I have brought 3.5" External

You don't need to have a driver for your external HDD to work.

You have three possible problems:

1. USB port (software problem) - outdated USB driver or with bugs

Try updating them via the device manager. Or you can try uinstalling it then scan for hardware changes. It will automatically reinstall.

2. USB port (hardware problem) - try a different USB port.

3. HDD defective - You may want to try connecting it to a different computer. If it doesn't work in a different computer then it should be defective.

Hi ,
Try Disc Manager from Samsung . It works fine with internal drives but should also do it with your external one :

Hi,
Have you tried uninstalling your seagate free agent software, restarting your computer and installing it again?

Recomendation: Replace for a external hard drive, The Zip drive is outdate. With theExternal HDD you gona have more space than a Zip drive, really much more.

Hi
try to check your hard drive on other computers and see if you could access your files or not.

1-other computers can detect your HDD:
1-1-software issues on laptop:
try to update windows or OS of your computer for most updated driver
1-2-hardware issues on HDD:
1-2-1:you have a broken/shacked/shocked/stroke HDD:
go for replacement or warranty service.
1-2-2:USB/fire wire cable problem:
replace it
2-3:you have a damaged/weak USB port on your laptop that couldn't fully supplied the minimum needed current:
repair the damaged port via certified expert or manufacturer warranty/repair service.

2-other computers can not detect your HDD:
2-1:cable problem
2-2:you have a broken/shacked/shocked/stroke HDD:
go for replacement or warranty service.

best regards

Due to the nature of the problem you describe, it appears that you could be experiencing an issue with the hard drive and/or the external USB case. Below I have listed 2 possible solutions to help resolve your issue.
A. External USB Case 3rd-party Driver
USB cases (depending on manufacturer and/or OS) will sometimes require a device driver to be loaded before the device (in this case, an external hard drive) will function at its maximum potential. From Windows XP and on, this has not been the case as the OS will provide its own driver but if you are using an older OS, this maybe required. If the external case brought a driver CD, perhaps installing could shorten the time to access your data on the drive.
B. Hard Drive Corruption/Failing
When a hard drive has become corrupt or is failing, the device tends to become sluggish and overtime completely unresponsive. When this occurs, the best solution is to backup your data as soon as possible and replace the failing hard drive before it dies completely and you cannot retrieve your data.
This is a common scenario and unfortunately, due to the manufacturing process of hard drives, the inevitable end to all hard drives once they have met their end of life.
SSD (Solid State Drives) are hard drives that are not manufacturer using metal platters but rather flash memory (such as that of USB flash drives, digital camera memory and cellular phones). These drives feature no moving parts, hence their failure rate is extremely low. Also, their lifespan is typically rated for tens of years with some industrial products rated with lifetime warranties and are able to withstand drops, falls and extremely low/high temperatures.
The trade off on HDD vs SSD is the cost, with HDD prices hovering around $.30-.50 per GB while SSD prices (while falling) are still around $1-4 per GB.

You can get a new external case for $18 off ebay. It is a simple operation to change the drive over to the new enclosure. This might be an easier and cheaper option for you.

You can use either.

You can also use external portable hard disk, you can move all your software and stuff to it.

Better would be installing a new operating system to new hard **** with larger capacity, it will make your system fast.

You can also fit hard disk in your computer PC cabinet, you will just need to set it as "Slave" or secondary hard disk, to do this, setting is available on the hard disk.

Hi, Initially, allow Windows to install automatically drivers or needed configuration, then perhaps you need to reboot. Thereafter check if it can be seen in My Computer, otherwise, pls post back for any messages or errors. Good luck and kind regards.
