Couldn't unmount disk (-1000) leopard 10.5.4

Hi Guys,

I am running leaopard 10.5.4 and I have just partitioned my HDD in two equal partition of 46.58 GB with guid partition table on both.
Before partitioning to verify my disk and repair if needed to be I used to run fsck -fy. Now when I do so, I get the error message saying that "could not unmount disk (-1000)". I tried to unmount the partition /dev/disk0s2 but that is the partition system 🙂
is that error message link to my new partitioning?
is there any way I could get around that pb? ( i have no other way to run fsck -fy to verify and repair my disk. I cannot install any third party software on my computer.)
I checked the SMART status and it is ok. I have also repaired the permissions on /dev/disk0s2.

Thank you all for your help.

Is this HDD the internal disk on the MacBook?
Where is your Operating System disk located?
Does this disk have a file system on it to check?

Yes it is the internal HDD of the MBP

Where is your Operating System disk located?
I assume that you would want me to use the disk utility in the install disk 1 ?
I cannot use it due to firmware restriction

Most of all, I get the error message as well when I run "diskutil repairVolume / or diskutil repairVolume /dev/disk0s2"

Thanks

You have partitioned the volume. You will next need to format it. Then run Disk Utility (which does the same as fsck) on it, from your Operating System.

As to the firmware restriction, there may be some young buck wanting to show off their skills, but I don't favour circumventing security. I suggest you take it into a Apple repair centre and ask them to remove the firmware restriction. But this is not stopping you from doing the above.
