You should throw it away. Unsolicited or free usb sticks are not safe.


Er. I know salespeople aren't usually technically literate, but it is highly unlikely they're knowingly distributing malware, spyware, or electrical attack devices to potential customers. Salespeople who actively hurt customers usually make very few sales and auto-Darwinate.

Also, the USB drive obviously wasn't an electrical attack device, and it wouldn't contain malware at all if Daniel had run mkfs on it. It might've been a flash drive with a lot of bad cells. It might've been a larger piece of flash memory where the controller chip was set to say "only make 8031 512-byte sectors visible". Regardless, if the thing reports "my capacity is 8031 512-byte sectors" via the USB Mass Storage protocol, then that's all the kernel will let you use. You may want to have a look at what dmesg says about this device, or check out the debugging options you can feed the usb_storage module--that may give you some additional info.
