| 615562 | 2007-11-27 02:12:00 | in Acronis Disc Director.(and True Image). Any ideas on what might happen if I select to reverse these settings,(with ADD) as I understand that the primary is the one to boot off? This is how it came to me from the builder 2 years ago.I'm aiming to make a clone of the drive as a backup,seeing how I've just had to install a new drive for a friend.Luckily I had made an image of her drive a few weeks ago, so she just lost some emails. I've already done a clone onto a new 320G drive, which reminded me that the partitions are aaf. Thanks. |

| 615563 | 2007-11-27 02:53:00 | The "primary" and "logical" descriptions are indications of the type of partitions you have . You can have only four partitions on a physical disk, either "primary" or "extended" . A primary partition is a single "disk" . Extended partitions were "invented" because physical disk capacities grew faster than DOS's ability to handle them . ;) An extended partition can contain a number of logical partitions, each of which is a "disk" . If you do fdisk /status you should see that the C "disk" is marked as "bootable" . That is what determines which "disk" is booted from (or where a boot manager is to be found) . |

| 615564 | 2007-11-27 04:58:00 | Thanks Graham. Acronis Disk Director is showing on my first drive.... Disk 1 Unallocated 7MB NTFS(C) 55GB........................coloured as a logical partition Local disc (D) Pri,Act. 98GB....coloured as a primary partition Disk 2 First E (E).....Pri,Act. 232GB...............coloured as a primary partition So I'm assuming that C drive is an extended partition containing a logical partition? The main thing I want to know is if I do a clone of the present setup to another drive will it still work ok? I know, try it and see!! Trouble is I like things to be as they should be!! Not sure how to do an fdisk/status.:confused: Looks a little dangerous! |

| 615565 | 2007-11-29 02:13:00 | fdisk /status is the safest way to run fdisk from the command line . It doesn't want any keyboard input . It just shows the disk status . Your "C disk" is the only logical drive in an extended partition . It's unnecessary for it to be in an extended partition, but that doesn't do any harm, either . The information in the partition table is looked at once by the boot code in the BIOS, then onvcce by the OS which needs to know ehere "disks" are . A clone should be exactly the same . ;) |

| 615566 | 2007-11-29 03:27:00 | Thanks Graham,I'll sleep better now:D Have a friend who swears black and blue that C/boot drive can only be on a primary partition. Still trying to work out how to do the fdisk /status on my XP.Just had a look on Google and this post is shown there.Scary. Thanks again. |
