Hi all,

I had recently tried to install Debian on a computer containing a 200
GB harddrive. However, during cfdisking of the Debian install process
cfdisk fails to see past approximately 130 GB of hard disk space. I'm
suspecting this is because it is an old version of cfdisk (later
versions of cfdisk seem to see the whole drive). So, does anyone here
know how to work around this problem so I can use all of my hard disk
space with Debian? Thanks for your help!

Please set your mailer/editor linewrap to 68-75 characters.  I strongly
recommend 72 as a good default.

Thank you.

See the Large Disk HOWTO.  There's a history of successivly larger disk
sizes which require different mechanisms for handling what was initially
a 528 MiB limit for HD sizes.

I have a similar problem so I read the large disk howto (again) but it's pretty much irrelevant today...

For disks beyond 137 GiB, the HOWTO doesn't provide specific guidance,
though a good overview is here, in general, you want 2.4.18 or better


in addition to that: I have SATA disk (250GB), seen as scsi device (kernel scsi ata configuration option enabled), for which you need at least 2.4.21-ac4, most tools see the whole disk but can't read above 137GB, here's the latest from lkml:

Can you test Alan Cox's 2.6.0-test-ac tree?  I bet the 137GB

  I didn't try it yet so I don't know whether it's going to work...
