I was previously using SonicStage 4.2 on a Sony VAIO to copy original audio from HiMD recorded on an MZ-NH700 into WAV format. It worked OK, but my old VAIO was desperately slow and couldn't handle very long tracks. Recently I got a modern computer and at the time had no internet, so I tried installing SonicStage from some installation files copied off the VAIO (these were the installation files expanded by the SS installer from the files downloaded from the internet into a temporary folder, which SS deletes when the installation is completed). The installation appeared to install completely without error, and the program opened and could read and play the HiMD's and edit track names etc. I deleted a couple of tracks, then selected a track I wanted to copy and pressed the transfer button - SS immediately bleeped with the same sound it makes when deleting a track, and the track disappeared!!! Nohing was copied, and the deletion was instant, and there was no error message or any complaint from the program. Is there any way I can undelete the deleted file, or recreate the TOC? What happens when a track is deleted from a HiMD disc? Could I do anything with a Windows disc editor such as DiskEdit? Thanks for any help, MB-WBD PS - For the benefit of those interested in SonicStage errors, here is some more information about that aspect - I have since made a fresh install of version 4.3 from the internet using the SS installer, which works OK, but the above error seems very strange. The manual installation method worked when tested on the VAIO, but at least three things are different - software installed on the system at the time of download (does the installer check?); operating system language; and the VAIO system folder structure which was very heavily customised while the new one was default.
