) until you get an "it is now safe to remove this device" message.  You stop the device by using the "safely remove hardware" Icon in the system tray.  If you are not doing this, and you pull the device, you may be unable to use it again until you have restarted the entire computer.

Beyond that, as pgm554 said, sometimes some combinations of computers and USB devices are just plain flakey.  Sometimes it's the USB port, sometimes the device, sometimes the combination of the two, but, as they say,  "s**t happens".

watzman, like what u just said i should not unplug in that way and i did it. so i had just restart my com and wait till the hdd has run for sometimes before plugging in the usb cable. The drive did appear in my computer but when i double click to access it i got this error: "F:/ is not accessible. The file or directory is corrupted and readable"

That's a different problem, but you may have either a defective enclosure (it happens, and it's happened to me) or one that is, for whatever reason, incompatible with the USB ports in your computer.
