MAC se/30 HD formatting problem

[ystone21]

Hello,
I am a totally mac newbie recently bought a mac se/30. An old dream... ;-)
I have the following problem and any kind of help will be welcome.
The HD is 20mo and has an unknown password preventing launch any software install and look for a network connection.
By clilcking cancel i can access to the hd but can't launch anything.
I try to use the hd utility available in the system to format or erase it, but i recoverd an "impossible to unmount the volume".
I install system 7.0.1 with floppy disks for same result...
I fiight and try lot of thing without a result.
Would any of you have an idea/solution ?
Thank you in advance.
Regards.
Eric

I guess a good first question for you would be:

1) do you need to keep anything on the current drive?

If the answer is "no," I would download a program named "Lido" from Macintosh Garden or the like. It should be small enough to fit on a floppy disk along with a minimum system folder (say system 6.0.8) and it should format the SCSI drive no problem. Or if you dont mind juggling disks, you might be able to boot from the 7.0.1 install disk. I don't know for sure. You can eject startup floppy disks with system 6.0.x anyway.

If the answer is "yes" then things get complicated.

Also, welcome to the forum!

Good grief, that must be an insane protection software. Jessenator's suggestion is a good one. If you have any other old Macs, you can also try and attach the HD to that one and work on it that way.

Thank you for your answers.
I do not care about hd datas.

I download Lido 7.56hqx and put it on floppy (via hfvexplorer and winimage). 

The Mac system 7 recognize the floppy and unzip fine the hqx.
I run Lido and obtain an impossible format message. Because of system install on hd... 
I have tried with other hd utility (hd sc 7.35, hardisk utilities, scsi probe 5.12)... same no result... ;-(
As i previously said i am not at all a mac expert.
But i remember that in the pc world, around the beginning of 90's there was some low-level format software for hd.
Do you know if such tools exists for Mac ?
Or another way to solve this problem...
Thank you very much for your attention and help.
