How come I cannot access my external USB hard drive?

by on December 29, 2010

Q: I have a LaCie 750GB Hi-Speed USB 2.0 external hard drive. I cannot access it from the desktop, start or from the folder. I have checked the partition and it says “Disk 1, LaCie (F), healthy”. I have tried to update the driver and got the message that there is no further update. The LaCie folder is in my C drive. No installation CD came with the device – only a “1 Click install wizard” . I have tried removing and then reinstalling via this wizard, but to no avail. Any suggestions? I am running Windows XP SP3

    So when you go into “My Computer” do you see the F: drive listed?

    Try rebooting your computer.


    Yes, of course I have looked for the F drive and it is there. Rebooting does not work.


    This is a brand new drive correct? Have you formatted the drive from the Disk Management screen?

    If you have, please post a screenshot of what you see in Windows Disk Management.


    Hi Mark,
    thanks – It’s an old drive, not a new one. The problem actually isn’t accessing the drive contents, it is getting the drive to perform a back up. I can click on the back-up icon but nothing happens, and no activity is apparent in the task manager when I try to do a back-up.


    Okay, so the drive is perfectly accessible. The problem is your backup software isn’t working. Thanks for explaining.

    What backup software are you using?


    Hello Mark,
    It is the software that came with the device and is called LaCie 1-Click Backup Software, as far as I understand.



    My best suggestion is to switch to some better backup software. I usually suggest to avoid software bundled with hardware as it usually isn’t all that great.

    My suggestion would be for you to take a look at you can use their software to backup your PC to your external drive for free. It’s also going to probably offer you a lot more functionality as well.


    Hello Mark,

    I will try this sometime in the next few days.
