OWC Mercury Elite AL Pro Not Showing Up Suddenly

Hey everyone,

Today my external hard drive is suddenly not showing up in my computer or on my one file manager program. It is really weird cause the computer reads it and it comes up in disk management and in my device and everything says it is working fine.

I check for updates and everything with no luck. Rebooted it and tried all the simple fixes like that. I dual boot this computer and the external drive pops up on OS X Lion fine and lets me access it and everything, so it doesn't have to do with the hard drive itself.

It has been working fine for months and I really don't think I changed anything in the last day or two with the computer for it to suddenly not be working. Very strange problem. Windows basically says its working fine except it just won't show up in My Computer. I tried connecting with both a Firewire cord as well as USB and neither work. I spent hours checking all over the internet and still no luck.

Any advice? Please help!!

Thanks,
Dom

Mine just died not to long ago. That Oxford chip set doesn't last very long on these things. Been looking for something else that doesnt use that chip set.

You have the same brand? Thing is, it works completely fine when I boot into the Mac side.

My roommate has the exact same model as mine and he just tried to plug his into my computer and the exact same problem is occurring. I am pretty sure the external hard drive itself is fine and it something with Windows 7. Any advice?

Got it. Turns out after messing with its settings, it was somehow marked as unlabeled and I simply assigned a new drive letter to it and it immediately popped up working! Solved!

Hi justananimal32. Specifically what settings did you have to change? I am experiencing the same problem!

All I simply did was go into control panel -> system and security -> administrative tools -> computer management. Then hit disk management on the left hand side. Or hit start then run and enter diskmgmt.msc to get to disk management faster.

Once in disk management go down and right click on the drive you are having an issue with (if there are no names distinguish it by the size) then hit change/assign drive letter or paths and add a new drive letter to it. That's all!

ah, those options appear greyed out to me, is you mercury elite formatted ad NTFS? I think mine is formatted as SATA, and thats why its greyed out?

Sata isn't a drive format though, but yes mine is formatted as NTFS. All of those hard drives are by default formatted as NTFS so I think yours should be too. Upload a screen shot of it if you can so I can try and help ya.
