Forcing mount options for automount in KDE 4
 

Hi all, recently I upgrade my Slackware64 to current and I notice that write speed to USB drive is very slow, especially if I copy a large file to the USB flash disk. The copy operation works fine for the first hundreds of MB and after that the transfer rate constantly drops to the point it's very slow. This makes copying 6.8 GB ISO image took more than 2 hours.

My primary suspect is the automount does not pass the proper mounting parameters for the media, as in my Windows the USB disk behaves normally and I can copy the same file just under 30 minutes.

It seems that automount process does not pass the noatime,async to mount. If I mount the drive manually from console (using mount or pmount) using the proper parameters the copy performance is acceptable again.

My question is how to force my USB flash drive to be mounted using noatime,async options. I have tried the method described here but that does not solve my problem as HAL seems to ignore the options I put in the fdi file.

Thanks.
