Macbook or Pro losing files? Here is something to consider
Laptops are becoming more visible, useful and widely purchased these days. It seems like laptops are being used as the main Mac or as a secondary Mac all the time.
People instinctively know that laptops are more susceptible to dangers than a desk locked Mac. Laptops get moved, lost, stolen and thrown around more freely than ever before. Of course, a laptop is subject to more damage than its desktop counterpart, dropping, bouncing in backpacks and general use puts more strain on just about everything inside it like hinges, latches, dents and so on.
So what causes Mac laptops to lose their brains more often? Flashing question marks, missing startup disks, slow starts and other anomalies. Its not the moving, dropping, banging or using but something much more insidious. Here is the cause of a large percentage of drive failure or lost data on your laptop, be it missing files, songs or a failure to startup.
Magnets and Radios
When questioned, people usually remember after the fact that the computer was either set on or had something set on it. If you set your computer on something that generates powerful magnetic or radio signals there is an increased likelihood these can cause a bit, byte or data write on your drive to get scrambled thus causing the file that data belongs to to become unreadable.
Ah ha, thats why my iTunes library is missing songs. Or worse yet the effected data is part of the boot sequence which causes it to hang during the startup process. Yes its true, if you set your iPhone, iPad or some other gadget down on top of your closed Mac, whether the Mac is in sleep mode or turned off completely, anything causing your phone to get or send data, ring, get email, look for bluetooth or a host of other tasks causes the device to generate signals that can cause data loss on the disk drive a mere half inch away.
And many people unwittingly lay their Macs down on powerful electromagnetic generators like microwaves and stereos or the large speakers while they’re cranking out music. These generators produce waves that lose their force the farther away you get from them and usually have some shielding that protects nearby devices. But it doesn’t take much to scramble just a small segment of your drive’s data and can cause a lot of grief in the process.
So be careful about where you set your laptop these days, Strong magnets are everywhere. From the trunk of your car to the dashboard you’ll find some sort of danger zone that can cause damage to your drive. And that smooth flat surface of your laptop is so inviting to set your phone on. Don’t do it. The new rule is think before you set it down.
