The last time I _accidentally_ removed a thumb drive (it was on Windows at the time) the drive got hosed, losing everything on it. Better safe than sorry I say (I try not to remove USB sticks until I know its safe to, period). YM(obviously)MV -- dee

Right - I'm using an XP SP3 machine here at work. Opening up 'My Computer' and right-clicking on a drive (any drive) gives a menu, the last item of which is 'Properties'. Clicking this gives you a window with several tabs, one of which is 'Hardware'. Clicking this gives you a list of all the drives connected to the machine, plus an entry for USB devices. Selecting the USB Device entry I then get another properties window with a few tabs, one of which is 'Policies'. Choosing this gives you a two-item radio-button selector screen. It looks like this: ----------------------------------------------------------------------- (*) Optimize for quick removal This setting disables write caching on the disk and in Windows, so you can disconnect this device without using the Safe Removal icon. ( ) Optimize for performance This setting enables write caching in Windows to improve disk performance. To disconnect this device from the computer, click the Safely Remove Hardware icon in the taskbar notification area. ----------------------------------------------------------------------- I've never altered this setting, so the default for USB drives appears to be 'write caching is disabled'.

My wife's late dad, an actual HSE inspector, did not live a life of well-heeled luxury, I can assure you. He had two grown-up daughters when I first met him, and a few decades of doing well in his career behind him. He lived in an unremarkable semi in an unremarkable commuter belt village and drove an unremarkable Rover by way of his company car. He did have a lovely flow-through of gory photos - of the investigations he made of people who had failed to understand that H&S structures do apply to them despite the fact that they are fully informed intelligent well educated highly experienced experts in the area of activity that's just blown their face off (or similar - yes, I did see a set of `face blown off' industrial accident photos). You see, one point you are neglecting is that *even the most careful well informed experienced expert sometimes makes mistakes*. - which is what the `face ripped off by an explosion' accident was all about. Another point is that the most careful well informed experienced expert can get in the firing line of someone who's *NOT* as careful (etc). - as with me in Ireland when I had to duck because someone else's sloppiness caused a lathe chuck key to hurtle towards my head. And another point is that if you have H&S law, a worker can refuse to obey manangement demands to do something dangerous - which before H&S laws were introduced just got you sacked. Find out about the London Match Girls' strike: they went on strike because management wouldn't pay them unless they poisoned themselves, and they didn't think that was fair. They wanted to get paid without having to poison themselves under management direction. Do you begin to understand yet? > <snip> > > > >The problem is not H&S law, but hese idiots in middle management and > >local councils and semi-trained chimps employed as legal advisors > >getting the application of such laws very *VERY* badly wrong. > > You are probably right but I wasn't referencing HSE specifically but > the concept in general and for me. But you did specify the HSE specifically - see your words above, which are still quoted in this email. See? Specific mention of the HSE in your post, which you now deny! > >We *NEED* health and safety rules. > > You might, stupid people might, untrained people might, I don't. Wrong - and I've explained why but of course you ignore the facts. [snip] You're one of the reasons the HSE is vital for the safety of the nation - you're part of the health and safety problem, ever bit as much as the idiots who apply lunatic restrictions based on a crass misunderstanding of H&S law and the other idiots who cause the industrial accidents due to their idiocy. Clearly, your mind is closed to reason and there's no point continuing to try to educate you out of your mistaken ideas. But I might as well try: the *primary* means by which UK Health and Safety regulations required be used to ensure workplace safety is this: Requiring everyone to use their noggin as best they can to act safely. It's all about telling people that they are liable for accidents they cause, if they've been bloody stupid, and it's up to them to make sure that they're not being bloody stupid. That's the basis of UK H&S principles: personal responsibility. You've seen the posters - now read one!

Hmm - according to some here, that can't happen. What was going on? > Better safe than sorry I say (I try not to remove USB sticks until I > know its safe to, period). Full stop, surely ;-) But: how do you ensure `safe' unless you unmount?

Okay, so that shows that MS Windoze lets you control whether or not the host does write caching. Fair enough.
