Titolo: Massima capacita' dischi rigidi e OS Apple

Ho appena visto che la Maxtor ha rilasciato un hard disk da 320Gb.
Sono curioso di sapere se il Macintosh e' in grado di sfruttare tutto
questo spazio in un'unica partizione.
Qual'e' il limite di OS X ?
E quello di OS 9 ?
Grazie per l'attenzione.

Ciao da Francesco B.

 E quello di OS 9 ?
Non vorrei dire una cazzata, ma credo che con l'arrivo del HFS+ (era 
MacOS8?) i limiti siano stati innalzati a livelli che non dovrebbero 
creare alcun problema ancora pe run bel po'...
ciao ciao

 creare alcun problema ancora pe run bel po'...
Innanzitutto grazie della risposta.
Ho guardato or ora sul sito 
www.xlr8yourmac.com
 dove viene data
un'indicazione proprio sul disco della maxtor e i computer Apple.
Se non ho capito male alcuni Macintosh che hanno ancora la rom
potrebbero avere problemi e non superare i 128Gb anche utilizzando i
sistemi operativi piu' recenti.
In pratica il problema potrebbe essere superato con un controller
aggiuntivo.
Quindi credo che: iMac, G3 blu e bianchi, G4, iBook, Powerbook non
dovrebbero avere problemi a leggere partizioni cosi' grandi.

 OS 9 ?
Il limite non penso che sia il sistema operativo utilizzato, ma il
driver del controller ATA.

160GB Maxtor Drive Fully Supported by Acard ATA/100 Card Update:
There have been news posts and database entries here previously about
the >128GB IDE drives not being able to be fully utilized (even with
multiple partitions) with either the onboard IDE (ATA/66 at best in
current macs) or the ATA/66-ATA/100 PCI IDE Mac controller cards.
Acard's ATA/133 firmware update (noted some time back here) for their
ATA/100 card was expected to add support (fix the addressing limit) to
fully support these drives, but this is the first (Mac) report I've had
from a 160GB drive owner noting the full drive size was usable.
" Good news...
I got the Maxtor 160gb drive and ran into the problem posted here in
which the drive only formatted to 128gb instead of the full 160gb. I
bought the Acard 6280M from Other World Computing and installed it
today. Out of the box the card did work without a hitch, but the drive
still only formatted to 128gb. I went on to Acard's web site and found a
1.2 driver update (1.0 is the card's current bios version). The update
for OS X is two .kext files that need to be replaced in the system (as
root of course). 
After the update, I ran Disk Utility and the drive now formats at
152.67[GB]!!!
So for anyone who want full compatability for large drives, Acard's
6280M will do the job with the updated drivers.

Since Acard partnered with Maxtor on the ATA/133 card (noted in a press
release earlier this year), I expected the larger drives would be
supported, but good to get verification on that. I searched Acard's site
and here is their page with Mac driver updates. It lists an OS X update
for the 6820/6880 cards and 2.10 firmware updates for the 6280/6880
cards. (I asked Brian if he applied a firmware update and the OS X
update, or just the OS X update. I also asked if the full drive size was
usable in OS 9. (He later replied OS 9 sees the full size now - despite
not flashing the card.)
