HD read in windows but not in mac

[jonzg]

Hello, I have a WD My Book Essencial 2 TB 3.0 HD.  It is formatted mac with a GUID table and formatted HFS, it had worked perfectly for 3 years on my imac.  Now for the last couple of months, OSX 10.10 mounts de drive but then after 5 seconds it gets disconected.  I have reformated and nothing.  The strange thing is that if I use my windows 8.1 partition using bootcamp on the same imac, the drive works perfectly, it even reads the HFS drive because of bootcamp drivers.

Any ideas why it won´t work in OSX 10.10 but with windows it does??

Thanks

Jonathan
