My hard drive partitions are not accessible. How do I recover data using Stellar Data Recovery Professional?

 Modified on: July 26, 2021 |    23540 views

Stellar Data Recovery Professional for Windows software allows you to search and recover data from lost or deleted partitions of a hard disk. You should use "Can’t Find Drive” option from main interface to recover data from an accidentally deleted partition. This option will search and list all the deleted and lost partitions in the hard disk along with existing volumes.

  • From "Select What To Recover Screen" screen, select the type of data i.e. Everything, Documents, Folders and Emails or Multimedia Files, you want to recover.

  • Click Next.
  • On Recover From screen, select "Can't Find Drive" from Other Locations.

  • Click Scan.
  • In the Select Drive section all the hard drives connected to the system are listed with their details. From this section, choose a hard drive you want to scan for lost partitions and click Search. A scan for lost or deleted partitions will be performed in the selected disk or drive.

  • Any 'lost partition' detected, will be listed in the Partition Found section.
  • From the list of partitions found, select any desired partition and click Scan to continue with the recovery process.

Note: If you can't find your desired partition in the Partition Found section, you can choose Deep Scan option to perform a comprehensive scan of the selected drive for deleted or lost partition.

Does not find external drive that shows up in list of devices but partitions corrupted.

Hi Larry,

If software does not list the drive from where you want to recover data in that case data recovery is not possible.

i have recovered all my pictures, incl ones (like BMPs) that i dont really want. However it is incredibly slow, and i now want to be a bit more selective about what i recover to save the time it takes. Can you advise how to restart the process.


Hi Nick,

The software supports selective file recovery so could you minimize the time taken to complete the scan process. You could select files of your choice to scan and recover as well as add additional file type using 'Add File Types' of this software.

To do so, go to 'Settings' button located at the top right corner > select 'Add File Types' tab > On the 'File List' screen, click the desired file types that you want to recover.

Give it a go and see if the process may able to reduce scan time and your overall experience. Don't forget to leave response/feedback about the same.

My "quick" scan has been going for about 15 hours and the progress bar has barely moved. It spent all night scanning through the sectors (x out of 356017024), then restarted from zero! Is this normal? I'm worried that my already malfunctioning hard drive won't survive this much nonstop use.


Hi Daryl,

Quick scan is used for fast scanning and quickly recovers data. However, in your case, it seems pretty non-obvious as the scanning process is running for over 15 hours. I'm afraid that your hard drive might have some failing equipments and won't allow software's to perform recovery operation properly.

I'd recommend you to create an image of entire hard drive and later performs recovery from the created image. Image copy will includes the entire data currently stored on the drive and could be salvaged easily using the software's 'recovery from image' operation. From the software's home screen, choose advance options > Create Image > Choose Drive and click 'Create Image'. Create image copy will be listed on the recovery from image tab, choose the same image and select subsequent options for recovery such as 'Quick Recovery', 'Advanced recovery' or 'RAW Recovery'.

Don't hesitate to asks if any problem is resurfaces.

Good Luck Though!!"

Amit, thanks so much for the fast reply. I'm trying what you suggested, although it seems to be the same issue - incredibly slow. In three hours it has only processed 7 mb (out of 173324!!!). At a rate of 2mb/hour, it will take forty years to finish haha! I don't blame the software though. I think the hdd may just be too damaged for software recovery.

At this point I'd be happy just to be able to see what's on the damaged disk. What would be the fastest way to simply scan the disk and see what's there? Should I try Quick Scan again? It's the hdd from my old pc, so it has a lot of stuff I don't need, like the OS files. I put it in a hdd enclosure, but my computer only recognizes it as an uninitiated disk, so I can't access it. I really just need to see one folder, so I at least know what data is lost. Thanks for any advice.


Hi Daryl,

HDD goes bad for sure. Lets give it a one last try!!

Put your hard drive in a plastic like bag and place it in a freezer for an hour or two. Please make sure that hard drive shouldn't be there for more than the time mentioned.

Next, pull it from freezer and plug it externally(via USB/SATA/IDE cable) to any working machine that's free from malware/trojan and fresh install the software. Now the hard drive will be listed under 'Drive Recovery' tab, choose the drive and then 'Advanced Recovery' from the pop up windows that opens automatically after choosing one of your drive. Under 'scan as' sub option, choose 'NTFS' or 'FAT' based on the hard drive current file system.

If above fails, the last resort is go with data recovery services. Pretty costlier but you got no other ways to see your data back.
You can choose any data recovery services provider around your vicinity or choose Stellar, which provides home pick and drop facility for your damaged hard drive. You can get more information about data recovery services from here:



Scanning my accidentally formatted external hdd right now. With an advanced scan. He's reading a lot of clusters but hey only finds 99 entries (12 gb). Should be way more. Or am I doing something wrong and are deleted files different from files on a formatted disk?



Dear Ron,

We request you to provide few more details so we could serve better solution for you:

1. How much older the external hard drive is? Its overage might causing software to not proceed further and hence, shows limited files.
2. Check and make sure that the power cable and USB you're using to connect external HDD were not in damaged state or working properly. It would be better if you could try scanning the software using different cables and on the different system, if you've any.
3. Perhaps the deleted files were overwritten or heavily damaged, I'm afraid. If that's the case, you're not going to get your files back again.

I'd recommend to start a fresh scan after considering all the precautions mentioned above and see if this time you could able to see the desired deleted files.

Looking forward your progress on this.

I reinstall windows on my pc but i am forget to backup the my documents folder and now i am in a jam. I install the stellar professional but i am not finding the files. Can stellar recover files from a delete and formatted partition after you do a fresh installation of windows 7 and how?


Hi Mark,

Stellar Partition Recovery - Professional can recover files from deleted or formatted hard drive partitions. Click on 'Click Here to Search Lost Volumes' option located under 'Drive Recovery' tab, at the bottom. Depending on the problem drive storage capacity, scanning process for deleted or lost volumes will take time. Don't pause or abort the scanning process as it'll carefully look for all the storage area of your hard drive.

Once the scanning is completed, you'll be able to see the desired lost or deleted partition that software can recover. Select any desired problem partition and choose subsequent option for recovery i.e. Quick Recovery, Deleted Recovery, Advanced Recovery etc.

You'll also able to see preview of files that you can recover before actual recovery.

Good Luck!!

My SSD has become raw format. I have a clone backup of my ssd but it is very old. (About 1 year)
Is it possible to replace the MFT file from old with corrupted. Will it work or not?

Because Stellar says that "no data found"




As per your concern we will contact you through email.

I was attempting to do a system recovery file but accidently selected my data drive on my w10. The drive then showed as unallocated, I re-allocated the drive to the same drive letter G.
I am attempting to the data on a 1 tb byte drive, there is approximately 150 gb of data on the drive, it has been recovering for 3 days, I notice that in the copy to drive, the data recovered has numerous copies, example: 16 copies of(Copy16_$volume) plus several others.
In the Stellar Tree View I see all the folders that were on the drive.
There were options earlier in the recovery (replace files) which I selected.
The recovery has been working for over 72 hours.
Currently Stellar is Saving Data (Saving Files...)
Is this normal?? or did I select the wrong options?
Please advise!

I bought the stellar data recovery software to recover a lost partition. When plugging into my Mac my external hard drive I get the message 'partition map check failed because no slices were found'. I run the lost volumes scan on stellar but came back saying that no volumes were found. Does this mean there absolutely nothing to recover in the hard drive? There was a lot of data in there in photos.

Just wanted to know data backup taken on external drive system is been formatted for both the partition. after installation.

Restored data again but user says he had some more data on the desktop which is not showing in the backup as well.

How to recover that data from C drive user profile desktop



Dear Santosh,

We believe data backup was not done properly because of which the client is unable to see all the files or folders of a desktop after restoration.

We suggest you to try the demo version of Stellar Data Recovery for Windows application and check whether or not lost data is getting listed after the scan.

My ext hd is not listed under connected drives, but when I try the can't find drive option, my ext hd is listed. Does that mean there's still a chance to recover my files? But after 12+ hrs, it's only 868582 of 3907029168. Is this normal?



Dear Eu,

Yes, recovery would be possible. The scanning time depends upon the size of the drive and corruption on it. We suggest you to continue with the scan and wait until the process completed.

Hi, I accidently formatted my external HDD when I was trying to install Win10 on it yesterday. I have run the Stellar Scan on the "Can't find drive" option, but after scanning for 6 hours, it couldn't find any files, except for the ones from Win10. Does that mean all data is lost forever?

William Chiu


Hi William,

Please confirm whether you have performed a normal or deep scan. If not then we suggest you to perform it.

In addition, when we perform Can't Find drive scan it search the previous formatted/lost volumes then you need to perform a scan on them to check the possibility of recovery.

Kindly confirm whether you have performed a scan on retrieved formatted/lost volumes or not.
