    flash drive ejected improperly- lost files

    Someone I know was in college and they were working in Flash CS3 and their USB flash drive got pulled out accidentally. Now, it is not being recognized by Mac or PC. The said flash drive has been used mostly with Mac but might have been used in PC. (Friend doesn't remember.) What can we do to recover the information from drive - no computer acknowledges it? Could it be that the connector is damaged?

    (re done from other answer)

    If it is not recognised at all (as if device is dead), there are a few ways:

    1. Send to a data recovery company.
    2. Buy an identical stick and swap the memory module across (careful and be quick, had quite a lot of success with this).
    3. Check contacts.

    As you said, it is not recognised at all rather than corrupt or not working, this usually means hardware failure more than anything else - so it is worth checking in case it really was yanked out to fast and the contacts broke. If the contacts are fine, it could of just been a cheap stick and has a unknown/cheap chipset, I have seen many that go faulty for all sorts of random reasons and in which case, as I said, moving the memory chip to an identical stick can sometimes fix it.

    Is it possible to boot from a USB flash drive on a Mac?

    Current setup is an iMac (early 2008) running Snow Leopard. What do I need to do to have the Mac boot from the USB stick?

    Yes, you can change the device in Startup Disk preferences, or hold the option key when booting to access the Startup Manager and select your volume as the boot device.

    More info and necessary requirements for the device can be found here (apparently the method is the same for powerpc based Macs).

    All Intel based Macintosh computers can boot from USB, and Firewire devices. PowerPC based systems are not generally able to be booted from USB, but can be booted from Firewire devices.
