Win 7, Home Premium, 64 Every time I reboot my machine I get a volsnap Event 25 error: "The shadow copies of volume C: were deleted because the shadow copy storage could not grow in time. Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied." and all restore points are deleted. I can successfully create restore points. C: drive has over 60gb free and protection for C: has 3.35gb max usage. I have tried turning system protection off and on and gotten the following errors for both off and on. It did turn off and back on. Not sure whether System Volume Information is corrupted or what but would appreciate some help here. This started when I had a data drive (not same drive as C) begin to fail and cause problems with windows booting. Once I replaced the data drive Windows booted ok, but with some odd problems including this. I am also experiencing a Kernel-Event Tracing Event 3: "Session "UBPM" stopped due to the following error: 0xC0000022" and a companion "Session "Eventlog-Security" stopped due to the following error: 0xC0000022" which I was going to start another thread on. Everything else seems to be working ok, knock on wood. Thanks for your help!
