How to Fix MacBook Pro doesn’t recognizes external hard drive
There are times when your MacBook Pro fails to recognize an external hard drive, and leaves you startled. And as an English saying goes – “When it rains, it pours”, the issue gives rise to several questions in your brain, like – what to do when MacBook Pro doesn’t recognizes external hard drive, or what to do if MacBook Pro does not recognizes external hard drive, for that matter.
The first thing you should after your system fails to recognize the external hard drive is to restart your computer and see if it did the trick. If it did not, then you are advised to run a scan using MacKeeper to neutralize any potential malware, or viruses. However, if you do not have MacKeeper installed on your computer, then scan using any anti-virus you have installed on your computer, and see if that helps. Add to that, if you do not have any anti-virus, or a mighty software package like MacKeeper, then you are advised to download MacKeeper because by now your MacBook Pro must have become a hornet’s nest in absence of any anti-virus package.
At this point, if your system starts freezing after the restart, then remember to boot the system in safe mode. For that, you will need to shut down your Mac if you have not yet, and then press the power button to turn on your Mac, and just after you have pressed the power button, press “SHIFT button” to boot your computer in safe mode, perform few random operations in there, and eventually turn your Mac off to start it normally.
In addition to that, the issue in question, that says – MacBook Pro no longer recognizing external hard drive, can be fixed manually too, but the only problem with manual solutions is that they need utmost care and attention while being executed; otherwise the execution may result in fatal errors. So, you can try connecting the same hard drive to some other Mac or system and see if that system can access the data from the hard drive in question, if yes, then, your hard drive is okay, and most probably the disturbed part of your Mac is the flex cable that connects the hard drive to the logic board.
So, in order to troubleshoot the issue try replacing the flex cable, and either you could consult Apple service center, or you could replace the cable yourself, but use a nylon probe tool to disconnect the battery from the logic board first, and then remove the cable connector from the logic board avoiding any harm to the logic board. After that, fix everything in its place, and start your computer again, and try working with the hard drive. Hopefully, the issue will no longer exist, and so the mind-boggling problems will, for instance – what to do when MacBook Pro doesn’t recognizes external hard drive, what to do if MacBook Pro does not recognizes external hard drive, etc.
