Fedora 13 copying data very slowly to external HDD

n03x3c · 06-23-2010, 01:55 AM

Hello all,

I have Western Digital 1 TB external HDD. I had slackware 13 and it could copy data to it with speed around 30 MB/s (copy from machine to HDD) and it was cool. It's usb 2.0 as KInfoCenter says. But now in fedora 13, it's like 1 MB/s or even less (KInfoCenter still says usb 2.0). I am mad... brrrrr

Any special mount option to set in fuseblk to speed it up? I mean something like blksize or like that?

Code:

/dev/sdc1 on /media/My Book type fuseblk (rw,nosuid,nodev,allow_other,blksize=4096)

Can you post the output of:

Code:

#lspci | grep USB

Also, consider installing fxload which downloads firmsware for your USB devices to enable USB high-speed.

There are several simple things you can try.. all documented many times on the net already.

Unless of course there are *issues* with fed..

If you are using ext4, there are several *tweeks*, depending on your needs... or it can actually be slower than ext3.

For instance, there are *trade-offs* (ie. good & bad things) to consider when altering the file system... no 'barriers' is one.

Read the man pages of mkfs.ext4, etc.

HdParm might help.. I suppose when you upgraded.. the old settings were lost.. and maybe hence the decrease in speed.

But it sounds like there is something *major* wrong however (not dangerous tho), because of the numbers you are claiming (1 MBs).. is too drastic.

Lettuce know..

n03x3c, did you ever find the culprit?

Don't know why but it's working now. I think fedora got it's firmware driver by itself or something similar...

Here's lspci output which says my machine has USB v2.0

Code:

00:1d.7 USB Controller: Intel Corporation N10/ICH 7 Family USB2 EHCI Controller (rev 01)

Anyway, thank you guys.
