Lacie 160gb usb 2.0 not being recognised by PC USB

Use one of the rear USB ports. Mind you, my PC won't deal with it when connected to any IUSB port although it's fine when connected to the router. This is driving me mad...

if the Laptop recognises new hardware, then there is no issue with the laptop. you need to install the software and drivers required.

1. the usb connector in the PC may have a broken board contact needs soldering or replacement.
2. there may be a broken USB cord to the external usb drive
3. the electronic controller in the USB case may not be working.
4. A new case may be needed with a new controller.

You need the power from the 2 USB ports in order for the Drive to have enough Power.
Try moving the USB Ports to another Port or Flip Flop the 2 USB Cables.
Another option is to uninstall the unknown device. Remove the USB Cables, Uninstall Shut Down, Re-Start.
NOTE: Certain Ports on your System are USB 2.0 and some are not. Try to use the 2.0 port listed in the Manual... it will be faster and may carry the Power.

I have the same issue. I have 4 Simpletech Signature 250GB drives. They all worked fine at first. After about six months two of them started connecting at USB 1 speeds. It occurs on 4 different computers!!! The post about it being the computer assumes is wrong. How can it work fine for six months and then suddenly change. Also it occurs on different computers. I have submitted a tech support request with simpletech and will post the results.

First, remove the usb disk, then when the computer boots up, press F8 continuously. Run the Safe Mode and try to uninstall the usb software and driver.

did you check the jumper settings.

Hi,
If this is an External USB Hard-Drive, your problem is insufficient power provided by the USB Port.
1:- Try Another USB Port If You Have One.
2:- If you have a 2 into 1 USB Cable, connect 2 into 2 individual USB Ports ( On Computer ) And 1 into Hard-drive Unit.
If none of this works, your drive is faulty.

What system is the laptop? File differences is the ext-hard drive FAT32 or DOS? Therefore XP [NTFS] is not 'seeing' its content. On the XP machine go to start/Control Panel/Admin tools/computer management/storage/removable storage/and check the file type

Open Administrative tools, Computer management applet; under storage, disk management. You will probably need to partition and reformat. If this drive is used only on XP machines, then format NTFS, otherwise FAT32.
