DVD drive not detected after crash

Hi Guys

I use Windows XP.
It started when my harddisk lamp keep on lighting like it's reading then suddenly my computer crashed.
It cannot load windows and BIOS said can't detect my harddisk so I just turn off my computer and unplug then plugged back the cables of my harddisk.
After restart BIOS detect my harddisk back and windows do chkdsk before starting & I notice no bad sector so I think it's good.

The problem is now my liteon ihas 124 dvd drive not show up even in BIOS. I already tried unplug & plug the cables with no success. The power light is on though.
Then I tried with another dvd drive LG and unplug Liteon.
Bios detected LG but the names not correct. I check in device manager there the name is correct.
I then restart my computer & this time in BIOS the name is also correct so no problem with LG I guess.

Now I plug both LG and LITEON and both detected in BIOS but named with funny characters and windows can never finish loading. So I reset and this time both drive not detected in BIOS.
Before crash I mount LG & Liteon together and both work with no problem. I need my liteon to work as it's newer & my LG already weak.
My harddisk and both dvd drives are SATA

Please help.


Thank you
