I cant see a HDD in My Computer

[chinny]

I cant see a HDD I put in my computer when I use My Computer or Windows Explorer. My Bios sees it, as does my device manager. The device manager doesnt have an allocated drive letter for the newer drive but it has one for the floppy, other 2 HDD's and my DVD/CD R combo.
I run Windows 98 SE on a 700mH AMD with 256Mb of RAM.
It's all plugged in properly and the IDE cord seems to work because BIOS and DM can see the HDD.
How can I set the new HDD so I can use it?

try disabling it in the device manager and rebooting.

Windows 98 has difficulty is seeing more than 2 physical drives.  Use this utility:  http://www.v72735.f2s.com/LetAssig/

I tried both of those but niether works.
Letter assigner doesnt even see the other HDD either.

To summarize, you have 3 hard drives and 1 DVD/CDRW.

You should have 2 Masters and 2 Slaves, one each on Primary and Secondary.  

Only thing I can thing of, is your new drive larger than 64GB or 137GB?  What size is it?

The 3 hard drives are 3G, 6G and 8G plus a DVDROM/CDR.
The 3 is the primary master with the 8 as its slave with the CDR as secondary master and the 6 being its slave.

Have you tried booting from a boot disk and running fdisk to check if there is actually a partition on the drive and that its formated?
