Hello, I have been reading all of the posts about .hma files and conversion to audio files and would like someone's advice/opinion. Unfortunately, I too made the mistake of using windows explorer to drag and drop files from the disk player. I have three disks with interviews on them. What's strange is that one of them can still be read by the disk player and I can hear my audio recordings. The other two give me the "Cannot play or record" message when I put them back into my disk player. I have not reformatted the disks or erased the files. When I connect the player to Sonic Stage, it shows space on the disk as being used, but I cannot get access to the files b/c they are not being recognized by Sonic Stage or my sony RH910 player. However, last night when I was putting the disks into the disk player I got a prompt on my disk player asking me if I wanted to convert them to audio files...I clicked no as I didn't want to convert them at all for risk of damaging them. Maybe I should have clicked yes? Is there any way to get to this menu again? It came up after I got the "Cannot play or record message" I have talked to someone at Sony (U.S. office, guy named Ed) who told me that they now have the software to try and recover files from disks. I can send my disks in and they can try but they only have a 50% success rate. I'm weary to send in the only disks I have with these files. The files are on my computer, but I now know that hma files transferred directly (without using SonicStage) cannot be converted into audio format. Does anyone have other ideas for me to try before I send these disks off to Sony? Again, SonicStage shows the disks as having data on them just will not list the files. I really need these files to finish my thesis! Please help! Thank you for your time!
