So the other night I was transferring some stuff to my external which is attached to my AEBS. Actually I was sending stuff to it from both my Mini and my Macbook. Well My AEBS shut itself off, which is does from time to time when it has to do a lot of work, but I usually just turn it on and it works fine. This time it told me there was a problem with one of my disks. I connect the disk locally, it wont mount. I run Disk Utility, and try to verify or repair the disk and I get: Volume check failed. Error: Filesystem verify or repair failed. So what am I to do? I would really like to get the data off of this drive, so just formatting it isnt an option.
