On my laptop, (toshiba sattelite C55t-C5300) for whatever reason, my old hard drive failed (model number: MQ01ABD100), and I ordered a new hard drive (model number: MQ04ABF100), and i'm unsure if the drive is compatible with my laptop, and I'm unsure how to insert the drive without covering the "breathing hole".Can anyone familliar with these models assist me? If the hard drive I ordered is compatible, how do I insert it? If it isnt, what should I look for when trying to replace the dead one?
