USB Flash Drive Problem

Recommended Posts

liquido

For some reason my Flash drive is not recognizable.All 3 USB ports are working on my laptop because other devices are able to work..I even tryed it in my tablet USB port but still not recognizing it..Its a 32gb Scandisk, that I have had for a couple years..I did have a habit of always leaving it plugged in if that made a differance..I do have some data on it that I would like to get back ...Is there a last ditch remedy that I could try before I smash it? Never had one crap out like this.....

Did you try going to Control Panel, then Administrative Tools, Computer Management and then Disk Management to see if it's recognized there? I've had problems with USB drives before that I had to reconfigure using the tools contained therein. :)

Yes I have tryed that also with no luck recognizing it there...I do have another USB flash drive that works fine so I know its not my laptop or tablet..I really did not know that they can burnout or whatever..

"Also, you should “Eject” the drive (Do a right click on the USB drive and select “Eject”) before removing it from your computer.

Do not leave it plugged to the computer for prolonged period of time. If you do not use it, just unplug it from your computer."

Im Guilty...

Quite a rare occurrence ....I have accumulated a lot of drives in various forms over the years ...generally treated them badly and never had one go down ...I wish I could say the same for hard drives which I nurse like babies and for no reason they just disappear on me ...

tried other computers?

flash drive, like SSD, is certain to die after some amounts of writes. Non-recoverable, everything would be lost.

It's usually a good idea to backup important data in traditional HDD, which would give you lots of warnings before final death.

No ...hard drives can fail instantly as well...this much I know..a physical head crash can not only fail but trash the disk in the process....no storage is immune from immediate failure.

but having your data in two places at least is common sense.

Last ditch attempt is to freeze it. Sometimes a trace gets cracked. Put it in a ziplock bag to keep it dry, put in the freezer, or a bowl of salted ice. Remove from bag and try immediately to recover data. Good luck.

Not necessarily ...could be something like a power spike or a sudden power cut or maybe a build up of heat ...and sometimes they just fail for no apparent reason.

I have one USB stick that has to be moved around in and out or side ways before it's recognized.

Check pin plate for dirt and if bent down (away from contacts)

I've had PCs that booted from a USB drive, wasn't an issue for years of use. How much they get written to is probably a bigger deal.

I had this problem with my Kindle not being recognized on my desk-top..which is bad because I have over 8000 books stored on a separate HD (along with movies,music..pictures..etc)
I ended up flashing my MB and getting some updates for it... it worked..it is also way faster now..

All I can say is YOUR THE MAN....It worked...I placed the USB drive in the freezer like you said in a ziplock bag for about 6 hours..I then took it out and promptly put the drive into my laptop..Right away it started blinking and all the files popped up on the screen..I immediately transferred them to my laptop..The USB drive finally crapped out in about 10 mins,plenty of time...Unfrickin believeable.....Thanks Again  
Have seen this done on car radios "legally"
Buy a second hand radio from a wrecking yard.Code not known.
Put radio in freezer, radio "forgets code"

This freezer technique might work in certain parts of the world but here in Cebu if you put any metallic object in a freezer in a ziplock bag then the moment you expose it to the air it’s covered in a layer of moisture ....electronics plus moisture is a very bad combination.

Whilst I will agree with you musicman666 100%, I will convey this little story out of interest.

I went through Cyclone Tracy in Darwin Christmas 1974.

Hundreds of TVs and stereo systems got a right old soaking..(the ones that didn't blow away)

We laid them in the sun for around 48 hours @ 34 degrees and to our surprise they mostly fired up.I'm not suggesting that they weren't damaged long term, however
I new one TV that was going 7 years later

Again this is only a story and not recommended..

I've definitely seen radios recovered but sometimes the LCD screen dies as the crystals don't like that amount of cold.

Actually water is an insulator - it, by itself, is not conductive.  But the dirty air of Cebu might make it an issue.

Ok ...I’m learning ..if pure water which is what you get from cold surfaces in humid air then you should be good to go. Air quality has little to do with what comes from distillation ....it should leave the pollutants behind.

I'm learning also. Glade you mentioned that water was not a good conductor.
I was puzzled and went investigating, Wikipedia has some interesting articles.I understand the first and last paragraph. But the calculation haha

From Wikipedia....

Pure water is not a good conductor of electricity. Ordinary distilled water in equilibrium with carbon dioxide of the air has a conductivity of about 10 x 10-6 W-1*m-1 (20 dS/m). Because the electrical current is transported by the ions in solution, the conductivity increases as the concentration of ions increases.

Only if the surface it's condensing on is spotless and the air has no dust; in other words, pretty much never.
