Hi all,

I've searched the forums and I do not see any mention of the suitability of a 250GB hard drive as a replacement for a 60GB hard drive in a Titanium Powerbook DVI 1GHz. Here is a link:

http://www.ifixit.com/Apple-Parts/250-GB-5400-RPM-Western-Digital-ATA-Hard-Drive -New/IF107-052

I love this machine, but I am out of room and have only 1.5 GB to spare. The data on this machine I need access to and do not want to archive. My iMac G5 PPC at home has a 250GB, and I would like to sync the data on both.

I guess my real question is, what is the maximum size (storage) that I can place in my Tibook and it function WELL and DEPENDABLY.

Thanks in advance for your input,


iMac G5 2.1 PPC, iMac G4 15in 800, Powerbook G4 1G Titanium, Mac OS X (10.4.11), iPod 3G, Treo 650

    Hi, Dani. Yes, that drive is compatible with your 1GHz Tibook. Most slower Tibooks and all G3 models would be unable to use more than 128GB of it; the 867MHz model released at the same time as yours is a possible exception. iFixit should not advertise the drive as compatible with all G3 and G4 Powerbooks; that's misleading because of the 128GB limitation noted above.

    If you ever have any reason to start your Tibook up in OS 9, bear in mind that OS 9 can't start up from any volume larger than about 190GB. It can read and write data from/to larger volumes, but they can't be made bootable in OS 9. Therefore, if you intend sometimes to start the PB up in OS 9, you'll need to create a smaller partition on the 250GB drive on which to install OS 9. It will also be important to install OS 9 drivers on both partitions if you want OS 9 to "see" them both. These issues are only important if you plan to start up in OS 9 — if you always start up in OS X and use OS 9 only in Classic mode (or not at all), you can disregard this paragraph.

    Thank you for the quick reply, eww.

    That is good news and good information. I had actually forgotten that I could start up in OS 9. I really have no need. Only one program do I use that requires OS 9 and it works in Classic mode. (I just did it for fun, though. I had forgotten how fun all the 'clicky' sounds could be!)

    Could I suffer any performance issues related to the large size? Would I be less likely to experience any issues with a 160GB?

    Thanks again for your help,

    Hi, dani. I think the only issue you'd be more likely to experience with the 250GB drive than a 160 is sticker shock: You pay a high premium for the bigger drive, on a per-GB basis. If you don't mind paying just over $1/GB (incl. shipping), then go for it.

    There should be no performance difference between a 160 and the 250. And either one, at 5400 RPM, will be noticeably faster than your original 60GB 4200 RPM drive.

    Could you document what you said about a maximum size for an OS9 startup disk? I know that Apple has stated that the OS9 disk driver used with some of the desk top Macs will handle up to 200GB. I think that number reflects the size of then available drives not any real limit in the driver.

    Hi, Hardy. Apple has no documentation, as far as I know, that is really clear as to the 200GB (unformatted; about 190GB formatted is safe) limit on volume size for booting OS 9. My post above is the result of multiple long discussions and much debate in the OS 9 forums over the last several years, and represents my distillation of the cumulative wisdom and experience posted there. Don Archibald could probably help you out with good citations from his personal knowledgebase and his inexhaustible trove of saved old threads and posts. I'm not systematic enough to have saved links to everything that might be relevant.

    i put a 250 gb Western digital drive in my Powerbook 667 and it works fine

    Hi, Rich. Is the full capacity of the drive recognized? Which of the two 667MHz Tibooks do you have: the Gigabit Ethernet or the DVI model?

    Yes it should work, but the price is nicer here:
