Comment 20 for bug 106931

I found a way to make it works correctly on gnome.
First : mount volume without read-only using "Storage device manager".
Second (only for NTFS volume) : Install ntfs-3g driver. Use "ntfs-config" to mount drive with ntfs-3g.
Third : Use hdparm command to make the drive works better (activate DMA, 32bits and umaskirq)
------------------------------------------
HDParm syntax :
test your drive perf -> sudo hdparm -tT /dev/hd(x)
modify above value -> sudo hdparm -d1 -c1 -u1 /dev/hd(x)
------------------------------------------
And for finish : Fix the hdparm settings using the /etc/hdparm.conf file because the above command
are for the current session only.

It works well for me while waiting for bug fixing ;)
