Hi Curt,
Caching and I/O scheduling give performance benefits which is why they're used with most media. As I understand it you're wondering if it is possible to disable write caching in Windows? The answer to that is yes. Here's an old support article that describes how: http://support.microsoft.com/kb/259716 If you do a google search you'll find it works similarly for XP. From Kernel 2.6 onwards udev (http://wiki.debian.org/udev) is the dynamic device manager. But despite searching for a while I've not figured out how to control the rules for mounting the devices. However, fstab entry "sync" or "async" controls what happens: http://www.tuxfiles.org/linuxhelp/fstab.html Sincerely, Kailash > From: Howland@priss.com > To: debian-user@lists.debian.org > Subject: Unmounting/Ejecting removable media > Date: Fri, 10 May 2013 22:47:01 -0400 > > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA256 > > Dear Debian Users, > > I was contemplating today the fact that I know several people who have > scrambled various removable disks and thumb drives by failing > to "unmount" or "eject" before removing them. > > Mostly this has happened in Windows, not because there isn't > an "eject" feature, but through ignorance or accident. > > This happens, I am told, because of unwritten buffers which are > emptied only when the device is unmounted or ejected. > > Why? > > Removable media are already a class unto themselves, so why aren't > they marked something like "sync immediately"?
