Holding down the power button to shut down is not recommended
It should only be done if all other methods fail
Once you do that you should verify that the forced shutdown has not damaged the disks
Do you have any backups?
I back up the data, not the OS disk.
I know hard shut downs are not recommended. But when the power failed it knocked out our KVM switch and I didn't take the time to retrieve a smaller display and plug it into the back of the server. I realize this was poor practice, but I was trying to restore our complete system (6 servers) so we could publish a newspaper.
I'm sure there are other handslaps you can apply.
