O redimensionamento da partição falha com o Gparted ao redimensionar a partição fat32. Ubuntu 14.04

Eu pareço alguns posts sobre problemas semelhantes, mas não consegui encontrar um com uma solução para o meu problema. Estou executando o Ubuntu 14.04 no meu PC e desejo redimensionar e adicionar uma partição em um pendrive que contém uma versão ao vivo do ubuntu 14.04.

Carreguei o Gparted usando um CD ao vivo do gparted. Em seguida, redimensionei a única partição nele para armazenar os dados e deixei algum espaço livre. Na nova partição não alocada, criei uma partição com o sistema de arquivos ex4. ao aplicar as alterações, encontrei um erro ao reduzir a primeira partição.

Alguém tem alguma idéia de como resolver esse problema?

Aqui está a saída do erro:

Create Primary Partition #1 (ext4, 4.88 GiB) on /dev/sdb

O Linux fschknão corrige de forma confiável todos os erros FAT. Se você puder colocar as mãos em uma máquina Windows, faça um chkdsk /f x:where onde xestá a letra da unidade do USB nessa máquina e redimensione novamente.

Se você não tem acesso a uma máquina Windows, faça o download do FreeDOS .

Obrigado a todos! Eu usei a sugestão de Fabby e corri chkdske houve erros que o Windows corrigiu, mas não resolveu o problema que eu tinha.

Decidi que pode ser que o próprio pen drive seja a fonte do problema, então o substituí por outro pen drive e repeti as etapas (formatação para FAT32, instalação de um Ubuntu ao vivo inicializável com persistente, exclusão de arquivo casper-rw, redimensionando usando o live CD GParted e criando um novo nome de diretório casper-rw).

Desta vez funcionou!

Este parece ser um bug com a versão específica do gpartedUbuntu 14.04. Falhas repetidas ao redimensionar partições fat32 usando o Ubuntu 14.04 também são relatadas nesta pergunta do Askubuntu .

A solução (para mim) é bastante simples. Use o Ubuntu 12.04 ou versões anteriores em outra máquina ou em um liveusb. Consegui reduzir as partições fat32 em pen drives sem nenhum problema.

Se o objetivo é ter um ubuntu ao vivo na unidade flash com partição persistente, você nem precisa de um Live CD do Gparted. Você pode configurar as partições primeiro e depois instalar o ubuntu ao vivo mais tarde com o usb-creator-gtk.

Basta inicializar a partir do cd do ubuntu ou até mesmo usar o virtualbox para executar o ubuntu e tudo pode ser feito em uma sessão. A versão do Gparted disponível para Ubuntu pode criar e remover partições sem nenhum problema, mas sempre (?) Falha no redimensionamento da partição.

Acabei de criar o libparted / Gparted a partir da gitfonte no Ubuntu 14.04, parece que o redimensionamento do FAT32 funciona com isso; YMMV. Aqui estão minhas anotações (por exemplo, trabalho /tmpaqui e não instalo; também sinto muito pela bagunça):
