My OS is Windows 7 Home Premium. I am using Kingston Data Traveller USB 2, 8GB, Model G3. Mainly used for storing short videos, pictures, and documents. There is no problems with the items already in the USB. Everything opens and videos play. All new items, copying from the computer to the USB, functions properly. When I open the copied items everything opens well and the videos (all types), play in VLC player. When I eject the USB and remove it from the computer, something happens to all the new items. When I insert the USB again all photos, are corrupted. They open greyed out or with different colours splashed on them. All videos are corrupted. Either the player is unable to play them or if playing, the picture fragments into pieces. pdf. documents don't open, with Adobe Reader notification, saying "document corrupted or........". For some reason docs. and txt. documents open without a problem. I have checked this matter using another USB drive and it works fine. I always remove the USB using the "Safely Remove Hardware" notification. What can I do? Thank you.
