kontrola "povrchu" buniek u USB flash disku

[jcdenton12]

zdravim vsetkych

mam tu 16GB USB Kingston kluc (stary asi 13 mesiacov)
mal som na nom jednu velku EXT2 particiu, na ktoru sa moc nezapisovalo
vcera som chcel z nej vykopirovat vacsie mnozstvo dat (~500MB) a do logu to hadzalo jednu I/O chybu za druhou tych najroznejsich zneni

ani fsck nebol schopny dat ten system do relativne chodiveho stavu a kedze tie data neboli zas az take dolezite, tak som to cele formatol

pre istotu som vyskusal low level format alebo random fill alebo ako to chcete nazvat
proste cez dd som z /dev/urandom zapisoval na cely flash disk
niekde okolo hranice 14 500 000 kB to hodilo I/O error a zapis na flashku zakapal

je teda nejako mozne zistit, ci su niektore z buniek pamate uz mrtve?
nieco ako scan povrchu na klasickom HDD

mna napadlo pomocou dd urobit viackrat bitovu kopiu a nasledne porovnat hash danych suborov
ak bude rozdielny, tak pre mna to je jasne, no reklamacny technik ak nebude prave mudry, asi bude chciet dajake obrazky/grafy alebo nieco ,comu bude rozumiet


co treba za dokazy, ak by som chcel dany kluc reklamovat?

vdaka za odpovede

skus to prejst testom v hdtune, ak je pre linux, inac len pod windows.
kazdopadne, ak ti kape zapis/citanie z flashky na viacerych pc, je flashka vadna.

[jcdenton12]

tak som si teda povedal, ze si odzalohujem to co tam teraz mam a skusim to testnut na windows stroji.
mam tam
59MB particiu FAT16
13.78GiB particiu EXT4 (obsadene cca 2.0GiB)
zvysok ako Linux-Swap

FAT16 particiu precitalo uplne vpohode
EXT4 uz celu nie

martin@Martin-NTB:/media/LINUX_DATA/8GB_backup$ sudo dd bs=4M if=/dev/sdc1 of=./sdc1_partition.img1
14+0 records in
14+0 records out
58720256 bytes (59 MB) copied, 3.52267 s, 16.7 MB/s
martin@Martin-NTB:/media/LINUX_DATA/8GB_backup$ sudo dd bs=4M if=/dev/sdc2 of=./sdc2_partition.img1
dd: reading `/dev/sdc2': Input/output error
3198+1 records in
3198+1 records out
13413974016 bytes (13 GB) copied, 779.476 s, 17.2 MB/s

kedze verim, ze EXT4 uklada subory do suvislych volnych blokov a povodna instalacia (1.6GiB) tam bola nakopirovana cez dd, tak bola niekde uplne na zaciatku disku a na urovni 13GB sa snad nic nenachadza, tak som to cez GParted resizol na 8GiB velkost (za chvilku spravene, nehlasilo to ziadne chyby)

toto mi uz dd precitalo cele bez hlasenia nejakych chyb
precital som obe particie pre istotu este 2x a nasledujuci SHA-512 hash sa zhodoval, takze verim ze su OK a v dobrom stave a budem z nich schopny obnovit system do chodiveho stavu

skusim teda este parkrat precitat cely disk na inom stroji na rozdielnych radicoch a nasledne hdtune
pevne verim, ze ked DD hlasi IO error, tak to bude dostatocny dovod na reklamaciu


za akekolvek dalsie rady vam vopred dakujem


//edit:

OK, takze minimalne pod linuxom je ten disk jasny
za urcitou hranicou sa z neho neda citat a ani nanho zapisovat

skusal som to na 2 roznych strojoch a 3 roznych USB radicoch

napada niekoho nejake riesenie?

[shiro]

ak to neni problem filesystemnu, tak ten kluc proste chcipa, tu neni co riesit.

[jcdenton12]

som sa blbo vyjadril ked som napisal

hmm, tak citat s DD z toho kluca zatial viem

myslel som ze som ho vedel cely precitat pred 3 mesiacmi (ale vtedy nebolo v logoch nic chybne)
teraz som ho citat cez DD neskusal, kedze stale bezi, no akurat v read-only mode
ale poskytuje mi VPN pristup, takze zatial ho neodpajam

inac FS tam je EXT4, aky konkretny problem filesystemu si myslel?


uvidim ci predajca daco odpise a pojdem skusit RMA
akurat ze ked ho formatnem, tak on zas bude fungovat chvilu (mozno par dni, mozno aj par mesiacov) a na RMA ma poslu do ...

[Snake]

Je vôbec EXT4 určené na prevádzku na Flash médiách bez radiča čo robí WL/IOLBA? Lebo viem že NTFS malo s týmto problémy, dokonca aj nový ReFS, tam sa na zavádzanie používa FAT32/exFAT

[jcdenton12]

je mi jasne ze zurnalovaci FS mu k zdraviu neprida, ale aby skapal pol 6 mesiacoch pouzivania EXT4 (predtym NTFS na obcasne prenosy vacsich suborov)?

chapem aj to, ze cim mensi vyrobny proces, tam menej cyklov ta pamat prezije, no toto mi pripada strasne malo
mam tu asi 7-8 rocny Patriot Xporter 8GB, ktory je niekolkokrat vacsi a zial aj rychlejsi a bezi stale bez problemov, pricom ma uz znacne ohnuty konektor a bol som zmiereny s jeho smrtou, ked on kamaratka zakopla, no ten nezmar fici dalej

[jcdenton12]

takze dnes som ho vytiahol zo stroja a na moje rekvaenie som ho recital bez chyb alebo znizenia rychlosti ulne cely.
zais vsak uz vrazne somalil o takmer olovicu

kym redtym som zaisoval rychlostou 5.5MB/s a viac, teraz

homer@homer-System-Product-Name:~/Desktop$ sudo dd of=/dev/sdb if=./16GB.img
[sudo] password for homer:

31113216+0 records out
15929966592 bytes (16 GB) copied, 5617.7 s, 2.8 MB/s

je teda zjavne ze nieco mu je, avsak na RMA neviem ako zhovievavy k tomu budu

[shiro]

vyzera ze okrem disku ti odchadza aj klaveska

[jcdenton12]

takze USB kluc som dal na RMA do datacompu v piatok naobed
o ani nie 2 tyzdne uz bola reklamacia vybavena
vratili mi novy Kingston DataTraveller SE9 16GB

takze snad bude sluzit dlhsie ako tento

maximalna spokojnost s reklamaciou

klavesnicu idem odniest Gabovi zajtra na RMA

[jcdenton12]

takze ten novy kingston co mi dali z RMA asi tiez zdochol
mal som na raspberry uptime 27 dni
23. den ext4 error count: 50
24. den ext4 error count: 261
25. den ext4 error count: 704
26. den ext4 error count: 2555
27. den ext4 error count: 7938
28. den uz nebol sietovo dostupny a po pripojeni konzoly a reboote uz nenabootoval kvoli chyban na disku

teraz robim dd kopiu a vyhadzuje to IO error na urovni 320MB, 760MB, 1.6GB, 2.2GB, 3.0GB atd


zjavne plati ze cim mensi vyrobny proces pamatovych chipov tym skor to skape
nejake rady?

takze tu je vystup z dd

zjavne je pamat v prvych 6GB uz nacata a uvidim ako dlho a ci vobec po full formate udrzi data

tu je relevantny vystup zo systemoveho logu (dmesg)

da sa s tym nieco robit ci len RMA?

zbehol som badblocks v read-only rezime a vysledok

este testnem v read-write rezime, co je vlastne full format a povrch v hdtune
snad to bude stacit na reklamaciu
kazdopadne aby novy USB kluc skapal po 4.5 mesiaci pouzivania povazujem za dost velky fail bez ohladu na to aky FS je na nom pouzity
