If so, suspect range widens, both hardware & software. I sometimes see some problems on my laptop USB with at least 6.1 & 6.2-rel, some of which could also materialise on a tower with USB (& reshuffling space, moving 30G of src/ ports/ packages/ distfiles/ & music between internal & 2 external drives is a way to get trouble. - External drive hangs. Apparently it used to hang on previous owner's XP too (but was that drive or XP or owner or ?). It has a FREECOM USB2-IDE Controller in enclosure). - Failure to flush blocks on halt (not sure if seen this with no USB). - Carbus Belkin USB2 card gets far too hot, painful to touch at times (& my brother's same type card he used in same type laptop under XP, died after he `cooked' his card in my laptop. Never gets so hot under MS-XP but I have no idea how (or desire) to load an MS-XP hard. (I wonder if perhaps MS-XP switched the card to power saving mode whereas maybe FreeBSD left it on all the time). - Potentialy USB2 ZediWorks hub, or cable, but no reason to suspect those. Of course many externals also use own power, & I can't say I've yet monitored all external power supply under load with both DVM & scope :-) I've known hubs drop to 1% of traffic because capacitors in power block dried out; also had a tower (new everything except old power & chassis) be unstable, & crash when scsi cdrom spun up, which gliched power. There's always power to consider, especially if everything at max. -- Julian Stacey. Munich Computer Consultant, BSD Unix C Linux. http://berklix.com Ihr Rauch = mein allergischer Kopfschmerz.
