Dotaz: problem s ext. hdd

[jany2]

zdravim
Znami mi dnes doniesol externy hdd, ze mu jednoducho nefunguje, nieco mi splietal, ze ho formatoval a od vtedy nechce fungovat.
Ja pouzivam linux mint 17 a po pripojeni na usb ho system nenasiel. Spustil som gparted a tam som ho nasiel pod /dev/sdd, tak som skusil format do ntfs. Ale format trval hodne dlho (viac ako 15-20 min) cize format sa asi nekonal a neslo to ani ukoncit. Ukoncil som to hrubou silou t. j. rebootom.
Skusil som teda konzolu

fdisk -l

Zastavy sa na 139/7453 a hotovo. Ked som tento postup cez terminal uz raz skusal, tak sa to zastavilo na 177/7453
Da sa tomu hdd este nejako pomoct ?

Hodnoty akcelerometra v SMART sú v normále?

[NN]

Je to USB disk? Da se vyndat a zapojit bez radice? Jak vypada SMART? Kdyz se to "zastavi" jsou v dmesg videt pokusy o zapis? Co rika badblocks?

[jany2]

Tak neni pravda to co som pisal, ze sa zastavi na urcitom cisle. Teraz je to uz 252/7453, ale uz ubehla od vtedy hodina. Skusim to prejst smartom a dam vediet

[jany2]

NN prilis vela otazok na mna :) Vybral som ho z ramceka a konektor vyzera takto takto takze asi nepojde inak, nez cez usb.
Co mozem ponuknut zo smartu ?
spustil som

smartctl -a /dev/sdd

1200 realokovanych sektorov a 160 pending - to nevyzera dobre. Skus cely disk prepisat cez dd (dd if=/dev/zero of=/dev/sdd bs=1M oflag=direct) a pozri, ako bude SMART vyzerat potom. Obavam sa ale, ze tie vadne sektory budu pribudat.

[jany2]

dd if=/dev/zero of=/dev/sdc bs=1M oflag=direct

spustil som to asi o 9:00 a este to neskoncilo ... terminal je cisty. O hodinu musim odist, cize to musim vypnut

[lertimir]

když neumíš počítat tak si to užij. pokud je to USB 2 tak jsi na cca 30MB/s, což je cca 33 000 sekund na zápis 1TB. tedy skoro 10 hodin. A dvojnásobek toho času by trvalo formátování na ntfs bez -f (jednou zapsat podruhé přečíst). USB 3 bude tak 2x rychlejší ale asi to bude záležet na procesoru. (iotop ti řekne kolk dat tam jede.)

=> Disk je chodici mrtvola.

[lertimir]

A vzhledem k počtu najetých hodin je to buď velmi špatný disk, nebo s ním bylo špatně zacházeno. Jedou mi spolehlivě disky s 10x i více nájezdem hodin.

[k3dAR]

jen 10x? vzdyt ten disk nebezel ani tejden ;) ja mam disky co maji hodin 300x vice a jsou bez vadnejch sektoru... tohle je proste disk na okamzitou reklamaci...

[lertimir]

Hm. co je Spin up Time. Myslel jsem že je to rotace ploten v hodinách. a to má 2133. ale pak není logické že power je 144 moje numera jsou např.

"Spin up Time" je cas (v ms) potrebny k roztoceni, i kdyz u Hitachi nebo Seagate mam 1 nebo 0, u WD jsou to radove tisice...

cize podla toho vyzera ze isiel 6 dni. Ten disk je externy, neni zalozeny v pc a znamy si tam stahoval nanajvys nejake filmy .... Mozno ze bezal len 6 dni, ale ak si spominam, tak hovoril, ze disk ma asi 3 roky (ale to az tak moc nepamatam, nejak som tomu nevenoval pozornost).

Kazdopadne ak by bol v zaruke, tak mu odporucim reklamaciu

[ES]

HDD je mrtvej. I kdyby se s tim nekdo chtel babrat a oznacovat vadne casti, tak se na to v zadnym pripade nadaji nahrat data ktera maji nejakou cenu.

[lertimir]

Formátování mkfs.ntfs bez parametru -f nuluje celý oddíl a čte bad sectors, takže dvakrát projede celý disk. Při USB rychlostech je to operace na několik hodin.
