I want to know if I delete my HDD data permanently then does it goes out fully or keep on somewhere in the drive. I want to put up for sale my hard drive . I had formatted every partition of it, but is it possible to recover data out of it? I want to delete it permanently?Any help regarding this topic is appreciated. Thank you.
Yeah it is very imp to delete all the sensitive data b4 u get rid of ur old system.The simplest way to do this is to format all the drives,but that too may not delete all the data and there are always chances to recover them.I can suggest you 1 tool that will remove all ur data permanently forever and no other tool can also be able to recover it."Advanced System Optimizer",has a tool named Secure Delete that does the permanent deletion of the data,but be cautious once the data removed can not be recovered anyhow.
U can download its free version from cnet

I need help to recover data (photo, contacts, WhatsApp chats) from my Un-Rooted GT-I9506 running Android 4.3. Due to some error the data was not synced for about 6 months.
Any help as the steps that I need to follow is greatly appreciated
The what's app chats should re-appear if you reinstall what's app and sign in on another phone.
So the phone won't boot at all into the rom? If not, you could install twrp using Odin, boot into twrp, mount the data partition, and copy the data to your computer. Before any of this will work, you need to make sure that the phone is seen by your windows computer.

Thank you audit13 for your help.
My GT-I9506 is working perfectly fine so I should be able to install TWRP.
However I made a mistake and loaded the TWRP ment S4-I337M. I got the usual Green OK message in ODIN. However when I pressed Volume Up & Power I was getting the usual Samsung Default Recovery Options.
Then I realized my mistake and loaded TWRP_3.0.2.0_ks01lte_20160508.tar.md5
http://forum.xda-developers.com/gal...recovery-twrp-2-8-1-0-touch-recovery-t2942159
I got thw Green Successful Message in ODIN. But when I press Volume Down & Power I get the following message:
Recover Booting
Wet Warranty Bit: Recovery.
And the Samsung Galaxy S4 GT-I9506 in the Black Screen logo
The phone is stuck in the above screen
Phone is working fine (I am able to use the phone and to go to Download Mode).
What should I do?
Re-flash TWRP. I recommend re-flashing TWRP. I like and still use 2.87.
https://twrp.me/devices/samsunggalaxys4ltea.html
Open Odin, uncheck auto reboot, flash TWRP and, when you see the word "reset" in the status window, remove USB cable, remove battery, replace battery, use button combination to boot into TWRP.

Re-flashing with 2.87 worked. TWRP is working, Thank you very much.
When you have time can you please point me to link that have step by step instructions to recover the data?
Boot into twrp, connect phone to computer, open file explorer and look for your data. If you don't see anything in the data partition, you may have to try using a data recovery program. Try a program like recuva.

Thank you so much for your help. The files were deleted so I could not find them. I have downloaded Recuva.
What is the Optimal way to recover All deleted files using Recuva?
I did a search and this what I found and I not sure how to do it:
back up the entire internal memory partition to your computer as a single, massive .RAW file,
convert the .RAW file output to a VHD,
mount the VHD as a disk in Disk Manager,
scan the attached VHD volume for files that have been deleted and recover them,
Sorry, I have never use recuva on a phone or non-volatile memory. only mechanical drives.

When I boot GT-9506 into TWRP and mount the internal storage as USB my PC is not detecting the phone internal storage. Even Recuva or HDD Raw Copy Tool is not detecting the phone internal storage.
Any suggestions?
Does TWRP's file manager see any of your data files?
How was the data lost?
- Did you delete it manually?
- Did your format the device?
If so, then it's IMPOSSIBLE to get your data back. That's because Google enabled TRIM in Android 4.3+, so data you deleted is really gone.
If you are stubborn like most of the users and still want to waste lot's of time trying to recover the data then this is the thread you are searching for.
http://forum.xda-developers.com/gal...de-internal-memory-data-recovery-yes-t1994705
TWRP File Manager seems to show all folders example: boot, cache, data, dev, ect, external_sd, license, preload, proc, recovery, res, root, sbin, sdcard, sideload, spersu, system, tem, twres, usbstorage, charger, default.prop .......
When I go into the data folder I see a lot of sub folders including app folder, app-asec, app-lib, app-private, audio, backup, mcmnfc .......
What I go into app folder I see some app files such as "com.whatsapp-34.apk, com.viber.voip6.apk
I am mainly trying to recover deleted Whatsapp & Viber chat, calls history

The data was deleted manually but it was not formatted nor a factory reset done.
Yes I did see that 100 page long thread. But as mentioned in this tread my internal storage is NOT detected by Recuva or raw HDD copy utility.
I need the deleted data very badly. So I am willing to jump through any loops

If you deleted the data manually then you cannot get it back. There are no loops to jump through.
Android 4.3+ has Trim enabled. The TRIM function effectively nulls out the space where deleted files were stored, making the data completely unrecoverable.

I am not too sure about that because I used a software called Dr Fone and was able to recover some of the deleted files.
Does anyone know of a method to force the J5 phone to use the SD Card for cache files without rooting?
I've only had the phone a week and already internal memory is getting very low. I thought if cached data could automatically go onto the SD Card I would gain a bit of space. Having looked at the threads regarding rooting the J5 I think I want to take more time to understand the process rather than a leap in the dark.
Many thanks,
Anne
You can access your storage and execute clean cache to wipe out all these unwanted files in a few seconds. It is in the settings menu.
Cache; whether stored in your phone memory or SDcards would eventually eat-up your storage and eitherway, not a good thing IMHO.
Hello Anne, Rooting Your Galaxy J5 Is Quite Easier Than You Think, Provided You Have The Tools And Follow The Instructions. Try Using TWRP Recovery By @Nick Verse, Flashing Instructions Are Well Detailed On His Thread. I'm Sorry I Couldn't Provide The Links But You Can Search It. Good Luck
Hello guys! Cache partition is only 200MB on our device, so it is not the issue here. You must move your applications to SD, but you will experience some lags, due to I/O speed limitations.
Furthermore, if we move cache to SD, more lags will happen.
Can be used an init.d which clear cache automatically, or use Tasker app to clear cache whenever you want (I prefer Tasker).

Why don't you simply wipe cache from recovery?

It can be done with some terminal command, can't remember it right now, but can be found on Google. Is easier this way and isn't necessary to reboot the phone.

Thanks for all your replies. I've been clearing cache and generally getting rid of junk but the internal memory was almost 95% used nonetheless. No programs were able to update and taking a photo meant having to delete another.
So bit the bullet and after more investigation rooted the phone today. Tomorrow I shall partition the sd card so that some of it (the majority) can act as internal memory. <rant>Don't understand why Android (Google) have such limitations in their op system. More and more apps are available and they get larger and larger so more and more memory is needed. Currently memory is as cheap as chips, so why limit how and where it is used?</rant>

Hi all sorry for asking a dumb question, but would "format data" button inside TWRP's Wipe section (the button above factory reset) also delete a TWRP backup?

If your twrp backup in microsd card then it will not delete.
"Format data" will delete ( system/data/cache/dalvic cache/internal storage)
If you are planning to clean your device to install new clean rom then Make a backup of current rom and all your data in microsd card/usb drive before you do this.
So if the backup was in the internal sd it would have been deleted then right?

Go to my files and copy entire TWRP folder from internal storage to microsd card if you need your backup.
Thanks!

After FORMAT DATA there is nothing there to recover.
Everything has gone, sorry.
Only if you had made a TWRP backup, stored in the external sdcard, then you could restore it and get your DATA files back.
But in that case also, your personal files(pictures, music etc) are not included in this back up.
Only APPS data, meaning files that make apps working, are restored this way.
ALL your personal data, are stored in the internal storage.
If you have performed a DATA format, nothing is there anymore.

So you can recover data if it was not overwritten, even if it was deleted. You can use special software.
Which options do we need to select to backup existing ROM? And to do a recover in case of device failure.
Boot? System? System Image? Vendor? Vendor Image?
Maybe a dumb question but: If you format data, can you boot in current rom?

No, you can't lol. Format data wipes everything on the storage of the device. You better install a rom after wiping everything or you will get stuck in bootloader / bootloops.
In some a/b slot devices, if you don't have a rom installed, your custom recovery is also wiped because it usually resides on the boot.img.

Hello, i am gonna answer your questions one by one
1. by apps positions if you mean the apps on the screens of the android then they are gonna moved after format, even after restore your backup. second you are gonna need titanium backup from playstore. Since you have root download lucky patcher from your browser or from your pc and patch the titanium backup you just downloaded from PlayStore .. and then select backup your apps, i suggest you to backup the on a usb with the adapter from the box of your phone , or on a sd card, be carefull do not wipe them . the contacts you can go to the Contacts apps and on the settings back them up to your Sd Card or to your Usb Otg.. Unless if you have them moved on your Sim Card then no need to backup them
..
Your videos and your other personal data move them all from the internal storage to your Usb or to Sd card too ..
2. you dont need to unroot your device to update your device, which methods are you gonna use to upgrade your phone? firmware from odin ? You are gonna need to root your device after the update then .
3. if you use titanium backup then you are gonna find the restore option on the app . your personal data from your usb or sd you are need to move them on your internal storage , and restore the contacts.
Get titanium, backup needed apps on external sd. Instal twrp through odin, insall custom rom like alexega or sac (wipe system and data before or some roms already offer this options).
Later restore backups of needed apps through titanium. All files on sd card/s will remain after new rom installation (if you are unsure backup your media files to computer), just dont wipe media/internal sd. Forget about restoring full backup, if you have a lot of rubbish code flowing around you need get rid of it, just back up apps with data that are important. That's how you should do it.
Ps: Ideally everyone should format data once 3 months and restore backups of needed apps later, it's the only way to keep it in excellent working condition

Also while we are at it!
What's the difference between wipe and format
So I got the oem lock thing and i have to wait 7 days etc
So when I get the poem unlock I'll be rooting my device
But to install tarp and magisk I have to "wipe" data
What exactly will be wiped?
My pictures and videos or apps or what exactly so I know before rooting

It's same but it very differnt. it's confusing. Format data in this case applies to full data wipe. While if you go to twrp wipe menu and choose to wipe data, it won't touch media (folder with all user files) folder in data. While format will erase all patrition and reformat it.
All will be deleted, since it's full data wipe with media. Just data wipe without media deletes just apps. You won't need to install magisk or su separately if you install custom rom like i mentioned.

Well I ended up installing the official rom for oreo I'm waiting for oem unlock soon, I wanna install twrp and root using magisk, but one of the requirement is to "wipe" in this case it's just the apps? I'm gonna backup just in case anyway! But I want to make sure
All will be deleted no reason to make surerer. I hope you understood titanium part, although i recommend it only if you have important apps, with data that i use (i have only a few), otherwise throw them out.
Then after you installl, you can make full backup of data through twrp. I usually do it after a week i installed rom i choose, and if i install a lot of apps i no longer need, and overall android gets slower, i just restore this back up and always have os that is 1 week old without any setting up to do. After just a couple of apps i restore recent data to them with titanium. If you had this with phone it becomes problematic as you said, i suggest you to remember how to do it.
