This has happened to me when I KNOW that the dictation was downloaded and "lost". Like you, I do everything within my power to "find" the dictations rather than go the doctor. I have 12 dictactors using the system and I am the MT coordinator. I have always found the dictations using the help of IS department. We have wave files and they are usually sitting on the hard drive of the PC, C drive, not the network. Sometimes we really have to search for the missing voice files but if the doctor downloads them and you are searching on the correct PC you will find them on the C drive, at least that is my experience. Make sure you are searching on the correct PC. We have several PCs that are used in six offices so this can be a challange for that reason. We have one doctor who is never sure which PC he downloaded on or if he even used his password or just downloaded under another person logged in at the time.
