Largest native scsi 2.5" drives I've seen were 2GB Toshiba-(IIRC) and 
they also made a 1GB model. More common were the Toshiba 800MB drives. 
I've no idea how fast are the 1GB and 2GB drives as I've not owned 
either, but the 800MB ain't no speed demon. The most common 'large' drive 
is the IBM 540MB, available from Apple as OEM shipped in the PB5xx, and 
from the aftermarket as well. Damn expensive at the time too, my memory 
is foggy, but I recall a $1000 area price.

Apple did sell the 1GB IDE-converted-to-SCSI drive as an upgrade for PBs 
5xx, though I have no idea if those actually shipped inside those 'Books 
from the factory. That drive was based on an IBM 12.5mm 1GB ATA mechanism 
and the ADTX IDE-SCSI converter. That converter has an ~8GB drive size 
limit (larger can be used but only 8 are seen) and is dog-slow. My tests 
in a 2300c and a 540c with 2, 4, 6, 8 and 10GB drives showed max transfer 
rates under 500k/s, roughly similar to the IBM 540 and the Tosh 800 
(~550K/s.) The Century adapter (32GB size limit) was much faster, with 
throughput ~ 1.2 MB/s with any of the above ATA drives. For comparison, 
any 2GB or larger ATA drive I tried on a 2300c's IDE bus showed roughly 
double that throughput.

No PB scsi bus is very fast, so I'm not sure how fast the Century 
adapter/large ATA drive combo will be on a Fast (or Ultra) -scsi bus. 
When I do test it I'll mention the results here.

I've only ever seen the Caldrives item at the US$150 price so was excited 
to see the $99 mention. Perhaps 'twas a sale or special or suchlike?

The OP needs a larger drive for their PB1xx, and I think a 240 or 320mb 
unit ought to serve well and shouldn't cost too much on eBay. Important 
thing with these old drives is to purchase either _very_ cheaply or get 
at least a no-DOA warranty from the seller.

If you take that route, bear in mind that the PowerBook 150 and 190 use IDE
drives.

The largest SCSI drives can be found in the 500 series. Rumour has it that
late PowerBook 500 series models were shipped with IDE drives and SCSI-IDE
converters. That would be the 500 MB models, then; I have a rather late 320
MB model that came with a native SCSI HD.

You do need to be looking for a "notebook" drive, 2.5 inch SCSI. In 
addition to checking eBay for the drives, you might check for 100 
series Powerbooks that are being sold for parts.  Also, the LEM swap 
list will no doubt turn one up. You should be able to go up to 2 GB 
with no problems.

Might be time to think about a regular 50 pin drive in an external case, to
be cost-effective. www.macsales.com:  4 gig Apple drive $59, 540meg drive
$11, if you have your own case or can find one at a "used" store it's easy
to swap drives around.  How big a drive you can use might depend a little
on the OS/powerbook model.

Any of the seriously older ones are going to be 2.5" SCSI which are very 
rare.  Search E-Bay for them.

The other option is to spend for an IDE->SCSI converter.  They are out 
there and will work with the Powerbooks that exist.  I'm not sure what 
you're going to pay but it is an option.

More thoughts on the PB170 HD

[Leigh Honeywell]

In that, maybe I should jsut get a bigger one.  Searched high and lo on 
Google, but couldn't figure this out - are the hard drives in the 
powerbooks just standard SCSI drives, or should I be looking for 
specifically a "notebook" drive?

Thanks
