As we all know, computer data is stored in hard drive, regardless of Windows-based PC or Mac. Thus, if hard drive fails, internal data will suffer as well. This article will expose the 4 common errors indicating the hard drive failures on Mac systems.
Although Mac earns a lot of kudos due to its remarkable stability, errors still can occur to it from time to time. You should never bypass any errors in that some of them may be involved with the Mac hard drive. As you know, all your Mac data is stored in its drive. Therefore, if the drive fails, the data will get damaged or lost as well. When it comes to data loss, it is inevitable to mention that you should make regular backups for your Mac data. For instance, so as to achieve quick and easy PST recovery if PST file gets compromised, you need to back up your PST files on a periodical basis. Of course, it’ll be better that you can get some basic knowledge of the errors, which can help you fix them in time. Hence, here we will unveil and introduce you 4 common errors which sign the failures of Mac hard drives.
1. Kernel Panic
As shown in the following picture, Mac freezes and the entire screen turns grey. Only a power on/off symbol displays in center. Moreover, it says “you need to restart your computer” in several languages. This kind of error is called “Kernel Panic”, same as the blue screen of death on Windows PC. It usually indicates corrupted or incompatible kernel extensions, faulty logic board or CPU, faulty RAM module and even a failed hard drive. In this case, you need to press Power button to shut down Mac. Then restart it. At best, the error is gone. At worst, the error persists, which means that something bad must have happened to your Mac hardware.
2. A folder with question mark
Like the image below, this error doesn’t contain any character but only displays a folder with a question mark in center. It usually turns up after you boot up your Mac. In general, it may indicate two kinds of issues related to the Mac hard drive. One is that Mac cannot find the external hard drive which you select to boot from. The other one is that something wrong occurs to the internal hard drive. Apart from hard drive issues, this error may indicate system file corruption, unreadable boot sector or misconnection between hard drive and motherboard.
3. “Your startup disk is almost full”
As the following error message says, this error is telling you that the Mac startup disk is out of space, which is the best case. To fix this kind of issue, you can simply free up some space on the Mac hard drive. For instance, you can empty the Trash, delete the useless and large files as well as uninstall the unused programs. Nevertheless, in this process, if you find that nothing happens even after you empty Trash and remove large files, it is very likely that the Mac hard drive is failing.
4. “The disk you inserted is not readable by this computer”
This error means that your Mac hard drive is inaccessible and unreadable. This is quite awful in that unquestionably your hard drive must have suffered. As usual, it may suggest that the data on the volume header is corrupted, or the catalog file on Hierarchical File System (HFS) is damaged, or the Mac hard drive contains bad blocks, or the drive heads have been damaged or the drive has encountered other firmware problems.
