Hi all,
anybody seen or heard of this scenario?
I did a chkdsk /r on my XP partition from within XP and it checked the disk
at the next boot.. For about 10 files, I got a message saying "Windows replaced bad clusters in file xxxxx"

The interesting thing is when I checked the location later, all of these files were files in folders
that I had compressed using NTFS compression ("compress contents to save disk space" in file/folder
properties). Coincidence? Limitation or bug? Seems odd, the files were in different folders, etc, but they
all shared that compressed attribute.

For now I'm running Windows 10 chkdsk /B (it's a dual boot machine) to see if it says anything further about
the volume

There is some similar events reported on the internet but nothing conclusive that I could see.

Don't confuse folder placement with byte location on the drive (sectors and cluster). How old is the drive? Might want to keep an eye our for additional occurrences like this, but for now I wouldn't think it was too much to worry about.

It's a 250GB Seagate SATA drive about 12 years old. After the above incident, I ran the latest Seagate tools (long scan) and
Chhkdsk /B in Windows 10. Seagate tools returned with "Pass" and the Chkdsk /B on the XP partition returned with the following:

Stage 4: Looking for bad clusters in user file data ...

131696 files processed. File data verification completed.

Stage 5: Looking for bad, free clusters ...

476517 free clusters processed. Free space verification is complete.

Windows has scanned the file system and found no problems.
No further action is required.

18883552 KB total disk space.
16708736 KB in 88510 files.
33120 KB in 11548 indexes.
0 KB in bad sectors.

Also, Chkdsk /r on the Windows 10 partition ended clean. I will keep an eye on it.

One of the XP files that received an error (Windows replaced bad clusers...) was in a dll file in \Windows\WinSxS
Does it even matter ? Not much in the way of updates for XP any more.
