The best way to predict how long CHKDSK will take to run on a given volume is to actually do a trial run in read-only mode during a period of low system usage. Care must be taken using this technique, however, for three reasons:

• Read-only CHKDSK will abort before it completes all three phases if it encounters errors in earlier phases and is prone to falsely reporting errors when in read-only mode. That is, CHKDSK may report that a disk is corrupted even when there is no real corruption present. This can happen if NTFS happens to modify areas of the disk on behalf of some program activity that CHKDSK is examining at the same time. To verify a volume correctly, the volume must be in a static state, and the only way to guarantee that state is to lock the volume. CHKDSK only locks the volume when /F or /R (which implies "F") is specified. Thus, you may need to run CHKDSK more than once to get it to complete all stages in read-only mode.

• System load and whether CHKDSK is running online or during the Windows NT boot sequence can impact the time required to run CHKDSK. CHKDSK is both CPU and disk intensive. Which factor becomes the bottleneck will depend on the specific hardware scenario, but, if heavy disk I/O or high CPU usage is going on concurrent with a read-only CHKDSK, inflated times will result. Also, Autochk.exe runs in a different environment than Chkdsk.exe. While running CHKDSK through Autochk.exe affords exclusive use of CPU and I/O resources to CHKDSK, it also deprives CHKDSK of the benefit of virtual memory. Thus, while Autochk.exe would usually be expected to run faster than Chkdsk.exe, systems with relatively low amounts of RAM may see longer times for Autochk.exe than for Chkdsk.EXE.

• Fixing corruption adds to the time required. A read-only CHKDSK can complete only if no significant corruption is found. If a disk suffers only minor corruption, the time to fix the problems will be only slightly longer than that required for read-only CHKDSK. But if there is major damage, as might result from a serious head-crash or other major hardware failure, the time required to run CHKDSK can increase in proportion to the number of files damaged. In extreme cases, this could more than double the time required for CHKDSK.
