Is it worth trying sudo hdparm -W /dev/sdf
I had the same thought, and it gives the same result (that write caching is off).
if hdparm -i doesn't work though, these might not work. I've googled for ages and I can't find any other way of telling if write caching is on or off
- sorry!
Thanks for trying! I also did a fair bit of Googling yesterday and came away far from sure I understand the difference between software and hardware!
A thought. I don't know if it will work, but there's a Gnome utility called "Disk" in my version of ubuntu 's menu (don't know the package name) that may give you info on the disk if you select it in the list of disks down the left hand side.
Alternatively, if you have a system info program installed, or install one, that may tell you if write caching is on.
It's a server install so no Gnone tools available. However I'm pretty sure they're going to just be GUI wrappers for hdparm.
I'm pretty sure that the defaults are for software write caching to be off, so I don't think this is something I need to worry about.
