I forgot the likelikhood that the error would happen after cycling through the all disks which could cause file to be overwritten.
If there is some down time, I would like to try adding a line to check if file exist before generating the name, you can find the script in ~a- onl/scripts/dev, it is called fname.tcl, just need to copy the line in bobfile. I did not managed to test it yet.
So I think if there is down time : - copy bobfile.tcl into another file with a name to keep as back up - add the line to check and change file name if it exists - generate a fake coda file by doing a touch filename which is supposed to be create -start a run and check the file was created with the other name -try another run to make sure it runs normally -if it works leave the script as is -if it does not work remove the lines or copy back the backup file as bobfile.tcl
