I have a 2 gb Cruzer flash drive that is no longer recognized by
computers. I've tried it in several and they do not see it and the
LED does not flash. When it was last connected to a cpu, the screen
gave me a USB overcurrent message and now the drive no longer works.

Its no longer under warranty so...
Does the circuit board have a "fuse" on it that could be blown? I've
looked it over and don't recognize one. There's a osc crystal, a
couple of IC's and several trans/caps/res units.
You might be lucky and a cap has gone SC. More often the controller
chip is dead.


Well one of the most common (non physical abuse) problem is corruption
of the file system since there is a unique read/write algorithm used
to spread the usage of the file system over the entire flash memory.


Probably the most common fault I've seen is a result of physical abuse,
and that is minute cracks in the print or soldered joints where the USB
connector meets the pcb. Repairable in some cases tho it requires the
touch of a midwife to be successful.

I mean really! The poster cited a USB overcurrent message. Do we really
need to guess what kind of flash drive would give an overcurrent message. I
could see this kind of thing with a portable Hard Drive. Gee, why not try
plugging it into one of the rear ports and see if it will pull the power
supply down? Lol! I like the joke about "too close to bodily fluids!"
Something about Cruisers and Hot Pockets!
