I was highly amused in computer repair class today. We have 8 computers, which we've learned to assemble, install Vista on, and some other things. Today our assignment included the task of setting a disk quota. The assignment specified 1MB as the limit, so that it'd be easy to exceed it to see what happens.
Four of the computers ended up unbootable or unusable.
Apparently Vista decided to apply that quota to all
users, including administrators. And if you're way over your quota limit, it's impossible to log in. And that limit includes the user profiles and other junk that's already there that well exceeds 1MB. Oops.
Mine and another had a bonus fail. The video randomly cut out, and refused to come back. Tapping the keyboard and moving the mouse, occasionally the display would come back for half a second before disappearing again. So we hit the power button, which by default triggers a normal shutdown without prompting.
Turns out Vista had decided to start installing some updates. So during shutdown, the video comes back on, and we see "Windows is installing updates" followed immediately by "Windows is shutting down". Vista happily interrupts the update process to shut down.
...Without letting it clean up. Which means the registry is left in a mess, leading to a BSOD on boot, even in safe mode. Yay!
It gets better still: Even the recovery tools on the install CD impose the 1MB quota limit. So while a backup copy of the registry exists, the disk is considered full even after removing files, so I can't copy those backups to where they need to be. I could move them, but they're the only backup, so the system might end up completely
hosed, if it's not already. So next week I'm going to have to use a Linux CD to bypass the quota and copy them.
(And then I'll explain why they really should be teaching how to use Linux, even if it is to fix Windows. >.>)
Even System Restore claims the disk is full now. I suspected the disk may have just died, but chkdsk reported no problems.
