16gb micro SDHC on E90 - data loss

Hi there,
My 16gb Sandisk Micro SDHC which I was using on my Nokia E90 was alright till yesterday. This morning when I browse my memory card, I cant see any of my data on it. All I can see is the default folders "Documents, Images, Other, Sound clips & Video clips" which are empty, and few unrecognized files named with special characters on the root. The annoying thing is when I check the card details, it show 7gb as used space. I am able to put new data on it, tried copying a file from phone memory to memory card and it worked fine. Checked it on my PC too, shows the same contents as the phone do. Properties of the drive shows 7gb as used space, but the properties of the contents shows just around 50KB. Even nothing found in hidden mode.
What happened to my memory card? Will I be able to retrieve my data back?
Kindly share your ideas...
Many thanks...
sreegonu

....contd.....
For other purposes, 've installed FExplorer today on my phone and to my surprise, few of the disappeared contents are shown on FExplorer, and those contents which are explored on it are now appearing directly on phone's File Manager. But the other items are still not found and the storage still shows 7gb data is on it. And those files like things with special characters cannot be deleted. Even the options menu doesnt work for them.
please help...!

Optimum allocation size Toshiba Class 2 16GB Micro SDHC card

Hi --
Be gentle, please. I am newly registered here and am not sure that I found the correct forum to post this question.
I have a new Toshiba Class 2 16GB Micro SDHC card, just received today. Before I used it and while it is still under warranty, I wanted to test it for genuineness with the H2TestW program, which requires that I format it first.
Certainly I want to retain the default fat32 format but what file allocation size is best?
The card will mostly be used in my Sandisk Clip Plus to play MP3 files. A quick glance shows most of those files to be 5,500-10,000 KBs.
Suggestions, please?
Thanks.

Hi buddy,
I use different SD and SDHC cards for years now and I always use the default settings for allocation size. I never had any problems with that.

Toshiba 16gb micro SDHC card problem, please need help!

Hello,
I didnt know where to post about this problem, so I just post it here. I bought few months ago Toshiba 16gb micro SD HC card for my android Huawei Acend G300 it worked fine for two months, in computer and in my phone, but yesteday after I listened music my android made restart by itself. I tought it was nothing so I went to sleep. But in the morning I saw that my mobile says that I have no sd card insterted into phone. I made restart to my phone, took battery out and took sd card off and put those back in, but still didnt find my sd card. Then I put my sd card into computer with micro sd card adapter but it cant find my sd card too. it doesnt reconize it. Please does anyone can help me with that? I had important stuff on that card,
Thank You For Reading
PS! Sorry for my english I hope you understood what I was saying.

Greetings,
I realize it's been quite awhile since your post but, did you ever get a response on how to correct the issue with your 16GB MicroSD HC card that 'died' suddenly? I ask because I had a similar issue. My card suddenly unmounted itself (it was in a Galaxy S3) then it just was 'gone'. Phone doesn't see it, pc doesn't see it...
From what I was able to determine it would appear that this card is history and unrepairable but was curious if you ever had any luck in either recovering data and/or getting the card to be useable again.
thanks,

Does Nokia 3600 support Micro-SDHC memory?

I am afraid I cannot find the answer to this question anywhere on the web:
On the one hand, the manuals refer to Micro-SD. I called Nokia and I was told that the 3600 supports only Micro-SD and not Micro-SDHC. But the person didn't sound really sure.
On the other hand, I found several online retailers offering Micro-SDHC cards referring specifically to Nokia 3600. Also, some reputable memory manufacturers (e.g. Crucial) point to Micro-SDHC products when I identify my phone as a 3600.
Can anybody tell me who is right?

sometimes what nokia states is based on avaliablility of current size memory cards and nokia's testing with particular phones. so other cards may work just fine in phones that are not indicated but there is no guarantee as they were only tested with a certain limit and that limit is what nokia would post. it is recommended to use certain card sizes with certain phones for optimal performance as well especially lower end phones that do not have sometimes enough juice to sort through a huge quanitty of data.
You know what I love about you the most, the fact that you are not me ! In love with technology and all that it can offer. Join me in discovery....

WRT400N data loss

Have new WRT400N router and 2 laptops running Windows/XP SP3. Copied a 2.3GB folder of photos from PC A to PC B. Lost 152 photos on 1st attempt (wired); 3 photos on 2nd attempt (wired); 8 photos on 3rd attempt (wireless). Normally did 10-16GB machine-to-machine copies without a problem on old, now dead router.
When I copy the same folder to an external HDD or a memory stick, I lose no data. When I move the memory stick to PC B and copy onto the internal HDD, there is no loss of data. Anyone else having data loss problems with the WRT400N? Or have any ideas?

Thanks, via_fan. Have to admit that it took awhile to figure out that you wanted me to change router settings. Guess that's why the Linksys forum calls me a "Newbie".
I did try your recommendations, but still have the same problem. I have also made sure that the drivers for my 4 network adapters are the latest versions (one was a year out of date). Followed by another test run; still a few missing photos. Then I ran CHKDSK on both machines and tested again. Still missing photos. One lap top is on the road for a few days, so I have time to develp my next step.

Sandisk's 16gb micro sd card compatible?

Hi,
Here is the link of the item:
http://cgi.ebay.ca/Sandisk-16GB-Micro-SD-SDHC-MicroSD-Memory-Card-16-GB-TF_W0QQitemZ130314550455QQcm...
I want to know if this micro device is compatible with the BB curve 8900. It says on the box of the BB that it's compatible with micro sd and in its description that its compatible with a card up to 16gb of memory.
So... Yes or no? I'm not sure b/c the seller isn't sure, he just told me to check out with my manufacturer.

Hey,
Don't be upset with seller's comment!!
From your device go to Options -> About...you'll find your device's OS version. Now match that OS version with the below table -
BlackBerry Device Software version
Media card size limit
BlackBerry Device Software 4.2.0
Up to 2 GB
BlackBerry Device Software 4.2.1
Up to 4 GB
BlackBerry Device Software 4.2.2
Up to 4 GB
BlackBerry Device Software 4.3.0

BlackBerry Device Software 4.5.0
Up to 8 GB
BlackBerry Device Software 4.5.0.81 and later
Up to 16 GB
BlackBerry Device Software 4.6.0 and later
Up to 32 GB
By the way all 8900 devices hit the market with OS version 4.6.0 and above....meaning your device will accept media card upto 32GB.

16gb Micro SD For E51??

G'day,
Could somebody please enlighten me as to weather my E51 will support a 16gb micro sd? I've googled, come up with mixed results/answers and would like to know for certain before buying one?
Cheers.

If it takes 4GB, it will take anything up to 16GB. Check here: http://europe.nokia.com/find-products/accessories/all-accessories/memory-cards-and-cables/memory-car...
Although the site does not say the 32GB is compatible with the E51 - or my E90 - I think that both should accept that card easily as well.

How Long will it take to reset the 16gb ipad with clear all data in it.

I have the same problem. I try to reset my ipad / iphone 3g using the reset and delete all content on general. It is almost 2 days now but my ipad / iphone 3g are not yet finish. Only apple logo / looping circle appears on the screen. What will i do? thanks... iOS 5.0.1

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.
robogobo wrote:
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.
Karabuni wrote:
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).
robogobo wrote:
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.
robogobo wrote:
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

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.

What can I do simply to keep all my previous contents, (own pics, videos, etc.) on my previously authorized iPad on PC, but get a new authorisation and a right syncronization, without data loss with a new iTunes on my new Mac?

Friends,
I already had an iPad(1) and its full contents (not only the purchased items, applications from Apple, but my all own pics, videos, songs etc.) is normally syncronized with an authorized PC (Windows) computer.
Now, I've bought a new MacBook Air computer, and want to sell my PC. But I don't know how to transfer (or syncronize) all of the contents from my previous iTunes on PC to the new one on the Mac.
When I connected my iPad to my new MacBook Air, I promted, if I want to change authorization of my iPad to the MacBook.
But also got a warning, that the new iTunes will delete from my iPad all my previously syncronized items, pics, videos and music, with the previously authorized iTunes on the previous computer, expect the saved pics from the net.
What can I do just like that, simply to keep all my previous contents on my iPad, but have a new authorisation and a right syncronization, without data loss with the new iTunes on my new Mac?
Thanks a lot for your answer.
([email protected])

Here are some instructions that I have posted several times that may be helpful to you as they have been to others. You can simply ignore anything that does not apply or that you have already done.
As Alan stated above - transferring the iTunes library is the best first step. If you can transfer the iTunes library to the Mac, most of this will be unecessary for you to do.
Very Important ....
1. Authorize the computer.
2. Turn off auto sync in iTunes
3. Transfer purchases
The text in italics is from the other thread - non italics are my words.
The following was copied from this thread. This is essentially what you want to accomplish.
https://discussions.apple.com/message/11527071#11527071
1) Without connecting your iPad to your new computer, start iTunes. Click on iTunes. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.
2) Now connect your iPad to your computer and start iTunes.
3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.
4) After it finishes transferring all your apps to your computer, right click on your iPad and select Backup your iPad.
5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.
6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.
If everything on your iPad looks good after the sync, go back and click on iTunes / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.
Read this thread and the support links as well. There are apps that you can purchase that will allow you to transfer photos from the iPad to your computer. Look at Photo Transfer App in the App store and you can search for others as well.
https://discussions.apple.com/message/13016026#13016026
This support site will help you with transferring iTunes music to your new computer.

One final note - you may want to leave auto sync turned off - but that is totally up to you. I never did use auto sync.
