Everything is in the title, after 2 months and 3 or 4 uses while for everything, the key does not rise at all on macs and is unreadable on a PC. Unable to format, nothing to do either with the software provided on the manufacturer's website. In short, it will just be used to put important files, now irrecoverable. I'll return the key to the manufacturer as amazon proposes to take over the port do (always on top, thank you) that is not even the manufacturer (even you pay sending the netherlands!) But that's for in exchange have the same type of key and not finding my data from the information Corsair. Several testimonials on their website show that I'm not the only one having problems with this brand ...
Edit: read the full story: the USB key is stranded again a few months after the "repair". So I very strongly recommend this purchase !!!
