Where is my 30GB partition?

Hi
I've got mac book pro and I had windows XP on one partition which was 30GB.
I went on Disk Utility and delete the partition as I don't use windows no more and I was hoping to add that 30 GB to my MAC partition! but It just disappear and I can't find it! I took a screen shot:
http://img.skitch.com/20080310-rx31q9hrxyy46tjmg8sdihmkjt.jpg
and there is 200 MB partition in there where I have no idea where did that came from?
and If you look at the screen shot my MAC drive is only 116GB right now!!!
Please help!
Thanks

it may be that your earlier attempts to get rid of Windows / the bootcamp partition have meant that the utility can't recognise it, I guess.
Next thing I'd try would be choosing the "First Aid" tab in Disk Utility, selecting "149.1 Fujitsu MHW2" in the left hand pane, and then running "Repair Disk" , followed by "Repair permissions".
If this doesn't work, the only option may be to back-up the Apple partition to an external drive, reformat the drive, and then restore from the backup, I'm afraid.
Cheers and good luck

Where has my NTFS Partition gone in Windows 8.1? Shows in Mavericks fine!

I have set up a new external HDD (USB 3.0) to use on my mac with 3 partitions a Mac Journeled Partition, a FAT32 partition, and an NTFS partition. I set up the portioning in Disk utility and set it to use a GUID partition table. Initially the NTFS partition was created as a FAT32 partition, then reformatted to NTFS through Windows 8.1 This all worked fine until I installed a version of Mac Os X to an External HDD so I can dual boot a test configuration.
Now when I'm in Bootcamped Windows 8.1 the HFS partition and the FAT32 Partition show but not the NTFS one. Looking in Computer Management it shows 2 unallocated partitions where the NTFS one should be. However, when I go into Mac Os x (either installed version the partition is there, and fully readable! I'm very confused as to why Windows can't read the partition! I'd like to try and fix it without losing data or having to reinstall the Mac OS Installation if possible.
Has anyone encountered this before?
Many thanks,
John

Hello and Thanks MeipoXu, Well it's to late! I got frustrated after searching windows and microsoft websites and forums, so, I chatted with a damg geek squad "agent" and he talked me into doing what I knew I could do four hours before I got them
and had him do a remote assistance. Well to make a long story short we faut for a while and he led me to believe there was no other way except to reformat the drive and loose all of my files! I got ahold of them thinking they would have a solutiion to the
problem not reformat and loose everything! I'm very upset with the geek idiots and I've left terrible feedback as I do every time I talk with those idiots. All may not be lost though, I also have a WD MyCloud 3TB network drive and I'm hoping and praying that
most if not all of my files are on it. I sure wish I'd have waited till I got an answer here before I contacted the geeks. I don't know anything about powershell at all, but, lately I've been trying to learn some of the commands and what you can do with it,
and it seems like it would be very useful and I hope I can learn it. It seems very complicated right now and I don't understand it all, I even tried some commands I found on the forum to try to dislodge my drive from the storage space and pool and they did
not work. I typed the command word for word I don't know what I did wrong. I sure want to learn it though it would save me a lot of headaches. Thank you very much for the reply though I just wish I'f have waited to hear from someone on the forum before I contacted
the geeks. Thanks again! Turbo930.

Where does my win7 partition go?

Hello all,
I've used my MBP since 2011, I use auch both win7 and mac OS.
I've my snowleopard upgrated to OS X 10.9.1 later. The both systems work good.
Last week i tried to upgrade my win7 OS, because this one is not actived since it has been installed.
The system needs to restart, then i restart the machine. That's the time i got the problem.
Whenn the OS restarts, i press the option key to switch to Win7, but I got just EFI boot. After choosing the item, the screen stay for 30 minute with a symbel, it's indicates that the OS works failed, then the machine is power off.
I'm using the driversutilities under Mac OS to check the information of my drivers, find out that the size of the driver is right(320GB), but the partition(60GB) for win7 is totally gone. which means the partiton is invisable right now for Mac OS..
Can anybody tell me, what's going on here? How can I find back my losting Win7 partition or how can I find the driverspace of Win7.
Any inputs will be appreciated!
Jian

Jian,
in the Finder, press Command-Shift-U to bring up the Utilities folder; run Terminal there. In the Terminal window, give it the following commands, one per line, ending each line by pressing the Return key:
diskutil list
diskutil cs list
mount
Please include in your reply the full output from these commands.

Where did my 30GB go? (Space cluttering) [SOLVED]

I use a very clean install with Openbox as window-manager, and no big KDE(libs) or GNOME depending programs, only the small ones depending on innocent qt or gtk libs.
I have a 36GB Raptor 10.000RPM harddrive, which I use as my primary system drive, and this is where ArchLinux is installed.. I think when I installed ArchLinux first it was only taking up 2-4GB in total, I only installed base..
Anyways!
[dezza@dezza /]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 34G 28G 6,0G 83% /
none 1013M 0 1013M 0% /dev/shm
/dev/sda3 46M 12M 32M 28% /boot
I can't see why I should use 28GB of my 36GB harddisk, this simply can't be packages from applications and etc. from pacman cluttering all this space up ..
This is all my installed packages, very clean..

Crashed during partitioning - lost 30GB of space??

Hello all,
I was installing Bootcamp for the first time on my main internal HD. I set Windows to be a 30GB partition. During the partitioning I got the dimmed screen of death that told me to hold the power key down to restart. It restarted fine (thank you!) but I lost 30GB of HD space. When I went back to the BC assistant it didn't see a Windows partition. I'm worried that if I try again I may loose another 30GB of space. Is there a way for me to get that 30GB of space back before I try again? Obviously, if I can do this without a complete re-format and re-installation of every piece of software that would be the better way for me.
Thanks!
Jeff
MacPro 2.66 / 10.5.2 / 4GB ram / 250GB internal HD / ATIX1900

Thanks again, Axel.
I might try that, but I need to get a new external HD anyway, so I just might wait until I get it and just install Bootcamp/Windows on that HD. If that doesn't work I might try to go back any fix the fragmentation on the internal HD. It would be nice if the disk utility had a defrag on it though. I would think that would be something apple would have added to it by now.

Clone a Mac Partition to an External Drive from within Windows 7 Bootcamp?

Anyone know if it is possible to clone the mac os x partition to an external drive from within Windows 7 bootcamp? I (like a few others) had a problem with the latest 10.6.3 update and I cannot boot into the mac partition but I can access it via bootcamp so I was thinking about trying to clone it to an external drive and then boot from the new clone and see if that works.
Appreciate your comments.

setup a 30GB partition on an external drive, along with a partition of 150% the size of your Mac OS X volume -- or larger.
Install OS X to 30GB.
While booted from DVD, before you install, you'll need to go to Utility Menu => Disk Utility to do the partitoning. While there, in DU see if you can repair your system.
And where is your TimeMachine or clone backup? The "Step #1: Backup before beginning your Boot Camp project."?
No way to backup or clone from within Windows, though you may be able to write to NTFS backup volume, UNLESS you bought MacDrive8 which allows read AND write to HFS+ from within Windows.

Can I move my operating system to a different partition on the same drive?

I thought I knew what I was doing when I partitioned my hard drive and installed the operating system and everything else. The other partitions are for documents, photos, etc. It worked well for quite a while but now I find there is not enough free space on my start-up partition (24GB) to be able to do new installations. I have cleared a 50 GB partition on the same drive to be the new home of my operating system. I tried copying all the files in the System partition to the new drive but "Startup Disk" doesn't recognize the copied version. How can I make this work without having to install everything all over again?

Too true. I have been partitioning my drives since the 80's when it was "illegal" and voided warranties as was opening the case on a Mac. Now the cases open right up and you drop and slide in new drives and memory. And it has saved my butt many many many times. You put your operating system on one partition, from what I have read it is best on the first partition of the first hard drive in the chain, Master, if you have more than one drive. I have four drives with now down to 8 partitions with the last two 10.4.x OS's that worked well and my last 10.5 for emergency use, all on one drive in separate partitions and boot to them all the time with no problems. I always keep my last install just in case intact and bootable. It's no different than what is done with BootCamp and running Windows. Then put all your data, files, non-Apple applications on another partition(s). That way when the OS hammers, and it will, all you have to recover is the OS and your data is safe. Thenall you really have to worry about is certain preferences and databases that have to be on the start up partition that won't work when aliased. I have found them, and they are few, and use Backup from the iDisk software library to back these files up to my iDisk nightly. And having the OS all by itself makes back ups so much easier and smaller. But you have to leave Apple applications on the OS partition in the Applications or Utilities folder or the Apple Updater will not see them.
Before iTunes and iPhoto would allow you to link to databases that are not on the start up partition, I was aliasing those files from other partitions. Then early 10.5 it didn't work as well, now when you hold the option key prior to starting up in iTunes and iPhoto you'll get a window to go find or create any of many databases to run off of. I have done this for years with Apple, Microsoft, Macromedia, Adobe and many other applications.
So far my largest OS has been 14.6GB after I installed GarageBand and it loaded a ton of instruments on to the OS partition. I have been through this before and found them and moved them off to another partition and aliased them back and GB works great. Otherwise, even in 10.5.x you can have relatively smaller partitions. And yes you want room to grow, if even just scratch disc space that some applications will not let you choose or go off the OS partition. So I hover around 25-30GB partitions and have never gotten close to getting more that 60% full, fulfilling the 10-15% free space axiom that seems to get larger with every update. I have read here that several people that had taken their machines to an Apple where they replaced drives saying that the techs partitioned the drives and said that the minimum for 10.5.x was 12GB. As the updates flow, that will vary probably up. Plus Apple has some bloated applications and a ton of things that you'll never need or use that take up room that are a pain to find, like unnecessary fonts. A little extra space is always good.
I use CarbonCopyCloner to make compressed back ups and bootable clones. The older versions would not copy files that would be easily rebuilt when you booted that OS, thus cleaning up the clone/back up by cleaning/omitting files that normally get damaged. Not sure if that is part of the latest versions. I think they copy everything. Another great thing is that Apple installers and Disk Utility and can use them to restore or migrate from. Because of CCC, I now have it down to 10-15 to restore a crashed or failing OS from parts. I have yet to loose anything, except time in having to deal with an OS that sometimes has a mind of its own.
As you play around as I did when I was waiting for an Apple Tech Rep, and reran the Combo Updater back over a wonky install, to find out if you could do that, it was done and worked great just as he returned and said no one there knew. I told him that I did and it worked great. We kept in touch for a couple of months to see if anything weird happened, which it didn't, and now it is suggested and common practice. Just as the Tech's and I whispered under our breath in the 90's about partitioning. Now they suggest it and Apple will talk to those that have partitioned. As you see needs and experiment you'll learn (trial by fire) and all this will become second nature. So don't think this is too much and go for it. Just make sure before you are completely comfortable, have another drive, I use 25GB Rewritable Blu-ray Discs, to do regular normal, CCC, back ups until you get the hang of it. This method yields 6-8GB compressed archives. Then you'll have a place for your stored back ups and whatnot. I was keeping up to 5 iterations, i.e.: 10.5.1a, b, c, d and e. Once my paranoia subsided I pared it down to two since I could easily recover the small amount that I have to now from small back ups that are mostly aliases relinking files that are safe on other partitions.
So yes you can put/clone the OS to another partition. Just make sure you cover your bases, use an application made for cloning/backing up (CCC) and label your installs as not to have the same name on two OS's or you'll have a bit of a problem off the top remembering which is which. I'm on 10.5.5C2.
Good Luck and Happy Partitioning.

Installing Boot Camp - There is only one partition available for Windows

I have a brand new Mac Mini. Ran Boot Camp assistant and created Windows partition - 80 GB. Then when instructed, inserted Windows XP install disc. It went through some install steps then came to screen where you chose the partition to install Windows. There was only one partition showing - Partition 1. I think that's the Mac partition, so I quit install, removed partition with Boot Camp and tried again, this time setting Windows partition at 32GB. Insert Windows install disc, same result - only Partition 1. I called Apple support, we did it all again - same result. They had me completely reformat my Mac disc with the OSX discs, then run Boot Camp assistant and set partition to 32 GB. Same result - only Partition 1 is available. The Windows install disc I am using is the same disc I used to put Windows on my son's MacBook about 9 months ago.
I need this Mac Mini to run both OS. What to do?

Use NTFS for Windows and buy Paragon NTFS for OS X
You can also try Paragon HFS for Windows
As long as you are using for data and backups, you can leave the drive as GPT too.
I would recommend strongly to always have a 2nd bootable Mac OS drive, only need 30GB partition. System maintenance. Though LIon Recovery Mode finally makes it less but not totally unneeded.
And yes you can use Windows to create a partition.
Boot Camp is too broad. Do you want or mean BC Assistant? not needed but probably possible.
MBR has trouble with 3TB drives.

Please help restore DMG missing partition and access file vault.

I am quite emotional at the moment, if anyone can help me access my files, pictures of my baby daughter and important documents.. I would be extremely grateful and willing do make a donation via paypal.
I have a 160 GB hard drive, which was partitioned as 30GB Spare and 130GB with my operating system and user files, including my filevault user directory.
My computer was downloading movies which filled up the 130GB partition, most of the 130GB is contained in my personal filevault user directory, my computer became very slow and unresponsive and i tried to free up space by deleting files which i no longer needed.
The machine became slow and un-responsive and required a number of forceful shut downs and restarts until the machine would no longer boot up, I inserted the OSX CD and attempted to boot from CD and use disc utility which now only displays my 30GB storage space, I was forced to install OSX on the remaining 30GB partition.
Now running OSX on the 30GB partition i used DISK DRILL to scan my hard disk for the missing 130GB partition which it did and i was able to save this as a DMG file to a external hard disk, now i am able to get this DMG to mount in the OSX i am running on the spare 30GB space, however i am not able to access the majority of the data inside the file vaulted user account.
I would like to know, would it be possible to restore the missing partition, as it remains on the HD but seems to be hidden.
Or is there somehow i can login to the user account on the mounted DMG ?
I am not very familiar with using terminal and would be extremely grateful for any advice or support leading to the recovery of my files.

Is there anyway to recover the larger partition ? In disk utility i made the mistake of pressing the - button which has left me with the following:

And the grey space which contains my previous operating system and all my information which i desperately need to retrieve.
Is there anyway to restore and boot the missing partition ?
Probably not.    You've now deleted the partition. It was probably useless anyway, though.
When i run disk drill or other disk recovery tools i am able to see the partition including including the files and my personal sparsebundle.
But you can't open the sparse bundle, much less see any of the files inside it, right?
Since you've already recovered the (probably-damaged) sparse bundle containing your encrypted home folder, you'll have to work with it.
I'd strongly recommend making another copy of that on another external HD and putting that "on the shelf" before doing anything else to it.   I suspect you have little chance of recovery, but don't take the risk of further damage.
You haven't answered my earlier questions:
Have you tried to run Repair Disk on either the original or copied partition?
If that doesn't help, this might: http://www.thexlab.com/faqs/fixfilevault.html
Do you have Time Machine backups?
Obviously, now that the partition has been deleted, you can't run repair disk on it, but try it on the recovered disk image.
You need more expertise than either Christopher or I have. Since Apple no longer uses "legacy" File Vault, it will be more difficult for them to help, too.
Is your Mac covered by AppleCare? If so, give them a call.
If not, your nearest Apple Store Genius Bar might be able to help: http://www.apple.com/retail/geniusbar/
Or check for an Apple Authorized Service Provider: http://support.apple.com/kb/HT1434?viewlocale=en_US
If not, one of them may know of an outside service than can help. That will be quite expensive.

Windows 7 setup can't create or see partition

Hi all, I am trying to install Windows 7 x64 SP1 on my late 13 MBP. I used BC assistant to mount the iso on a 8gb usb. I have used two different iso files, one from digital river and one from torrents (its not a 'cracked' one or anything, I just couldn't find how to get one from Microsoft. This one is supposedly the same as the one from microsoft.) I plan to get a license key from my university once I make sure I can install it. Anyway, I can mount the iso and download bootcamp files using the assistant. I can make the partition using BC assistant as well, and I set aside 32gb for the Windows partition. After it partitions, it reboots into the Windows setup.
In windows setup, I pick windows 7 professional 64-bit from the list, hit next until I get to the part where you select the partition (of the four) on which to install Windows. When I select the BOOTCAMP one, there is the same little dialog text at the bottom as if I had selected a mac partition, saying that it can't install and the partition must be formatted or something. So I select the BOOTCAMP partition and press Format. When I press Next, a message appears saying that "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information."
I have also tried: unplugging all USB peripherals
using the right instead of left USB port
not formatting the drive and pressing 'next' only
deleting the bpptcamp partition from within windows setup and then forming a new partition and then formatting that
using both ISO images
selecting each of the four editions I can choose from (home, home premium, pro, and ultimate)
repairing/verifying the mac HD and permissions
Note that every time I re-attempt, I am forced to remove the windows partition and recreate the partition using BC assistant. In other words, if I quit windows setup and restart, hold down option, and select the windows USB to boot, a different windows setup starts up. It is similar but has slightly different screens than before, and after I press "install now" (a button absent from the first setup) an error message pops up saying that a CD/DVD driver is missing and I must locate it. When I try to locate the driver, which I would think would be in the bootcamp folder on the USB, it can't find the USB! Under My Computer all I see are the C: drive (inaccessible from here) and X:, which I think is the windows partition because it has some of the windows system files on it. I can't get past this stage of looking for a driver without completely removing the partition and then rebuilding the windows partition using BC assistant.
What do I do?
If it helps, in the mac os disk utility I can look at the Info for the windows partition, and in the properties it says "Owners Enabled: No, Can be Formatted: No, Bootable: No". Does that matter?
Thank you!

I don't have a hub, I will try a usb 2.0 though when I get a chance. Diskutil list gives:

Semantic Partitioning Delta issue while load data from DSO to Cube -BW 7.3

Hi All,
We have created the semantic partion with the help of BADI to perform Partitions. Everthing looks good,
first time i have loaded the data it is full update.
Second time i init the data load. I pulled the delta from DSO to Cube . DSO is standard where as Cube is partition with the help of semantic partition. What i can see is the records which are updated in Latest delta are shown into the report rest all are ignored by the system.
I tried compression but still it did not worked.
Can some has face this kind
Thanks

Yaseen & Soujanya,
It is very hard to guess the problem with the amount of information you have provided.
- What do you mean by cube is not being loaded? No records are extracted from DSO? Is the load completing with 0 records?
- How is data loaded from DSO to InfoCube? Full? Are you first loading to PSA or not?
- Is there data already in the InfoCube?
- Is there change log data for DSO or did someone delete all the PSA data?
Sincere there are so many reasons for the behavior you are witnessing, your best option is to approach your resident expert.
Good luck.

I recently deleted a partition on my mac that was intended to install windows. Now it is just blank space. I attempt to resize my Macintosh HD partition to cover entire hard drive space and hit apply but nothing happens (disk utility). Any ideas?

I have a few problems...
I wanted to make a partition to install windows, I tried to use bootcamp 5 where it wanted to partition and install windows at the same time. I do not have a cd of windows but instead had it on a flash drive. Bootcamp couldn't find it. Instead I was reading forums and found that there was another way to install windows by partioning your harddrive using the disk utility, downloading the bootcamp drivers, and installing rEFIt (an app that when starting the compouter a menu would come up to boot windows from the flashdrive). I try that and the windows install screen gets me to the point where I pick a partition. I attempt to pick the partitioned drive but a message comes up telling me that "this is of the GPT partition style" and windows cannot be installed on the drive.
So now I went back to disk utility and deleted the partition but there is still blank space. I wanted to retry and install windows through bootcamp (somehow) but a message comes up that there cannot be any partitions or that a partition must be created using bootcamp. SO i keep trying to drag the partition over the blank space and hit apply but nothing happens.
By the way I was trying to install windows 8 pro, some forums would say that you cant install win8 however I found others that said you could. How do I fix my partition and how do I use bootcamp to install windows (preferrably 8)?

Csound1 What Ive been trying to explain is that I have been running bootcamp, I open the app where the first screen is the introduction, i hit continue, the first time I select "download the latest windows support software fromm Apple" then I return and instead select "Install Windows 7." Then hit continue. The third screen is where I "Create a Partition for Windows" I set Windows to 80 gigs then hit INSTALL. As stated before Bootcamp cannot find the install drivers saying "The installer disc could not be found." My windows software is on a USB drive not a disc, I tried using a virtual disc reader to make it appear that the windows software was running on a disc, still no luck. What I would like to know is how to install windows on bootcamp.

Best way to set up partitions on 250GB external drive

Hi all,
I've decided to go with an Iomega eGo 250-GB FireWire portable drive to back up my iBook's hard disk (30 GB) plus to store my photos and maybe hold a bootable copy of OS9.
This is my first time using an external drive, so I don't really know how to go about setting things up.
What would be the best way to set up the partitions on the external drive?
1) I know I should create a 30GB partition for the iBook backup, but what about for the remaining volume? Is it best to leave it as a single large 200GB partition, or split it into two 100GB chunks? Other than the clone of my iBook, I'll mainly be storing photos (at the moment no more than around 10-12GB).
2) I don't yet have a huge iTunes collection, but if I later want to store iTunes music that doesn't fit on my internal drive, is it fine to put it in the same partition as the photos, or would it be preferable to create a separate partition?
3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
Thanks for any advice

The answer to both question is that it's completely up to you. Partitioning or not partitioning won't affect operation significantly.
3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
The iBook G4 can not boot from OS 9 so you would only be able to run OS 9 in the "classic" environment.
4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
No
5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
There are a few tools which promise the ability to change the partitioning without destroying the data on the drive. But you should never do this without making a backup of the data on the drive. Data loss can easily happen and in a big way.
6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
That is the best format.

Hard drive partitions not visible

I have a MacbookPro, with 3 partitions on the hard drive:
* boot disk+OS X (33GB, os x journalled)
* data partition (107GB, os x extended, case sensitive)
* spare (5.5gb, "Unix File System" which I believe is OSX's word for ext3)
Quite often, when I boot up, only the first partition is visible. Disk Utility shows the drive as having one 30GB partition, and the rest as unused space. This is particularly troubling for me, as my home directory is on the second partition, and when it is not found, I cannot log in.
What could possibly be causing the partitions not to be seen?
When this happens, all I can do is continually reboot, hard and soft, until magically one time it works. Sometimes, it also fixes itself after 5-10 minutes.
Any thoughts or ideas?
Thanks,
dave

No ideas anyone?

When table with clustered columnstore indexe is partitioned the performance degrades if data is located in multiple partitions

Hello,
Below I provide a complete code to re-produce the behavior I am observing. You could run it in tempdb or any other database, which is not important. The test query provided at the top of the script is pretty silly, but I have observed the same
performance degradation with about a dozen of various queries of different complexity, so this is just the simplest one I am using as an example here. Note that I also included approximate run times in the script comments (this is obviously based on what I
observed on my machine). Here are the steps with numbers corresponding to the numbers in the script:
1. Run script from #1 to #7. This will create the two test tables, populate them with records (40 mln. and 10 mln.) and build regular clustered indexes.
2. Run test query (at the top of the script). Here are the execution statistics:
Table 'Main'. Scan count 5, logical reads 151435, physical reads 0, read-ahead reads 4, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Txns'. Scan count 5, logical reads 74155, physical reads 0, read-ahead reads 7, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Workfile'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
SQL Server Execution Times:
   CPU time = 5514 ms,
elapsed time = 1389 ms.
3. Run script from #8 to #9. This will replace regular clustered indexes with columnstore clustered indexes.
4. Run test query (at the top of the script). Here are the execution statistics:
Table 'Txns'. Scan count 4, logical reads 44563, physical reads 0, read-ahead reads 37186, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Main'. Scan count 4, logical reads 54850, physical reads 2, read-ahead reads 96862, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Workfile'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
SQL Server Execution Times:
   CPU time = 828 ms,
elapsed time = 392 ms.
As you can see the query is clearly faster. Yay for columnstore indexes!.. But let's continue.
5. Run script from #10 to #12 (note that this might take some time to execute). This will move about 80% of the data in both tables to a different partition. You should be able to see the fact that the data has been moved when running Step #
11.
6. Run test query (at the top of the script). Here are the execution statistics:
Table 'Txns'. Scan count 4, logical reads 44563, physical reads 0, read-ahead reads 37186, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Main'. Scan count 4, logical reads 54817, physical reads 2, read-ahead reads 96862, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Workfile'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
SQL Server Execution Times:
   CPU time = 8172 ms,
elapsed time = 3119 ms.
And now look, the I/O stats look the same as before, but the performance is the slowest of all our tries!
I am not going to paste here execution plans or the detailed properties for each of the operators. They show up as expected -- column store index scan, parallel/partitioned = true, both estimated and actual number of rows is less than during the second
run (when all of the data resided on the same partition).
So the question is: why is it slower?
Thank you for any help!

Hello Michael,
I just simulated the situation and got the same results as in your description. However, I did one more test - I rebuilt the two columnstore indexes after the update (and test run). I got the following details:
Table 'Txns'. Scan count 8, logical reads 12922, physical reads 1, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Main'. Scan count 8, logical reads 57042, physical reads 1, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Workfile'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table 'Worktable'. Scan count 0, logical reads 0, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
SQL Server Execution Times:
CPU time = 251 ms, elapsed time = 128 ms.
As an explanation of the behavior - because of the UPDATE statement in CCI is executed as a DELETE and INSERT operation, you had all original row groups of the index with almost all data deleted and almost the same amount of new row groups with new data
(coming from the update). I suppose scanning the deleted bitmap caused the additional slowness at your end or something related with that "fragmentation".
