Hello guys, I am not sure if I am writing in the right forum, but here is my problem and hope you guys can help. I have a toshiba canvio 1tb USB3 that is plugged into my retina mbp. The system tells me that it is recognizing the HD as USB3 and the speed is Up to 5 Gb/sec. I ran the BM Speed Test and the write/read speed stays at 1mb/s. In other posts I found that the problem might be the format, but mine is not FAT yet Mac OS Journaled. So what can be the problem ? how can I go fix it ? The disk utility app says that the disk is working fine too. I transfered 210 gb of video and it took precisely 1 day and 18 hours. Please help ! Thank you !
