Data loss on partitioning

Hi
I hope I've posted in the right place, otherwise please advise.
Following bad advice from an 'expert' on a YouTube tutorial who's declined to respond, I made a grave error by adding a (233Gb) partition to a (465.8Gb) WD external drive, which seems to have erased the data (45Gb) already on it. I'm surprised this happened so easily (wouldn't I be), since there was plenty of room for a new partition. Having created the extra partition, both now mount as volumes but there seems to be nothing on the original, single volume. As I understand it, Disk Utility will partition a drive without risk to existing data in most cases provided there's room, so why is it hit and miss?
I've looked at the possibility of re-writing the original partition tree using TestDisk and pdisk through Terminal but since the original partition isn't lost per se, I'm not sure how to work it. I'm now looking at any possible option to retrieving the original volume intact, rather than days of trawling through scrambled files using recovery software. Can anyone advise? Part of me still believes there's a simple solution. Many thanks.

Yet I have done just that, in Snow Leopard using just Disk Utility. Did it three times, actually. Added one partiton to my internal drive, then two to my external drive, then one more to the internal drive. All with no loss of data or bootability.
The trick seems to be to use the "+" button to do it, rather than the drop menu:
When I did it I was not sure it would preserve the existing data, so I made sure to create a fresh clone of the internal drive on the external drive before I gave it a shot. Worked fine, so I went ahead with additional partitioning.

Data loss Lacie 500GB external drive_ disk utility changed partition!

Details of problem. I have a 500GB Lacie mini hub HDD which is used with an iMac angle poise. Recently it has been playing up- unable to access folders/files etc. and since I know the PSU fails on these items (capacitors fail -5V and 12V go haywire- already fixed another one - I have a 320GB with a mac mini setup) I removed unit from the imac and connected in place of the 320GB lacie on the mac mini, using the known good PSU. The iMac is running latest 10.4 and mac mini is running latest snow leopard 10.6.1
The Lacie spun up and mounted OK and I was able to access all files folders with no issue, so since I was keen to make sure it was 'fixed' I ran disk utility. It ran and said it verified and then I realised I hadn't run repair so re-did this. Big mistake!
It did the same run and said no problems found, but it then said something like updating partition! Horrified I waited and it seemed to finish or had finished straight away. Not sure. I looked at folders and yes main 2 items in place, but nothing showing below this. ****. It got worse. I ejected and tried to reconnect and low and behold it says drive needs formatting now. Disk utility even shows this 500GB as having 2.2TB of space, which I see in other posts is another issue.
I have important data backed up elsewhere, but there are a large number of files I do not have copies of and suspect there is a way to recover these. I have since seen all the 'data loss' guest account issues and wonder if this is yet another bug in snow leopard.
Have tried running Techtool Pro 5.0.6 to see if it can see the data but its not seeing anything. Will try Diskwarrior and others, but may well shelve to see if apple gets an os update released for data loss issues.
Any thoughts on how to recover? Anyone with a similar issue? I am pretty certain this is not a failed hard drive as it sounds 100% normal. Thanks for any help or guidance.

Thanks for all the comments recieved. V.K. made me re-evaluate what I had proved or not. I was fairly certain (not 100%) that the drive mech was OK, because the psu had failed, but should have proved drive mech was actually OK. So I removed the mech (as USB abd firewire can't do SMART etc.) and hooked up to an old G4 Powermac. I then found that the SMART verified, but had forgotten the 128GB limitation on older macs. So removed and got a PC to hook it up and run latest IBM_Hitachi drive fitness and other diags. (its a Deskstar HD and I have had almost zero issue with these drives over the years.) It checks out fine, so I was correct in my initial thoughts, only the PSU was faulty.
So back to my initial suspicions that Snow Leopard or disk utility has screwed things up, maybe a bug, maybe not. And I did run verify first and it said it was OK, only when I re-ran the repair did it then do a "partition update" (or whatever it said - should have done a screen capture - searched apple but can't find listing of all mesgs avail. must be in developers site I expect). So I am back at looking at how to recover, if at all possible, but as Alsoft have said this is not something Diskwarrior can do directly. Files must still be there just partiton map is now in a ... needs to be initialised mode. Not that I will do that.
So I guess summary is possible bug/funny in 10.6 and/or disk utility.
sounds like I will be contacting Alsoft now
may read up on partition map damage first, so I get a better picture of whats involved.
Cheers and thanks for all the help/ideas.
BTW - been using macs_pcs for decades now and helping friends & family fix things as and when. This is first time needed to post on forum as always found answers to questions I had previously. Must remember the old adage of not jumping onto new technology until it has bedded down I bet if I had hooked up to the old G4 Powermac I wouldn't be in this position. Thanks again.

Recovery options for Mavericks MyBook/EFI data loss

Has anyone managed to recover full directory structures for the following data loss scenario?
OSX Mavericks 10.9
Any external drive initialised to a single MyBook partition with exposed EFI partition
WD Drive Manager / RAID Manager installed

If your data loss meets the above criteria then please:
open a support case with Western Digital
open a support case with Apple
If you are an Apple developer then please submit a defect report to Apple.
More reported cases = more attention by both Western Digital and Apple.
Please report your data loss on these forums, the WD community forums and here with the following information:
mac model / description
external drive(s) model, capacity, connection, paritions, empty name
eg MacBookPro9,1 (mid 2012 MacBook Pro Retina) and WD MyBook Studio II 6GB connected via Thunderbolt with 2 partitions reappeared as single empty MyBook and exposed EFI partition
You can find your mac model number using Apple menu > About This Mac > More Info... button under Hardware Overview: Model Identifier.

Convert Dynamic Disk to Basic Disk Witout Data Loss

I think I goofed somewhere and am in need of some advice.
This Windows 8.1 home server had two identical 160GB drives that at one point were mirrored. One of the drives failed but so I added a larger replacement hard drive (Disk 0 = 160GB, Disk 1 = 250GB) and was able to recover. However now, not only
is the mirror broken, but the configuration is crazy:
Disk 0 contains 1 100MB System Reserved Parttion (System)
Disk 1 contains 1 120GB partition where the OS is installed (Boot, Page File, Crash Dump)
Since its much quicker to move 100MB vs 120GB, I was thinking I'd copy the 'System Reserved' partition on Disk 0 to Disk 1 using a third-party utility, but because both disks are Dynamic Disks, this isn't possible.
So at this point I can only think of two options:
Recreate the 'System Reserved' partition on Disk 1 (Is it as easy as running bootrec /scanos or /rebuildbcd or /fixmbr or /fixboot?) > Wipe Disk 0 > Confirm Windows 8.1 boots > Then create a new mirrored volume on Disk 0
Mirror Partition 1 (120GB) on Disk 1 (where Windows is installed) to the available space (149GB) on Disk 0 > Break the mirror > Wipe Disk 0 > Confirm Windows 8.1 boots (maybe I'll need to run bootrec with some switch here?) > Then create a new
mirrored volume on Disk 1
Thoughts?

How to Convert Dynamic Disk to Basic Disk without Data Loss?

Thanks for the reply.
I've seen that post, among others, and they all require buying an application. None of the product pages, like the one you linked indicate that a purchase is required. It wasn't until I downloaded the aplications, (and I've tried several) that
I discovered a purchase was required. Really disappointed they weren't upfront about that on the guides.
So maybe a different approach can be taken:
Disk 1 just contains the System Recovery partition - the rest of the disk is blank (not partitioned)
Create a new partition
Copy the OS data from Disk 2 to Disk 1
Update the System Recovery and/or the Boot Configuration Data file to point to the OS that's now on Disk 1
Once updated, reboot
The system should boot properly from Disk 1 and the OS should also be running from Disk 1
Convert Disk 2 to a basic disk
Once Disk 2 has been converted back to a basic disk, can I just do the opposite?
Create 2 partitions on Disk 2: one for System recovery and another for OS
Copy the System Recovery partition (partition on Disk 1) to partition 1 of Disk 2
Copy the OS partition (partition 2 on Disk 1) to partition 2 of Disk 2
Update the System Recovery and/or the Boot Configuration Data file to point to the OS that's now on Disk 2
Once updated, reboot, the system should boot properly from Disk 2 and the OS should also be running from Disk 2
Convert Disk 1 to a basic disk
This is bonkers, believe me, but I feel silly shelling out $40-$50 for a single feature of an application. If I were going to use it regularly, or even periodically, I would do it.
I'm not very comfortable with bcdedit and bootrec so I need a little help with steps 4 in both sections.

One of my partition is not mounted. I can't mount it, can't repair it. I have a lot of data in this partition. I can't erase it, how can I do now? pls help me.

No way around this. Your phone has to be restored using a computer running iTunes. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

There is no data in the partitioned tablespace?

I am creating a new partition table like this:
create table PART_TABLE

tablespace PART_MOHAN,
partition par_new2 values less than
(to_date('01-JAN-2010','DD-MON-YYYY'))
tablespace PART_MOHAN2
Now,there is no data in the Partitioned table.
Now, i am inserting rows into the table.
But, rows are inserting into the table not in the partition tablespaces.
I checked the used space and free space of tablespaces, there is no change in size after inserting the row also.
But, when i check the table, rows have inserted into the table.
But, i dont know , in which tablespace these data are stored. How to find out that?

Selecting data from Multiple Partitions in a single select stmt.

Hi all,
My Database is very large & my tables are partitioned.
My question is:
1) If my data is spread across multiple partitions, is there any way to select data from multiple partitions in a single query?
If we dont mention partition name also it works fine, but perofmance wise it will be very slow. (Using EXPLAIN PLAN)
(Note:I dont want to make use of Union concept, i want to do it in a single select statement)
For ex:
qry1.sql:
select empno from emp_trans partition (P012000)
This above query(qry1.sql) will work fine.
qry2.sql:
select empno from emp_trans partition (P012000,P022000)
The above query(qry2.sql) will return will return the following error:
ORA-00933: SQL command not properly ended
If anybody has any solution for this, pls mail me immediately.
Thanks in advance
bye
null

All my queries are dynamically generated. All my tables are also indexed partition wise based on date field. My question is, if i want to mention multiple partition names at the time of generating my query(select), then with parformance will be good. I have refered some books, inthat what they say is to use UNION concept, i dont want to use that, instead i want in a single select statement.
Thaks for ur reply

There is no Data Loss!

Basically, any Pages file that has been modified and seemingly "overwritten" can be easily restored to its pre-5.0 state within Pages 5 by clicking File > Revert to > Browse All Versions and then selecting the previous version, clicking Restore and then closing Pages 5.0 without saving. That allows you to open the file in Pages '09 and delete Pages 5. Now everything is back to normal and you can continue using '09 until the feature set is restored.
I'm hoping people will continue to explore and verify this, but I've tried it myself and a few others have verified its validity. I started a thread yesterday but it quickly got buried in the swathes of complaints.

Great! Hopefully this means everyone can get back to their old files and continue working in '09 until the feature set is restored to 5.0. Now we can all stop clamoring about Apple intentionally damaging users' work. I was 1000% sure that wasn't the case. After "Save As" was depricated, Autosave and Version History are part of a normal workflow (except for those who rejected the whole idea of auto save - but Apple didn't), which explains why files were not explicitly duplicated with the upgrade and no warning was issued.
Does this work for you, Peter? If so I hope you can see the value of actually using the product before jumping on the bashing bandwagon.

Seems to work - I've unplugged the external disk as well as turning off Time Machine. Old versions are there, and not only that, when the restored file is loaded into 5, it looks the same as it did in 4.3., whereas if just the latest one is opened, layout is, er, not right.
The "unrestored" file has layout errors, whereas, the "restored" one still looks OK when reopened, even after making a few changes. This might not be the case if a "removed" feature has been used, such as linked text boxes - they are there but not linked.
You will not be able to open this file in 4.3 if you make changes, as robogobo also said.
So, are the earlier versions inside the new one? Word docs have all sorts of old stuff inside if you open them in BBEdit, especially if the author has used an earlier letter to someone else as a template, and altered the text. Having looked at a 4.3 xml file there isn't any changed/deleted text or other obvious stored changes. So they must be somewhere else, I suppose.
The 5 files are zipped .iwa, and I haven't found anything that the system will allow to open them (unidentified developer).

Could someone please verify this? Basically it would mean the transition from 4.3 to 5 is at least non destructive and we're dealing with a loss of features here but no data loss.

Browse All Versions:
Now I hadn't tried this before, but it was on my todo list. When I first noticed problems with files opened in Pages 5.0, I was simply restoring files from Time Machine in order to get back to the original version for 4.3, thinking it was necessary for version history. But correct me if I'm wrong, Time Machine isn't necessary for browsing documents version history. Is that right? I just tested it and it seems to work with my Time Machine disk disconnected. Can someone verify this?
I just opened an old 4.3 document in 5.0, made some changes, saved and closed it. Then I tried to open it in 4.3 and of course it wouldnt open. So I opened it again in 5.0, went to File > Revert to > Browse All Versions and it opened up the interface, which looks like Time Machine (I always assumed it was) but I think it's not. Anyway, I went back to the old version, hit restore and then closed it without saving. I can now open it again in 4.3 in its original state!
Did everyone already know this? If it's true, then there isn't any permanent damage being done, and everything can be reverted to originals from within5.0. I think this is great news.

If you upgraded directly from Snow Leopard to Mavericks, and never had Versions in Pages 4, can you still revert to the oldest version in Pges 5 and get a Pages 4 document?
The documents brough into Mavericks from Snow Leopard should still be considered the original versions before they're opened in Pages 5, so I think it would work. Probably best to open them in 4.3 on Mavericks first though, to be safe.
At any rate, data loss is only a problem if you have opened the only copy of a document with a new, untried application, and in that case, you are acting as though it isn't a very important document, anyway.
Couldn't agree more.

[DATA LOSS] I closed the Tab Groups and all my tabs dissapeared. How can I recover the tabs in Firefox 26? Would you please just delete this feature?

Thank-you in advance for reading all of this.
A slip of the mouse in trying to return to the left-most tab caused the tab groups feature to take over the window. I completely failed to comprehend what I was looking at and closed the thing by clicking the x because I damn sure didn't want what I was looking at. Undo close group? Of course not, I didn't want a group in the first place. Hey! My tabs are completely gone now! So in just a few steps all of which seemed innocent, I have lost all but ten of the tabs that were open, and those were only the most recent ten (and actually older tabs would have been more valueable than newer so insult on top of injury).
I don't think increasing the number of undoable tab closures is the answer. I think getting rid of the tab groups feature all together is the best way to go. I seem to have lost all the tabs I had open, irretrievably, and some of them had been open for WEEKS so they can't be reopened from history.
The tab groups feature is a data loss bug. Please remove it from the UX completely. If you have to figure out a way to grandfather people who actually have a tab group, fine but don't further vex me with it, please.
The reason this catastrophe has occurred is that your feature, was so discoverable that I activated it by mistake, and the UI after that had to be learned on the spot, yet was too complicated to learn. You really should withdraw it until you can figure out how to keep the UI for it from causing data loss such as I have experienced this morning.
Also, there may be other questions on this feature which are from a certain point of view the same as this one. It's hard for me to tell for sure. None of them had a true resolution so that's why I posted this one, also I'm seeking a specific fix, removal of the offending feature.
Why remove the feature? Because if I allow in my discussion the possibility of retaining it, it will stick around in its present and dangerous form until your team is done bikeshedding the new form it should take. Instead I want you to delete the feature and then require its champion to convince you that a new incarnation won't cause data loss before you allow it back in.
Fellow users, if you know of a way to recover all 50 lost tabs from an "undo close tab group incident", I would be grateful for that advice, but I would still believe the feature should be deleted. Some of the tabs have been retained for months so digging them out of the history is not practical.

I am not 100% certain but I am fairly sure development of this tab feature has ceased and it is likely to be deprecated. I am even less sure what the replacement will be.
Thus forum is not the place for discussing development issues or feature requests. (Developers do not use this site)
*You could comment using feedback <br /> https://input.mozilla.org/en-US/feedback
*Or try to find a developers forum or mailing list <br /> http://www.mozilla.org/about/forums/#general-development
I have not tried this and am not even using Windows at present but the tabs groups are stored as entries in the sessionstore.js files. Firefox has such a file plus sometimes numbered copies and a backup copy. Firefox will have re-writen these files but I suppose there is a posibility the Windows OS may have kept copies.
* see http://windows.microsoft.com/en-US/windows7/Previous-versions-of-files-frequently-asked-questions
* http://kb.mozillazine.org/Sessionstore.js Note the files are kept within the Firefox Profile
** Firefox Button -> Help -> Troubleshooting [open profile] (or some thing similar) is one method of locating the profile.
Find and backup any current sessionstore.js file. Consider also bookmark or otherwise recording anything you have open. Now find any previous versions and try putting them in Firefox's profile before restarting it.

Data loss popup for cancel button on overview page

Hi Experts,
Data loss popup generally appears on UI, when i try to navigate with out saving the changes. This is a standard SAP behaviour.
But, i come across the requirement where this data loss popup should also appear on clicking the 'Cancel' button on overview page on UI.
I understood that, this popup will be triggered by the methods ON_BEFORE_WA_CONTENT_CHANGE & IF_BSP_WD_EVENT_HANDLER~HANDLE_EVENT of the window impl class.
Please suggest how can i make this popup work in case of Cancel button as well.
Thanks....

Hi bkvs,
Usually when you click the "Cancel" button that means you don't want to save your entry... hence displaying the dataloss popup doesn't make really sense to me. However, you may want the user to confirm that he really wants to cancel.
So I would suggest to redefine the EH_ON_CANCEL method of your view, to display a simple confirmation popup before you actually cancel everything. This wiki will show you how to do it:

Updating to ios 6.1.5 leads to data loss in several apps (bento, teacher tool)

After updating to ios 6.1.5 I have experienced severe data loss in several apps. Can I return to older version of ios to rescue data?

All you can do is restore from backup
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

Booting Windows 8.1, blinking underscore problem - with data already on partition.

So I updated my OS X software from the App Store (just a newer version of Yosemite than before) not too long ago. I wanted to boot into windows because I had certain data and applications on there I needed that have no version for Mac. So I tried booting, but when I boot the windows partition, nothing goes beyond the blinking underscore. I tried researching the problem; people have had the issue with the blinking underscore, but that is when they tried installing windows [there was no data on the line]. I however installed windows quite a while back and it is stacked with data that is pretty important for me. If there was a way for me to transfer the data to an external drive or the Mac partition as backup, I'd gladly just re-install windows. But there's data, I need the data on that partition. I know it's 100% possible to get the data, but I'm not sure anyone has found a way yet[?]. I've seen solutions that require things like gdisk, but the problem where that stuff would be required is a little different from mine; their partition wouldn't show as being bootable at all, so I didn't try that method (I'm just being cautious, Macs aren't my specialty ) However, in Disk Utility, the partition is labeled as disk0s4, which is similar to those other problems people have had in the past. If possible, can somebody point me in the right direction, or maybe even walk me through it? I'd greatly appreciate it. And if my problem does get solved, can someone suggest a safe way of updating OS X without it corrupting my data on other partitions?

Well the only update other than Yosemite would be Autodesk Sketchbook from the app store, but I doubt that it would have to do with bootcamp, so no, there were no updates other than a new version of Yosemite. And have testdisk, but do I need to search for lost partitions? That's an option I can see here. If I need to look specifically for NTFS headers, then maybe I'd needs steps on how to do that.
EDIT: I started running the process to look for lost partitions, and these are the first things that came up:
0 D HPFS - NTFS           2292342621 2292363587      20967

Stop
Is this what TestDisk is supposed to be trying to find anyways?
EDIT 2: It stopped and showed me this message. My total hard drive space is 750 GB including all partitions. I honestly have no Idea why the 4000 and 3000 GB are showing up
Disk /dev/disk0 - 750 GB / 698 GiB - 1465149168 sectors (RO)
The harddisk (750 GB / 698 GiB) seems too small! (< 4144 GB / 3860 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:
     Partition               Start        End    Size in sectors
