Drue Mc Laughlin: I have someone who wants to buy the new one for my birthday next month...my query is this , with the adapter for usb will it be able to read directly from an external hard drive? I presume I will be able to sinc it to my A77. In which case it should then be as flexible as a samsung 10.1. I have not as yet used the apple platform and have stuck to windows platform..feedback please
The USB adapter is intended for connecting directly to a camera such as your A77. It simply turns the camera into the memory card reader which is useful if your camera doesn't use SD cards.
Most external drives (including every thumb drive I've tried) won't work. Those that do work must be powered on it's own. The iPad USB adapter does not provide enough power to run most external devices. Furthermore, the attached device must be formatted in such a way as to resemble a flash card, usually FAT, FAT32 or exFAT formats. I don't know if it'll read any other formats. I'm not sure, but there may be further requirement to have the contents of the drive placed into a commonly recognized folder structure used by most camera manufacturers. Something with a DCIM folder in the path is pretty common. I'll admit that I haven't tried an external hard drive myself, but I have tried several thumb drives with no luck (the iPad doesn't supply enough power to even turn them on).
