The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

USB HDD not working.

Asked by bencypg in General Computer Systems

Tags: usb, hdd, detected

I got a USB HDD one week back and I tried to plugin to the Desktop at work and it does not detect this device. Plugged into the laptop and it shows Unknown device.

I got doubt that the drive is problem but it works perfectly at my home system with XP SP2. All system that I tried are XP SP2. Tried on defferent desktop system at office and it works fine. This USB HDD does not work only on two systems (Desktop at office and a laptop).

Then what I did was I uninstalled the USB 2.0 drivers and as soon as I uninstalled the system detected the Mass storage device and it worked fine but it worked slowly as there were no drivers. As soon as I install the USB 2.0 drivers the USB Hdd does not work.

So, I tried a lot to find out what is wrong and after much research on registry I found that there is a ID for this USB Mass storage in the registry. I copied this id from registry on the system where it works fine and imported them to the Desktop at work.

Now, the USB Hdd works fine on my work desktop without any problem with the new id entered in registry.

Now the problem is that the laptop does not detect this USB Hdd. I have tried the registry method but still it does not work. Today I have formatted completely and installed SP2 and still it does not work. Laptop USB is working fine as all other devices work on all the USB ports.

The registry key that I copied is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Enum

0 reg_sz  USB\Vid_04cf&Pid_8818\100

Can anyone help me with this problem? Why are these two system not detecting the USB HDD when other system with similar chipset and OS are working fine?

I know that the system is not problem nor is the USB HDD. Something to do with OS and the USB drivers.


Second problem is that the USB HDD works fine on all other system with XP SP2, after some time I get message "Delayed Write error" unable to write to the drive. This comes on all the system having XP SP2. I have tried disabling caching the drive but that does not work. Thank you
