The same problem here. External TOURO Mobile 1TB disconnects and reconnects all the time. Dualbooting and using it in windows works fine.

From The Drive Status in “gvfs” package in Ubuntu: Confirmed Bug description: Receive this error in the error log when reading from the drive - kernel: [18057.860057] usb 1-3: reset high-speed USB device number 18 using ehci_hcd I have tried deleted all the partitions. Created a 350GB EXT4 partition. Copied a 700MB file to it no problems. Tried copying the file back off the drive to the laptops drive and the problem re occurs. Therefore, this bug is when it reads from the drive rather than writes to the drive. It also appears I need to do the following in order for the drive to stay mounted - sudo echo 5 > /sys/module/usb_storage/parameters/delay_use What is interesting is if I leave the drive on after it has this error and disappears off the USB Bus, I can hear the drive....sounds like the heads are contractually trying to read the disk. Turn the drive off and on again, the drive mounts without problems - Dec 23 14:05:23 coralreef kernel: [20176.476132] EXT4-fs (sdb1): mounted filesystem with ordered data mode.
