do you have an 80gig maxtor diamondmax plus 9 hd set up with hdtoolbox? then PLS help!

According to http://www.maxtor.com/en/products/ata/desktop/diamondmax_plus_9/model_numbers_table.htm the data of your hdd should be as follows:

heads: 16 (= tracks per cylinder)
sectors: 63 (= blocks per track)
cylinders: 158,816
blocks per cylinder: 1,008 (= blocks per track * tracks per cylinder)
total number of blocks: 160,086,528 (heads * sectors * cylinders)
bytes per block: 512 (assumed by me)
hdd size in bytes: 81,964,302,336 (number of blocks * block size)
hdd size in gigabytes: 76.34 (bytes/1024/1024/1024)

Now, the only value that really counts is the total number of blocks. The latest version of HDToolbox suggests ca. 1MB per cylinder. The first two cylinders are used for the RDB and it must fit there.
So the number of blocks per cyl should be 2,016 and the number of cylinders 79,408.

Oh, and of course the rules:

if you connect the hdd to the internal IDE bus:

- the boot partition must completely reside below the 4GB limit.
- on the boot partition the required patches must be installed (SetPatch, NSDPatch.cfg, AmigaOS ROM Update)
- you must use a filesystem that supports NSD commands (FFS V44+ or SFS)

For PFS3 you need IDEfix97. It is not true that PFS3ds does not give any problems. The internal scsi.device IDE driver has an 8GB limit for SCSI-Direct commands.

If the hdd is connectred to a Phase5/DCE device (BlizzardPPC, CyberstormPPC etc.) and you use either PFS3, PFS3ds or SFS, there is no limit in boot partition size. You can even create one big 80GB boot partition. For FFS still NSDPatch is needed and thus the boot partition must be below 4GB.

If the hdd is connected to another controller, its rules apply. They can be different or similar, depends on each single controller.

To check if all works as it should (before copying any files) you can download the Check4GB archive and run the program CheckHD.
