Good morning. > Caching and I/O scheduling give performance benefits which is why > they're used with most media. As I said, I don't mean media where transaction times are critical or anything like that. I mean USB devices, thumb drives and external drives, which are already slow as molasses. > As I understand it you're wondering > if it is possible to disable write caching in Windows? The answer > to that is yes. Thank you for the pointer, I'll pass it on to a friend who uses Windows. My question was much more general than just Windows. The problem of pulling a removable drive without unmounting it first is a general problem. Caching that isn't immediately written out to the drive appears to me to be "asking for trouble". > 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. Thank you for taking your time to investigate. It is interesting, and I will look at udeb myself as well. > However, fstab entry "sync" or "async" controls what happens: > http://www.tuxfiles.org/linuxhelp/fstab.html Indeed. Removable drives not being in /etc/fstab is one of the particulars that may make it possible to have caching "on" for static drives, and "off" for removable. Hmmmm... > Sincerely, > Kailash Peace, Curt- - -- The Magistrate, enrobed in taxes, condemns the thief in stolen rags. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iFcDBQFRjkGFtk9X6NaR4akRCNpbAQDMu6bbk6aMzI0qsyCpxhCmeCmY0rkpojjh zgc+7oqx/QEAvxVDizZehEnsHHnfucKwWrm6LL89jsg9Vk9D1GRQgeo= =bShg -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
