"Phase 3: Checking security descriptors
During its third pass, CHKDSK displays a message that tells you that CHKDSK is verifying security descriptors and, for the third time, displays "percent completed," counting from 0 to 100 percent. During this phase, CHKDSK examines each security descriptor that is associated with files or directories that are on the volume.

Security descriptors contain information about ownership of a file or directory, about NTFS permissions for the file or directory, and about auditing for the file or directory. The "percent completed" that CHKDSK displays during this phase is the percentage of the volume's files and directories that have been checked. CHKDSK verifies that each security descriptor structure is well formed and is internally consistent. CHKDSK does not verify the actual existence of the users or groups that are listed or the appropriateness of the permissions that are granted."

Mikä sitten on aiheuttanut vian?
Virtakatkos, koneen sammuttaminen väärin, käyttiksen kaatuminen vai kiintolevyn vika.
Sehän siinä kiinnostaa varmaankin eniten, onko kiintis simahtamassa.
Voisi ajaa kiintolevyn valmistajan testiohjelman.
Tuosta korjaustoimenpiteesta, minkä chkdsk oli suorittanut en nyt osaa sanoa mitään. Pitää jatkaa opiskelua!
