O que causa isso?
No menu de inicialização, recebo os seguintes avisos:
Disk /dev/sdb - 12 GB / 11 GiB - CHS 1502 255 63
Partition Start End Size in sectors
P FAT32 0 0 1 1502 63 33 24133632 [NO NAME]
Boot sector
check_FAT: Unusual media descriptor (0xf0!=0xf8)
Warning: number of heads/cylinder mismatches 4 (FAT) != 255 (HD)
Warning: number of sectors per track mismatches 16 (FAT) != 63 (HD)
OK
Backup boot sector
check_FAT: Unusual media descriptor (0xf0!=0xf8)
Warning: number of heads/cylinder mismatches 4 (FAT) != 255 (HD)
Warning: number of sectors per track mismatches 16 (FAT) != 63 (HD)
OK
Sectors are identical.
A valid FAT Boot sector must be present in order to access
any data; even if the partition is not bootable.
Depois de escolher Reconstruir BS (Bootsector), recebo avisos:
Disk /dev/sdb - 12 GB / 11 GiB - CHS 1502 255 63
Partition Start End Size in sectors

Extrapolated boot sector and current boot sector are different.
Após o término do setor de inicialização de reparo, nada muda: ainda posso copiar a mesma quantidade de arquivos que antes
Como corrigir esse problema? (arquivos muito importantes) Talvez eu deva usar o Repair FAT Very Dangerous! Especialista apenas! opção?
