250GB drive

I know there is a limit on my Mac Dual 867 for hard drive space, 137 gigs I think, my question is...Is is possible to get a larger drive, lets say a 250 gig and partition it for 125 a piece and have it be usuable? This is running of course on a ATA 100 system. Just wondering if its possible for the system to recognize the one larger drive as 2 smaller ones....
 
The 137 GB limitation is for devices (drives), not volumes. The answer is: No, not without installing an IDE card that will support ATA-6
 
The 137 GB limitation is for devices (drives), not volumes. The answer is: No, not without installing an IDE card that will support ATA-6. (you can put that big drive in an external FW case that supports a big drive (not all cases do) and that will work.)
 
I thought that ATA-100 supported more than 137gig? I know ATA-66 is 127 gig.. seems odd that 100 would only increase the limit by 10 gig
 
Isn't your Dual 867 a MDD unit? If it is, you should have no problem using a 250gig hard drive on the ata-100 cable (the one in the back of the case, not mounted under the optical drive(s).)

I have a dual 1 GHz MDD and I have a western digital 250 gig hard drive hooked up to the ata-100 cable, and I'm able to see/use the whole drive, no partitioning necessary (unless you want to.)
 
Are you guys sure the ATA-Type has anything to do with the max size of the disc plugged to that controller? I don't think so, but I am not absolutly sure. I thought it's a matter of the os. There are some filesystems of some os types that simply can't handle capacities beyond a limit. However, macosx can do and since I always read: 250Gb ATA133 and below... :confused:
So, my thought is it should work. Correct me if I am wrong.
 
Sorry, I mis-read the first post. The Dual 867 is a MDD model, which would support 48-bit LBA (supports over 137 GBytes (decimal), or 128 GB (binary) for the math-conscious folks)
Bottom line, a 250 GB internal drive should work great.

Oh, the ATA-6 specs allow for 144 PB of storage on one drive (lots of zeroes in that one)
 
So the ATA-6 Spec is whats commonly known as ata-133? what does ata-5 (100) support as maximum drive size?
 
How confusing can this get? According to charts on THIS PAGE, ATA-5 spec maxes out at ATA/66. If an interface is ATA/100, that would be ATA-6 spec, or UltraDMA mode 5.
UltraDMA mode 6 is still ATA-6, but on an interface that is ATA/133

ATA-5 does not provide support for drives larger than 128 GiB, and does not provide for an interface speed faster than 66 Mhz, and provides operation with UltraDMA mode-4
:D
 
Don't know about the ATA limit thing, but what about using an external Firewire drive? I've got a Lacie 200 GB connected via FW400 cable to my DP G4 1 GHZ original model. Runs like lightning. I'd love to see it on a G5 with true FW800 and all the other pipeline benefits.
 
Basic reason why I dont want an external firewire drive is because I dont need it, and its a lot more money. Its just another thing to cludder up my desk. My mac is the Dual 867 Mirrored Drive Doors and It has room for 4 harddrives. I believe the first 2 on the line are ATA66 and the other two are ATA100. Still confused about somethings....I am assuming the drives dont have to be inline? Meaning, I can have one on the ATA66 ribbon and the other on the ATA100 Ribbon? Also, I have been hearing that Maxtor Drives are crap. Anyone have any feedback with these? Most likely I will go with a Western Digital drive but best buy has some great deals on the Maxtor drives.....
 
I have three drives in my G4, two of them are Maxtors, both about 3 years old and don't have any problems. Have a Maxtor in a 6500/300 that's at least 4 years old and has no problems.
 
Do you have a firewire/PCI card? Just get a firewire hard drive and problem solved, as long as the firmware will support the drive you want.
