USB-muistitikun käyttö

[Pendeli]

Sain joitakin vuosia sitten tuttavalta muistitikun jonka sisällön siirsin onnistuneesti Ubuntukoneeseen.
Alkuperäinen tiedosto oli kuvatiedostoja Windowskoneelta.
Nyt ajattelin ottaa saman tikun muuhun käyttöön mutta se ei tule näkyviin missään USB-portissa eikä
toisessa koneessakaan.
En muista tehneeni mitään erikoisempia temppuja tikulle silloisen kuviensiirron jälkeen.
Voiko tikun alustaa niin että se ei enää näy missään ja saako sen uudelleen toimimaan? Vai onko se yksinkertaisesti vain vioittunut?

[nm]

Jos ei näy lsusb:n listauksessa eri porteissa ja eri koneilla katsottuna, tikku on aika varmasti entinen.

Kannattaa siis verrata lsusb:n listauksia tilanteesta kun laite on irti siihen kun se on kytketty USB-väylään.

[startx]

Useamman kerran on käynyt silleen, kun on useampaa tikkua rumpannut koneessa, niin lakkaavat näkymästä, mutta kun koneen käynnistää uudestaan, niin alkaa taas toimimaan.

[juyli]

Useamman kerran on käynyt silleen, kun on useampaa tikkua rumpannut koneessa, niin lakkaavat näkymästä, mutta kun koneen käynnistää uudestaan, niin alkaa taas toimimaan.

Olet siis ratkaissut ongelmasi [Ratkaistu], sinne, minne  se kuuluu...
Olethan irroittanut laitteen? XFCE-työpöydällä olisi vaihtoentoina "Irroita laite" tai "Poista asemasta".

[Pendeli]

Saman muistitikun ongelma tuli taas esiin. En usko että tikku itsessään on viallinen.

32-bittisellä koneella lsusb listaus näyttää tikun.
Tikku näkyy myös saman koneen työpöydällä lukittuna kryptattuna levynä ja pyytää salasanaa lukituksen avaamiseksi. Normaalisti tällaisissa tapauksissa käyttämäni salasana ei kelpaa eikä myöskään koneen salasana.

Tikku ei näy 64-bittisessä koneessa ollenkaan.
Molemmissa koneissa Ubuntu 18.04.


Onko eroa kummalla koneella (32/64) kryptaus on tehty?  Molemmissa samat salasanat käytössä samoinkuin yleisiin tarkoituksiin varatut salasanat. Jos tikku kryptattu 64- bittisellä koneella niin kuinka koko levyä saa edes näkyviin?

Saman muistitikun ongelma tuli taas esiin. En usko että tikku itsessään on viallinen.

Eli oikea salasana ei ole enää tiedossa?

Jos tikulla on tärkeää dataa, jota ei ole varmuuskopioitu muualle, ainoa keino tiedostojen esiinsaamiseen on oikean salasanan löytäminen tai arvaaminen.

Jos taas tikulla ei ole säilytettävää dataa, ja haluat vain saada sen uuteen käyttöön, poista nykyinen salattu osio Levyt-ohjelmalla tai Gpartedilla. Luo sitten tikulle uusi osio tarkoitukseen sopivalla tiedostojärjestelmällä.

Tikku ei näy 64-bittisessä koneessa ollenkaan.
Molemmissa koneissa Ubuntu 18.04.

Jos tikku ei näy lsusb:n listauksessa, vika on laitteistotasolla, eli USB-portti voi olla viallinen tai tikku ei vain ole yhteensopiva koneen USB-kontrollerin kanssa.

Kernelin lokin lopussa saattaa näkyä asiaan liittyviä virheilmoituksia sen jälkeen, kun tikku on kytketty koneeseen. Lokin saat listattua päätteeseen komennolla:

Koodia: [Valitse]

dmesg

Onko eroa kummalla koneella (32/64) kryptaus on tehty?

Linuxin suoraan tukemat levysalaukset toimivat bittisyydestä riippumatta. Ongelman kuvauksesta ei tosin vielä selvinnyt, mikä salaustekniikka tikulla on käytössä

Molemmissa samat salasanat käytössä samoinkuin yleisiin tarkoituksiin varatut salasanat.

Tikun kryptatun osion salasana ei riipu järjestelmän salasanasta. Toki se voi olla sama kuin kirjautumissalasanasi, jos olet sellaisen asettanut kryptauksen yhteydessä.

[Pendeli]

Jotain outoa siinä kai on. Yhteensopivuusongelma tms. Kaikki muut tikut toimivat molemmilla koneilla. Tämä kyseinen tikku ei ollenkaan  koneella no 1 mutta näkyy koneella no 2 ja vaatii salasanan auetakseen. Pitää ruveta kaivelemaan salasanavarastoja.

dmesg -komento antaa pitkän litanian jonka loppupäästä liitteenä pari pätkää jos niistä löytyy jotain infoa:

Liittyykö tämä virhe johonkin toiseen levyyn, eli mihin laitteeseen /dev/sdb viittaa?

[ 2549.122886] usb 3-10: USB disconnect, device number 5

Tuleeko USB disconnect -viesti silloin, kun kytket tikun koneeseen, vai tikun irrotuksen yhteydessä?
Tarkista avaamalla työpöydälle kaksi päätettä ja aja dmesg ensimmäisessä niistä. Kytke sitten ongelmatikku koneeseen. Aja dmesg toisessa päätteessä. Vertaa listausten loppuosaa. Mitä uusia rivejä toiseen dmesg-listaukseen on tullut tikun kytkemisen jälkeen?

Tässä alkuunsa pätkiä dmesg-komennon tuloksista kun tikku ei ole koneessa

Listauksessa näkyy kuitenkin useassa kohtaa tikku mainittuna.
Listauksen tiedot pätkiä sieltä täältä, ei siis koko listausta mukana.

[Pendeli]

Tässä pitempi pätkä tikku liitettynä. Tikku ei näy koneella.

Jouduin poistamaan paljon tekstiä koska sivusto ei hyväksynytkaikkea.

En oikein myöskään tiedä mikä olisi oleellista laittaa esille.

Tässä pitempi pätkä tikku liitettynä. Tikku ei näy koneella.

Okei, tämä on siis nyt siltä koneelta, jossa tikku ei ole toiminut lainkaan? Nuo virheet viittaavat selvästi laiteongelmaan, eli joko tikussa tai USB-väylässä on vikaa. Jos tikku toimii toisella tietokoneella paremmin, vika lienee ongelmakoneen USB-portissa tai USB-kontrollerin ja tikun epäyhteensopivuudessa.

Kannattaa kuitenkin tutkia lokiviestejä myös sillä koneella, jossa olet saanut tikun esiin ja järjestelmä pyytää salasanaa sen avaamiseen.

Yksi metallirunkoinen usb-tikku ei näkynyt tietokoneelle. Mutta kun sitä heilutteli vähän, niin sitten sen sisältö tuli näkyviin koneella. Tuli vain mieleen, että ihan tuollainen fyysinen asiakin voi saada tikun toimimattomaksi. Harmi, kun se tikku vaikutti muuten tosi kestävältä. En enää uskalla tärkeitä tiedostoja sellaisiin vastaavanlaisiin tallettaa.
