Now is not the time to discover that your backup system (the system you use to keep a copy of what you can't lose) is out of commission.
That second drive can vanish for a short list of reasons. I'll offer one common cure and another common reason why it's gone.
1. Boot a Windows 98se boot disk (I use the one from www.bootdisk.com) and type FDISK /MBR
This method is noted and why in a Microsoft KB article. I will not duplicate said article in this discussion. After this procedure, remove the diskette and reboot into XP and see if the drive reappears.
2. A reason it can vanish is the drive was prepared with something other than FDISK or the Microsoft tools. Without knowing which tool was used, I can't offer any recovery method.
Best of luck,
I'm updating to Win XP from Win 98, I start from clean installation from c:. as the program analyzied the system. it only came up c:, and d: as unidentified on my 2nd hd, e: the 2nd partition on it was missing, I didn't realized this is a problem.
As I follw through the installation process, it ask what kind of filing system I wish to use, I then called my friend who had more computer knowledge than I was, that if I choose NTFS for c:, d: and e: remain in FAT32, would that be a problem for the XP to access those drives, he said that should be okay once the system installed. The fact is once the XP installed, it recognized d: as unformatted, e: is not even there.
What should I do now?
