Electronics Forum / Repair / July 2009Non-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. > I have a 2 gb Cruzer flash drive that is no longer recognized by > computers.

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

That if other USB devices and hard drives get recognized as hardware with no file systems this should hold true for everything you plug into a USB port?

USBview, which I have on my site, is a much earlier utility. http://www.users.on.net/~fzabkar/USB_IDs/ I have seen two versions of it, one on the Win98 CD, another one on the Web.

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. Ron >>>> I have a 2 gb Cruzer flash drive that is no longer recognized by >>>> computers.

It does look very similar with the sot23 device near the end. There are no markings at all on the chip. There is a dead short between all three pins. Same with it removed from circuit. However all three pads show a short to both power pins on the USB socket. SignatureBest Regards: Baron. >>>> I have a 2 gb Cruzer flash drive that is no longer recognized by >>>> computers.

However, when I downloaded it from the USA, German, and AUS sites, AVG 8.5 complained that it was infected with WIN32/HEUR virus. SuperAntiSpyware, MalwareBytes, and Spybot S&D didn't find anything wrong, so I think it's a false positive. However, I don't wanna try running it on this machine as the backups are about 2 months old. I'll try it later on some other machine.

I uploaded the file to http://www.virustotal.com which uses a large number of different virus scanner programs. Only three reported it as "suspicious". The funny part is that AVG didn't see it as a virus! Maybe see if there are any updates for your scanner?
