Hi All,
Just thought I’d share this data-point here since I wasn’t able to find this information, and essentially had to trial-and-error my way to a solution.
Last night I was using the Qu-Drive feature on a Qu-32 to record 18 tracks of multitrack to a sandisk external SSD. A power interruption killed the board before I was able to stop the recording, corrupting the files. I was sure I had lost the data (which in this case was for a purely volunteer gig with the recording as a bonus, not a primary goal. So not the end of the world). Someone mentioned to me that VLC might be able to read a file even if it were corrupted, so I should try and recover it that way. Well, that didn’t work, but once I started reading, searching, and trying different things, my hope to recover these increased, and eventually I was able to do so using Audacity’s Raw Data import tool.
First, I used the ‘chkdsk’ command in windows (through cmd.exe) to let windows find any data that wasn’t properly stored/formatted/etc. Because the disk for me was the D: drive, I used [chkdsk D: /f] without the brackets, which made my previously 512 Byte large corrupted files now a seemingly correct size. (around 800MB each) I used Audacity to try and open them, but it was still unable to, and VLC gave me audio, but it was clearly random digital distortion. I eventually found that using the following settings resulted in my original audio, and I was able to then use Audacity to export them as Wav files again, ready to be dropped into Protools!
Encoding: Signed 24-bit PCM
Byte Order: little-endian
Channels: 1-channel(mono)
start offset: 512 Bytes
Amount to import: 100%
Sample Rate: 48000 Hz
Hopefully this will be useful to someone somewhere so they don’t have to hunt and peck those settings!
