Hi, I'm trying to recover some old deleted files on one of my SD cards, I usually use disk internals uneraser but all the files its restoring are still corrupt and so cant be viewed (photos), is there any better tool to recover with? I tried photorec but its really confusing :S. I really need these files back, has anyone got any ideas? I would be greatly appreciative

Hey guys, thanks for all the input but so far none of these have worked, they've either only found some files, or any of the files I want are too corrupt to use, the problem is I need some of the older photos, deleted a few months ago. I need a really powerfull program..

Well the cost isnt an issue if you know what I mean
really sucks that I cant get this picture in particular back
Once I had to recover a memory stick that was corrupted and I was forced to reformat and got reazonable success with PCtools File Recovery.
On the other hand, tried using same on a friend's stick without success because she had partially reused (overwritten deleted files) the stick. It also works on sd cards inside small card readers that look like memory sticks.
There is also another application from sony called Memory Card File Rescue: http://esupport.sony.com/US/perl/swu-download.pl?upd_id=2159&SMB=YES
but you will have to provide some sort of sony card type id to be able to download it, but it works with sd cards also as far as I tested but is less effective.

I didnt try the sony one as you said its not as good.
I've got everything backed up with the appmonster.
Will this be adequate prep for flashing a ROM?
Are the backup files stored on the external SD card?
Is it easy to retrieve your apps after flashing the ROM?
I gather only the internal SD and phone memory will be reformatted.
I'm I ready to go flashing?
Check the App Monster's description at AppBrain (and the program's settings of course, where did your phone saved the needed files)...
Did you saved the SMS and call log? And what about Titanium Backup? Have you ever tried it?
Did you download all the needed files before doing ROM change?
I would say that when you can answer these questions yourself, then maybe you are ready to flash roms. Do not rush in, read plenty, get familiar with the lingo, procedures, ways to salvage a bad flash etc etc....when you are comfortable then proceed. Read all the faqs, then when you need help people will be far more helpful.
Also make sure you have 3 button d/l mode.....and enjoy! It is addictive, fun and harmless! Welcome

I tried Titanium Backup, but it says I gotta ROOT first. I was going to try to ROOT and ROM in one go with the Darky's ROM v10.1.
Monster saved all the apps, I have to study about whether the contacts and logs were backed up too.
I'm just a little confused about what exactly happens when you flash a ROM.
The way I understand it it's like reformatting and reinstalling the OS on a PC.
Where I'm confused is about the internal SD card. Does that get affected? I know the external SD doesn't experience anything.
One my complications is that I don't have a PC, and have to borrow one to get the flashing done.
I've been considering a netbook. But I want to run Unbutu and not windows!
I used to have a windows partition on my MacBook but I ran out of space for it. I hardly ever used it.
I was hoping getting the SGS would get me away from PC's and Mac's.
I guess a cheap netbook wont kill me; and sparing 30Gs for a windows partition now wont be such a bit deal with these nifty 320-500G hardrives out there now.
Maybe I should just have someone slap a fancy 500G drive with flash ram in the MacBook then problem solved.
Fark but I'm also getting old and lazy.
Maybe I'll just wait and study this all a bit more. The phone works pretty well with Froyo anyway. The only real issue is that it eats up the battery fairly fast.
Hi,
I made a mistake and I tried the beta version of the ICS which made the counter counts "1". To get things even worse, the mobile stopped reading the memory card and I had to format it and I lost all my file in that memory card. How can I get them back and rest the counter?
I tried the "How to remove yellow triangle on any firmware with JIG" but it didn't work.
Help
First of all, Dont put any files on memory card if you want to recover data. As if it overwrites older data, you won't be able to recover old files.
Connect your device with USB debugging mode, then select connect device from notification
Now you will get separate drive letter for memory card.
There are lot SW available to restore data, i know one is 'Get data back', google it n try recovering from memory card drive.

If you formatted it already then it's possible that you'll never be able to recover the files. If you have access to Linux -- e.g. via a liveCD or something -- you can try a command-line utility called 'magicrescue', but even then it's not guaranteed it'll be able to rescue the whole file.

simple format just making unable to read, so still it remains recoverable. If data where it is located on sector, overwrite with other data, thn only it becomes non recoberable.
Low level format only erases data completely, but i think nobody routinely using it.

I did link to magicrescue, didn't I? And no, even a simple format that resets the allocation table can still result in files not being possible to recover, it all depends on whether the file was fragmented or not; if the file was written to non-consecutive blocks on the card then there is simply no way for a program to know where all the blocks are located without the allocation table.
The tools that try to rescue files from broken/formatted filesystems rely on the fact that they can find the file header and that the header format is known to the rescue utility. As such those tools cannot rescue filetypes that they aren't familiar with or for which the user has not supplied the proper settings.

Low-level format is when you have access to the actual barebones hardware and can read/write e.g. the internal CRC-structures there. What you are referring to is not low-level format, it's just plain old regular format.
Now get off my lawn.
I was tinkering round this morning and looked into my devices storage and saw that 27gb of 32gb were being used.
Did some math on my own:
Apps: 2.82gb
Music: 3.23gb
Photos: 1.12gb
Other: 19.85gb:
-Nandroids: 9gb
-Titanium Back up 1gb
2 roms: 1.5gb
Somewhere in the "Other" category something is eating up 9gb of space. I used my file explorer and couldn't pin anything that big down. I am going to offload my nandroids but I shouldn't have to.
Anyone else run into this or know what this 9gb "other" hog could be
Is there an app or system setting I am missing to ID this?

Your 'other' is really suspicious. Mine is ~7GB. I'd do a factory reset, easiest way IMO.
If you're flashing roms or doing backups with any other apps (CWM or something). I'm guessing they would go there. Check your download folder as well if you do a lot of downloading.
You may also try installing airdroid and using the desktop filemanager to whittle down your list as well.
Download Disk Usage. It shows you visually whats taking up space. It's amazing.
Thanks for advice using disk usage. I don't know why I didn't reinstall that sooner.
I did some digging and searching around the interwebs and found out this is a known issue. Other people have noticed it in droves. From my early intel: when you delete files you lose data blocks and they are marked as bad. If you ran dsk chk they would come up as corrupt. People are losing more storage space than I did.
2 solutions came up:
1. Reformat your SD: Copy everything to PC>reformat>copy everything back....time consuming but worked from what I could tell
2. There is an update that has been released overseas(asia, india, etc) that seems to fix this issue. It's a known HTC ONE issue so maybe someday I will see an update that will fix it.

I couldn't just let this rest. I like to flash roms and knew I would need strorage space for some nandroids in the future. Here are somethings I tried and had issues with.
Formatting the SD card: I could not for the life of me get this done.
-Nothing in TWRP
-Couldn't do it in windows
-Couldn't mount the sd in TWRP or regularly and get it to show up in windows file explorer as a drive to format
Eventual solution:
I formated the data in TWRP using the format data option. I copied everything over before I did it. When I came back I flashed a new rom and was still missing 7 gb. No apps, no music, nothing. SD card was empty still only showed 25 gb available.
Conclusion: I think I have some bad sectors in their somewhere. I read that I could go back completely to stock and try to star this whole process over.
One question: Can I unlock using HTCdev as many times as I want or is it a one time thing?
Anyone else in the same boat?

If you go back completely to stock, your bootloader will probably still be unlocked (unless you relock and use an RUU). The code you got to disable your bootloader the first time around will work however many times you want. To be honest though, I wouldn't be surprised if that 7GB were used by the system ROM/frameworks and I'd be even less surprised if you still found files on your SD card in a .Trashes folder or something from earlier. Formatting data tends to leave weird remnants all over the place.
Also, +1 to the Google Music thing. Definitely shows up in other for me.

Do you have a custom recovery? If so, try running Fix permissions. It'll tell you for one if it hits any errors (because it finds files it can't change perms for), and may help with the issue (or use the Fix permissions tool in ROM Manager if you'd rather not use recovery).

Clockwork gives you the ability to set a swap partition but not a true reformat

Have you tried TWRP's advanced wipe? If you haven't, it's worth a shot, but I cannot stress enough that you should be careful. This is exactly the kind of problem that you can bork your phone trying to fix for no good reason.

I've been having the same problem, but notice something interesting. My phone said I had almost 20GB in the other category, and I didn't know why.
I downloaded disk usage to get a detail view of what's going on in my storage and I was able to clear 12GB with just deleting old downloads, TWRP backups, Titanium Backups. Still cleaning house.
Also after doing some research, the data that's stored by your apps (ext. PS3 Trophies is a 8mb download, buts it's total size is 31mb on the phone) is counted in the Other section and not part of the app data. So the more apps u have like this installed, the more likely the Other section will balloon in size.
Remember, when u remove and app, it's stored data is still in the phone storage.

I use disk useage but it doesn't even show my max storage space as 32gb. It shows 26gb. See Screenshot: So I have 6gb that aren't even registering as available storage. I was trying to clean out some old app storage but the space they use is so small. Would they be worth it? I think the fact I am missing 6 gb is more troubling.
I could be wrong, but doesn't the phone only have 27GB of formatted space?

Is OTG standard in Android? Does the One need to be rooted?
I'm hoping someone can help me.
My wife has a Note 8 (N950U) and she accidentally deleted her entire camera folder. I thought she was backing up to GPhotos but she wasn't. She had no cloud back up, and the photos were saved to internal memory not an SD. She has some photos that she is desperate to try to recover (including the last photos of her mother before she passed away). I'm fairly technically savvy, but I haven't messed under the hood of Android before. From what I've read, the only way to try to recover deleted files in this scenario is to be able to run a utility like DiskDigger as root (and I'm aware that there is only a small chance that the photos can be recovered).
So I think I need to root the phone and I don't plan to leave it rooted, just need to root it long enough to run the recovery utility and then put it back.
I see there is the SamFAIL method to root but... do I understand correctly that it will only work on Android 7? (her phone is on Oreo firmware version N950USQS5CRID)
So I read that if you are on Oreo and want to use SamFAIL, you could downgrade to Nougat first and then follow the SamFAIL process. But I have had zero success with getting a downgrade to work. Is this a possible path or does the firmware loaded on this phone completely prevent any process to get to root?
Any help would be appreciated!
Thanks
No root for Snapdragon Oreo and you can't downgrade. And do check this Q&A section, threads like this already exist.
Once you upgrade to any firmware version that has a higher bootloader version, you can never go back to anything with a lower bootloader, even if it is the same (nougatt,, oreo) so,, any oreo firmware will always have higher bootloader versions than a nougatt one, besides,, once you root, samsung pay and secure folder will be gone forever,, there is no way to get them back, no workaround, no trick,, nothing will do
Try running Data Recovery software on it. If she has written over the sectors, which contain the photo's data then you won't be able to recover it.

You don't need root access. If you connect the device to a computer and run the recovery software via that. You should be able to recover all the deleted data from your device that way. Using a data recovery app on your device requires root access.

Its not possible to recover photos from android internal storage by using any kind of methods. There are various reasons for this.
The internal storage is encrypted and no third party software knows about the process. Even TWRP cant mount the storage with encryption.
The MTP protocol prohibits windows recovery tools to access the internal storage directly.
By now, the physical area might have been overwritten and data would have been lost already.
Sorry, but still, i suggest you to go to files, turn on show hidden files, navigate to dcim/.thumbnail. there might be some photos available either in internal or sdcard.
Good luck.

Firstly, rooting the device you will need to format the internal storage, anyway, to get rid of the encryption, so doing that your wife will lose everything on her device, anyway. This includes apps, music, videos, and anything else she might have on it. It's like doing a factory reset. So that wouldn't have helped your cause.
Second, apps like DiskDigger doesn't actually recover anything, either. I tried it before when I lost some photos. All it does is scour your device for thumbnails of images. Some apps save low resolution thumbnails, some save slightly higher resolution, but even if it finds thumbnails of the images you want to recover, it'll never be the same quality as the original ones. This is from my own experience of using this app and one or two others like it.
Thirdly, flash memory works a little different to hard drives and Android also works different to Windows. When you delete something off flash memory, it doesn't necessarily just mark the file as deleted or keep remnants or something, like Windows does. You can test this yourself by copying something onto an SD card, then deleting it and sticking the SD card in a computer or laptop and running data recovery software on that. Chances are high it won't pick up the deleted content.
Sadly, like sandeepkumar0153 said, your best and likely only bet is to look in the thumbnails directory to see if there's thumbnails of the images, but be prepared that those images will be very low resolution. It might really be worth it.
My advice is to make peace with what happened and start getting into the habit up backing up important files like that. I've lost many, many photos and other stuff due to the same issues or situations where I couldn't boot the device and had to do factory resets. It's sad and painful, but it happens.
