The Problem !!
The other day my brother came to me with 32gb San-disk USB flash drive and and ask me to help him to fix it he says it just stop working First thing came to my mind is To format it , i tried with Dos-command and no luck tried with Linux the same results no changes and i noticed that the disk is READ-ONLY (LOCKED) and there’s no physical lock on San-disk cruzer .
So.. How to fix a READ-ONLY Usb thumb-drive ?
With RMPrepUSB it is very helpful tool, I use it all the time to diagnose and fix usb-drives .
The results came with ‘ bad sectors in the disk ‘ !! that’s strange ?
Can a USB thumb-drive wear out?
The answer is : Yes.
Inexpensive flash memory, the type used in USB thumbdrives, memory sticks and other devices, is very cool. But there is a dark side, It may only take a single bit of information to be wrong to “wear out”, for the entire contents of a flash memory chip to be lost.
I strongly recommend that you make a copy and backup your data in any of your drives, sooner rather than later.
So .. I gave my brother another USB drive that i do not use much and after few days the same problem came out !? , I asked him and i found that he plugged it into his SAMSUNG LED TV to watch movies , same as the old drive and he left it plugged in after he’s finished with.
Which reminded me of an old article I’ve read few years ago on Ask-Leo.com.
Is it safe to leave a flash drive plugged in all the time?
And i quote:
“It’s always important practice to have at least two copies on different media of anything important.”
Isn’t enough ?
“Flash drives do wear out, absolutely.”
What’s The big picture I am lost ?
Two flash drives broken cause of Samsung TV, It seems like Samsung TV problem ?
Yes , it maybe , BUT
According to Leo Notenboom it’s not save to leave USB drive plugged in and it even shorten the life of the USB drive.
