hello,
this morning when i turned on my pc it says "reboot and select proper boot device" last night its still functioning. I looked at the BIOS setup but i could not find my Samsung HDD in SATA list, I only saw my SATA CD/DVD ROM drive. I tried using another samsung HDD about 160GB then it appears in my BIOS setup as my bootable device.Could someone tell me if my previous hdd is already DEAD? or it's just corrupted or something?
I just need know if there is still hope that my previous HDD would ever run again.

thanks for your help.
