Can't access second hard drive Mac

I'm running mp3tag app on a Mac OS X. My musics are on my second hd and I can't access these files. I already tried creating a shortcut on my main hd but it didn't work out.
Does anyone know how to solve this?

Thanks

You have to make sure that the second hd is visible for the app.
Also, you have to set the access rights so that the folders are accessible.

Thanks for your help, Ohreking.
The access rights we're already right.
But I don't know how to make sure that the second hd is visible for the app, can you walk me through, please?

No, sorry, no idea. Windows only.
So you have to consult the Apple help to find out how to attach another drive in such a way that it is treated like a built in one.

I see. I think it's already like a built in one, because I had put it in the place of my CD drive and it's connected to the SATA cable.

I'm not sure, but maybe the problem is with the Wine app. I already looked on the configs trying to find something that may help, but nothing.

Anyway, thanks again for your help and sorry for the english.

After searching for a while, I discovered the solution:
the externals HD are under Z:\volumes
So easy!
Thanks ohrenkino!
