You will receive Knoppix 9.1 loaded on a 16 GB flash drive, tested and ready to load. Knoppix is designed to be run off a disc or flash drive as its normal operation rather than being installed to the computer's hard drive.
Each drive is handled with the utmost care. Image files are obtained only from official sources and their checksums verified. The data written to the drive is also verified.
The drive itself has a silver metal body and a clear plastic cap. I thoroughly test drives from each batch I use to verify they are fully functional and meet their rated capacity (though keep in mind actual available space will be slightly less than 16 GB due to formatting).
