I plug in both usb connectors, and nothing happens. Device does not appear on laptop. Pinfarina 160GB, red case.

USB hard drive is a portable external storage device that works just like a conventional hard drive. The device is simply plugged into a USB port on your computer as you would connect a flash drive. Unlike a flash drive, however, a USB hard drive can store a much larger amount of data. If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.

Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely. Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7). The USB device should be listed as "removable disk" once it is plugged into the computer. If it is not listed among the available drives on your computer, proceed to the next step. Ensure that the data cable is working properly. Try another USB cable if you have one available. Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive. Reboot the computer if the USB hard drive is still not recognized. Plug the USB cable into another USB port and check to see if the device is detected. If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port. If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem. Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager." For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter." Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives." If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears. The external hard drive may have been detected but the device is not working properly. If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced. Hope this helps.

If your computer or laptop has a problem detecting a USBhard drive or a USB device, and another computer can detect it, then theproblem could be a RF interference problem. Try using an USB cable that is a shielded USB cable (ie. AnUSB cable that has a clear plastic covering and you can see a metallic weavewhich covers the wires) OR a USB cable that has a Ferrite core attached to theUSB cable (the ferrite core is a cylindrical object approximately 30mm long X15mm diameter and it is attached to the USB cable near the connector).

Your assumptions are leading in the right direction.

• The blue light would just be denoting power to the device the red light would denote drive activity. The limitation on this enclosure is that its white papers states a "Hard Drive Compatibility: 320GB HDD capacity", but I have seen people use a 500GB drive that seemed to work. If your using a drive larger then 320GB this may be an issue.
• The enclosure HDD combo is Plug-N-Play via USB so this would mean drivers most likely are not the issue. I don't believe drivers are even packaged with the device which would mean they use protocol standard drivers from the OS.
• Make sure that you are not hooking the USB up to a external USB hub (especially a bus-powered one) while trouble shooting as it may not provide enough power. Connect the drive up to system USB controller directly while trouble shooting.
• I believe this device has the ability to hook up 2 USB cables at the same time for extra power (mainly while using the eSATA connection). Try hooking up the USB mini-B connector and the USB +5VDC connector and then hooking both up to the system on two different USB ports. This should then correct the possibility that your drive may not be getting enough power.
• Lastly, the enclosure could have a faulty IC on the PCB. Exchanging it would provide the answer for that.

The first thing you should do is plug your USB drive into another computer to see if it works on that computer. If not, the drive may be bad. Does the USB connector end look bent at all? If so it may not be making the connections, and straightening it out should fix the problem.

If it shows up as a USB mass storage device it:-
1. Has power
2. It is connected to the computer via USB.
3.The correct software has been loaded for the hard drive. 
The beep sound is probably an error message saying that the drive is not responding properly inside the case.

Hard drives Drives have been known to stick or not start up due to power cables or ribbon cables being dislodged. Try pushing these back into place.

If this is not the problem go to the Maxtor site (maxtor.com) and report the problem with the drive, not the USB which appears to functioning correctly.

The battery is drain.

DO NOT use the USB cable to charge your Blackberry.

When the PC/Laptop/Mac go to power saving/SLEEP mode it will cut off the charge to the Blackberry.

Use the official AC charger to charge the Blackberry.

Make sure the AC power is not switch off to the power pack at night.

The mini USB connector can be loosen over time.

Plug in the cable and check for connectivity.

Attach your external HD with some other computer, that will definitely appear normal, the problem is due to a virus in ur HD. Your computer's antivirus software stops it to appear. Back up your data on the other computer, format ur external HD, remove un-necessary files and run a virus scan to the files u copied from HD, Hope this will solve the problem, if not, let me know and tell me what would be the response on the other compuer

Dear,
Please check this drive with another new cord to connect it with PC.

You'll want to verify your computer recognizes your usb ports.
In device manager, look to see that you don't have anything with an exclamation mark, question mark, or red X on it. Make sure you have the usb ports listed under Universal Serial Bus controllers. If nothing shows, your usb ports may be dead. Depends on the age of your computer and what might have happened to them.

Device manager- right-click My Computer and go to properties, then select the hardware tab.
