Non-Working Cruzer Flash Drive

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.

If you don't have critical files on that flash drive, forget it. My last
purchase of Cruzers (4 GB each) was only about $33 for three of them.

If you do have critical files that you need to get back, may God be with
you.
 
You might have done something that corrupted the RAM. (I did this to one by
accident.) If this is the case, it's unlikely you'll be able to get it
working again.

Was it setup with an encrypted filesystem? If so, try to reinstall
the Secure utilities (which won't work if you can't access the drive):

It's melted into a solid blob of silicon. Give up.

Sounds like one of the chips/caps has shorted out. Throw it in the bin &
get a new one.

it's possible the controller IC has failed.
I have an Attache flash drive with a transparent case,you can see two large
ICs;one is the memory IC and one the controller.

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.

Unfortunately this isn't something that can be recovered from by the
average person.

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.

Actually, there's another possibility. It might be a counterfeit

In the past, I've run into various flash drives and camera cards that
were counterfeit. They didn't last. A few were dead on arrival.
Looks like the Sandisk Cruzer drive is a candidate:

Topic drift: I've been testing the speed of flash drives with
FDBench. It works but isn't really very useful. Most of the hard
disk benchmark utilities don't seem to recognize a flash drive as a
hard disk. Is there a Windoze program for benchmarking flash drives?

Did anyone get the memo?

This is like trying to do a recovery on a hard drive after it's been on the
drill press.

Well, I remember having lots of options in SisSoft's 'Sandra'; just checked on
the Web and indeed it has flash drive benchmarks. It's big, but even as
paranoid as I am, I found that it doesn't muck up the system and is pretty
open and transparent during and after installation.

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 !

You wouldn't want to anyway, because it doesn't happen until most of the

Try this freeware utility: http://www.steelbytes.com/?mid=20 This works
great with just about any disk drive. Note that the write tests are
destructive, so back up your data.

I've repaired a couple with broken USB connectors. One that got driven

Depending on your flavor of Windows yes. In Vista you can use the
extended info for the file transfer dialog. My 8 gig Cruiser does it
at about 6 MB/s. Hard drives in my system can sustain 60Mb/s between
them.

hard drives are recognized even if they are brand new and no file system.
other USB devices get recognized without "recognizable file systems".
