Few other bartpe beaters out there, I like geeksquads MRI very solid reliable Fmod Explorer can copy files like its unstoppable copier but even more reliable and fast and u can format drives still as well as run a few other nifty tools.
Theres powermix another top fav, hawkpe a good un as well and up to date with the latest sata drivers. My old time fav is Minipe which is like powermix but more up to date with sata support and more up to date software. One thing too note is to date only the GeekSquad MRIPE has usb refresh support, so u can plug in USB devices and detect on fly the other PE copies dont have that support from what ive seen.
