#187428 — Supper slow USB disk

[Multipart message — attachments visible in raw view] — view raw

Hi everyone

I have an issue with the speed of my USB3 Trancend disk, while I am using my motherboard with USB2 ports (and also
some usb1 ports). It seems it is using usb1 driver for my usb disk, and
because of that, I am expericing a very slow speed. I have to mention
that using an Ubuntu live CD I can have the normal speed. Any kind of
help would be really appreciated.


here is the output of my `lsusb`:

Bus 004 Device 002: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter

here is the output of my `lsbusb -t`:

and this is the output of `lsmod | grep hci`:

It seems pretty clearly to be operating at USB 2 speed. Are there any 
error messages in your dmesg output? Can you quantify the performance?

So this is your card reader

This is the flash drive

And the card reader is resetting every 30 seconds. Can you either unplug 
the card reader or move the flash drive to the bus where the wireless 
adapter is located to see what effect that has?

​That's what Nautilus show while copying a movie to my disk.​

​but to make sure, I tried using dd to have a better measurement:


$ sudo dd if=/dev/zero of="/media/mostafa/Transcend2/largefile" bs=1M
count=10
10+0 records in
10+0 records out
10485760 bytes (10 MB, 10 MiB) copied, 15.6461 s, 670 kB/s​

​I removed card reader and changed the port of the flash drive  and still
the same.

I also noticed something in my dmesg log:

[    1.173522] ehci-pci 0000:00:1a.7: cache line size of 32 is not supported

can this be the reason?

Maybe this is something with my /etc/fstab? because I tried to change the
content. Right now there is no entry for my USB disk there.

The whole idea for changing the content came from the fact that my usb
drives were mounting as read-only for non-root users, so I tried to fix it
and no luck. So at the end I removed my entries for removable media.
I still have that very problem of read-only removable media for my user.

I have a directory named /media/joe, with joe:joe 750 permissions. I'm
reasonably sure that systemd originally created that, but if you have
an appropriate directory which was created with different permissions,
that may be a problem.

If I plug in an arbitrary extN or FAT USB stick, it is automounted
under /media/joe, and I have write permissions (as long as the extN
location does). I don't have any that are formatted NTFS, so I don't
know how permissions might map.

This is unstable, by the way, Wheezy has an incomplete version of
systemd and may well be using usbmount or pmount for automounting.
I think anything later than Wheezy ought to have systemd handling
automounting.

Thank you! Mine was mostafa:root 755, I don't know why it was `root`, I
changed it back to `mostafa` and now it clearly fine!
I have the right permissions and speed:

(I can run dd without sudo)

$ dd if=/dev/zero of="/media/mostafa/Transcend/largefile" bs=1M count=1000
1000+0 records in
1000+0 records out
1048576000 bytes (1.0 GB, 1000 MiB) copied, 50.4967 s, 20.8 MB/s​

On the whole, there is no need for entries for removable media
in /etc/fstab, unless you have some really specific need. The wretched
systemd handles automounting of removable drives in a per-user
directory.

If you do put removable media entries in /etc/fstab, you need to put
nofail among the options, or else boot will fail when they are not
present (my first-ever systemd gotcha).
