With all the high technology that went in to creating the first thumb sized flash drives a person would think that someone would have considered just how vulnerable they are to losing the cap. I carry an Ultra FlyDrive with me everywhere I go, and on more than one occasion I have lost the protective cap that goes over the connector. Without the cap a flash drive is vulnerable to dust, dirt, and accidental damage so it is really important to keep the cap on it when not in use. For those of us that seem to lose the caps on a daily basis a company named RooKaps has come to the rescue with stylish and vibrantly colored replacements.
The RooKaps come in multipacks of four for as little as $6. Other options are available including caps that come already attached to lanyards. While the caps are cool, the lanyard idea leaves me worried. I would rather have a cap fall off of my thumb drive and be lost forever than my thumb drive fall off of the cap. They are also quoted as being made from an electrostatic disapative material, to help prevent data loss due to static discharge, but to my knowledge I have never seen this as a problem with thumb drives. Still, if you need a replacement usb drive cap these little caps will help keep the lid on your precious data.
