    FreeAgent Desktop 500 GB not detected by windows XP

  • Maverick8482 Oct 19, 2008

    Hi folks!
    My seagate drive (external 500GB) is just 10 months old. It worked fine for 6 months and all of a sudden my computer (and other computers as well) stopped recognizing the drive. For the past 3 months I've been getting lucky once in a while after I plug-unplug my drive for 3-5 times. But since yesterday I could not get it work even that way.
    This drive sucks.

    If anyone knows how to fix it, please let me know.

    I have a Seagate FreeAgent Pro external hard drive. I have had it almost a year. Yesterday I rebooted my machine. Since then, I have not been able to get the drive detected by my main computer or laptop.

    I have the same issue. I realized that after the drive cools down for a while, the computer will recognize the drive again until it heats up again.

    So each time it stops being recognized, I unplug the drive and set it next to a fan. After a while, I plug it back in and it works.

    Not really a long term solution. Not sure how to fix it. I'm looking for a different product now.

A bit late for a reply to this, but I finally found a cure that worked so I thought I’d throw it out there in case it helps someone down the line….
This worked for my XP (SP3) machine and is a bit technical. Do not attempt if you're not sure of what you're doing.

My drive is a Seagate 160GB (ST3160203UR-RK) with similar symptoms. I’ve tried ALL the “usual” recommendations to fix this - plugging into different PCs, different USB cable, going into Windows Disk Management (where none of those suggestions work cause when I right-click on the drive the only option I got was “Help”), etc, etc.

What fixed it for me was altering a byte in the drive’s MBR. Using MBRwiz 2.0 (freeware) at a command prompt (specifically “mbrwiz /list”) I discovered that my drive’s partition Type was set to “12-DIAG”. Entering “mbrwiz /disk=1 /type=0Bh” (that’s zero B, and substitute your own drive #) changed it back to the correct “0B-FAT32”, and viola! My drive returned with everything intact.

I have been using Acronis True Image 9.0 and have heard rumblings that these kinds of programs can mess up external drives. Can’t prove that this was the cause, but I’ll be watching it closely from now on.

Hope this helps

Once for mTTED, YOU CAN USE RECOVERMYFILES TO recover your files from the formatted disk, it should recover all files and then copy them to another drive, you cannot save/copy them to the same drive you are recovering from.

To connect your external hard disk from your laptop you need to enter the device manager and uninstall all USB drivers and controller situated at the bottom and then restart your computer. While you restart just attach the Usb cable of the hard disk.......

Enjoy ............

My pc and laptop not detect my Maxtor OneTouch III Mini External 100GB USB 2.0 Hard Drive R01E100 what can i do please help me soon as possible

Good Day Anantsharma8!

If your PC and Laptop can not detect your external hard drive, I do suggest you check its usb cable. A substitute cable will confirm if your current usb cable is faulty or has an open wire.

Most common reason why the external hard drive is not recognize by PC or Laptop is due to loose connection of the hard disk inside the connectors of the enclosure.

Anantsharma8, if you have a small precision screw, I recommend you open the enclosure of the external hard drive. Remove the front face where usb and power plug connects, then slide it out to expose the hard disk also. You will see two connectors. These are the ones that always loosen. Please disconnect both the connectors and then connect it again properly. Put the hard disk back, close the enclosure and try to connect again with your PC or laptop via usb cable.

Good Luck! I hope that it will soon recognize your external hard drive.

Have taken hard drive from desktop want to know how to convert it to an external hard drive for laptop

You need to purchase an USB hard drive case and insert the hard drive into this USB case. You need to remove the jumper on the hard drive or set it to master drive. Power up the laptop then then power up the USB hard drive and then connect it to your laptop's USB port. The laptop will then detect this as a new device and will show up as an external storage device.

External Buffalo Hard Disk 500 Gb model no HD-PF500U2/BK-AP not detecting when connnected to a laptop or a desktop PC

Check the usb port function in the computer bios settings and be sure that it is set to yes. Connect properly your external drive. If it has two wire usb connections, use both to obtain the maximum power that will be need by your drive.

320 GB transcend external Hard dics is not at all detected


First of all make sure that the USB port that you are using to connect it to your PC is a USB 2.0 port, and not USB 1.0.

Also if it came with an external power, connect it to the external power before putting on your PC.

This is because the voltage supplied by USB 1.0 is lower than that of USB 2.0 and therefore might not be enough to power up your USB Drive.

After making sure about this, power up your system, and plug the external drive, then Right-Click on my computer icon, select manage, then go to Disk Management Option.

On the Disk management option Page you should see ALL the drives installed on your system, including the hidden ones, so what you will just do is, try and locate the one representing your external drive, and right click on it. then select "Change Drive letter and Paths", and give the drive any new, unique letter (i.e alphabet) different from the ones already on your system, and click on OK.

This should make your external Drive to be detected automatically.

Hope this helps you out.

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.

Maxtor Basics external portable hard drive not getting detected

I have a Western digital model wd2500b007-rnn
and I cannot get either my PC or my laptop to recognize the drive. I isolated the drive to another computer with the same error. It says USB device not reognized. I also tried a different port. I have not tried different cables. Can I retrieve the old data on the drive?

Did you find a resolution for this? I am having the same problem. None of my PCs can recognize the drive. Formatting seems to be the only choice but I need to recover my old data first.
