But it could be from other causes. A couple of things to keep in mind. You should not run mkdosfs with the drive mounted. From the dosfsck output, the system thinks it is a FAT32 file system. You may want to run "fdisk -l /dev/sdb" to double check the partition type. Dumb question - are you running mkdosfs on /dev/sdb1, and not /dev/sdb? Running it on /dev/sdb will produce strange results, including possible corruption of files on the device, possibly without messing up the directories...
