Any disk based Operating System requires a certain amount of maintenance both to ensure that it operates efficiently and to prevent mishaps from occurring. Even though, your iMac’s all in one design reduces the number of cables your computer needs, it is still possible that your hard drive may get corrupted due to some other logical reasons. When you turn on your iMac to perform daily work, it suddenly freezes!!! Even after waiting for a long period of time, you are not able to access the data. In such case, it needs hard reboot. This temporary glitch is mainly associated with the abrupt system shut down.

Abrupt system shutdown may cause file system corruption making all your data inaccessible. To keep track of where each file is stored, your Mac OS maintains a directory which tells your iMac the names of every file and the exact physical location where each file begins. Files are divided into blocks, and typically the end of each block contains a pointer to the next block of that file. The division is transparent to you and when you open the file, you can see all the blocks altogether. Therefore, when directory structure gets corrupted, the allocation information of each and every file is destroyed. Sometimes it may lead to hard drive failure and you will have to face huge data loss. In such situstions, you need recovery software to retrieve data from failed hard drive. Mac hard drive recovery software helps you recover files efficiently Mac failed Mac drives.

Some harmful viruses may add incorrect information in the file system by infecting the boot sector of your iMac computer. The incorrect information results in freeze, power outage or some other forced reboot. As a program makes changes to a file in memory, the changes normally are saved frequently but not instantly. When your Mac does not shut down properly, the OS checks the directory structure of the boot volume when it starts up. If the directory structure is really corrupted due to viruses or due to any other reasons, it’s rare but possible for MAC OS X to stop its startup process. In such case, it drops you into single user mode by displaying command line interface instead of a typical login finder.
