looks like you have some problems with HDD and/or databases also.
it speac that cant delete file, cant create files. also errors with databases.
check your disk with checkdisck tool in windows for errors, may be just errors in file table of disk.
Update: yes, the hard drive took a dump. Chkdsk is not even finishing on it, and the Seagate Seatools check fails as well. It will need to be replaced.
