[Bug 541937] Re: Copying files to USB flash drive is extremely slow

 

I got a similar problem, but not sure it's the same. My external USB HDD
(Iomega 320GB USB2.0) is automatically mounted on /media/disk-1 at my
Ubuntu10.04 startup through /etc/fstab:

proc                /proc           proc    nodev,noexec,nosuid 0       0
/dev/sda1       /               ext4    errors=remount-ro 0       1
/dev/sda4       /home           ext4    defaults        0       2
/dev/sda2       /opt            ext4    defaults        0       2
# swap was on /dev/sda3 during installation
UUID=a1a3d3a1-6a3c-4f16-9015-8bd1876fa89b none            swap    sw              0       0
UUID=51165527-e547-4bea-ac72-83c8290826f8 /media/disk-1   ext3    rw,nosuid,nodev,uhelper=hal 0 0

Every monday, I'm starting up my Linux machine, taking care that the HDD
is powered on before powering on my PC. This to ensure HDD is ready when
Ubuntu needs it. Indeed Ubuntu startup is very fast now. HDD contains
two partitions (ext3 and NTFS):

$ mount | grep sdb
/dev/sdb2 on /media/disk-1 type ext3 (rw,nosuid,nodev,uhelper=hal)
/dev/sdb1 on /media/15388EE8577DA058 type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096,default_permissions)

Nevertheless startup message tells me that /media/disk-1 cannot be
mounted because drive is not ready/present. Then after few seconds, it
disappeared, and loggin screen pops up. It has been properly mounted but
accesses (writes) are terribly slow. I restart my machine without
powering off my HDD and everything got back to normal performances. As
long as I restart, performances are ok. If I shutdown, next reboot will
be terrible in terms of external USB HDD performances... I haven't made
many logs but can get some on demand.
