Dotaz: Nástroje na obnovu HDD

[Martin]

Chci se zeptat jaké používate nástroje na low level formát hdd.
Po roce používání se mi nějak zpomalil externí hdd.

/dev/sdb:
Timing cached reads: 1334 MB in 2.00 seconds = 666.99 MB/sec
Timing buffered disk reads: 10 MB in 3.15 seconds = 3.18 MB/sec

To ale samozřejmě není pravda.Zápis třeba 5mb souboru mu trvá i 20min.
Je formátovaný na ext4. Štávy bude mít dost jede přes Y kabl a USB2.0 je určitě.

Je na odpis ??? Zkoušeno vícero kabelů, i pod XP a win7 . Všude stejné chování :(.
Zkoušel jsem dát read test v 'palimpsest' ale neuspěšně. Píše že disk je pomalý
na provedení testu.

Co SMART? Nejake info?

[Martin]

Bohužel nepodporuje SMART.

[ubuntak]

to ze nepodporuje smart si zjistil jak? co vraci smartctl -a

[Martin]

/dev/sdb: Unknown USB bridge [0x125f:0xa91a (0x140)]
Smartctl: please specify device type with the -d option.

smartctl -a -d scsi /dev/sdb

Device: A-DATA   HDD CH91         Version: 
scsiModePageOffset: response length too short, resp_len=4 offset=4 bd_len=0
>> Terminate command early due to bad response to IEC mode page

[AraxoN]

Ešte môžeš skúsiť:

-d usbcypress
-d usbjmicron
-d usbsunplus

S trochou hľadania sa dá nájsť aj tabuľka HW kompatibilného so smartctl a tam je uvedené s akým parametrom to ide, ak vôbec.

Neco cemu se rikalo low level format uz nejmene 25 let neexistuje, od te doby co jsou hlavy rizene spetnou vazbou z prednahrane vodici stopy a ne velikosti kroku krokoveho motoru ktery hlavy navigoval.

Projej SMART Skusit badblocks...

Ale ono uplne staci "dd" a skusit prepsat nulama pokud nepujde nebo bude extreme pomaly tak vyhodit.

[Martin]

Asi opravdu zahodit.
Badblocks jeli cele odpoledne i noc. Ráno stále jeste nedojel prvni pattern.

[R]

Vyber ten disk znutra a pripoj priamo. Potom sa mozes pozriet do SMARTu.
