the title pretty much says it all.
my 3tb usb 3.0 external drive ejects from my macbook air upon detection and hangs up the OS
i thought i lost my data numerous times (15yrs worth :eek:) but no.
my tests prove its the newer versions of the OS's, i dont know what they are doing but it aint working!
only OS it works perfectly on is 10.7.4, anything above no.
anybody else experiencing this? or know of a solution? please

I currently have a WD MyBook Studio 3TB. It works fine in 10.6.8, worked fine in 10.7.4 and works flawlessly in 10.8 -.2. Never downloaded 10.7.5 as I was all ready on ML then. It worked fine formatted as OS Extended Journaled. Currently formatted as ExFat
Lets see if someone else has the problem.
