Hi, the other day I scheduled chkdsk on my boot drive ("chkdsk c: /r") and it reported that it fixed a couple minor problems. I scheduled it to run again and it reported that it fixed the same problems. Basically, every time I run chkdsk it finds and fixes the same exact problem. Here is a sample log entry: Code: Checking file system on C: The type of the file system is NTFS. Volume label is SYS. A disk check has been scheduled. Windows will now check the disk. Cleaning up minor inconsistencies on the drive. Cleaning up 2 unused index entries from index $SII of file 0x9. Cleaning up 2 unused index entries from index $SDH of file 0x9. Cleaning up 2 unused security descriptors. CHKDSK is verifying Usn Journal...

I pulled the drive, installed it in my PC running XP, and scanned it with AVG and also Malwarebytes. Both scans came up negative. I also ran Chkdsk on both partitions on that drive but it didn't find anything wrong. However, that same disk error was found again when I reinstalled the drive into the original computer and ran Chkdsk. What's going on here? Why would chkdsk find and fix the same error with every boot, yet no errors show up when the drive is installed into a different PC? Thanks!
