Kiintolevyn <\/span>lukup\u00e4\u00e4t\u00e4 <\/b>voi helposti verrata aivoihin, koska se<\/span> lukee ja tulkitsee tietoja aivan kuten ihmisen aivot. T\u00e4m\u00e4 kiintolevyn osa my\u00f6s vastaanottaa uutta tietoa ja tallentaa sen my\u00f6hemp\u00e4\u00e4 k\u00e4ytt\u00f6\u00e4 varten. Aivomme toimivat samankaltaisesti: ne imev\u00e4t, tulkitsevat, tallentavat ja palauttavat mieleen ymp\u00e4r\u00f6iv\u00e4n maailman. <\/span><\/p>\n

Toinen yht\u00e4l\u00e4isyys <\/span>kiintolevyn lukup\u00e4\u00e4n <\/b>ja ihmisen p\u00e4\u00e4n v\u00e4lill\u00e4: niiden omistajat eiv\u00e4t voi toimia ilman niit\u00e4.<\/span><\/p>\n

Kiintolevy ei voi tehd\u00e4 mit\u00e4\u00e4n ilman t\u00e4ysin toimivaa lukup\u00e4\u00e4t\u00e4. My\u00f6s ihmiset ovat melko hy\u00f6dytt\u00f6mi\u00e4 ilman toimivaa p\u00e4\u00e4t\u00e4.

Kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4ysten (head crash) syyt<\/span><\/h2>\n

Mik\u00e4 siis <\/span>aiheuttaa kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4yksen<\/b>? T\u00e4h\u00e4n kysymykseen ei ole l\u00e4hes koskaan yksinkertaista vastausta, koska ongelman voivat aiheuttaa useat syyt tai syiden yhdistelm\u00e4t. T\u00e4ss\u00e4 muutamia yleisimpi\u00e4 <\/span>kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4ysten<\/b> syit\u00e4.<\/span><\/p>\n

Levyongelmat<\/span><\/h3>\n

Useimmat kiintolevyn lukup\u00e4iden ongelmat eiv\u00e4t ole lainkaan lukup\u00e4iden ongelmia. Kiintolevyn levyt, joille aseman tiedot on tallennettu, ovat itse asiassa monien <\/span>lukup\u00e4iden t\u00f6rm\u00e4ysten<\/b> perimm\u00e4inen syy. Kun <\/span>kiintolevyn lukup\u00e4\u00e4t <\/b>eiv\u00e4t pysty lukemaan levyj\u00e4, ne yritt\u00e4v\u00e4t usein lukea ja kirjoittaa toistuvasti, kunnes <\/span>kiintolevyn lukup\u00e4\u00e4 t\u00f6rm\u00e4\u00e4 levyyn<\/b>. <\/span><\/p>\n

Levyt voivat vaurioitua monesta syyst\u00e4. Kun niin k\u00e4y, se vaikuttaa <\/span>kiintolevyn lukup\u00e4\u00e4h\u00e4n <\/b>ja lopulta p\u00e4\u00e4tyy t\u00f6rm\u00e4ykseen. Joissakin tapauksissa ne yksinkertaisesti kuluvat ajan my\u00f6t\u00e4 ja pitk\u00e4aikaisessa k\u00e4yt\u00f6ss\u00e4. Kuluminen on levyjen yleinen ongelma ja siten <\/span>kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4ysten<\/b> yleinen seuraus.<\/span><\/p>\n

Joskus <\/span>kiintolevyn lukup\u00e4\u00e4n <\/b>toimilaitteen varsi (osa, joka todellisuudessa lukee ja kirjoittaa) vahingoittaa levyj\u00e4. Jos t\u00e4m\u00e4 komponentti vikaantuu, levyn magneettinen pinnoite voi tuhoutua. Ilman pinnoitetta mikroskooppiset p\u00f6lyhiukkaset alkavat laajentua ja aiheuttavat <\/span>kiintolevyn lukup\u00e4\u00e4n<\/b> vikaantumisen. <\/span><\/p>\n

Likainen levy<\/span><\/h3>\n

Puhuttaessa siit\u00e4, p\u00f6ly on yksi kiintolevyn pahimmista vihollisista. N\u00e4m\u00e4 pienet likahiukkaset voivat vaikuttaa harmittomilta, mutta py\u00f6riv\u00e4lle <\/span>kiintolevyn lukup\u00e4\u00e4lle<\/b> ne ovat yht\u00e4 hyvin j\u00e4ttil\u00e4isen heitt\u00e4mi\u00e4 kallionlohkareita. <\/span><\/p>\n

Kun p\u00f6lyhiukkasia p\u00e4\u00e4see aseman monimutkaisiin komponentteihin, ne koskettavat py\u00f6rimisen aikana <\/span>kiintolevyn lukup\u00e4\u00e4t\u00e4<\/b>. N\u00e4iden hiukkasten isku aiheuttaa l\u00e4hes v\u00e4litt\u00f6m\u00e4n <\/span>lukup\u00e4\u00e4n t\u00f6rm\u00e4yksen<\/b>. P\u00f6ly on tuhoisaa! <\/span><\/p>\n

Huolimattomuus<\/span><\/h3>\n

Jos kiintolevy\u00e4 ei k\u00e4sitell\u00e4 oikein, voi synty\u00e4 monenlaisia ongelmia. Erityisesti karavarret ja lukup\u00e4\u00e4t siirtyv\u00e4t helposti ep\u00e4kohdilleen, jos kiintolevy\u00e4 heitell\u00e4\u00e4n tai pahimmassa tapauksessa pudotetaan. Kun komponentit ovat ep\u00e4kohdallaan, lukup\u00e4iden t\u00f6rm\u00e4ys (head crash) ei ole pelkk\u00e4 mahdollisuus vaan varmuus.<\/span><\/p>\n

Mink\u00e4 tahansa fyysisen iskun aiheuttama vahinko voimistuu, jos lukup\u00e4\u00e4t liikkuvat iskun hetkell\u00e4. T\u00e4llaisissa tapauksissa <\/span>kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4ys <\/b>tapahtuu l\u00e4hes varmasti. <\/span><\/p>\n

Shoddy craftsmanship<\/span><\/h3>\n

Nykyaikaisten kiintolevyjen luotettavuudesta huolimatta on yh\u00e4 tapauksia, joissa viat vaikuttavat <\/span>kiintolevyjen lukup\u00e4ihin<\/b>. Mik\u00e4\u00e4n valmistusprosessi ei ole t\u00e4ydellinen, ja heikentyneet komponentit vaikuttavat suorituskykyyn kielteisesti. <\/span><\/p>\n

Valitettavasti jopa aivan uusissa levyiss\u00e4 on todenn\u00e4k\u00f6isesti muutamia vikoja, vaikka markkinoiden parhaissa levyiss\u00e4 on yleens\u00e4 alusta alkaen v\u00e4hiten ongelmia.\u00a0<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>

Ratkaisuja tietojesi pelastamiseksi<\/span><\/h2>\n

Onneksi on olemassa ennakoivia toimenpiteit\u00e4, joilla voit est\u00e4\u00e4 <\/span>lukup\u00e4iden t\u00f6rm\u00e4ykset<\/b>.<\/span><\/p>\n

Tutki tuote<\/span><\/h3>\n

Puhuimme juuri huonosta valmistuslaadusta, joka johtaa <\/span>kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4yksiin<\/b>. V\u00e4lt\u00e4 t\u00e4llaiset <\/span>lukup\u00e4iden t\u00f6rm\u00e4ykset <\/b>tutustumalla tuotteeseen <\/span>ennen <\/span><\/i>kiintolevyn ostamista.<\/span><\/p>\n

Selvit\u00e4, mit\u00e4 valmistajia kannattaa v\u00e4ltt\u00e4\u00e4 ja mitk\u00e4 valmistajat tekev\u00e4t luotettavia kiintolevyj\u00e4. Lue yksitt\u00e4isten mallien arvosteluja \u00e4l\u00e4k\u00e4 unohda ottaa huomioon kapasiteettia. Jos k\u00e4yt\u00e4t aikaa perusteelliseen selvitysty\u00f6h\u00f6n, l\u00f6yd\u00e4t erinomaisen kiintolevyn haluamaasi hintaan ja tietojen tallennuskapasiteetilla.\u00a0<\/span><\/p>\n

Ennaltaehk\u00e4ise suojellaksesi<\/span><\/h3>\n

Kuten monessa muussakin asiassa el\u00e4m\u00e4ss\u00e4, ennaltaehk\u00e4isy on avainasemassa.\u00a0<\/span><\/p>\n

Kiintolevy on kehittynytt\u00e4 tekniikkaa, ja sit\u00e4 tulee k\u00e4sitell\u00e4 \u00e4\u00e4rimm\u00e4isen huolellisesti. Jos et kohtele kiintolevy\u00e4si kunnioittavasti, riskeeraat tietojesi menetyksen.\u00a0<\/span><\/p>\n

Pid\u00e4 kiintolevyst\u00e4si hyv\u00e4\u00e4 huolta. \u00c4l\u00e4 anna tietokoneesi likaantua ja pid\u00e4 p\u00f6ly poissa aseman sis\u00e4lt\u00e4. Jos p\u00f6ly\u00e4 p\u00e4\u00e4see sis\u00e4\u00e4n, l\u00e4mm\u00f6n haihtuminen heikkenee. T\u00e4m\u00e4 lis\u00e4\u00e4 aseman ylikuumenemisen todenn\u00e4k\u00f6isyytt\u00e4. Viile\u00e4 asema toimii tehokkaasti eik\u00e4 rasitu.<\/span><\/p>\n

T\u00e4rkeint\u00e4 on k\u00e4sitell\u00e4 kannettavaa tietokonetta varoen. \u00c4l\u00e4 paiskaa tietokonetta ymp\u00e4riins\u00e4 \u00e4l\u00e4k\u00e4 kanna kannettavaa syliss\u00e4si ilman varmuutta siit\u00e4, ettet pudota sit\u00e4. Se voi olla haastavaa n\u00e4iden laitteiden kannettavuuden vuoksi, mutta yrit\u00e4 parhaasi! Monet <\/span>kiintolevyn lukup\u00e4iden t\u00f6rm\u00e4ykset <\/b>voidaan helposti v\u00e4ltt\u00e4\u00e4 pit\u00e4m\u00e4ll\u00e4 kiintolevyst\u00e4 yksinkertaisesti parempaa huolta alun alkaen. <\/span><\/p>\n

Varmuuskopioi ennen kuin on liian my\u00f6h\u00e4ist\u00e4<\/span><\/h3>\n

Kiintolevyjen lukup\u00e4\u00e4t t\u00f6rm\u00e4\u00e4v\u00e4t<\/b>. Niin vain k\u00e4y. Mutta ennen kuin <\/span>lukup\u00e4iden t\u00f6rm\u00e4ys <\/b>tapahtuu, tietojesi suojaamiseen on keinoja. K\u00e4yt\u00e4 ulkoista kiintolevy\u00e4 tai pilvipohjaista tietojen tallennusratkaisua tietojesi varmuuskopiointiin. <\/span><\/p>\n

Varmuuskopioi s\u00e4\u00e4nn\u00f6llisin v\u00e4liajoin varmistaaksesi, ett\u00e4 varmuuskopiolevyllesi on aina tallennettu tuore kopio tiedoistasi. Laadi siis varmuuskopiointiaikataulu ja noudata sit\u00e4!\u00a0\u00a0<\/span><\/p>\n

Seis!\u00a0<\/span><\/h3>\n

Jos uskot, ett\u00e4 <\/span>kiintolevysi lukup\u00e4\u00e4 <\/b>on t\u00f6rm\u00e4nnyt, lopeta kaikki tekeminen ja astu pois tietokoneen luota. T\u00e4m\u00e4 on vaikeaa, sill\u00e4 luonnollinen reaktiomme t\u00e4llaisina hetkin\u00e4 on joutua paniikkiin ajatuksesta menett\u00e4\u00e4 tietomme ja yritt\u00e4\u00e4 jollakin tavalla \"korjata\" ongelma. <\/span><\/p>\n

Mik\u00e4 tahansa jatkotoimi riskeeraa kiintolevysi korjaamattoman vaurioitumisen. Ja lis\u00e4vauriot voivat est\u00e4\u00e4 sinua koskaan saamasta tietojasi takaisin. Vastusta siis kiusausta ja astu pois koneen luota!\u00a0<\/span><\/p>\n

Hakeudu ammattilaisen puoleen<\/span><\/h3>\n

Aina kun kiintolevysi kanssa on ongelmia, johtuivatpa ne <\/span>lukup\u00e4iden t\u00f6rm\u00e4yksest\u00e4<\/b> tai eiv\u00e4t, pyyd\u00e4 neuvoa ja apua p\u00e4tev\u00e4lt\u00e4 tiedon palautuksen asiantuntijalta. <\/span><\/p>\n

Tiedon palautuksen asiantuntijoilla on ty\u00f6kalut ja tekniikat ongelman arvioimiseen, ratkaisun suunnitteluun ja tietojesi palauttamiseen nopeasti!<\/span><\/a>\u00a0<\/span><\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"A hard drive head can easily be compared to a brain, because it reads and interprets data just like human brains.
