My 1 TB external hard disc (WD - My Passport) stopped working and the NTFS table is corrupted so the drive is unreadable. I haven't formatted the drive so it shows up as RAW. I installed two programs to try to recover the data, iCare Professional and EaseUS Recovery.
Data recovery on large volume drives can be such an agony especially if you are using window's tools to recover the same drive that windows is unable to read. I have had success recovering similar raw and unrecognized drives using linux distros as well. My suggestion: Download Ultimate Boot CD, make a bootable USB or CD of it. Boot from it and launch Parted Magic. Mount all partitions on the drive and see if you are able to access your lost files© them to another drive. If this fails, proceed with Testdisk as MOatz suggested in his comment. Testdisk&many other drive recovery tools are included in UBCD. It's your best bet. Best of Luck
Data recovery can take a while, although I've never seen a hard drive have to take that long to be read from and repair. What kind of state is the drive in, is it making noises, does it report bad sectors, what happened to it to make the NTFS table corrupt?
I'd start by using a tool such as ddrescue (packaged in linux as gddrescue) and imaging the drive to another hard drive of equal or preferably larger size. Then once imaged you can use tools such as Testdisk or Photorec to recover the data (or even restore the file structure to the disk if your aim is to re-use the drive).
If you format the drive data recovery won't be faster. If you are sure that the original problem is with a corrupted NTFS table you could try using some kind of partition recovery software. However the best option is such cases it to use the services of a data recovery company. Data recovery is not an easy process and if you aren't a 100% sure what and why you are doing you might end up losing your data.
Since then I only connect the drive once every month for backup my data. Just now, I plug it into my laptop, the safe remove shows the drive but windows explorer take very very long time when i click the drive and still cannot access the drive.
Sorry to hear you cannot access your files. You can verify if the Passport has any hardware damage by running a test with DLG. If you are unable to recover your files with a data recovery program, there are some recommended data recovery companies on the WD support page that you might want to contact. Check the link below for more information.
Sorry about your problem. You said this was a backup but moving files from the computer to another drive is not a backup. A backup is 2 copies in different places. Does the drive show in Disk management?
When I try to safely remove, it cannot and takes very long time just to show t cannot be removed. I shutdown, take out the drive, then windows becomes normal again, win explorer is normal to access all my other drives interna; and external.
Right now I still trying to recover using icare data recovery again just to see if the data recovered can be read fine this time. Last time, although the data can be recovered according to icare but when I try to play the avi, they are all error.
Well this is exactly what happened to me recently at 3:00am in the morning, tired in total darkness while photographing the milky way I swapped out a full memory card and replaced it with a fresh one. Well at least I thought I did but instead I put the card in the wrong pocket of my camera bag and and when I reach for a fresh one it was actually the same SD card I took out. In a total moment of madness while rushing not to disrupt my series of images I formatted what I thought was a fresh memory card without even checking what was on it!
You think it would be easy to find decent reviews and software for a Mac to recover deleted Photo files but I found most were written by people that had obviously never even tested the software they were reviewing or stating software was free when it was not.
First software on my list is Disk Drill which is claimed by many review sites to be the top free recovery app for the mac OS. So first of all let me just put this right to recover files from a formatted memory card the application is not free! Most people will be searching for software after they have accidentally deleted their images after formatting and to use this software in this scenario you will have to pay to recover your files.
Disk Drill does have some great functionalities such as image preview capabilities which I found great so you can drill down and just recover the images you want rather than recovering the entire card content. This is extremely useful if you have a large storage device to speed up the process of recovery.
The installation process for Disk Drill is certainly not overly complicated where you just install the software like any other .dmg file and drag it to your applications folder. There is an additional step that needs to be performed in the setup process which is granting access for the software to your hardware. This is very simple though as it has a quick link button in the setup procedure which guides you through the process to authorise access and grant the necessary privileges.
It took around 8 mins to perform deep scans of the SanDisk Extreme 32GB SD Memory Cards where it found all of the Nikon Raw files that had been deleted by both types of formats and more old previously deleted files. The total size of recovered data was 39.43 GB in a total of 3267 files.
I then performed the exact same test on the SanDisk Extreme PLUS 128GB Micro SD containing 59 .DNG files and 13 .MOV files. This took around 32 minutes to perform a deep scan of the memory card but it performed excellently and found all the files ready for recovery plus others from previous formats.
Overall performance was good and it recovered all files and more from all memory cards after carrying out both types of formats. As I like to say it did exactly what it says on the tin although not for free!
Labelled as a professional data recovery package for Mac, EaseUS Data Recovery Wizard claims to retrieve photos, videos, music files, documents, emails, and more from Mac-based devices: HDD, SSD, fusion drive, Time Machine backup drive, SD card, memory card, USB drive, camera, etc.
It took around 6 minutes to perform deep scans of the SanDisk Extreme 32GB SD Memory Cards where it found all of the Nikon Raw files that had been deleted by both types of formats and more of the old previously deleted files. The total size of recovered data was 37.38 GB in a total of 3245 files.
I then performed the same tests on the SanDisk Extreme PLUS 128GB Micro SD containing 59 .DNG files and 13 .MOV files and pleased to say it also recovered these without any problems and took around 30 minutes to perform the deep scan.
A fantastic part of the software interface is that you can very easily change the file view to thumbnails which makes searching for the files you want to recover a breeze and one thing that I really like about the software.
The same as EaseUS the installation of the software was very simple and straightforward by simply downloading the .dmg file and installing the software. Hassle free with no issues I was up and running in a couple of minutes.
The one thing I do like about the Stellar software is that is very simple and straight forward to use. Upon launching the software you simply select the drive you want to scan, I found that you need to have deep scan select and then hit go and the software will work its magic.
I found it took around 12 minutes to complete all its scanning phases of the card to find the files to recover. Bear in mind this will be much longer if you are scanning larger drives such as hard drives or large memory stick.
To recover your files you simply hit the Recover button and it will ask you where you want to recover your files to. Select or create a new folder and then select recover. At this point I would go make yourself a nice cup of coffee as this took around 20 minutes for this 32GB memory card.
The result was 1058 .NEF Raw files recovered along with 1058 matching .JPG files. This included all the original 44 Raw files and more which open perfectly in Lightroom and Photoshop as if they were never deleted. Performing the same test using the MAC DiskUtility Tool to format the memory card I got the same results and the software fully recovered all of the deleted files.
For my final test I wanted to check how good the Stellar Recovery Software was at recovering video footage from my DJI Mavic 2 Pro micro SD card once it had been formatted. Hopefully I will never have to use it but it is something that I do regularly so it will give me peace of mind if ever I make a stupid mistake in the future.
So I thought I would give it another go and swapped out the camera SD card for the Micro SD card from the Mavic 2 pro with exactly the same outcome, it totally messed up the software and I was back to square one where it could not recover any files.
I have since sent two emails to Stellar explaining the problem in-depth and asking them if they had any thoughts on why this could be happened. I have had an acknowledgement to my emails explaining it is taking them longer than usual to look at the issue due to Covid19 which I think is perfectly acceptable and will update this post once I get a resolution.
Installation: For ease of installation I would say that both Stellar and EaseUS are on par with each other and its simply a case of running the downloaded file and then dragging across the .dmg file into your applications folder like any other piece of software. Disk Drill has an extra step in the setup where you have to configure your security settings to give the software access to your hard drive. There is a link in the setup window and takes just seconds to do so it certainly is not a deal breaker, just an extra step.
Overall Speed: Well EaseUS just edges it for me over Disk Drill and again there is not a lot in it but I found EaseUS marginally quicker. Stellar Photo Recovery came 3rd in my tests taking the longest to deep scan the memory cards and recover the files overall.
