Your 256GB drive will not experience a formatting problem because of its size. Formatting a 256GB USB drive, especially if it is a USB 3.0 or later spec, should not take hours, but minutes if not seconds. Assuming there was no power cut or interruption to the formatting operation the error has the smell of a hardware problem, hence dmesg should reveal if something went wrong with the device. You can try reformatting the USB drive, while keeping an eye on the output of 'dmesg -W'. If both of these sticks are behaving the same way, it could be the port on your PC which has a problem. You can try using a different USB port to eliminate this causing the formatting failure. Other than a hardware problem with the device itself, there is the chance of counterfeit USB drives, churned out at volume and having a smaller size and speed than advertised, or such poor quality flash chips they end up corrupting data. Usually they survive a reformat, at least with FAT, but can fail at any point thereafter. --nextPart2723821.X9hSmTKtgW Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
