 |

I am running ~amd64 if it matters.
When I enter "fdisk -l" I get this | Code: |
fdisk -l
fdisk: cannot open /dev/sr0: No medium found |
Here's the contents of /proc/partitions | Code: |
major minor #blocks name
11 0 1048575 sr0
11 1 1048575 sr1
8 0 488386584 sda
8 1 112423 sda1

I have a second Gentoo install (~amd64 too) which I use to make backups on a USB HD of my "day-to-day" Gentoo.
On this one fdisk -l works as to be expected and /proc/partitions is identical.
Both installs have the same binutils version.
I need fdisk -l for when I want to copy stuff to a USB stick to make sure of the sdx it gets.
(fdisk /dev/sda works fine).
I've tried downgrading binutils but that didn't make any difference.
I am at a loss what causes this.
Thanks in advance for any help.
Gerard.

/dev/s(csi)r(aw) ist most probably not what you want. If recognized, the USB-HDD should be something like /dev/sd?
Look at your dmesg output to get more Information.
/dev/sr0 is most probably a optical drive, a scanner or something like that.

Thanks for answering py-ro.
I apparently didn't make myself clear enough.
The sr0 and sr1 are optical drives (RAM and ROM).
Fdisk shouldn't be reading them.
This is what I should get w/o a USB stick attached. | Code: |

I loaded cd's in both optical drives to make fdisk behave normally.
As you can see they are not listed.
Why does it stop when there's no cd's loaded? It shouldn't.
Gerard.

Well my bad.
Fdisk is not part of binutils but of util-linux.
After downgrading from 2.25 to 2.24.2 fdisk works fine.
