USB jump drive LED dont blink when plugged in

August 28, 2010 at 14:46:17
Specs: Windows Vista

Was using a Sony 4GB MicroVault flash drive thought I was finished using the files, removed the drive from my computer then realized that I needed to print one more thing. Put the flash drive back in and now the LED light will only stay on steady will not blink. The message appears that the USB is not recognized. Is there hope to get my data off the drive?

1. Does the computer fail to recognize the USB drive after you restarted the
2. Did you try different USB ports on the computer?

Yes - the computer failed to recognized the usb - Tried it out in all the ports on laptop. Also tried it out on several different computers with XP and vista operating sytems. Shutdown and restarted the computer several times. NOTHING!!

In that case I think this drive is faulty. How that happens? Who knows but the most common cause is the failure to use the Safety Remove Hardware routine before pulling out the device,

Below is a list of LED behaviors which are all NORMAL (courtesy of ScanDisk).
1. LED is a solid light and blinks only when transferring files to the device.
2. LED blinks rapidly during initialization then turns off. LED then only blinks when data is being transferred.
3. LED breaths (slowly fades in and out) when device is not being used and blinks rapidly when data is being transferred.

A drive with no LED activity, or red LED or solid or constantly blinking LED can be cosidered faulty or corrupted (remember this is just MY BEST OPINION and I am not the authority on this thing :-)

I've been thinking that what you posted was the case but still clining to hope - LOTS of important data on there - committed the cardinal sin - Did Not Back Up the USB data to my computer on a regular basis.

Thanks for your insight on this.

There's probably nothing wrong with the flash drive itself.
