new HDD

[lazyeye]

i just got a 4.55GB seagete ST34571WC , other system stats are A2000 KS 2.04, AmiOS 2.1, A2091 V7.0 roms.


i goto auto set up drive but hd tools does not read the drive info. when i manualy put in the settings it says the drive is like 1.3 gb,
then numbers i could find out for it are this Cylinders 5178, heads 10, and sectors 512 .

does this perhaps sound like an issue with maybe i do not got 7.0 roms ?


when all this info is entered the drive shows up as a 1.3 gb drive. so here i am asking some of the knowlegeble people what can i doo to get the 4 gb out of this drive ? as i understand 7.0 roms can handle 4 gb drives. so if any of you know of issues

The numbers you quote are the physical geometry of the drive, this is not what you have to enter into HDToolbox. 512 ist not the number of sectors but the number of bytes per sector.

What does it do if you try to read the drive info ?

Do you have the install disk of Workbench 3.1 at hand ? You should use its HDToolbox, it's more advanced.

Or try HDInstTool from Aminet.

Or you could just enter these values:

Cylinders = 8322
Heads = 16
Sectors per track = 63
Sectors per cylinder = 1008

This will create a logical 4GB drive which will perfectly fit onto your physical 4.5GB drive and there is no danger to partition an area outside the first 4GB of the drive (which would lead to data loss).

i tried what you suggested thomas with the drive numbers , wich afterwards i got a negative value and then the hdinst from aminet.net do not got an os 3.1 disc but the best i seem to be able to get is 1.3gb of the drive. so it has me wondering if the roms i got are realy 7.0 , labels do not look like standard cbm labels like my 6.6 roms does this seem like maybe a 6.6 version limit or does it not seem the same, could it be an issue with the particular drive model ?

Boot from a Workbench disk (or hard drive if you still have one), open a CLI/Shell and type version scsi.device
This should tell you what ROM's you have.
You are right; HDToolbox can, and often does report negative values when partitioning a large(r) drive. This does not seem to be a problem; just make the partitions like you want them, reboot and format them.

[Thomas]

Every number bigger than 2GB will be reported as negative, be it HDD size or partition size. This is not an issue of wrong ROMs but a matter of using very old software. Back then nobody could imagine that ever a HDD larger than 500 MB would exist. Therefore nobody took care of integer overflows, either.

This is normal and does not harm. The only disadvantage is that you have to guess what the real numbers could be.

BTW, the numbers you entered result in a 12.6 GB drive, not 1.3GB. That's the same issue as with the negative values: numbers larger than 4GB wrap around to 0.

thanks all for the help . it was just a case of being to damn tired while trying to do things i need to think to do, got it setup and working groovy.

in the morin things worked and made since thanks all



also if i have KS2.04 could i install os 3.1 on my A2000?

No, you can't. Most new features of Workbench 3.1 need functions only available in Kickstart 3.0+. Those parts of WB 3.1 which work on Kick 2.0 are already present in WB 2.1.
