I have been owning a buffalo 300 gig external hard drive for over a year now. I have been recently receiving wierd errors such as sudden disconnection with "hard drive not recognized error" from my windows while the hard drive is still plugged in. I think the hard drive has just crashed at that time. This error occurs quite often when moving large amount of files but it has not happened even when i tried moving bigger files before this month. Can some one tell me what the problem might be and a solution if possible? there are no data loss currently when crashed but i fear the possibility of that happening. Thanks so much guys, appreciate it.
