Well turns out there are other sizes of laptop hard drive other than the typical 2.5 Yes it call a ZIF drive 1.8 inch, normally use on ipod or other smaller portable music massive storage device. This ZIF drive is similar to a hard drive, it does spin, just that it’s smaller than a laptop hard drive. I came across this because I was fixing one of the small laptop and this laptop use it. I hate the cable connect to it, this cable ribbon is very sensitive and the clip on the ZIF hard drive can break easily, so don’t use too much force on it, take it easy and do it slowly, it’s very small and fragile. The cable ribbon for these ZIF drive looks durable but it’s not, too much wiggle around or bend too much, it will have a disconnect or break somewhere, basically circuit board.
