I guess I've been lucky, because I haven't had much of a problem with various USB storage devices so far. I haven't been on FreeBSD 6.x for long, though; I went straight to 7-current a few months before 7.0 was released, then followed the 7-stable branch. The only thing that doesn't work is detaching a device (whether USB or other) while it is still mounted. This is supposed to be fixed in 8-current. (My personal impression is that 8-current is quite reliable at the moment, so if you have a spare machine it might be worth giving it a try. Be sure to subscribe to the -current mailing list so you don't miss any important "heads up" messages.) Another thing worth mentioning is that a new USB stack is under development by Hans Petter Selasky. I'm not sure when it will be committed to 8-current, but I think it's pretty much ready. It will certainly fix some of the problems people are seeing with the old USB stack. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.

Re: USB Drive Reliability
it is the usb chip that does not work ok... or works only with windows timings Please use an usb storage brand: Kingston... for externals usb drivers, I recomend seagate... format them with a UFS2 file system using sysinstall, place a Freebsd partition on it and format it this way you can use all the freebsd features, and your system will never hang... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

That sounds familiar, but I guess most USB storage devices are very similar, so maybe start looking at the USB controller. I know in my case, installing a PCI USB card with _NEC_ chipset solved all my problems. Thought it worth mentioning ...

Please give us more details. If you unplug it while it is mounted, it will certainly result in a kernel panic. As far as FreeBSD is concerned, this is no different than opening the box and disconnecting your hard disk while it is running. Other than that, I have an external USB hard disk attached to my home server permanently. It is on all the time, it gets mounted / unmounted by scripts once or twice a day. It's been running for about two years, and never had any problem with it. I started using it with FreeBSD 6.x and is now on 7. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
