Resize Partition Failure (Part 2) - PW Partition Recovery found issues

Since I'm not an expert at present, I can't do a lot to help others in this forum solve their problems. So I figure that the most helpful thing I can do is post enough information that hopefully others can learn from my experiences. That's why I'm putting so much documentation into this thread.

I have a WD 2TB external hard drive that I use for both System Image and data file backups. A week ago, I was trying to resize one of its partitions, and the process got hung up partway through. I took some steps to try to address any problems that may have resulted, but apparently I didn't do enough.

Here's the background:

The process apparently stopped at the "Rebuilding Partitions Info" stage - neither the percent complete, nor the elapsed time, nor the time had remaining changed for at least the past 3-4 hours. (Until it suddenly stopped, the elapsed time had been steadily growing.)

I've attached a screenshot showing the Paragon dashboard and status windows.

- I was able to close the Paragon app and its various windows without having to force it to close
- I was able to reboot my laptop without having to force anything to close
- Upon reboot, I could see all of my partitions, both on my internal drive and my external drive

I immediately ran CHKDSK on each partition, and each one passed with no errors except for the partition I had been trying to re-size.
- It had a corrupt attribute that said it was fixed, and part of the free space was changed to show as being allocated.
- When I checked that space through Disk Management, it had been set up as its own partition rather than being added to the partition I was trying to expand, and in fact several sections of unallocated space were showing up in odd places - but the partitions that hold data appeared to be intact and the same size as they were before I started, and I could see the files and folders that had been there before

I read about PW Partition Recovery in one of the tutorials, so I ran a Quick Scan of the entire 2TB drive, with the following results (see screen shot).

I'm looking for recommendations for how to proceed, since I have never used Partition Recovery or Rebuild MBR. (So far I have done nothing except run CHKDSK and do the Quick Scan.) I'm not sure how to interpret the scan results I'm seeing.

For instance,

-Since the drive sizes for "Existing" versus "Lost/Deleted" show as the same but the LBAs don't match in all cases, is it possible that the issue is a problem with the MBR rather than the partitions themselves?

-If it is, should I try to rebuild the MBR?

-I've heard about "aligned" versus "unaligned" partitions, but I don't know how to tell if somehow any of my partitions got "unaligned" during the original failure. If that's the case, I also don't know how to fix it.

-Do I need to do a Deep Scan to get more information, or does the data I already have give enough info to know how to fix this?


If I need to move my data to another machine, I can do so. If I need to completely redo the partitions from scratch, I guess I can do that too. But first I really could use some guidance.

Well, based on the fact that this drive will be my primary back up storage device, the main recommendation I've received is

- move any data that I want to keep to alternate storage
- completely reformat this drive
- establish new partitions
- move the saved data back to this drive

Since I still am not sure what the PW Quick Scan results (plus the other data I've provided) would indicate as my best course of action, I'll start the process outlined above.

I've now moved all my data off my external HDD, so I can do whatever is needed. I also did a bunch of research - tutorials on this thread, information in Windows Help and Support, plus tutorials on the Western Digital and Partition Wizard web sites.

The status right now is I think my partitions have errors and my MBR may be corrupted; in addition, I've decided I want to change the number of partitions I want to have as well as the size and position of each (I'm trying to plan for the chance that I may need to resize one or more partitions in the future, so I want to line things up to make it easy if I can).

I believe the steps I need to take are the following, in the order listed, and I plan to use PW to do it:
-Delete all my existing partitions
-Initialize my drive to an MBR disc since that's what it currently is (rather than changing to GPT)
-Create and format each partition, and then repeat until all my new partitions are established.
(NOTE: This drive will not be used to boot up anything, so my intent is that all partitions on this drive will be Logical (rather than Primary) and none will be Active.)

If I am missing something or I have the steps in the wrong order or there is something else I should be doing, please share your thoughts as I am no expert.
--(For instance, if I should reconsider my plan and have at least one partition on this drive be a Primary partition I can certainly look at doing that, but please explain why that's necessary in this case if you make that suggestion since I'm really trying to learn this stuff)

I plan to do this on Saturday (tomorrow) and I will post what happens.

Are you going to have this HD always connected for daily use, and backups ?

If this HD is just to be used as a "Backup" device, I suggest creating one single partition and use folders to manage data.
My large "Backup HD's" are usually offline, maybe online a couple of hours per month.
What i've learned over the years, it's not worth the effort to partition backup drives, and worry about partition sizes.
I don't care about defragging, if a backup image has 2 fragments, it doesn't affect my performance.
If a large video file has 2 fragments, it doesn't affect my performance.

Also, I don't run "regular security scans" on these storage devices.
Everything was scanned before i "saved" any data to the offline backup HD.

Keeping "Backup devices" offline protects them from malware, power glitches that could kill them, etc.

With a 2TB Backup HD i would intialize it as MBR, create one Logical partition, and create folders as i see fit ...

Personally, i also run a Diskpart Clean on any HD I am reusing to clear any remaining MBR code.

FWIW I've used the Rebuild MBR function in PW on numerous occasions. It has restored functionality several times, and when it did not, it did not do any other harm. In other words, there is no downside to giving it a try.

Wow - a lot of good info - let me try to respond

-The drive will be offline the majority of the time - precisely for the safety reasons you mentioned(malware, power hits, etc.). I plug it in while doing my backups and then put it away when I'm not either backing up or retrieving images or data.

-I use this device to backup my 3 devices (two laptops and 1 desktop). I had planned to create a partition for each device, but I certainly don't have to do so.

-I guess I thought that I should use partitions for two reasons:
++ First, somewhere in the past I was given to understand that smaller partitions make more efficient use of a large physical drive - something to do with the cluster sizes that get assigned based on the drive size.

When I searched for that info just now to provide a reference, I found it in an old article (2003) so I'm wondering - is this still true? Or does this not matter any more?

https://technet.microsoft.com/en-us/...(v=ws.10).aspx

"Because NTFS uses different cluster sizes depending on the size of the volume, each file system has a maximum number of clusters it can support. The smaller the cluster size, the more efficiently a disk potentially stores information because unused space within a cluster cannot be used by other files."

++ Second, I thought that by having separate partitions, I might protect myself somewhat from some potential problems - for example, if I accidentally caused a problem to one partition (for instance something where I would need to reformat), I might be able to avoid having to reformat the entire drive. Since I have accidentally managed to cause myself a problem or two here and there it seemed a reasonable precaution. Does this sound reasonable, or am I just being overly cautious?

- I like the idea of adding Diskpart Clean as my first step - better to be sure I've gotten rid of any corrupt code or fragments or whatever, right?
