Plutselig korrupt disk

[Makky]

Har en disk her som plutselig ikke ville boote lenger.

 

Får bare opp "NTLDR is missing".

 

Partition table sier NTFS

Boot sector sier FAT12

 

Hvilket verktøy anbefales for å fikse dette?

F.eks (hvis du har Windows XP)

 

 

Insert the Windows XP bootable CD into the computer.

When prompted to press any key to boot from the CD, press any key.

Once in the Windows XP setup menu press the "R" key to repair Windows.

Log into your Windows installation by pressing the "1" key and pressing enter.

You will then be prompted for your administrator password, enter that password.

Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.

 

copy e:\i386\ntldr c:\

copy e:\i386\ntdetect.com c:\

 

Once both of these files have been successfully copied, remove the CD from the computer and reboot.

Under ligger logg fra testdisk.

 

Kjørte også en scan med testdisk, og jeg har mulighet for å endre partisjonstypen til HPFS-NTFS fra FAT12. Er dette noe å teste eller finnes det en annen løsning?

Problemet er at partisjonen er på bærtur. Den blir gjenkjent som FAT12.

93GB stor partisjon vises som 10MB.

 

Så å bare legge til filen vil ikke funke dessverre.

Er det der hvor jeg kan forandre partisjonstypen?

[Makky]

Backup boot sector er bad den også.

Vil det funke med å velge "Rebuild BS"?

 

 

[Dr.Gonzo]

Prøv å koble disken av og på noen ganger og restarte for å se hva som skjer. Det hender at dette er nok til at det ordner seg.

[sdhild99]

Vær OBS på at denne feilen (og lignende 'harddiskfeil') også kan oppstå grunnet korrupte minnebrikker

[Makky]

Disken er testet på flere maskiner, og ram er ikke problemet.

[Hårek]

Du bør vel prøve Rebuild. Antar det tar en god stund.

Du bør vel prøve Rebuild. Antar det tar en god stund.

 

Starter "Rebuild BS" etterpå.

Tid har jeg heldigvis nok av

[Makky]

Etter å ha kjørt "Rebuild", er jeg tilbake der jeg starta.

Fortsatt står det bad på boot og backup.

 

Trenger flere tips.

[Phyltre]

Vel har selv en gammel laptop med liknende symptomer. Ingen vits i å gråte over spillt harddisk. For sent å ta backup når man har vært så lat å ikke tatt backup før.

 

I mitt tilfelle har jeg avskrevet hele laptopen da disken er fubar. Ikke gidder jeg heller driver med hjertekirurgi på lappisen min heller.

[wiberos]

Backup boot sector er bad den også.

Vil det funke med å velge "Rebuild BS"?

 

 

 

Det er disk nr2 du kontrollerer her.

Du kan ikke rebuild når du ser at det er noe galt med geometrien på denne disken, ikke sant?

Hvor mange heads har du på den?

 

Hva med disk nr 1. Har du samme problem der og?

 

 

Uansett:

kanskje du du må starte med å slette partitioner på den, velg riktig geometry, recover partitioner for så å ta det etter det?

[Makky]

Ja er disknr. 2 som er problemdisk.

Disk 1 er i orden, den jeg har bootet med.

 

Skal geometrien settes til 255? Tror den viste 240 nå.

Hvor ser jeg hvor mange heads det er?

[wiberos]

Hvis disk nr1 er = disk nr 2 , så vil det best være å:

 

kjøre analyse for disk 1, slik at du ser hvordan den er, få en forståelse av hva er hva, før du forandrer på heads.

Mulig det er partitioner på denne disken som er bananas.

 

 

Er det Vista eller Win7 på noe andre disker som brukes som boot?

Endret 30. januar 2009 av wiberos

[Makky]

Hmm, litt uklart forklart av meg.

 

Det er to fysiske disker i maskinen.

Hver av dem skal ha 1 partisjon.

 

Det er disk 2 som har problemer, hvor partisjonen blir identifisert som fat12.

 

Begge diskene inneholder XP.

Diskene er like store 100GB, bare to forskjellige produsenter.

Endret 30. januar 2009 av Makky

[wiberos]

Ja det er kjempe bra at de er like.

 

Med å kjøre analyse på den som fungerer,....du skal ikke reparere eller forandre på noe, vil du kunne sammenligne verdiene som vises på den på disk 2.

Er verdien på heads 240 eller 255 på den andre?

 

Da har du noe å forholder deg til, når du skal reparere den andre.
