My External Hard Drive have not got Recognized on my Mac Computer

Recently I bought a new external drive because my old Macbook Pro Hard drive got failed and I wanted to regain all the data back on the new drive but when I plugged it in, my external hard drive have not got recognized on my Mac. Afterwards when I tried backing up data automatically, it didn’t work and kept on crashing. So, I transferred most of my data files manually to the external HDD. But when I connected it with my Macbook Pro it kept on notifying me that, it is not recognized. What it really did, it made a humming noise and the lights started blinking off and on but it didn’t show up in my system.

Plug in the external hard drive and ignore the pop up message.
Go to Disk Utility, which should be present in your applications tray area.
Now you will see two devices, one is your main and another is your external HDD. Identify them with their names and choose the external one.
Now go to the tab of partition located at top right and click on one or many partitions, and make sure the format for the external hard drive is Mac Journaled Extended.
Click Apply. It will clean out the whole drive for you to make partitions, as per your needs.
Supposing, if the size of your external hard drive is double the size of the internal one. Make only two partitions, one for machine and one for carbon copy cloner, for the purpose to create a bootable back up of your current setup. So, in case, if your hard drive gets failed ever, you would be able to use your Macbook Pro from the external drive.

I hope your problem has been resolved. But, if it persists you can call anytime to our support center at 1.800.347.5377 for full assistance.

I wanted to extend my ultimate gratitude and thanks to you and your team. Not only did your company recover the data quickly and at half the price of other companies, everything was recovered and our office is back on track after the NAS failure. I really appreciate a company doing its business so well as Disk Doctors did; and will definitely sing your praises for all to hear. Excellent customer service all around. Thank you again!

What do you do when a power surge destroys your hard drive and you loose hundreds of hours of work, irreplaceable images, and your ability to complete jobs for clients with looming deadlines? My first instinct was to cry, then scream. My IT manager tried and failed to recover my data and recommended that I try a disaster recovery service. We went on line and called several companies, and when we reached the Disk Doctors, we knew we had found a company that could help us. I delivered my toasted hard drive to their Vancouver location late in the afternoon and by 6:30 am the following morning a representative had emailed me with a reassuring message and time line for the work. The following Friday I received one of the happiest calls of my life. My data had been completely recovered. I cried and screamed again, this time with joy! Over the last two days I have been thrilled, delighted, relieved, overjoyed and reassured by the fact that ALL MY DATA is once again accessible. Disk Doctors are now on my top-persons list and I am telling all of my colleagues about their services!!!

Thank you!

My hard drive crashed leaving me without my critical financial information and research that is crucial to my business. After checking various vendors on the Internet, I chose Disk Doctor Labs because of their level of service, and they far exceeded my expectations. Aziz Mirza, the manager of Disk Doctor Labs in Norcross, GA, personally took charge of my account, quickly fixed the problems and returned my restored files within a week on a hard drive that I could return for an account credit. Throughout the process, Disk Doctor Labs kept me informed, responded quickly to my calls and delivered my lost files quickly, efficiently and at an extremely fair price. I recommend them unequivocally.

Thank you!
