What to check after computer shut off due to power outage.

Chkdsk /r is similar as chkdsk /f, with the exception that chkdsk /r will examine for information positioned on dangerous sectors.  See THIS.

Usually, customers run chkdsk /f on SSDs, pondering that chkdsk /f will carry out the identical capabilities…I actually run chkdsk /r on my SSDs and I’ve discovered recordsdata on dangerous sectors after I run it.  The issue with dangerous sectors is that recordsdata on dangerous sectors or that are marked as being on dangerous sectors…can’t be learn and due to this fact might not reply as anticipated by Home windows.

Operating a chkdsk with out both the /f or the /r parameter…is a complete waste of time…doing so ends in a read-only model that does nothing in any respect to any recordsdata which can be broken or on dangerous sectors.  I’ve by no means run the read-only model of chkdsk…I run it it to aim to restore, to not simply inform me that there are issues.

I strive to not care about some issues that are posted every day on the Net and which do not logically make sense.  Such are the myths which can be perpetuated about operating the chkdsk instructions.

There are two several types of dangerous sectors…errors on the file system (which will be overcome generally through chkdsk or by reformatting that partition)…and a few dangerous sectors on the drive itself (which might point out a {hardware} downside with the drive itself).  I think about it clever to not mechanically assume that dangerous sectors reported by Home windows…point out a defective onerous drive…such (in my expertise) might solely point out a file system downside and any consumer asserting mechanically that the drive must be substitute…simply is just not making a legitimate suggestion.

There are separate onerous drive diagnostics which must be run when one needs to affirm or refute the concept that the drive, not the file system, is the issue.  These, together with the SMART information for the drive, are a extra dependable method for assessing the well being of the drive (not the partition or file construction).

Any consumer not making routine backups…is leaving herself/himself weak to inconveniences of assorted varieties…if they don’t seem to be making routine backups.  If I discover dangerous sectors on the file system…I simply restore a backup of my Home windows partition (takes lower than half-hour) and the method of restoring the backup eliminates the file system issues which I’ve created/encountered.
