Hi, Due to some data protection laws my work has brought in, I'm in need of a password protected and secure USB stick that I can use on my home mac, but also on my work windows computer. The files themselves are just word docs/jpegs/movs/usual files, but if it was to be lost it needs to be that noone can open it without my password. They've given us a USB stick with password protection on it, that works on the windows laptop, but when I plug it into my mac it resets it and asks me to choose a password which is then not recognisable on the windows machine. Is this possible? It doesn't *have* to be a stick, I could use a small HDD instead, but I can't keep using my unprotected USB stick, and I can't switch to windows only or mac only. Is there anything I can buy/do?! If possible, I'd also like a way of backing up the stick but I'm not sure how. I currently clone it to my mac and that gets a further time machine backup but I can't keep doing that now. Thanks very much!
