using fsck -y

[yanges]

apple's G5 support site says to use the install disk and use disk utility when Tiger is the installed OS rather than booting the computer into terminal mode and using fsck -y to check and repair hard drive?

why is it not Ok to do it directly from the boot method?

Thanks!

You can still use fsck -y in single-user mode, but there are even files that fsck -y can't modify. Single-user mode is a stripped-down boot mode, and there are still files in use that cannot be modified.

By booting from the OS X install CD, you guarantee that all files on the hard drive will not be in use, and it can perform a more "thorough" repair.

Thanks for the info!

occasionally i see it listed as sbin/fsck -y or something to that effect...

is just using fsck -y sufficient?

"sbin/fsck -y" is just executing the fsck program in the sbin folder.

"fsck -y" will use whatever fsck program falls under the PATH definition for the shell. I think the default is sbin, so "sbin/fsck -y" is probably redundant.
