USB Harddrive is Painfully Slow After Upgrading to 12.10

[varunendra]

Honestly, I was planing to ask you how to do it in my last post

Nice to know you were interested, because that's the key to learning all the stuff we keep dealing with here

One last question before I leave for a long (maybe a few hours, maybe a day) break, what architecture of 12.10 are you using? 32bit or 64bit ?

I've just finished downloading 32bit iso, so may try it on a USB or in a VM. But if you have 64bit, I'm afraid it's going to take me about a couple of weeks to download it @ my crawling GSM connection speed !!

Better post the outputs of -

uname -a
lsb_release -d

I'm using 64bits but I don't know which architecture DBQ is using.

Try to install usb-modeswitch from synaptic if its not installed.

[DBQ]

usb mode switch is already installed. I am still having the same problem.

Try to monitor the read/write activity with

sudo iotop -o

It's in the repos, simple to install.

And, could your problem be related to that of this link?

iotop shows transfer speeds similar to speeds reported by nautilus.

Any other ideas? It definitely looks like a kernel/NTFS driver -related issue. It worked like a charm till Ubuntu 12.04.

I wonder if anybody else was ever able to resolve this.

Because of this issue, I had to resort to using Fedora many times. I cannot simply format the drive into ext<X> (as such systems give the correct speed) because I need NTFS in order to share my data with other machines.

I think that 12.10 is not mature yet, and that it is a bug. I will continue with 12.04 (which is also an LTS release). If there are features in 12.10, that you need, I suggest that you use some other file system for your USB harddrive, for example ext2, ext3 or ext4.

These file systems can be mounted by Windows, if you install a driver program. See this link

[DBQ]

This is not an option.

I wonder if there some mounting parameters that could be the cause.

This issue seems to be gaining a wider notoriety, although no real solutions have surfaced.

Is it an option to go back to 12.04?

I don't know, but I think it is a bug, not bad parameters or lack of parameters, since it used to work.

Yes, and there will be a bug fix, but we don't know when.

[DBQ]

It's been a while. There have been many kernel upgrades released.

However, the problem persists.
