A600 HardDrives >4GB

[alexh]

I'm sure this subject has been talked to death, I've done a little research before writing this.

I have a 2Mb A600 vanilla 68000, KS3.1 (40.63), 20Gig internal IDE drive.

I've run the following two programs

>check4gb scsi.device 0
scsi.device unit 0 supports TD64 commands
scsi.device unit 0 supports SCSI-Direct commands

I've got v40.5 of scsi.device

>checkhd
Name    Volume    Device      Unit Size   >4GB DosType  Version
HD0     Workbench scsi.device  0   499 MB  No  DOS\03    40.1    ok
HD2     Workbench scsi.device  0  1.53 GB  No  DOS\03    40.1    ok

Where do I go from here? I guess a need a newer version of FFS. Can I get one for 68000?

Do I also need a newer version of HDToolbox (v40.4)? I can only see 2GB with the current one (or will that fix itself with a newer version of FFS?)

Any suggestions appreciated.

Bear in mind that I cannot use OS3.5+ OR SFS as I dont have a 68020+ CPU.

This is strange. Have you installed IDEfix or something ?

Do I also need a newer version of HDToolbox (v40.4)? I can only see 2GB with the current one (or will that fix itself with a newer version of FFS?)

This might or might not be correct. HDToolbox calculates everything above 4GB wrong, so you have to check it yourself. Get the capacity data from the case of the HDD or from the manufacturer's homepage and check if the data HDToolbox read from the disk is correct.

The total number of blocks, calculated from heads * cylinders * sectors, should be around 40,000,000.

After that HDToolbox should see the entire disk.

Create a <2GB boot partition (500MB will be enough for all future purposes) and install IDEfix on it (as you probably already have done). Then get the FFSTD64 patch from Aminet and install the patched FFS with HDToolbox's Add/Update button. Now you can partition the rest of the drive. However, IIRC there is still a limit for partitions which is either 2GB or 8GB, I don't know.

I dont have anything installed... however my workbench disks are marked v3.11 (dunno if that matters)?

It's an IBM DTNA 22160 2.5" drive.

The Harddisk says 4200 cylinders.

HDToolbox says

Partition HD0
Start Cyl:    2
End Cyl:   1014
Total Cyl: 1015

Partition HD1
Start Cyl: 1016
End Cyl:   4199
Total Cyl: 3184

I think I've screwed up.... I think my drive is only 2.1 gig

I wondered why it was only £5

You have to click on "change drive type" first, then on "define new" and on "read configuration". There you have to check the values for cylinders, heads and sectors. These values define the real capacity of the drive. And you have to press enter or tab after you changed any input field, otherwise the change will not be taken.

And yes, the drive is only 2GB. So you don't need to worry about the 4GB limit. :-)
