The HP digital photo frame that I am working with recognized the thumb drives in the usb port, but not the 500 gb seagate external hard drive that I want to store photos on. The thumbdrives are formatted with fat32 and the seagate is ntfs. Any suggestions.
Though, the main of the two points have been spoken about, there is something more that I do have a doubt about, there are certain digital frames that is capable of accessing a storage device with particular amount of storage space, so it may be that the huge storage device might be causing the problem. Hope this was of some help to you.
