udisksvm and ultra-slow USB HDD write

I followed this guide https://bbs.archlinux.org/viewtopic.php?id=112397&p=1
but after installation, the write speed I get on the USB hdd is 1mb/s, while it used to be 10-30mb/s beforehand.

I suspect it was noatime argument, but it is present as a mount option in in ~/,config/traydevice/default.xml

I also removed 'sync' option, but it didn't change anything.

Help anyone?

Re: udisksvm and ultra-slow USB HDD write

The post #1 of the link you gave was written when udisksvm was first introduced in the AUR.
Now it is superseded with the /usr/share/udisksvm/README file installed with the package.

The configuration file for traydevice is /usr/share/udisksvm/udisksvm.xml (see the README file).
It is no more ~/,config/traydevice/default.xml

Did you install the last version 1.6-1 ?

Concerning the speed problem:

What is the file system type of the hdd disk?
Do you know the mount options used when the speed was 10-30 mb/s?

I know about /usr/share/udisksvm/udisksvm.xml . I changed it, too.

The filesystem is NTFS. I installed the latest AUR version.

The mountoptions for 30mb/s were noatime,users,exec

Re: udisksvm and ultra-slow USB HDD write

I released udisksvm 1.7-1 with ntfs filesystem type added;
I use "noatime,nodiratime,exec" as options, but that can be changed (rw should be default with ntfs-3g).

But I could not test it because I have not presently any removable disk with ntfs filesystem.
The usage of ntfs-3g with 'udisks --mount' needs confirmation that it works.

Also I will edit the post #1 of the thread presenting udisksvm; I didn't think to update it so far and it is not up to date.

Edit: the OP is now edited.

Re: udisksvm and ultra-slow USB HDD write

With udisksvm running, and after having plugged in a ntfs disk, can you please post the output in a console of :
mount
I would like to verify the mount options and the filesystem type.

And if possible, without udisksvm running, mount the same disk so as to get the 30mb/s; use the method which worked well for you before (and tell what that method is please).
Then post the output of the 'mount' command in a console.

Comparing the two outputs will surely help to solve that issue.
