Windows 7: How to extend an Extended Partition; leave logical volumes intact

I assume the app you purchased are the home editions, and come from:
PARAGON Software Group - partition manager, drive backup, hard disk partitioning

The features of Hard Disk Manager 11 Suite look impressive, see
Hard Disk Manager Suite - Disk management: hard disk backup, partitioning, defrag, disposal

From the screenshots of yours, it appears Paragon home editions can format and partition according to Win7 rules; that implies that partitions in Advanced Format Drives (AFDs) are automatically aligned. However, in WinXP it is not obvious at all to create 4KiB aligned partitions/volumes on AFDs. So, have you seen anything in your Paragon (home version) apps which could indicate the Paragon apps are able in a WinXP environment to adjust or align partitions with the 4KiB boundary of an AFD? I've been looking for in the HDM11 features but couldn't the answer.

The same previous question for SSDs? Lot of home users nowadays have an SSD in their laptop, and so will I have in the near future too. It would be handy if the home versions of Paragon could deal with (and optimize) SSD partitions, so that I don't have resort to a more expensive business edition. Also here couldn't find the answer in the HDM11 features.

If you set the option to align according to nt6 rules ( vista and later) it will be fine for SSD and also for 4k512e drives.

If you are running paragon from within XP you may need to set that dropdown under the main screen Settings Tab

For your information, the problem of extending an NTFS extended partition shell (front-end and back-end) while leaving the logical volumes inside the extended partition intact, has been solved. Some time ago, I burnt a live CD with GPartEd v.0.12.02 and booted from it (maybe there is already a later version).
GPartEd can stretch the front and back end of an extended partition while leaving the logical volumes intact/unmoved. Also, GPartEd can do its operations with partition alignment according to NT6 (Win Vista/7) rules, i.e., offsets of multiples of 1 MiB (=2028 X 512 byte sectors), or according to the legacy 63 sector offset system (WinXP and earlier).

If you are able to chuck it into winpe - that is fine.

Otherwise there is not much point bothering with the free paragon.

The paid versions are very good.

That particular one in the photo is backup and recovery 11.

They will be sending me a copy of the next version ( Hard Disk Manager 12 ) in the near future.
I know this is an old thread, but it is a direct bulls eye hit on my dilemma. I have Paragon 11 Suite and a Lenovo V570 laptop with 3 primary partitions (2 of which are hidden proprietary partitions) and 1 extended proprietary partition. The net result is a huge C drive, and 3 inaccessible partitions that, to date, according to the Lenovo community forums, are impossible to re-configure without disabling at least some functionality (One Key Restore, Finger Print Reader, etc.)

At the far left is a 200 MB primary active partition, then there's the huge 655 GB C drive, then the 29 GB extended partition which contains a 29 GB proprietary logical partition, and finally a 14 GB proprietary primary partition. What I would like to be able to do is shrink the huge C drive to around 65 GB, then create one 500 GB logical drive and a second 90 GB logical drive inside the extended partition, bringing the total number of logical drives inside the extended partition to 3.

I'm not particularly tech savvy, but from what I've read, extended partitions should be able to have any number of logical drives in them. But for some reason, no one at Lenovo has been able to figure out how to pull off this reallocation of space, although a number of users would really like to be able to do this. Nobody wants one big "C" drive with system and data all lumped together. The only alternative so far has been to totally nuke the two proprietary drives to the right of "C", and then create more rationally configured partitions. It works -- I've done it -- but some Lenovo features end up being thrown out in the process. I did that with my first V570. I just got a second one and was hoping for a more amicable solution.

There is no problem shrinking the big "C" drive to 65 GB, which then creates 590 GB of unallocated space. The problem is getting that space inside the extended partition. I've worked with Paragon, but not with extended partitions. If there's a way to do this, not only would you make me very happy, but I know you would make a lot of folks with V570's happy as well. Thanks in advance.

NOTE: I use Paragon outside of Windows, run off a bootable CD. It's slower, but it's less problematic.

Could you start Disk Management, expand it to maximum width, take a screenshot and put it on the forum. It makes things clearer.

Sure. N/P.

Note: Also, like DiracDeBroglie, I need to keep the contents of the 29 GB Lenovo logical drive that's already on the extended partition intact.

Use the cool new Partition Wizard boot CD Extend feature which allows you to add/subtract from any other partition even if it's not adjacent, plus PW always treats Primary and Logical the same for resizing purposes: How to extend partition easily with Partition Wizard - video help.

Remember that you're only required to keep the OEM partitions if you intend to use the factory image which is a corrupt install to begin with, and which no tech enthusiast would keep. Instead you can make your Recovery disks and then delete all partitions to create new as you wish during a Clean Reinstall - Factory OEM Windows 7.

So you want to shrink the C partition, which is not a problem in DM, and shift the BEGINNING of the Extented partition (dark green encapsulation) towards the left, absorbing all the newly created unallocated space, thereby leaving the D partition untouched.

The answer is in my last post #24, just prior to your first post. Your problem can be solved using GParted, which you can downloaded from:
GParted -- About

Burn a Live CD/USB from it and boot into GParted. You'll see a DM like representation of the partitions of the internal HDD. If you have already shrunk the C partition to 65GB then next is to move the beginning of Extended partition to the left.

In GParted, just click the /dev/sda3 |_| extended line and in the graphical representation on top you'll see a dashed line popping up which encapsulates all that is inside the extended partition (that is, the D logical partition and some unallocated space in your specific case).

Then in the menu go to Partition->Resize/Move and stretch the left side of the extended partition completely to the left, encapsulating all the unallocated space. NOTE, as you are using Win7 the partition alignment goes in steps of 2048 sectors, meaning in blocks of 1MiB assuming sectors of 512 bytes. HENCE that you need to put the option Align to: MiB. Do NOT leave the option on Cylinder (which is the legacy 63 sector alignment prior to Win Vista) or on None. Put the option for sure on MiB!!

Finish the operation by going in the menu Edit->Apply All Operations and you should be set.

Also, prior to doing all this: BACKUP ALL YOUR DATA!!

If you're not sure about the partition alignment scheme that is being used on your HDD, right-click /dev/sda3 |_| extended and show Information. A new Info pane shows up with at the bottom info about the First Sector, Last Sector and Total Sectors. Take the numbers of First Sector and Total Sectors and divide those numbers by 2048: it the outcome is a round figure (integer), then the partition scheme is a 2048-sector partition scheme and the option |Align to| must be set on MiB. If you doubt, copy the numbers into this forum and we'll see.

If you're not comfortable with all this, or are not at all to sure, you can test GParted on an old external Hard Drive of even an USB flash drive. Best is to experiment with an old HDD, which you can buy from any website for a few dollars, put it into an external USB enclosure and you're all set to go for the most entertaining experiments. GPared will definitely see any USB external HDD, if at least, the enclosure has a USB 2.0 port; USB 3.0 ports could be a problem for GParted.

Let us know how it went, ok. I've been using GParted a lot for those kind of operations and it all worked fine.
