i have a webplayer and i have installed windows me on it with a 6gig drive and i also have win98 on the doc, thanks to the wonderful instructions on this board and at larwe.com. imho, you should be able to do it easily. lets sort of do a checklist to pinpoint the problem.
As already mentioned you might want to check out the following:
1. make sure the hard disk is master (i am not sure if cable select works on the webplayer) assuming it is the only hard disk on the system. otherwise have the other one as slave or better yet disconnect it till you figure out that this hard disk works.
2. i _think_ (not sure but doesn't hurt to check) i have seen some ide cables which go both ways into the harddisk. normally ide hard disk cables will go only 1 way so that pin 1 on the hard disk matches pin 1 on the motherboard. if your cable goes both ways, make sure that pin1 from the motherboard matches all the way to the pin 1 on the hard disk. if u r using a desktop to notebook ide adaptor, it needs to match there as well.
3. check if it is detected by the bios correctly
4. you should be able to check both your hard disks for proper functioning with the hard disk manufacturers software, like western digital has some software etc. that should tell you if there is anything wrong with the disk. they also have some disk wipe utility etc.
5. if all the disk does is spin and bios doesn't detect it _may_ be it is a bad disk.
ok, once bios identifies your hard disk:
1. on a computer which has cdrom as well as floppy, boot with a dos bootable floppy (u can get one from bootdisk.com), run fdisk, create a 2 gig primary dos partition (if you are comfortable use ranish partition manager), mark it active, exit out of fdisk, do "format c: /u /c /s" (i think /s is to transfer the system i am not sure, just check it out).
2. see if dos boots.
3. copy the entire win98 cd to the hard disk.
4. connect harddisk to webplayer, boot, and install win98.
lets us know where you are having trouble. all the best.
