Open disk read-only ?? (slack install)


Hello all,

First time poster here and thank you in advance for any help you may be able to provide.

I am stumped and have searched the forums but was unable to find an answer to my problem.

I'm installing a good (installed on other machines) copy of Slackware 10.1 on to a Dell Latitude 100L laptop. I have installed this version of Slackware on other laptops and desktops and have never seen this protection error - "Open disk read-only - you have no permission to write."

Ok basic setup is this.

Dell Latitude 100L laptop - 20gig HD - 256mb ram - partitioned 10gig/10gig with windows XP pro installed on one partition.

Drop Slackware 10.1 in and boot from CD. Slackware comes up and I load the bare.i image. login as root, then try to cfdisk and I get : Open disk read-only - you have no permission to write. At this point it will let me do everything in cfdisk but Write. Same thing happens when I try to fdisk.

So I completely format the PC using windows XP pro, Drop the Slackware 10.1 cd in and bootup, same error.

Partitioned the HD back into 2 10gig partitions and install XP back on.

Try something new, I download Fedora core 4 and it installs like a champ. So now I have XP and Fedora installed on there own 10 gig partitions respectfully and use GRUB as the boot loader.

Well I figure since Fedora installed fine, maybe I can drop in the Slackware 10.1 CD again and blow away the fedora and install slack. Drop in the Slackware CD, load bare.i, type in root, cfdisk and Open disk read-only - you have no permission to write..... sigh.

What do you guys/gals think?

Thank you again and any response is appreciated.

Angry FDisk/CFDisk Open Read Only

I'm having this exact same problem with an old Gateway desktop and Slackware 10.2. This machine has 256MB Ram, 14gig HD and 1 30gig HD. Both drives open Read-only. Does anybody have a solution, besides abandoning Slackware?

I'm having this problem as well on a brand new Asus Laptop. Vista installed. I have about 70 gigs of raw space on the drive that were de-allocated from my Vista partition. Tried leaving it unallocated, partitioning as raw space, formatting as fat32.. makes no difference. Still get "open disk read only - you have no permission to write" from cfdisk. passing this error screen, cfdisk shows none of the partitions onthe disk and claims that I have ~4 gigs available to use (where is this number from?). Also tried changing every option in bios related to disks. Same error.

Any suggestions would be appreciated.

This is my first post. Hello to everyone! =]

Ok, I figured this one out. I installed Ubuntu to see what it could tell me about my disk system. I noticed that it referred to the cd drive as /hda and to the hard drive as /sda, so in the Slack install i used fdisk instead of cfdisk and had it list the table for dev/sda instead of dev/hda (the default in cfdisk) and Tada!, there were my partitions.

That is also why cfdisk reported the drive size of dev/hda to be about 4 gigs, because I had a dvd in the drive. (I should have clued in to that before, but I didn't )

Since Ubuntu formatted my two partitions during its install, I skipped the fdisk step and just installed Slack over Ubuntu.

to summarize, anyone who gets the "open disk read only - you have no permission to write" error from cfdisk, it's probably because cfdisk has defaulted to the wrong disk designator.

you only need to add this command in the prompt cfdisk /dev/sda and it will start with that disk ... after that u know what to do!!!
