Data loss due to flashing question mark in Mac
The flashing question mark on your Mac machine usually occurs when Mac fails to recognize the system software, which is essential for it to startup. There might be other reasons like issues with the mouse and keyboard, which might lead to this error. After this error occurs, the system might either start normally after a small delay, or it might not startup at all. In some cases, the problem can be fixed, by starting up with a system software CD or DVD.
During the startup process, there are chances of the data present on the hard drive getting deleted, and hence the user has to make sure, that proper backup is taken before performing the given task. In the absence of a suitable backup, there are high chances of data getting lost or deleted, hence making the need for a undelete Mac software essential.
However, making use of a Mac OS X recovery software, without proper guidance could prove to be costly for you. Mac Recovery software is the most trusted and highly ranked Mac recovery software, which is capable of recovering all your Mac data from both HFS+ and HFSX volumes. The software not only salvages lost data, but also locates missing volumes on your Mac.
