Ok. My 120 GB hard drive only has 111 GB

I understand that companies try and round up, but 111 to 120? That doesn't even make sense (Hitachi for what it's worth).

Now, my real question. I am considering returning this MBP and ordering a 200 GB hard drive (which is probably 186, I will bet $5 on it!!). I am already down to 78 gigs on my drive, and it's not even a week old. 78!?! Geez. I can afford the hit financially. Should I just wait and upgrade the drive myself?

It's not a question of rounding up. Your 120GB disk is a 120 billion byte disk.

120,000,000,000 bytes
/1024 = 117,118,500 kbytes
/1024 = 114440.92 mbytes
/1024 = 111.76 gbytes

Disks have been marketed this way since the beginning of disks, it just didn't take as big a chunk out when they were 32MB disks (31250kbyte,30.5mbyte).

It's that pesky extra 24 bytes in a kbyte that kills you. I say we vote them off the island.

(oh, and you're right, the 200G disk will be 186.26gbyte useable)

186? Damn! so by my rough math, I'll have roughly 111 GB left if I upgrade, all things being equal. Sweet. Why do 2.5 disks not have at least 300 yet?

Frustrated and soon out of space,

Yeah Try And Get Full Credit For An Exchange-Upgrade To The 200GB PMR Toshiba

I understand that companies try and round up, but 111 to 120? That doesn't even make sense (Hitachi for what it's worth).
That's par for a 120. The 200 will be about 189 net.
Now, my real question. I am considering returning this MBP and ordering a 200 GB hard drive (which is probably 186, I will bet $5 on it!!). I am already down to 78 gigs on my drive, and it's not even a week old. 78!?! Geez. I can afford the hit financially. Should I just wait and upgrade the drive myself?
No. upgrading the drive yourself may violate your warranty. Very difficult to get to it as well. It's like brain surgery going into a MBP to change HDs - not advised.

The 200 will be about 189 net rather than 186. I win the $5. :p

If you can afford the 10% restocking fee or talk them into waving it, I would try and return it in exchange for a new order for one with the Toshiba 200 PMR. They may wave the 10% fee knowing you want to give them another $200 for the Toshiba MK2035GSS, which BTW I have now decided is the only way to go.

You lucked out on getting the Hitachi. Many here have gotten Fujitsu LMRs. But I certainly agree with you that a 120GB HD is way too small in this day and age of online video podcasts flying down to rapidly consume your local storage medium. 120 is the new 80. 160 is the new 120. And 200 is the new 160. :D

I'm a little disappointed Apple didn't decide to go 100% PMR this refresh. But this is only an issue on the lower capacity HDs anyway.

Please keep us posted on your little upgrade after receiving odyssey. Will be fun learning how easy or hard/costly it will be. I think you have a good chance of being able to get them to wave the restocking fee by calling immediately. How did you buy it anyway? Store or online? Where are you?

A 120gb LMR drive should be exactly as good and as fast as a 120gb PMR drive, so what's the problem?

Hello Guys,

Hello Multimedia, it's seem like you are the big HD expert here so it's good to address my question to you, I guess.

I'm will go for a MBP 17" for the end of the month. I never used mac, I just have a bit o Windows experience so I have no idea about mac software, just think it's worth to change ;)

I thought I should better go for a 100 GB HD as it runs at 7200rpm, because I would like the fastest, portable machine there is and until now I was perfectly living with a 60GB HD on my actual pc. I bought an external HD where I save all my pictures and other stuff so I keep the hd for installing programs.

First question: are 100GB 7200rmb HD Fujistsu or Hitachi? Do you think it would make much difference for a common private user?
Second one: do you think I should go for a bigger drive, and if yes, why?
Third: do 17" mac suffer any problems with fans, screen, hotness or else?
I'm a bit worried about buying such a new machine, you know?

Thanks in anticipation for the help!

Talk to you soon

Really? I have a Maxtor 200GB HD that is net 189.8GB available. Are net capacities different for 3.5" drives than they are for 2.5" drives? :confused:

Getting A 200GB Toshiba PMR Is Probably The Prudent Thing To Do

Who said anything about a problem? I'm simply a perpendicular whore now. No problem. :p I agree with you completely.

No.
Second one: do you think I should go for a bigger drive, and if yes, why?
Yes. Lots of bigger files becoming more prevelant - esp Video Podcasts etc.
Third: do 17" mac suffer any problems with fans, screen, hotness or else?
Not likely. Bigger means cooler. Waiting for reports from first receivers.
I'm a bit worried about buying such a new machine, you know?
I doubt you will really notice a difference between a 100GB 7200rpm (hot battery hog and small) HD and a 200GB 4200rpm (cool battery miser and big) HD. The 17" MBPs are still not in yet. Any day now. I think that if you can afford the $200 hit, having 200GB inside will benefit you long term because there is a lot of multimedia online that loves to fly down the pipe to your local storage for a visit.

We have testimony from a 200GB MBP owner several pages back that it is plenty fast including able to easily capture and edit DV with no drop outs.

Of course, you don't really get all that 111GB. A lot is wasted in indirect blocks, inode tables, and other overhead. And then you oughtn't plan to use more that 80% if you want good performance. Might as well just say that 120GB disk is good for 80GB and be done with it. :D

Ugh, i just saw this post, pulled out my magsafe airline adapter and am seeing the same thing.....

Why on earth didnt I think of that before I bought it, just assumed as it LOOKS like a car charger that it would work...

Just out of curiousity, has anyone actually TRIED to plug it in to a car cigarette lighter to see if it does work?

It won't, the airline electrical source is 24V as I remember it. Your auto is 12V.

Dear Multimedia, please be patient. I'm not American or English (my English is basical) so your answer wasn't that clear for me. Could you please explain all in a bit easier way?
Can I not just move multimedia online stuff I downloaded into my external hd?

Sorry for disturbing again.

Thanks a lot for the help

Got mine today :D It was frozen and moist...but works amazingly. When it's plugged in to the mains is it normal for the right fan to always be on? Because it's been on since i turned it on.

So does that mean the MBP internally can handle 24V, but not 12V? That seems like a major oversight if true. Surely if it can handle 24V, I don't need a massive brick of an invertor just to convert 12V?

This is not really true, filesystem overhead is taken into account when OS X reports available space. Having a lot of very small files will still waste space however.

Also, filling a drive to above 80% capacity has no effect on performance - where are you getting that information from?

actually yes, when you fill up ur hard drive above a certain level, then there is not enough space for mac os x to put the swap files/ temporary files and eventually will cause unstability, kernel panics, crashes etc... :D

I read this recently in a UK Mac magazine (MacUser). They also seem to think that virtual memory size is the same as the swapfile size. It's like they're spreading old wive's tales, they still suggest to anyone writing in that resetting the PRAM is the cure to all problems. They haven't moved on from OS9 days.

I've stopped reading it now as it's always full of errors and plain rubbish advice. They can't even get the Apple model lineup correct - for months they've listed a 1.67GHz MBP as being current, which was never even released!

the inverter converts the 12volts dc output from your car to 110volts ac to feed to you macbook pro power brick that converts it to 24volts i suppose (i have not yet receive my mbpro). it seems the airline adapter is just an adapter, it does not transform any voltage, since the plane output is already 24dc. it cant charge your mbpro battery (not enough power in planes probably) but you can use your laptop as long as you're plugged.
