Mac recovery software to deal with nvram corruption
Mac recovery software to deal with nvram corruption
Among many other wonderful applications from Apple, Logic Studio is one. Logic Studio is a complete application to record, write, edit, perform and mix music. With various effect plug-ins, sampler instruments, audio loops etc., this utility allows you to handle your project single handedly at any any stage. But, with more features, there involves more complexity. You were working with Logic Studio and the application suddenly crashed following any error with your Mac OS X. On rebooting, the system just hanged at the start-up screen with a flashing question mark symbol and all your data in the drive remains inaccessible. In such a situation, any good Mac data recovery utility can help you recover your seemingly lost data back.
While rebooting the Mac system from the installation disc and trying 'First Aid' from the Disk Utility, you may get some error messages. After the error messages, the system remains inaccessible as it was. The error messages, which you received can be as below:
'The volume 'Macintosh HD' needs to be repaired
Error:filesystem verify or repair failed'
'Verify and repair volume 'Macintosh HD'
the disk 'Macintosh HD' could not be unmounted'
Causes:
There can be a number of possible reasons behind such an unexpected problem, including a bad RAM, bad sectors in the hard disk, corruption of nvram or even corruption in the journal entries in the file system etc.
Resolution:
Start the process by checking various connections of the Mac system.
If everything is OK and you are having the same problem, reselect the startup volume after resetting the nvram.
If the above measure also fails and Disk Utility could not make any impact, then reinstall the operating system with 'Archive & Install' option.
If the 'Archive & Install' option fails, try the 'Erase & Install' option.
The Erase & Install option will completely erase the data from the Mac hard drive and make fresh installation of the operating system. With this process, all your data from the drive will be lost and you need to look into your backup server for some recently taken valid backup. If you do have a recent backup, you can restore the data from it, or else you have the single choice to run any mac recovery software and recover the data back.
