A new USB what? Is it solid state or a spinning disk? – Anonymous Jan 22 '10 at 5:30
@Anonymous I wondered too, but then I saw the usb-flash-drive tag. I'm thinking either reformat or dead out of the box. – Scott McClenning Jan 22 '10 at 5:45
It was the new USB , i bought from ebay 32GB from hong kong. I tried formatiing it but same thing happens – Mirage Jan 22 '10 at 6:30
Never ever buy any flash memory from ebay, there's more fake than real on there. – Mokubai May 2 '10 at 12:30

There are times that hardware is tested at the factory as satisfactory but due to shipping, handling or storage can become damaged if not outright broken. I've had this happen with high-end xeon servers, external usb hard drives and even memory. There's way too many times this has happened at work or at home. Simply package up the device, call in a service ticket with the manufacturer and send the product back for a replacement. Or if you still have a reciept and it has been 30 days or less since purchasing the item, take it back to the place you bought it from unless it's an online purchase, and they will replace the item with something of equal value and specs.

But yeah, this stuff happens for we are not dealing with rubber and wood, these technologies tend to have quirks at times.

Which operating system do you use?

Often there is a problem with the encoding or character set.

If you're using a *nix OS put iocharset=utf8 something similar to your etc/fstab

/dev/sr1 /media/WD\040SmartWare udf ro,nosuid,nodev,relatime,uid=1001,gid=100,umask=77,iocharset=utf8 0 0

that kind of misconfiguration won't corrupt a file, just a filename. – quack quixote Jan 22 '10 at 10:15

Besides hardware faults, there can also be other causes to such a problem :

  1. A too-old chipset driver in your computer
  2. The USB enclosure does not fully conform in its specs to whatever your computer expects

If replacing the new USB disk to the same brand and model doesn't fix the problem, you might try buying some other brand (better google first for reviews). You should also search if a newer chipset driver exists (but take great care when updating it).
