I did what you told me to do and I again removed the filenames from the debuglog.
Again no errors seem to appear in the log but the crash keeps occurring all the time.
You are right that disk H: seems to be causing the error and it's correct it is a 3TB disk formatted with FAT32 since I have a special need for the disk.
chkdsk finds no problems whatsoever:
chkdsk /f h:
The type of the file system is FAT32.
