Slow USB hard drive write
Due to a hard drive crash I needed a new backup drive and got a USB 1TB iomega prestige. Then, when I tried to copy my stuff, it just took forever. At first I thought it might have something to do with it being NTFS (although my other hard drive runs NTFS as well), so I formatted it with ext4. Still the same problem. This slow writing speed basically renders it useless to me as it would probably take a week or so to back up my stuff.
Here are some copy times for an example video file of 246.50 MiB, where hdd is my laptop internal drive, seagate is my old external USB NTFS drive, and iomega the new one:
hdd (sda) = ext4 - 111.79 GiB
seagate (sdb) = ntfs - 465.76 GiB
iomega (sdc) = ext4 - 931.51 GiB
seagate >>> hdd = 0:08.5 min
seagate >>> iomega = 4:25.2 min
hdd >>> seagate = 0:07.5 min
hdd >>> iomega = 4:06.4 min
iomega >>> hdd = 0:08.7 min
iomega >>> seagate = 0:09.2 minI tried different ports (all 2.0 and all directly going into my laptop) and apparently it's got nothing to do with that.
Attached are some outputs I collected. I tried to look up those error messages here in the forum and through google, but couldn't really find an adequate answer/solution. So I'm hoping that one of you guys might have a pointer for me.

Re: Slow USB hard drive write
I'm getting similiar issues with my extern drives. It would take forever for the kernel to recognizes the drive and partition and then when i tried to mount and read/write, it would be very slow. When i check my dmesg, it would have similiar message as yours.
So far i have been able to solve or track down the issue to get it fix. I know it's not my usb ports as it works perfectly fine with my USB2.0 flash thumbdrive, but when it comes to external drives i'm facing this issue.
Anybody know what is going on with our issue?

Re: Slow USB hard drive write
Hi, I'm having the same issue and I can't seem to find a solution anywhere? Incidentally, can anyone tell me how to kill a nautilus-copying processes? I was trying to copy ~20GB earlier. After 7GB the progress bar got stuck and now when I ls /mnt, my entire system goes deadlock.
Also unmounting my USB device as root seems to enter a deadlocked state... Rebooting/shutting down also enters a deadlocked state. The only thing I can do is unplug the device mid copy-process, and that can't be good, right?
