380ED HDD replacement - doesn't want to boot

[ipo]

I'm scratching my head for several days:
In my 380ED (type 2635-6A0) the built in 3GB died. I bought a replacement Hitachi 30GB 4200rpm, installed in the notebook. Made a new partition using FDISK, sized at 2048MB then rebooted. From this moment I cannot boot neither from HDD nor Floppy. Floppy starts booting, then flashes the HDD led and booting stops at "Starting MS-DOS..." with no error message given. I tried Win98 boot disk, same happens. I disabled both config.sys and autoexec.bat on boot disks, doesnt' help.
When I put the new drive to another notebook and finished formatting drive C: and putting system on it, it worked very well in that notebook. But when I put the HDD back to 380ED, it doesn't boot, it stucks - no error given, blank screen.
The BIOS is the latest (FWW49 or something like that), booting order is set properly, I don't know what the hell is going on
Anybody has an idea?

Thanks a lot for pointing me to the right direction!
I had to downsize the disk to 3GB (8GB or 5GB didn't work), and also the SMART had to be disabled. Now the disk boots smoothly, no hangups and actually I'm installing the operating system.

Again thanks a lot for your help!
