Either on the actual computer, or between the computer and external harddrive, or even the external hard drive and itself, its transfer speed has dropped dramatically. Granted, it is a laptop, but i use to get speeds as high as 100 megabytes per second, but averaged around 70. Now, after restarting my computer, i am lucky to get 10 megabytes per second. I tried defraging. Does anyone have any idea why or might possibly be able to help me out? Thanks in advance for the help.
