I noticed this question was asked quite a few times already in varying forms; however, I saw nothing that really answers my question...
So here goes; I have an older Dell laptop that needs a new hard drive (the current one has screamed it's last :) ). My hope is to replace it with a 128 GB PATA/IDE SSD (I have found these on Amazon); what I have been unable to find is how to figure out whether this drive will work with my computer. I tried checking owner's manuals; but they had no information whatever what to replace the drive with. Is it simply a matter of counting the pins and measuring the old one and comparing the measurements? Or is it more complex?
