Question

Write-Protecting USB Flash Drives

Is there a flash drive product on the UK market that contains security software that will prevent files being written from a host computer to the flash drive without the user's agreement? The objective is to keep the flash drive free of malware transferred from the host.

Answer
NO.

Because I could be on my ChromeBook, Android phone, Linux or Apple no software approach can work across all computers.

If you want read only sticks, these are available. Sorry but since these are found with a search I won't link to them.

PS for Windows only.

Look at the read only partition idea. It may be possible to create two batch files to say "lock and unlock" that partition.

My bet is the user would unlock it and never lock it again.

Read Only Flash Drive

Thanks for your advice. The user is not tech-savvy so a hardware-switchable device sounds like the best option. Not perfect as you say, but I guess it will reduce the risk of infection to a much lower level than using a permanently writable device.
