Getting an ST-225 drive to work on an ibm portable

[soviet9922]

This is my first time dealing with these very old drives.
I have an ST-225 drive and use a segate11m/11R 8 bit controller.
The drive will do all the proper noises when starting and will ask "your c drive has not been insstalled" "do you want to install the unit? (y/n)"
Then the bios "2.1" will show a message "Total cylinders on the drive ......", and seems to be stuck there don't hear the drive doing anything the led is dark.
And the is stuck there calling the program from debug could do the same.

Open to any suggestions!
Thanks.

Are you sure you have the cables on the right way around? If I recall correctly some ST11 don’t have very clear markings for pin 1 on the two headers.

I'm such a dummy
The program was waiting for my input! xD.
Ok now entered all the data for my drive
The drive will ask for an error map but deres nothing on the top of my drive so I choose no.
It will format ok and then when the verification starts will complain "Bad drive !!! [4]" after a few cylinders.
So this drive is bad, have to trash it?

So presumably, the 'format' bit just blindly writes only, with the 'verification' bit being when the sectors are read back.

You wrote, "a few cylinders". If you remove the data cable, does the abort happen after only one cylinder? If instead, you see exactly the same behaviour as before ("a few cylinders") then the suspects become:
- bad data cable
- good data cable, but not properly connected
- Bad ST11 (read circuitry)
- Bad drive
