Windows xp will not recognise the seagate freeagent desktop drive

My seagate freeagent desktop drive has been working well until this morning when I got the following message - "USB device not recognized. One of the usb devices attached to this compter has malfunctioned, and Windows does not recognize it." When I go into the device manager 'f' drive (my freeagent desktop drive) does not exist and in the Universal Serial Bus Controllers it is referred to as an 'unknown device' with no driver. I tried the desktop drive on another computer and it worked so I it is not the desktop drive - just my computer. For some reason my computer has suddenly decided not to accept the drive. Any suggestions?

    Thank you for your prompt reply sandrew.

    I did try other usb ports - you are right - no change.

    I removed the usb connection and went into device manager as you suggested. It is here that I get confused. When you say 'select the usb controller' do you mean the heading 'universal serial bus controllers' or do you mean search in that area for the usb that previously came up as 'unknown device'?

    When I remove the seagate usb the label 'unknown device' disappears.

Assuming you have tried other usb ports and had no change,remove the usb connection, then go back into device manager and select the usb controller, right click and select delete as this will erase any input driver the usb port recognises. Restart the pc and then the controller should be reinstalled automatically as it sounds as though the controller has become corrupt for some reason. Go back into device manager and check there are no exclamation marks, reconnect the drive and see if it's recognised.

    Yes, sometimes the usb controllers can get a little confused, by uninstalling them any peripheral plugged into them is forgotten if you uninstall the usb controllers themselves, because either the unit is faulty, which you know it isn't or the usb ports are playing up, this is caused by a drop in the power that is supplied to the ports to recognise hardware.

Assuming you are using a Windows operating system, you can just plug it into your computer's USB ports, and the computer will recognise it as another hard drive.

Double-click on 'My Computer' and take note of what drive letters are there (C:, D:, etc.) before you plug in the Seagate Freeagent.
Plug in the Seagate Freeagent. You'll see the new drive, likely E: or F: (depending on what is already there before you plugged in the Seagate Freeagent)
Double-click on the new drive, and it'll open up and you'll see the files stored on that drive. You can drag and drop files and save to this drive like any other folder on your computer.

I have window server 2003 OS and 500 GB free agent desktop USB hard disk is not showing in my computer. So how can i rectify it?

I just finished a Chat exchange with Seagate Tech support. MS Server OS's are not supported for FreeAgent devices.

It appears that whatever drivers exist in the XP install that recognize the USB device connection are not the same in the MS Server environment.

I plan to check the USB device drivers from both systems and see if the XP USB device drivers will work on Server 2003.

Freeagent with server 2003 not working

Seems that Seagate did not release a version of software which could be used on a Windows Server 2003 platform. I checked their web site at the following link & didn't find any software supported on Windows Server 2003:

Sorry, but I can't help you with this one. Try contacting Seagat for this & see if they have a solution to your problem.

Seagate FreeAgent external hard drive 500GB not recognising directory tree

Its the rubbish software that Seagate have bundled with their drive which will not allow you to backup the system folders. Solution is to use another backup utility, a google search will quickly locate numerous FREE software products which will alow you to copy anything. Unfortunately when you start googling about this drive you may be quite distressed about your purchase, as i have been :( Problems lay ahead with this drive due to inadequate cooling.....
