Disk First Aid Query

errors found" but it cannot seem to repair them. Both Norton and TechTools
Pro say the disk is fine. I did have significant disk problems recently
that TechTools Pro fixed. My questions are, What are 'mountcheck errors',
should I worry about it, and what should I do?
Thanks very much in advance.

comma separated numbers that appear after some error messages?
I am also getting the same "MountCheck" error. It is termed a "serious"
error. Unlike Kimron, I have not had anything more than minor errors in
the past.
Additional thanks,

forum for this thread.

Since I still use HFS in stead of HSF+, I am able to use NUM. It tells me
it has found serious erors, but cannot fix them. This is when the
MountCheck error is reported by DFA. After I fix the MountCheck error with
DFA, NUM is able to repair the disk.
When I rerun DFA to see if all is right, the MountCheck errors are there againŠ

I had the same experience - DFA reproted "MountCheck" error and
pretended to fix it (stating afterwards that the HD was OK), but when I
ran DFA again, the same error was reported. At the same time I
experienced that some times my zip-drive showed up on the desktop as six
different icons (non of which could be opend - the computer answerd that
it could not read the disk and asked, if I wanted to format it, but it
could not format it either "because it didn´t exist"). BackUp and
formating my HD _did not_ solve the problem _until_ I coosed "lowlevel
formating" and "erase all data" (optional in the formating tool). After
that DFA reported my HD was OK, and the zipdisks showed up propperly

Sorry. You 'coosed' lowlevel formatting? I think you mean 'chose'?
With what utility did you format your HD? HDT, DriveSetup, Silverlining,
and which version?
You see, I tried all those, all latest versions, only to find that each
utility added another driver to the disk, making even more 'shadow disks'
appear.
Picking another driver with HDT [View Partion Map=>select a driver=>'make
this the driver'] did deminish the number of shadow disks, but the
mountcheck errors kept appearing.
Eventually, I started lowlevel formatting with HDT, and made an emergency
stop with Cmd-Ctrl-On/Off after about 30 sec.
This resulted in a clean, driverless HD after restart.
I then reformatted the disk with HDT: lowlevel, erase all data, after
giving the disk a master password. Until now, this has worked out: no
shadow disks do reappear, no mountcheck errors are reported.
Remains DFA reporting on every second partition of every drive: 'This is
not an HFS disk.' Still, the partition is recognized and mounted without a
problem; NDD 3.5.2 is able to repair the minor errors that occur.
Strangely enough, none of these errors seamed to occur when I started up
from a partition with MacOS 8.0.
Another oddity is that after starting up DFA and quitting the Finder of
MacOS 8.0, no problems are reported at all; each and every partition,
including the troublesome second partitions, is repaired without mentioning
'mountcheck errors' or 'this is not an HFS disk'.
In view of all this complicated 'repairing' I keep a VERY tight backup
scheme; just in caseŠ

Used Apple Hard Disk Tool (that came with the system software).
I have never used any other diskdriver or formating tool than Apples
own.
I have only one partion on the HD (8.1) and no alternativ drivers
The problem with ghost-disk was occoured when I was using a zip-drive
connected to the PB, but as I explained it disappeared compleatly (and
so did the "MountCheck" error-message in DFA) after low level formating
the HD.
