Flash disk Can anybody recommend or suggest a method of low-level formatting USB flash disks on any platform? I have a number of Maxell IGB and 2GB retractable USB flash disks which I bought recently for use as backup media, but many of them have turned out to have bad sectors which only show up when trying to read back files stored on them which span one or more of these bad sectors. Does anybody have a solution, please? I have heard that some cheap USB flash disks are unreliable in this respect, and I cannot deny that these were rather cheap, but I had assumed that they were reduced in price only because drives of much larger capacity are now readily available and I did not expect Maxel to base their devices on unreliable flash memory.
