Formatting linux partition

[Pete Peters]

Just to clarify, pdisk is available in both Linux and MacOS versions. They
both have the same basic engine, commands, look 'n' feel. The link below is
for the MacOS version. Works great.

Eric,

Info about Pdisk and using it can be found at the following links;

You can download Pdisk from;

Are we having fun yet?


Pete

Now my next question is:

How do I get to pdisk? I assume I have to be in YDL to run the app, but I
doubt that I will be allowed to format the boot partition.

I have the YDL 2.1 and 2.2 Install CDs and tried booting the 2.1 CD but it
wouldn't let me (failed with some error & said it would restart in 180
seconds (& I wasn't able to command-control-power to restart for the first
time ever (B&W G3, ADB keyboard)... I thought com-ctrl-pwr was a hardware
thing and didn't think software could over-ride it)).

I've mangled the Linux partition (1536 MB) with the installer (trying to
trick it into formatting me one big boot partition). Should I re-install YDL
and try deleting the partition that way (using your pdisk instructions)?

Thanks for all your help, Eric.
