Hi
I have never experienced this before, but suddenly my Slave 1 (MacPro 2009) boots with the information that one of the drives isn't recognized. Disk Tool doesn't report the drive, so what can I do?

Is it a spinning drive or ssd? If the latter I've no idea.

If the former then my own response would be to extract the drive from the machine and purchase a cheap usb drive dock like this
http://www.maplin.co.uk/p/25-inch-a...hq?cmpid=ppc&gclid=CKO-toOa3dICFY0V0wod0bUNFQ

Place it in the dock and fire it up. Listen to see if you can hear the disks spinning up ok, and if you can hear any unusual noises like clicks. If you can hear anything unhealthy switch it back off straight away and consider sending the drive off to a specialist recovery firm (get local recommendations there are plainly some cowboys around) who may be able to save some of the data. It can be expensive for little/no data return.

If the drive sounds ok then the chances are that it will have mounted via the usb device and you can access the data. If it's spinning up ok but still not accessing ok then that is good info to have when trying to recover the drive - essentially that the disk platters themselves are probably undamaged.

I'm really not an expert in this, so you may find better advice. Good luck!

Hi
It's an internal drive 1T. My problem is that I can't remember what was on that particular drive. I have taken it out and reinserted - kind of hoping it could do the job - but no it doesn't work.

So, you need to determine why it doesn't work. Mechanical or electronic failure? If mechanical, is the nature of the fault damaging to the platters? ...or is it of a less problematic mechanical nature (stuck head). If the drive is making no sound at all then it's likely to be a power issue. If the drive works perfectly in an external usb unit then the problem is most likely in your mac. etc etc.

getting the drive powered up and connected back to you machine externally - away from other drives - is your 1st priority. You will be able to determine very little with it inside the box.

best,
Chris
