Hi all. Long story short, my time machien ahs been acting strange thought of erasing, then starting over with a fresh hd. This is a three tb sigate external connect I think fire wire, it's not a standard usb port. However first it's now showing as mounted, now it is mounted but it won't let me erase volume failed, media kick won't support the space or something strange like that. Is there a third party app someone can help me find that just fixes this? I just want to keep using it, don't want to spend more money if i can't.
