    is there any need to click on the icon in the system tray and remove the hardware each time you want to unplug a memory stick?
    most people at my college just pull the stick out once they have finished, but i was always told not to do that because it can curropt data.
    is this true?

    It can be like taking a floppy out while the light is still on, usually its not a big deal though unless a file is being worked with at that moment.

    On a side note, you can disable the need to do this. In your device manager, find USB stuff and disable caching, then you can just pull it right out every time.

    Good to know.

    (use U3 technology myself... just click eject) Could you also right click on the drive in windows explorer and choose eject?

    No and no.

    1. As long as the USB drive is set to allow quick removal instead of maximum performance (and Windows 2000/XP sets them this way by default), then data is only being written when you see the light on the drive blinking. The same goes with external hard drives.

    2. The ground contacts on a USB plug are longer than the live contacts, so the ground contacts connect first when the plug is inserted, and disconnect last when the plug is removed. The same applies to FireWire, SD cards, Memory Sticks, PCMCIA/Cardbus/ExpressCards, CompactFlash, Serial ATA, and virtually every other plug-in device created after the 1980's.

    As previously stated, Windows 2000/XP are set this way by default.

    i found that most linux systems will not fully write to the drive if you do not unmount it properly first

    that's because the default mount parameters include "async". If you add "sync" to the parameters in your /etc/fstab then it's fine.

    Funny when my beagle pulled the plug on my hub with a memory stick in it it shorted the drive and gave me a cool power surge message in a balloon

    more likely a problem with the hub than the usb spec.

    I've never had an issue when plugging in my usb drive. Hell, I've never even noticed the safely remove hardware. Usually only when it is a printer or something of that nature
