Miniguide to fixing Volume-Filesystem errors Apr 29, '11 07:30:00AM • Contributed by: santa97298 There are many drive/filesystem errors that can occur on a Mac.
The Volume Macintosh Hd Could Not Be Verified Completely
Here are some common symptoms that are indicative of some of them:
The Volume Macintosh Hd Could Not Be Repaired
Not able to boot the system: You tried to boot. Apple logo appeared, and wheel spun for about mac single user mode commands 15-20 seconds, then machine turned off. This repeated every time you tried to boot the system. (REASON: The system does not find your HD and thus the OS to boot). https://discussions.apple.com/thread/2736687?tstart=0 Everything seems to work fine till your system hangs briefly and in an unpredictable way. You wait for a while, and the system magically comes back to normal. But after another while, the same thing re-occurs! (This cycle repeats in the current session). You can do these simple things to check for other possible causes: Run Activity Monitor to http://hints.macworld.com/article.php?story=20110216112523818 see that this is NOT due to temporarily high CPU and/or Memory usage. Check the system log using Console.app or running tail -f /var/log/system.log in Terminal. If your system is having some I/O error then it is sure that there is an HD failure issue. I don't claim to be an expert on this subject matter, just an (over)enthusiast Mac user. This guide is purely based on my personal experience and is bound to contain errors. So, USE IT AT YOUR OWN RISK! [crarko adds: Consider this hint to also serve as a reminder to check your backups...]Possible problems: Your HD Volume/FileSystem is corrupted Verification: Use Disk Utility and run "verify" to check it. 2. Your HD is dying. Verification: Use Disk Utility and see the SMART status of your HD, although this isn't always reliable. Before making any repair of the disk, make sure that you have the latest backups. Repair might let loose the volume/filesystem info all together and then there will be no other choice than to recover the data by some data rescue
