Solved Twinmos Pendrive not detected-win 7

[Kamrul08]

I have a Twinmos X2 Premium 4GB Pendrive. It works fine on XP. But Win 7 can’t detect it. When I insert it, Windows shows notification in taskbar without Drive letter or name. I added some screenshot below.

Hello Kamrul,

With the USB flash drive connected, you might open Devices and Printers to see if the USB flash drive may be displayed here. If so, right click on it, and click on Troubleshoot. Follow the instructions it gives you. If it finds a solution (ex: to install a driver), it may ask you to approve before it will.



Hopefully this may help,
Shawn

I tried it before. Now I tried again and included screenshot.

Does it show any errors under "Device status" for the USB drive in Device Manager?

Yes, It shows- The device is working properly. I tried to update driver but windows tell- Driver is update.

While in XP, you may need to backup what's on the USB, run a clean command on the USB, format it as NTFS or FAT32 again, see if you have access to it now in Windows 7, then copy the data back if so.

I would like to Thank you Brink. Your post is very important and informative. I didn’t apply clean command ever before. I decided to follow your most important advises. Result below.

My Disk is in Online position.

​

I applied clean command but it shows error like below.

I got the system event log like below.

​

[FONT=&quot]After Clean command my disk shows [/FONT]unallocated[FONT=&quot]. Then I created new volume and tried to format it. But Windows 7 can’t perform format process. Then I formatted it in XP.[/FONT]

You're most welcome Kamrul.

Does Windows 7 see and have access to it now?

No. Same result in my Desktop PC.

[FONT=&quot]I tested this Pendrive in a Laptop (running Win7). No problem there and the pendrive works fine. Then I performed Clean command in this PC without no problem as your advices. I think this the fault of my Pendrive. So let the topics finish. I thank you very much for very helpful and informative instruction.[/FONT] I am pleased on your advices.

You might run chkdsk on the USB flash drive to test it for bad sectors just to be safe.

Looking at the USB flash drive's website, it appeared to have security features that may have been the cause, but using the "clean" command should of wiped all that out.

Yes, Brink. I ran chkdsk command many times before and after clean command in xp.

At last I applied clean command in a laptop and it worked successfully. Then I inserted in my desktop PC again. Same result. I used alll usb ports for this pendrive in my PC. I am using Win7 Ultimate (SP1) with Intel original Motherboard.

Do you have the same issue with any other USB devices?

No. All works fine. I have another 3 pendrive (Apacer). I also use other pendrive. No problem I could find but Twinmos.

I bought another one Twinmos in 2010. After 1 year and 13days It stoped working. So it placed in dustbin. Then I bought it in January 2011. It also made me crazy.

My friend gave me same one Pendrive (Twinmos X2 Premium) yesterday. It cann't be formatted. I tried clean, chkdsk command. I used HP USB Format Tool, Twinmos format tools. but I couldn't success. So I understood Twinmos life is 1year.

I'm not sure what it is, but there appears to be either some issue with that brand of USB flash drive, or they have some type of proprietary feature preventing it from working unless you do something. Did you install of the required software for the USB from their site? For example, "Applauncher" and "UFDutility".

I tried it. These tools tell, The device is not plug-in. But my pendrive is connected.
OK brinks. Thanks a lot to help. You are very helpful. I don't hope to get it back. Let the topic finish.
