Detailed help

This instruction is only for Kingston Data Traveller 5000 flash drive.

Regardless of what is stored on the flash drive, do not use the drive on computers if you are not sure of their administration; this includes public computers at libraries, internet cafés or at your friend's house. Your password might be compromised without you noticing, and some time later the flash drive with sensitive information on it might go missing.

Never save both public and sensitive material on the same flash drive. You should also never use the same flash drive for multiple purposes, such as saving both personal documents and sensitive research materials.

Encrypted flash drives are not under the University's central administration, so IT support is unable to access the data stored into their memory or help with forgotten passwords. The password on a Data Traveler 5000 USB flash drive can be entered wrong 10 times, after which it is locked down and the information on it is permanently deleted. It is possible to restore the flash drive back to use, but doing this will delete all data on it.
