You are very lucky in being able to complete the rebuild within 5 - 6 days. I have had basically similar problems as you. However, co-incidentally or otherwise, since a Windows 11 update last weekend, even re-build is now effectively stuffed and will not work. I have tried the rebuild countless times over the past few days, all without success, as they either totally stall or progress at a minute rate. To give some examples, the rebuild had indexed 7 files after 3 hours, or 5 files after 9 hours (left on overnight with nothing else running, or this morning 16 files after 3 hours. At times this has meant that if the same rate of rebuild continued, it would take something like 900 years to complete - somehow I don't think that either I or my computer will last that long. Based on the continuing slow continuing saga this morning, it is going to take something like 56,000 hours to complete or more than 6 years. This Microsoft issue has become farcical. John
