Newbie: What is hda1

[sling-shot]

Hi. I am using a Win98se with 40GB harddrive. I want switch over to Linux. So trying the option of running Linux without disturbing anything serious within Windows98 with PuppyLinux For Windows98 [www.murga.org/~puppy]

The bootprocess starts with loading kernel and creating REMdisk or something like that. Then it tries to locate usercram_fs and says uable to locate that file on hda1 though it is there on C:\ partition and root directory.
Why it may be so
What is this hda1/hda2/hdb1 for a windows person?
How to know which partition of mine is hda1?
Etc.
Regards,
-SS.

hda1 is the first partition on your harddrive that's attached to your primary or ide 1 connection.

What is this hda1/hda2/hdb1 for a windows person?

Here's a link that explains it.

That was a fantastic link. Cleared many of my doubts. Now out to check them out ...
By the way i tried googling a lot before to find out what the hell is this hda1. No explanation came my way. There were all sorts of links about how to mount hda1, errors with dha1 etc but none that told me clearly in plain english "what is hda1"
Thank you again...
