Non detectable external self powered 40 GB USB Portable Hard Disk

I have an external TrekStor 40GB self powered USB portable hard disk. The problem is that it appears as if it is not detected by the computer after plugging it in. I cannot see it under my computer. So what could be the problem and solution.

Id recommend trying these following steps: Go to: Start - Control panel - Administrative tools - Computer management - Disk management. Here you should be able to see the 40GB hard drive. Depending on your situation you may need to create a partition, to do so right click the unallocated space and choose to create a partition. The default settings will be fine. Good luck!

Its is blingking red ang blue and say driver not recogniced

make sure the lead/s that attach to this drive have a secure seating and are not bad/faulty the light on only tells that its getting power it might not be getting enough power you might test the lead/s or
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again, sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
hope this helps

My portable hard disk is not detecting by my PC/Laptop. it's working on other PC/Laptop. and i also installed my hard disk also giving beep sounds.

The power supplied by the pc laptop on the USB is insufficient to run the hard drive.

If you have an external power supply option on the hard drive, please use that.

Maxtor Basics external portable hard drive not getting detected

Right Click on My Computer, click on Manage, go to Disk Managment, if the drive is available you will see it there. Check to see if it has a drive letter assigned to it, if not right click on it and choose Change Drive letters. Make sure you are on the external drive though, you don't want to change your C drive accidentally. It should pop up in My Computer.
