Unable to write partition table

[phnax]

When I try partition my hard drive when installing Slackware I get an error saying that I can't write partition table. When I make a new partition and try to write the table to disk I get 'Unable to write /dev/hda' error. How can I fix this?
Thanks.

which prog do u use to partition ur HHD? Do u specify /dev/hda1 or hda2?

I use fdisk. I type fdisk /dev/hda.
Does it matter if the disk is slave or master?

Where is the new thread button. All I see is post reply. Do you need a certain number of posts in order to start a new thread? Thanks, Angela.

If you are telling fdisk to use hda, that is the same as telling it to partition the primary master.

To be honest I prefer to use cfdisk, you can see all the partitions as you create/edit/delete them.

Just type

cfdisk /dev/hda

I tried cfdisk as well. The problem is when I try to write the partition table to disk, as the disk is read only.

Is it possible that you have some type of AV or some setting at the BIOS level keeping you from changing the partition table?

Could be BIOS level MBR protection for viruses, enabled, as he said.

I doubt it. I tried another harddrive earlier, and it worked fine there. I took it out because it was too small. 1,9GB or something. But I'll check it out.

Try setting the addressing mode for that HDD to LBA32 or AUTO, and see if LILO still complains
