Pocket (dříve Read It Later) (Wikipedie) je oblíbená služba umožňující uložit si článek z webu na později. V červnu 2015 s vydáním Firefoxu 38.0.5 se do té doby doplněk Pocket stal integrovanou součásti Firefoxu, a to i přes odpor celé řady uživatelů tohoto webového prohlížeče. Mozilla po měsících ustoupila a z integrované součásti se stal opět doplněk. Včera bylo oznámeno, že Mozilla službu Pocket kupila (Mozilla Blog, Pocket Blog).

Mozilla.cz informuje o dvou nových experimentálních funkcích v programu Firefox Test Pilot (zprávička). Snooze Tabs slouží k odkládání panelů na později. Pokud vám někdo pošle odkaz, ale vy nemáte čas si stránku hned přečíst, můžete si naplánovat otevření panelu na později. Stačí kliknout na tlačítko a vybrat, kdy chcete panel otevřít. Firefox panel schová a ve vybraný čas znovu otevře. Pulse umožňuje ohodnotit, jak dobře stránka funguje, např. jak rychle se ve Firefoxu načetla. Podle nasbíraných hodnocení pak bude Mozilla prohlížeč ladit.

    Dotaz: Samovolné odpojování USB externího disku

    Samovolné odpojování USB externího disku
    Přečteno: 1829×
    Zdravím, mám externí disk WD My Book Essential 1TB. Při přehrávání filmů, které jsou na něm uložené (používám VLC 2.0.1), se mi disk sám od sebe odpojí a hned zase připojí. Odpojování je v náhodných intervalech. Jednou je to za 10 minut, podruhé za 1 minutu. Výpis z dmesg

    Skontroluj disk pomocou príkazu smartctl -x /dev/sdb . Ak to nie je prítomne tak nainštaluj balík smartmontools ak máš debian.

    Ako ďalší postup je použiť príkaz badblocks -v /dev/sdb a výsledok daj sem.

    Druhá operácia môže trvať dlhší čas.

    Podľa výpisu s.m.a.r.t by mal byť disk v dobrom stave. badblocks je test jednotlivých sektorov disku. Potom pozri dmesg, či sa opakujú spominané chyby. Tento test by mal dostatočne zaťažiť disk aby sa overilo, či nie je problém napajaním.Dobre by bolo napísať o akú zostavu ide a aký to ma celé zdroj.

    Ešte je možnosť, že by mal ten disk nejakú šetriacu funkciu firmwaru, ktorá nefunguje správne.

    Tak v průběhu testu jsem drknul do USB kabelu (u konektoru na HDD) a disk se ihned odpojil. V dmesgu se objevilo tohle:

    Běžel mi u toho badblocks a začal vypisovat kupu "vadných" bloků. (Hádám, že to bylo kvůli tomu, že se ten disk odpojil) badblocks jsem tedy pro jistotu pustil znovu a pořád běží. Jede asi hodinu a zatím to nenašlo žádnou chybu. Dmesg taky nezobrazuje žádnou novou hlášku.

    Disk se zatím taky neodpojil (když nepočítám to drknutí do kabelu)

    Jinak jedu na notebooku Lenovo G530 4446.

    Procesor: Intel® Core 2 Duo processor T6500 (2.10 GHz)
    
    Paměť: 4GB PC2-5300 DDR2 SDRAM (max. 4GB)
    
    Disk: 320 SATA 5400 ot.
    
    Grafická karta: Intel® GMA 4500MH
    
    Síť: Intel® WiFi Link 5100AGN , Realtek Gigabit Ethernet, 56Kbps data/14.4Kbps fax
    Test nechám ještě běžet dál a uvidíme jestli se disk odpojí.

    Píšeš, že sa odpojil pri pohnuti káblom diksu. Skúšal si vymeniť kábel k tomu externemu disku ?

    Jiný USB kabel u sebe zrovna nemám. Pokusím se ho zítra od někoho půjčit. Jinak od té doby, co jsem spustil ten test, se disk ani jednou neodpojil.

    Taky může být problém přímo v konektoru - špatný kontakt a nebo urvaná nožka z plošnáku - prostě studený spoj.

    Já bych neřekl, že problém je v chybných sektorech na disku, protože z protokolu je vidět, že mezi připojením a odpojením žádné chyby nejsou. Naopak se objeví až po té, což je logické, protože blokové vrstvě zmizel hardware včetně požadavků, které byly odeslány před odpojením.

    Tipnul bych si na chybný USB řadič nebo nedostatečné napájení disku nebo chybu v USB redukci. Tyhle věci bohužel nemají žádnou diagnostiku. Jediné, co bych doporučil, je vyzkoušet stabilitu s jiným počítačem, nebo vyzkoušet disk/redukci s jinou redukcí/diskem. Především s méně energeticky náročným diskem.

    Ještě je možné, že Linux USB zařízení odpojí po překročení 100 mA, jak velí specifikace. Jestli by ale o tom něco rozumného napsal do protokolu, netuším.

    Hm, mel jsem vzdycky za to, ze USB zarizeni pouze nahlasi svuj odber pri enumeraci. To kolik skutecne zarizeni odebira USB sbernice standarnimi prostredky nezjisti. A ze by to bylo pouze 100mA se mi take nezda. Mel jsem za to, ze je to kolem 0.5A na zarizeni.

    Je to Ubuntu? (Nevidím uvedený OS, pokud někde je, tak sorry.) Dělalo mi to totéž s WD při přehrávání hudby. Otřesně otravná věc. Nijak jsem to neřešil, nevěděl jsem jak. Jen jsem přebootoval do openSUSE (mívám dva tři systémy kvůli testům) a z ubuntí partišny udělal záložní storage. Nejlepší řešení. Už na to Ubuntu nesáhnu, ani kdyby mě za to platili.

    Ubuntu to není. Používám Debian, takže je dost možné, že mají v sobě stejnou chybu.

    V openSUSE se ten disk neodpojuje?

    Nope. Jede. Zrovna z něj hraju. Nebylo to ve WD, Ubuntu mi to prcalo i s normálním notebookovým diskem, který jsem měl připojený přes USB.

    Tak jsem použil jiný USB kabel a disk se přestal samovolně odpojovat.

    Všem děkuji za rady :)
