Time Shaver If a user on a dual-boot system gets an error from Windows XP when trying to save or create a file, but is able to save or create that file with no error when working from Windows NT on the same machine, suspect a quota violation. NT doesn't know about quotas and therefore can't enforce them, which is why the user's operation succeeds from the NT side.
Setting mount points
When you're going through the wizard screens in order to create a new volume, you have the option to select a check box (on the Assign Drive Letter or Path window) that says Mount This Volume At An Empty Folder That Supports Drive Paths. What this means is that you can create a new volume that maps to an existing folder on an NTFS disk. That is, you can add a 4GB hard drive that the user sees as a very large 4GB folder living under an existing drive letter.
If a user is running out of room on drive C, you can add a second physical drive but map it in its entirety to a folder on drive C. This way, the user doesn't have to worry about keeping track of a second drive letter. ('D colon? What's that? Part of D intestine?') Magically, drive C has a new folder with 4GB of free space. You've just discovered the wonder of mount points, a type of 'reparse point' that's new to NTFS Version 5.
Time Shaver If the exam asks you how to add disk capacity when you're already maxed out on drive letters, mount points should figure into the correct answer.
Monitoring hard drives
You can check various details of a local hard drive by using the Disk Management snap-in to the Computer Management console:
1. In the lower-right window frame, right-click the box containing the disk icon and the words 'Disk 0' or 'Disk 1' or whatever number it may be.
Don't right-click any of the partition boxes that appear to the right.
2. Choose Properties, and you see a window like what you see in Figure 7-3.
Figure 7-3: Monitoring drive details.
Again in Disk Management, if you right-click a partition on a basic disk (as opposed to the disk itself) and choose Properties, you see some or all of the following tabs:
* Security (on an NTFS partition)
* Quota (on an NTFS partition)
Right-click a volume on a dynamic disk and you see the same tabs as when you right-click a partition on a basic disk.
Tip You can use the Disk Management snap-in remotely, to manage other PCs, as long as you log on with an account that has administrative privileges both on your PC and on the remote PC, and both computers are within the same domain or at least within trusted domains. You can redirect the management console (COMPMGMT.MSC) by right-clicking the computer icon and choosing Connect To Another Computer. Alternatively, you can create a custom Microsoft Management Console containing the Disk Management snap-in, and point that snap-in to the remote computer when you add it to the console.
Instant Answer Finally, you can monitor disk space use on a user-by-user basis by enabling disk quotas but not enforcing them. That is, on the Quota tab of the disk property sheet, check the Enable Quota Management box, but uncheck the Deny Disk Space to Users Exceeding Quota Limit box. This way, when you click the Quota Entries button, you can view space usage by user name without having any impact on users' ability to create new files. For convenience, you can set warning and limit levels that trigger system event logging and that affect the icons that appear in the Quota Entries list, but these settings don't have any effect on users. (For more information, see the 'Setting quotas' section earlier in this chapter.)
Windows XP Professional supports CD-ROM and DVD optical storage devices. Some (but not all) writeable optical devices, such as CD-RW drives, can also work with Windows XP Professional depending on the availability of Windows XP device drivers.
Windows XP either works with a given make and model CD-ROM drive, or it doesn't. The famous Microsoft Hardware Compatibility List (HCL) is the guide here.
Instant Answer If you need to install Windows XP Professional and your PC's CD-ROM drive isn't on the HCL and doesn't work, Microsoft recommends that you choose an alternative method of installation (such as using a network distribution server) or install a different model CD-ROM drive.
Instant Answer If the exam mentions El Torito, it's not referring to a brand of tortilla chip. It's referring to a specification that lets a computer boot from the CD-ROM drive. You may have to set the option in the PC's BIOS setup. Booting from the Windows XP Professional CD is handy for installation and system recovery purposes (beats the heck out of using diskettes to start the computer).
One advance since Windows 2000 is the ability to burn a writeable CD (CD-R or CD-RW) by just dragging and dropping files onto the CD drive's icon in the user interface, or by selecting the files in My Computer or Explorer and copying in the usual way (for example, with the context menu's Copy command). However, you must format the CD before trying to copy to it.
