These errors are cause by "Everything" trying to read the NTFS USN Journal on a FAT32 volume.
FAT32 does not support USN Journals.
In the NTFS options page, "Everything" can try to read USN Journals on FAT32 drives if you had check media for the F: drive unchecked and tried to check it.
If you would like "Everything" to index this volume you will need to convert it to NTFS first.
See http://support.microsoft.com/kb/307881 for more information.
Kodak's crappy “DC File System Driver” running in the background seems to be the culprit.
The memory card belongs to an older digicam which isn't NTFS compatible, and 'tupid me forgot to eject the reader prior to testing the newest beta of Everything.
Thanks a lot for the prompt response and for making this great tool available as freeware!
I ran into something similar (couldn't add C or D drive despite their being NTFS and working previously). Turned out to be the same sort of storage driver issue, in my case a printer which had some small flash drive showing up in my devices. I disabled the disk from the Device Manager and suddenly everything is back to normal. Yay.
