Question: I can't get drive to work. I plug it in 3 different machines. It does not read. What to do?
Document: I bought this for my son's school work but after using it once the files copied but couldn't be read. I help my son reformat the drive after being told on three different computers that drive can't be read by two windows 8 and one windows 7 computer.
It worked fine for the first couple of weeks, now with 235 GB free, my computer won't write a 4 GB movie to it; says there's not enough room. My brand new Blu-ray player now says the files are corrupt, won't read any of them. It worked fine 3 days ago. Spend the money and get a brand-name flash drive, don't bother with this one.
I read the reviews on this item and was a bit put off by all the problems that other people are having. I must say that my Flash Drive arrived a day before it was due and it was in good condition.I plugged it in and it was seen by my windows 8.1  at once. I then formatted it with exFAT  and started to use it.I have as of today,  4 days after receiving it,  completely loaded it up and erased it 3 times.
I check this flash drive because I want to do an experiment but now is not possible with this pen drive, after check very well is only 64 gb, still is a good presentation but on every place indicate 256 gb, If you required 256 GB is not it, with windows 7 work fine but still I need to put time to assure the pen drive stay alive. Only one start because is a lie to said  a side and is completely different.
its been 3 weeks and im still waiting for my refund.There product was defective.Did not work properly.And neither did the 128GB one I bought from them.I sent them bought back.they owe me $50
All looked OK until I unplug it, when I plug it back in again I could see the size of data on it but most files were invisible. If anyone got this and got it to work please post your method here. Thanks in advance
I just doesn't work. Save your money. Do not buy this item. I wish I had read the reviews before I bought it.
I cannot get it to write and read more than one time. I continually have to reformat it. I gave it to a techie friend and he thinks it's one of the hardest puzzles he's had to solve, good thing he likes puzzles.
I do not even know who makes these to see if they put out a Format utitily for this device... Any one know who makes this.. If you do.. Please at least post that info..any info will be good for those that have these to get them to work.. Thank You :)
I liked my flash drive very much. Very good price for a heavy duty high capacity flash drive, and when I plug it into my computer and my Galaxy note 2 it immediately gets recognized.
Answer: These drives don't work.  Other Amazon customers have commented on this thumb drive and the comments are negative.  Read the comments.  The manufacturer told me if I changed my review from one star they would give me a refund.  I don't think there is any way to get this drive to work
