Whoa; and wait a second; how could formatting a disk fix the ATA problem? Is this like extended or expanded memory--ie mapping sectors arount? After formatting will it work in OSX? Will it work on a Beige G3?
All the answers are here at Intech USA; <http://www.speedtools.com/XNews.html>
Here is a (not so) brief clip from the pages that answer your questions.
For customers using extended capacity (over 128 GB) ATA drives under OS X:
Good news for MacOS X 10.2 and later users:
Our initial testing with MacOS X 10.2 and later (Jaguar) indicates perfect compatibility between extended capacity drives set up by HDST 3.5 when running under OS X 10.2. Therefore, our recommendations are as follows:
1. If you plan on running your extended capacity drive in Classic versions of MacOS only OR plan to use the drive with BOTH OS's, you should set up the drive with HDST.
2. If you plan to use the drive with MacOS X exclusively, Intech recommends that you set up the drive under MacOS X 10.2 or later with the Disk Utility software provided with MacOS X.
IMPORTANT NOTES FOR MacOS X 10.0 through 10.1.5 USERS:
As of HDST 3.5, ATA-6 drives of up to 2048 GB connected to the built-in ATA bus are supported while running the Classic (OS 9.X and earlier) versions of MacOS. However, as of MacOS X 10.1.5, these same drives are not supported past the old 128 GB limit. Here are our suggestions for handling this disparity:
1. If you plan on running your extended capacity drive in Classic versions of MacOS only, you can set up the drive without restriction.
2. If you plan to use the drive with MacOS X exclusively, Intech recommends that you set up the drive under MacOS X with the Disk Utility software provided with MacOS X. Note that under current versions of MacOS X your extended ATA drive will be treated as a 128 GB drive. All other space on the drive will be unusable.
3. If you plan to use the drive in BOTH MacOS Classic and MacOS X, it is best to observe the following simple guidelines. For volumes you wish to share between all versions of MacOS keep the total capacity BELOW 131,000 MB. (Notice that 131,000 MB divided by 1024 yields 128 GB, the current limit of OS X on the internal ATA bus) Volumes above 131,000 MB will not be accessible under OS X. Furthermore, do NOT allow any single volume to span the 131,000 MB limit!
To create a partition scheme which will function correctly under both OS's, run HDST and select your extended capacity ATA drive in the main window. Go to the "Volumes" pull-down menu and select the "Create/Delete Volumes" item. If the drive is not set up for the MacOS yet, the drive will automatically be prepared for new MacOS partitions for you. From the "Create/Delete" dialog, you can create volumes in any arrangement UP TO A MAXIMUM OF , that will still be FULLY supported under MacOS X. IMPORTANT NOTE: It is STRONGLY recommended that you allocate space for MacOS volumes in such a way that the total space for volumes you want to share between MacOS Classic and MacOS X are EXACTLY EQUAL TO 131,000 MB. This will prevent any accidental data loss on a volume that spans the 128 GB limit.
Here is a simple example setup. Let's say you have a 160 GB ATA drive connected to your built-in Ultra DMA/66 bus. The easiest way to share data between MacOS 9.x and OS X 10.x would be this: in the "Create/Delete" dialog create a 131,000 MB volume. Then with the space remaining, create another volume. When running Classic MacOS, both volumes will be visible and fully functional. When running MacOS X, the first volume will be visible and fully functional, but the second volume will not show up, and, therefore, will not be subject to any data loss or corruption.
