I brought this because my hard disk which was using was corupted.dell is very good for making electronics .but this time they made very good hard disk it function very smothly .it doesnt get corrupted .so chances of memmory loss are very less I droped from 20feet still it was working very fine.i think more than three colours are available in this so you can select your favourite colour.dont put password to it .i think if you forger your drive is locked .dont connect it to public computers as it may get viruse.i would like to say please dont remove it from connection when it is running go to my computers disconnect there and than remove .at last it is nice device
