Windows 10: Losing Disk Space Rapidly

Hello, I recently signed up for the Beta Channel in Windows 11 because I wanted to test out 23H2. Within hours of using it, I realized I started losing large chunks of disk space, which has been quite a concerning experience. Initially, I noticed that I had lost an estimated 10 GB of storage after the update. However, things escalated quickly; about an hour later, it had dropped to just four gigabytes. Now, as I'm writing this, I have quite literally 0 bytes left on my Hard Drive. My journey to Windows 11 started less than a month ago when I upgraded from Windows 10, and I certainly didn't a

disk space reduced after media creation tool

Hi Sarah,

One of the possible reasons why your disk space was reduced is due to an unallocated disk space on your partitions. For us to isolate your concern, we suggest that you check your device's partition. To do this, follow the steps provided below:

• Type Computer Management on Ask me anything and press
  Enter.
• Select Storage and click on Disk Management.
• Send us a screenshot.

We look forward to your response.

 

Losing Disk Space By The GBs

Others have written about this; I guess it's my turn now. I have a 1TB hard drive. After installing W10 years ago and adding everything else, I had about 880 GB of free space. Over time, of course, that's gone down, but it eventually stabilized at about 870 GB. In the last few months, and particularly recently, I've lost space in multiple GBs. I could lose 5 GB in a day for no known reason. How much free space I have now depends of what source I look at. Windows says it's 839; CCleaner says it's 859. 859 would be great but not what it should be as far as I'm concerned. I clean about once a week, using Windows Disk Cleanup, CCleaner, and other products. There's no Windows.Old. There's no huge list of log files anywhere that I know of. Any 'usual suspect' that you can think of probably doesn't apply. Also, every now and then Windows will clean itself, and I get back several GBs. Also, re-starting the machine will sometimes result in re-gained free space. Still, the drop has been dramatic. I don't use Storage Sense because it says it will clean when disk space is low. I'm not at that point and hopefully will never get to that point. I don't use the Windows File History feature. Right now there's only one restore point. I've attached 4 screenshots. The first one shows everything with a non-zero amount of space. I know there are several software products that will analyze the content of a disk drive. Will any of them do a meaningfully better job than what CCleaner shows? Or have I given enough info that somebody can come with an answer already?

 

how to do partition in a disk without losing data

Hi Vinod,

Yes, you can create a partition in a disk without losing your data by using
Disk Management.

Here's how:

• Search for Disk Management from the Cortana search field.
  
• Click on Create and format hard disk partitions from the results.
  
• Right-click the unallocated space, then click New Simple Volume.
  
• Click the Next button from the window that will pop-up.
  
• Make sure that you input a size in the limit of the available unallocated space. Continue the steps to finish creating a partition.
  

Let us know how it goes.
