Installing a Hard Drive in a PowerBook 12 “


I have already told you the misadventures of my hard drive Powerbook of 12 “in this entry. In it I told you that I had bought a new hard disk to replace the previous one, a Hitachi Travelstar 80 Gb, memory of 8Mb cache and 7200 RPM. Apparently, it is not recommended to install a 7200 RPM hard drive because of the heat it gives off, and also because the consumption is higher than a 5400 hard drive. This reduces the use time when we power our laptop with the drums. The advantage of this disk is that the performance is much better than with the original hard disk, as we will see later.

Changing the hard drive of a Powerbook It is, apart from being heavy, a bit confusing due to the variety of screws used and we do not recommend it. If despite our advice, you want to wrap the blanket around your head and do it yourself, we recommend that you continue reading. We are going to give you some very valuable tips to make the operation as bearable as possible.

Let’s get down to business. For surgery to be successful, we need a few things. First, have time. The process can take about an hour and a half. Obviously you have to take it easy, no rush or stress. Second, have a well-lit and sufficiently large work table. Third, a good set of screwdrivers is essential. No “all to 100” screwdriver set. Why? Well, I found out that Superman does overtime tightening the screws on his laptops. Mac. If the screwdrivers are not good, we will eat the heads of the screws and have enough problems. Fourth, have a tablecloth or mat to put under the laptop while we handle it. This way we will avoid scratching it or greater evils. Fifth, a roll of cellophane.

At this point, we download as a pdf and send the iFixit guide on how to change a hard drive to the printer. It is essential to print it on paper as we will see below. While it is printing, we go to the kitchen and make a lime to calm our nerves.

Once printed, we read it carefully. On the first page of the same, it tells us that we need a # 0 philips screwdriver, a flat-tipped one, a T6 torx screwdriver or key and a paper clip. It also tells us the parts that must be removed in order to change the hard drive. The steps to follow and the screws to remove are clearly listed throughout the next eight pages. My advice is that you follow the steps and that you glue the screws in each of the steps in the guide and in order of removal. Thus, when we reassemble everything with the new hard drive, the only thing is to follow our steps in reverse order, take off the screws and place them. In this way we save time, headaches and minimize the possibility of making mistakes.

Forget about the three pages of screws that appear in the PDF. It would only bring you more complications to stick the screws on these three pages as recommended in the guide and having to go looking at each step which are the screws to mount.

Aside from cursing in Hebrew a few times over the topic of too tight screws (repeat, you have to be patient and GOOD screwdrivers) the process is simple. After mounting everything again, we insert the system disk and reinstall the operating system. The laptop heats up a bit more on the hard drive side, but its performance is much better. Application load really flies. I have not been able to take measurements of the previous hard disk to compare, among other things because I do not trust the veracity of the same being the disk “half damaged”. What I have done is run some tests with the new hard drive using the Xbench utility, and then compare those results with those on their website.

You can see the results here:

If we compare them to the Xbench page results for the original 40GB 4200 RPM hard drive, we see that the performance is significantly better. In fact, the score obtained is more than double (34.08 vs. 15.4):

We hope we have given you a few tips with this post.
