Setting /sys/block/sdb/device/max_sectors permanently to 128 for specific device
Dear udev gurus,
After breaking the second Clip+ player I got a Samsung YP-R2 portable
player which plays OGG files and is accessible as a disk with MSC mode.
Only problem is the device keeps being reset at any copy/move/delete
operation.
Googling provided a solution which seems to work [1][2] which consists
in setting max_sectors to 128 istead of the default 240.
I can do that as root manually but I'd like to have it done
automatically when the device is mounted.
My understanding is that a udev rule has to be created, I would
appreciate some help on:
- Where to put the rule
- What to put as the vendor (link [2] mentions vendor) and how to
discover it so that the rule only applies to that very device.
System is: Wheezy with XFCE 4.8
Thanks in advance for anyone's help.
Lorenzo
