if it were so, then OP should get a new sandisk flash drive in store, not online at amazon nor ebay
then junk that broken sandisk drive
many of the Sandisk UFDs that I purchase at local electronic stores haven't failed; some of the old sandisk flash drives that I have bought many years ago are still working. I never buy such flash drives online
It is true that stores will only sell genuine articles and hence have a better chance of long term life but in the end, it is still random.
I just go for best deal online accepting risk but never use the devices as permanent storage. I only use them mostly as installation drives, rescue drives and temporary storage to transfer files from one pc to another.
If one fails now and then, I bin it and buy a new one. I am still miles ahead in terms of cost as stores are often double or more of online price and my failure rate is less than 10%.
I have several old ones 2-4GB.
Not much use but still big enough for a Macrium Reflect Rescue drive.
thanks guys, after reading this thread with the same problem on a 16gb sandisk drive i decided to stop wasting time, copied the data and went to bed.... its an old stick and my time is precious
