Why is it that fdisk sometimes deletes partitons when I did not ask it to change anything? Merely asking fdisk to look at a hard drive on my computer seems to be dangerous. I would like to know what is wrong with the command below:
/sbin/fdisk /dev/hdb -l
I was trying to use that to see what partitions I had on my second hard drive. It gave me that info and also gave me this message:
Warning: deleting partitions after 16
I did not want it to delete any partitions.
Which part of the above command tells it to delete any partition numbered higher than 16. Fortunately
I did not have anything important on my last couple of partitons. I assume it actually did delete them although I can not remember how many I had to start with? Fortunately, all my of my various operating systems still seem to boot up ok. I was using Red Hat 9 at the time. To make sure I am describing what I did above, I carefully cut and pasted the exact command I used and a portion of response into this message.
I had a similar, but worse experience about two months ago when I tried to intall the latest version of Slackware. I believe it was Slackware that I was using at the time. If I remember correctly, I used this command to try and look at drive g:
Part of the response was that some of my partitions were being deleted.
I do actually have a drive g on my computer by the way. The motherboard in my computer is designed to connect up to 8 IDE devices. I currently have 6 IDE devices connected to this computer.
Fortunately, there was nothing important on that hard drive. The entire disk merely contained backup copies of various partitions. I still had the original copies of the partions on other hard drives. When I used Partition Magic to examine hdg I found that approximately 100 GB from three extended partition had been deleted.
I have mostly just used Partition Magic and Disk Druid for partitioning and do not yet know much about fdisk.
What did I do wrong in the above command?
