My disk space is gone

Hi John,

Thank you for posting the query on Microsoft Community.

I do appreciate your efforts and time.

Try to run theSystem Maintenance Troubleshooter.

hard disk space

Hello,

Taking into consideration that the free space is shrinking fast, it is possible that your system is creating restore points. To
delete restore points except for the recent one, simply follow the steps below:

• From the Cortana search box, type Disk Cleanup and click on the first result.
• Once the Disk Cleanup window appears, select the
  More Options tab.
• Under the System Restore and Shadow Copies column, click on the
  Clean up... button.

Once done with the steps, see if your disk space has expanded.

If you have further questions, please let us know.

 

Question on disk space avail RAID 0


To update everyone on the conclusion, I successfully converted the RAID0 array to GPT! These were the steps I did:

1. Backed up image of the drive (it was my bootable C: drive) with Macrium.
1a. Changed BIOS boot options setting from legacy boot option to UEFI with hybrid with CSM
2. Booted with Macrium rescue image (note I had not updated by rescue USB, it was older and under "fix boot problems" only had Windows 8 but this all worked. I have since updated it to the latest, supporting Windows 10.)
3. Go into diskpart, clean the drive, convert to GPT, create the efi and msr partitions: the commands in diskpart -
list disk (find which disk is the one you are working on)
select disk xx
clean
convert gpt
create partition efi size=200
format fs=fat32
create partition msr size=128
exit
4. Close the command window, then use Macrium on the rescue disk boot to restore just the volume with my data out of the image, onto the unallocated space of the drive. Be sure to expand the sliders to take up the whole space in this partition. Then let it restore.
5. At this point, I did "Fix boot problems", rebooted, and it could not find the disk. Not sure why, I did the "Fix boot problems" again, rebooted, and it worked fine! All the data was there and Windows 10 came up fine, I verified in diskpart the drive was GPT plus the space was now 3.72 TB available, not 2 TB.
6. Changed boot options in BIOS to UEFI without CSM, and verified system and rescue disk still booted. I did this step with the newly updated Macrium Rescue image USB drive, full support of Windows 10.

My only question - in step 6, once I changed the boot option to UEFI without CSM, the rescue disk takes about 3 minutes to boot - the light blinks the whole time, but it does come up fine eventually. Before, the rescue disk would boot up in about 20 seconds or so. Same USB drive, same port. Why is that?

Thanks for everyone's help, and I hope my notes help someone else out!
