I have a Western Digital My Studio external HD that doesn't seem to be working too well. I'm not sure what the deal is. Sometime it won't mount on my desktop while its connected. I tried turning it off/on several times but you can hear the motor. It seems to be spinning up and then down and then up. However I got it to mount a few times on my desktop and was able to read/write to it without any problems. I decided to open up and remove the actual bare HDD and insert it directly into my PowerMac G5 tower. It immediately detected it upon bootup and mounted fine on my desktop. But today upon booting up into Mac OS X the drive won't mount at all after several attempts of restarting. The odd problem is that the drive is perfectly listed under my Disk Utility app. Everything looks okay from what I can tell as far as the SMART STATUS and etc. Can someone please tell me what is wrong? If Disk Utility manages to detect the drive does this mean its safe to assume that I can fix this problem and have the drive actually mount on my desktop so that I can access the files on it? I'd sure to lose 1TB of information. Any help is appreciated. Thanks!
