I have a 2 gb Cruzer flash drive that is no longer recognized by

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.

Yes I would agree with that synopsis ! However the OP reported an "Over
Current Event" Which suggests SC rather than cracks caused by flexing.
Those would tend to cause intermittent loss of recognition !
