I am having the same problem

I had a hard drive failure and the computer was repaired under warrenty.
After checking my drives it seems I only have a CD Drive.
This is the info it gives me TSSTCDDVDW TS-L633C ATA device.
Also says Cwindows 32bit system,but My computer is a 64 bit system.
Could this also be a problem

Any help appreciated

Cheers
