[Resolvido] Sistema de arquivos para hd externo

[ncc1701]

Ok,

Não está na configuração de fábrica, já formatei mais de uma vez. O sistema original era, parece-me, ex-Fat.

Ele está rodando ext4 journaling na partição que separei para o Ubuntu. No Gparted quando configurei apareceu assim: ext4 103,62GB; linux swap 2,44BG; unnlocated 13,18GB. Usei no Gparted o MiB.

lembrando que particionei o pen drive no Gparted usando o padrão de 1MB livre no início:

Fui tentar rodar agora o Flashbench, e ele não estava aceitando o comando anterior. Rodei o "sudo fdisk l", então, e pra minha surpresa, agora o Ubuntu aparece no sdb1. Aquela hora deu sdd1!. Seja como for, o resultado agora aparece bem diferente, sem resultado negativo na coluna do diff. Observe, Sérgio:

Acho que erased block desse pen drive é de 8 MiB, a page é de 32 kiB.

Agora se você quiser seguir em frente, teria que deixar 8 MiB antes da partição, sem contar outras configurações.

[ncc1701]

Ok, Sérgio, vou tentar. Você viu as páginas que coloquei aqui sobre modos de preservar o pen drive de desgastes excessivos? Vou à luta, daqui a dias digo como estão as coisas.

Abraços.

[ncc1701]

Sérgio,

Instalei no pen drive, deixando 8MiB no início da partição. Segui os tutoriais daquelas duas páginas gringas que postei, após instalação de programas, para tentar minimizar desgaste do pen drive. Rodei o Flashbench:

a primeira, somente página do Yutube aberta - 5nrhsip;
a segunda, momento de print screen - b5iw7p;
a terceira, com duas páginas Youtube e processador de texto aberto com um arquivo - 0wlva1p.

Não tenho notado nada desagradável, a não ser em raros momentos, a tela escurece quando o Firefox está acessando alguma página (freeze?).

Bem, a par das configurações do meu pc, acho que está de bom tamanho, não?

Estou me apaixonando cada vez mais pelo Ubuntu, cada vez uso menos o Janelas do tio Bill.

[Renan Rischiotto]

Não tenho notado nada desagradável, a não ser em raros momentos, a tela escurece quando o Firefox está acessando alguma página (freeze?).

É problema do Firefox + PC. Quando o Firefox escurece quer dizer que o programa deixa de responder por um determinado momento...aqui também acontecia isso (acontecia porque agora eu uso o Chromium, que é mais rápido e não dá essas escurecidas), pois o Firefox é lento, e piora se o computador for lento também (igual o meu).

[ncc1701]

Grato pela dica, Renan.

Abraços.

[Sergio Benjamim]

A questão do Firefox ficar lento as vezes se dá por conta do cache dele, ele fica a todo momento salvando as páginas no cache (para acessar mais rápido na segunda vez que entrar no site, e também tem o lance dele saber as abas que estavam abertas, quando vc fecha ele de repente). Tem como deixar o Firefox mais rápido, desativando o cache ou jogando o cache em /tmp com sistema de arquivo em Tmpfs, tem dica na internet.

Obs: não estou conseguindo ver as imagens, vc pegou o link certo do imageshack?

[ncc1701]

Bom dia.

Como posso fazer para dar o assunto como resolvido?

Grato.
