SYMPTOMS
When you try to upgrade to Microsoft Windows XP, or when you try to install a hard disk on your Windows XP computer, the hard disk may not appear in Windows Explorer or in My Computer, even if the hard disk does appear in Device Manager and in Disk Management console. You cannot use Disk Management console to assign a letter to the hard disk.



CAUSE
This problem may occur if you have used the Roxio GoBack program on the hard disk. The problem occurs because Roxio GoBack modifies the master boot record (MBR) and changes the partition type on the hard disk. This can cause the drive to be inaccessible in Windows XP, even when the hard disk appears in Device Manager and in Disk Management console.



RESOLUTION
To resolve this problem, contact Symantec for the latest updates to GoBack. For information about how to contact Symantec, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base:

WORKAROUND
You may work around this problem by using the following steps:

WARNING: If you are not sure that you can safely follow these steps, contact your hardware documentation or contact the manufacturer of the hard disk or the computer before you continue.  Configure the hard disk as the primary master, and then restart the computer. Disable Roxio GoBack. To do so, follow these steps:  Press SPACEBAR to view the GoBack boot menu. Press D to disable GoBack, press Y to confirm, and then press ENTER two times.  Shut down the computer and then return the hard disk to its original configuration.</li></ol>
