Pendrive not working

Hi Guys,

maybe somebody had the same experience, and has a solution for this:

I have an 8GB Kingston DataTraveler pendrive. In the other machine (with XP) it works fine, but on mine (Win7 Home Premium 64-bit) it behaves very strange. When I want to copy anything to it, copying data to it is very very slow, and most of the times the drive just disappears during the copy (eg. after ~1MB from a file that is 700MB large). I can say that I simply can not copy files under 1-500Kbytes to it. It is really frustrating as other pendrives (other Kingston ones too - that is 1GB) work fine...

Here's what I tried to fix it:
- Format it (on mine, and on other machines too; quick and full format)

- Run Checkdisk with advanced options (full scan and fixing sectors)

- Remove, then reinstall the driver

- Change the Policies to Fast writing from the default quick removal

- Scan with Malwarebytes if Norton did not got anything, but everything is clean

 

If you have any idea, let me know please.

Thanks
