First off, thanks to everyone offering advice here - I am relatively new to OS X and need the advice. I have a portable FireLite Smartdisk HD that is connected to my MBA via a USB2 wireless hub. I have run it direct to the MBA, through the hub, and had no issues whatsoever for 7 months. The drive is 14 months old. And yes, the warranty is for 12 months. (Looking for a portable HD? Don't buy this one.) The drive is less than 25% full. It is in FAT32 format. It primarily serves as a backup for some non-critical files. It failed last week. Crash, boom. The drive would not mount, and made a loud "clicking" noise when powered up. I (mistakenly) assume the drive is toast, say a little prayer for the POS, and smiled that I am not so stupid as to forget to backup my data. Here's where it gets weird... (cue spooky background music) The next time I reboot, I forget the drive is still attached. IT MOUNTS. No clicking. Even spookier, DATA IS THERE. Figuring I am simply inept at computer, I just guess that maybe I was wrong and it is okay. Over time (and successive reboots) the drive continues to mount. Sometimes the data is there. Sometimes the data is not accessible. On a few more occasions, the drive completely fails to mount and reverts back to making that loud clicking noise. So.. What do I do? Is this a HTF+/Fat32 thing? I would figure loud clicking from a drive speaks to a hardware issue, but in my limited knowledge hard drives either work or fail - never "sometimes." Is there any chance this is something I can fix and salavage the drive? Thanks!
