Hi,

I hope you're having a good day! You ought to fix the bad sectors on your flash drive before trashing it. Starting with "chkdsk" may help.

Did you attempt to use USB Flash drive on a USB 2.0 port? USB 1.1 usually works on that port.

In FAT partitions, clusters may be marked "bad". I'm sure there are simple tools to locate these sectors & find these markings. It is also possible that there are other file systems like NTFS too.

There are two types of damage for flash drives. One is Partition table damage and another is damage to the firmware. The partition table is located in the first sector (cylinder 0, head 0 and sector 1) of each hard disk. It memorizes information about sizes and locations of partitions on hard disk.

If all a sudden your computer does not boot, and you see messages like “operating system not found”, “missing operating system” or “invalid partition table”, you know there is something really wrong with the Master Boot Record (MBR), fix it with a free, open-source utility called TestDisk. TestDisk is an influential data mending utility, primarily used to pick up lost partition tables. It can run on different operating systems, such as Windows, Linux, Apple, etc., and recuperate partitions from their file systems as well.

While you've ruled out various probable causes, sectors going bad likely means that the maximum number of writes has been exceeded on several areas of the medium (flash memory is worn out).

I can imagine a few unusual causes of the malfunction on your device:
– Corrupted file system, not caused by media, 
– A malfunctioning flash device, that has to bad blocks to be handled by the flash controller
– A pram or lacking flash controller, possibly on a product of dubious quality

I recommend you find USB flash drive on another PC USB 2.0, the problems you have described are normally when you use a USB 2.0 device on a non-supported USB 1.1 port.
Of course you can get a new one, and just assume it is a bad drive, but you can also try other things. USB flash drives today have a very low price.
Plenty of newer USB devices don’t show up on USB 1.1, or include false, broken 1.1 supports.
