cfdisk on slackware

[debojitkakoti]

frndz.....i want to install slackware...
bt i got this error when i used cfdisk to partition...pls help me out
"opened disk read only-you have no permission to write"

i have sent snapshot below.........

[reed9]

Your snapshot is too small for me to read, but my first thought is, did you run cfdisk as root? And did you run it with the drive unmounted?

[debojitkakoti]

ya........as a root...

i used to install it on vmware...and my os xp....

thanks reed9...
is this bezoz of NTFS file system????

[reed9]

It may be, though I would think you could delete and reformat a NTFS formatted drive with cfdisk.

You might want to use something like Parted Magic to partition your drives for Slackware before the install.

Can you give some more details? How are you running cfdisk, from the installer, or from an existing system, or inside a virtual machine??

Also, a lot of problems with the *fdisk family arise from the default device *fdisk attempts to partition:
When your CD-ROM is ATA and your HD is SATA, then the kernel calls your CD-ROM /dev/hda and your HD /dev/sda. When you run cfdisk without arguments it will default to /dev/hda and hence attempt to partition your CD-ROM. Which fails, because CD-ROMs are read only

Running `cfdisk /dev/sda` would do the trick (if this was indeed the problem).

Running these commands will tell you more about what is what:

fdisk -l
mount
