Eu tenho um pendrive da Alcor de 4GB, ele ainda dá sinais de vida mas não consigo mais acessá-lo, quando o coloco no Linux, na porta traseira, a luz acende, o sistema reconhece, mas ele não monta, nem se for manual, no windows a unidade aparece, mas fica com a mensagem "Insira um dispositivo na unidade G:", eis o que o Linux me informa sobre ele.

Eu tenho outros dispositivos usb funcionando normalmente na máquina, meu mouse por exemplo é usb, tenho outros pendrives que funcionam normalmente, se alguém puder dar uma dica, sobre formatação, não tem como no windows pois ele não é reconhecido, só montado como unidade vazia.

valeu!
