Q: External Hard Drive not Recognised by Macbook. Driver issue?

Hi, my hard drive Transcend 2TB is working perfectly on windows.  On mac, i have a Macbook Pro and a Macbook 12 in brand new.  First time i connect it worked fine, but now its random.  Sometimes i can take up to have an hour of rebooting to get my HDD running.  It powers up but not recognised.  Both Macbook pro and Macbook present same behaviour.    Read something about reseting the PRAM, using the keys: COMMAND+OPT+P+R at the same time when rebooting it also works randomly.  Very frustrating.  Looked for the drivers update of the HDD no luck.  Used the DISKUTIL DISK command on the terminal.  It does not list it. Not working.  Also, called Apple support, they mentioned that it was the HDD Format, so suggested MAC OS X Extended format.   So took a day work to backup 2 Terabytes.  Worked the first time connected , now random (1 out of 10 times, maybe less).  Frustrating.

Please, useful advices???

MacBook, OS X El Capitan (10.11.4), Also tried on Macbook proon Macbook pro
