Masta Blasta,

I'm willing to bet what you're seeing isn't index corruption, but a byproduct of our fix for one of the other annoying bugs:

8.6 Release Notes wrote:

- System time changing due to travel no longer necessitates a rescan of indexes

The delta scans on files are triggered based on a check of the "Modified Time" metadata value which was - previous to 8.6 - calculated in the machine's local time.

If that time zone was to change (for example: if you happened to travel between time zones), the modified time value would be inaccurate and X1 Search would re-index those items.

The solution for that bug was to change the calculation of the Modified Time to be in the UTC time format, which never changes.

The downside of that fix is that every item in your index must have that calculation performed on it. This requires removal and re-indexing into the index, as most metadata values are calculated upon ingestion into the index.

In order to avoid the issue of everyone who updated to 8.6 having their index be automatically deleted and rebuilt from the ground up, we elected to allow everyone to preserve their existing indexes - however, if you elected to keep those existing indexes the modified time re-indexing issue is still present.

Delete and rebuild your indexes, and I'll bet this problem is solved for you.

thank you cscott for the detailed explanation. unfortunately this is occurring on a new installation of X1 and on machines that do not change time zones.like other versions before, it is always the items from drive c: that get lost, the index retains items from other drives.

also seeing the same issue as SoCalScott, X1 is running a full reindex of the computer after every boot.
