My friend's brother gave me his old laptop because it had a blue screen problem and he got a new one. So I now have a Dell M1210 which I just got and, though I haven't reformatted, booted into Backtrack 3 off my USB drive. I found out that I can use the wireless card in it to test wireless security like WEP since it supports packet injection which is awesome. However I also like using Backtrack 3 on a daily basis. I want to put it on a SD card so and just keep it in the SD slot so when I feel like using it I don't have to have a USB drive sticking out of the side. Can anybody recomend me a SD card that I can use for this? I really don't know too much about them since I have really never dealt with them. I just want a fast one that will work with my machine and that I can boot backtrack 3 from. Suggestions?
