I have a collection of Sound Effects samples, totalling about 700GB. These are not only WAV and AIFF files, but also the legacy Sound Designer II files (SD2). Most of these SD2 files are without extension, and as the data has at some point been stored on a PC, the system forks are missing. When working on the samples to restore the system forks, and converting the SD2/AIFF files to WAV files, my mac volume gets corrupted somewhere along this process. I have tried to change hard disks, but the same problem occurred.
How is this possible?
Now the volume wouldn't mount, and I am unable to fix it in disk utilities. Please see screenshot.
Are there more advanced pieces of software which can fix the volume/partition/file error(s)?
