By: "after trying to remove all the usb drivers. the hard disk LED lights shows its connected but the drive was not shown up anymore under disk management." do you mean you uninstalled the USB controller?
Does anything show up under the "unknown devices" tab? Its a yellow symbol with a question mark on it.
Is it the same cable that came with the external HD? If its not, might be a power cable just for USB. Needs to be a data/power cable.
Same thing happens to a smart phone when you connect it to a computer to use it as an external HD.

Is this USB drive a double Y type USB cable connected drive? In other words does it have power cable as well as data cable? When the USB drive gets not enough power then you can see the problems like yours.

this is USB drive connected using only data cable. yes, had tried to reinstall the usb controllers drivers

shreedhar, had tried to uninstall the usb device from device managers, after which when tries to find the device again, it gives the error, device driver software not successfully installed, USB mass storage device failed and show exclamation mark. the external hard disk is a IDE

motnahp00, your method is to try to reformat the disk? would like to retrieve the data if possible.

the driver exclamation mark is gone if i plug the device to a USB2.0 port. earlier the error occurs if plug to a USB3.0 port. now USB mass storage device is shown up under device manager but i can't see the drive under disk management.

Does your drive have the power cable input?

noxcho, the casing comes with a 5VDC connector.. but i don't have those power cables to test it, normally connected with just the data cable.. will try to test out with another casing.

The best test is take the drive out of the case (if it can be open easily) and connect the drive directly to free SATA port in your desktop. This way you will narrow the problem to its bottle neck. Either HDD is faulty or the case is the problem.

changing to anothe casing also can't detect. another hard disk using the old casing no problem in detecting. seems like its the original hard disk that is not detecting.

What about connecting the drive directly to motherboard sata port?

grnowAuthor Commented:
noxcho, you mean to put the hard disk back to the laptop? don't tink the hard disk is bootable, contains only data.

noxchoGlobal Support CoordinatorCommented:
No. As far as I know this is external USB drive. And if you have PC (not laptop) then it would be nice to connect this HDD from USB enclosure directly to PC mainboard using one of the free SATA connectors. And then try to initialize it or data recovery. This way you can see if the problem is in HDD itself or the USB enclosure.

noxcho, this is a 2.5" hard disk. can't test it by connecting it to another sata port.

2.5 Inch drives do have actually SATA interface. And you can connect them to the same SATA cable that you connect the normal 3.5" drive.
Or is your drive with IDE interface?

Normally motherboards have IDE connectors if the mobo is not completely new. Check yours - maybe you have IDE cable as well.
