Chkdsk found errors - what does it mean?

[DennisInOz]

I am having trouble with incomplete Windows backup in W10, backing up to an external Toshiba 1TB drive, and the error message recommended running CHKDSK. No problems were found with the external drive, but when I ran chkdsk /f /r on my HDD, the following log was generated. Can someone tell me what it means, and am I facing impending HDD problems?

It is a bit confusing because it at one point, it says there is not enough space to replace bad clusters, but then it reports 83835844 KB (83.8GB) of space available.

BTW, you don't need the /f when use /r. If you enter chkdsk /?, that lists all the available options and you see that /r "implies" (includes) /f.

If me, I would run Windows Disk Cleanup on the drive, then run chkdsk /r again and see what happens.

You might also try SeaTools Diagnostics. While developed by Seagate, it works with all brand drives. If it also finds errors that cannot be corrected, then I would not that drive for critical data storage without having another backup somewhere else.
