I use a Toshiba Satellite Laptop and the model number is P15-S409. As of late my computer is running a bit slow. I have gone through with all the basic and essential maintainance like disk cleanup, defrag, disk check for errors, run spyware and adware program, anti-virus, etc. At this point, since I have not really been able to get much improvement, I am wanting to reformat my hard drive and just do a clean start. Here’s where the problem is. The CD/DVD drive is worthless as it no longer works. I have searched for hours on various forums looking for the right answer to get it to work and all to no avail. So, 1) Does anyone know of any tricks to get this drive to work for me? 2) If not, any idea where I can purchase another CD/DVD drive that’s reasonably affordable and will be compatible with my laptop? 3) Can you tell me what brand and model number to buy? 4) Please offer any other advise that could possibly pertain to this matter. I appreciate any input offered and thank you for taking the time to read through this.
