Hallelujah!!

CHKDSK can be run in, essentially, three modes:

READONLY —— CHKDSK C: (or other drive)
NORMAL FIX —- CHKDSK C: /F (or other drive)
EXTENDED FIX — CHKDSK C: /R (or other drive)

The latter two modes require a reboot if the drive or partition that they’ll be running on has locked files (e.g. the pagefile), so if you just want to find out if you NEED to fix anything, simple run it in READONLY mode. If it doesn’t complain that there are issues that you need to correct, then you don’t have to run one of the more extensive scans.

Using the /F parameter will run a 3-step process to fix files, indexes and free space. Using the /R parameter will run a 5-step process which also addresses bad sectors on the disk, and looks harder at the Master File Table (MFT).

Så efter at have brugt tidligere nævnte programmer og vejledning og konstateret at alle filer var til stede på disk O, så var det bare at at køre CHKDSK O: /F – fra ‘Run’ i startmenuen og checkdisk fik rettet i partitions tabellen m.v. og alt er nu godt igen – det må vist fejres med en lille G/T…

note: husk at ændre boot order…
