Hi Pavan,

I am not very sure about why the utility is not working for your 8Gb Flash.
If I remember correctly, Internet connectivity is required for the utility to work.
I had re-uploaded it to "http://www.esnips.com/web/USBfiles/"
you can also try to get in touch with the "Transcend support" they are really helpful.

Hi Amit,
I have similar kind of issue with my 8 GB Transcend JF V30 Flash Drive, i have downloaded the tool and the manual, but when i run the tool a command windows pops up and closes. I am not getting the screen which is mentioned in the Manual. If i try to run the tool from the command line it says "Program too Big to fit in Memory" Please let me know what can be the issue.
Is there any other way to download or run the tool.

Thanks & Regards,
Pavan Ram.

Hi Friends,

Please find the utility which will help you to recover the trancsend Flash USB drives, if gone bad.
All you need is the Valid Serial No of the USB flash drive.
Refer the Link to find where the Serial No could be for your drive.

i have the same problem recently..i one day thought of wiping the transcend 4gb pen drive and see how it goes..it took a lot of time and i cancel the wipe then after sometime pull it out..then the next time i use it i got greeted with the same error message that you got..

Thanks to all who had replied to the thread. I had been in touch with the Transcend guys for the same and they provided me the steps to get my device back in shape.
You need to have the serial no of the device handy for that.
This will make the device as a fresh (formatting low level) thus all your data would be lost.
Do let me know how can i upload that utility here.

have u used windows disk management utility??
