Safe Boot & fsck -y

[pendragon]

Elsewhere on the web, I have seen comments asserting that when one boots in to Safe Boot Mode, the system performs a check/routine that is the same as that done when one performs an fsck –y.

But, is this an identical routine are only a similar routine?

And if they are different, how so?

Just curious.

We seem to read the same forums....I started seeing the references to the "safe mode" or "safe boot" very recently & am also curious.

I haven't had the time yet to really delve into it.

When I get time & learn anything I'll post here.

To me it looks like an OS X version of Extensions Disabled.

It may run fsck -y during the process.

Thanks for the article #....yes, that's exactly what it sounds like.

I do run fsck -y on a more or less regular basis, maybe once a month.

While I pretty much knew what Safe Boot did and why it is used, I was trying to determine if the Safe Boot start up process specifically ran the fsck -y routine, or just something similar to it.

I suppose for all practical purposes it matters not. Though still I am curious.

 It's the same thing.

Incidentally, if your hard disk is formatted using MacOS Extended (HFS+) rather than UFS, when you run fsck it uses the Disk First Aid libraries. In other words, running Disk First Aid is the same thing as doing fsck -y.

Disk First Aid and fsck are only different if your hard disk is formatted for UFS.

Thanks all for hanging in there with me. I just wanted to ensure that I had an understanding of the situation so that I do not perpetuate bad info to others. Um, er, not that I have ever done that of course...
