[SOLVED] Problem with usb hdd

[Ivan Tuzikov]

My usb disk suddenly works very slowly. Copying operation from system hdd to external usb hdd shows speeds of about 1 MB/s instead of normal 60-110 MB/s depending on the content. I've checked disk with HDDSCAN. What does the error means and what options do I have? P.S. External drive contains collection of movies and I recently started to use it as main drive for torrents.

The SMART report looks clean, but obviously something is wrong. Your transfer rate is what you would expect from a USB 1.0 connection.

I've reconnected external drive to another usb3 port. Speed is normal again. Probably, USB port malfunctioned due to the age of the motherboard (Intel DH77KC, Core i5-3450, bought in May 2012 - still operating), may be some capacitor on MB failed or maybe there is short-circuit at faulty usb port, because my Al chassis is slightly deformed during years of components upgrades and replacements.
