Windows 10: What's the use of disk 0

I've searched for so long but still haven't got an answer, my disk 0 has 1tb unallocated space but I can't use it, I tried to new simple volume it but it was just grey, I know nothing about computers but I'm supposed to have 1tb but only have 118gb usable storage, what's the unallocated for??

switch disk numbers: I want Disk 0 to be Disk 1 and Disk 1 to be Disk 0

Hi, My computer contained a normal HDD hard drive. I recently upgraded to a SSD. The original HDD is Disk 0 and the new SSD is Disk 1. The windows OS is on Disk 1. I want to dual boot my system with Windows and Ubuntu with both OS being on the SSD. Since
the SSD is Disk 1 the Ubuntu install goes directly to Disk 0 because Disk 0 is first on the list. How can I switch the two Disks so my SSD drive is Disk 0? Thanks.

 

Unsupported Disk Layout for UEFI firmware

Step #5 - in the command window that opens type:

diskpart
list disk
select disk 0 <- make sure disk 0 is the hard drive in question!
clean <- this will erase the disk selected above - make sure disk 0 is the hard drive you want!
convert gpt
exit
exit

 

Disk Active time 100% Disk transfer rate 0

This is a problem I've seen reported countless times, on Microsoft support sites and elsewhere. Task Manager shows "Disk Active time 100% Disk transfer rate 0", and everything that's running on the computer freezes, although sometimes you can switch windows,
or even perform some operations within a window, but other times
everything freezes, including the mouse pointer. It usually lasts for 30 or 60 seconds, but sometimes it goes on for several minutes. Then it stops and everything goes back to normal, including Disk active time and Disk transfer rate.

It happens regardless of the apps I'm running or the activities I'm doing. I've even seen it happen with no user apps running at all - no browser, no file manager, nothing but background stuff. It happens every single day, regardless of whether there has
been a Windows update installed.

Microsoft gave me a fix for this problem a week ago, but it didn't work. Here are the steps I followed:

at admin command line prompt:

• Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
• dism /online /cleanup-image /restorehealth
• reboot
• find driver file for Intel(R) 9 Series Chipset Family SATA AHCI Controller
  • C:\WINDOWS\system32\DRIVERS\iaStorA.sys
• Details tab from Properties window for controller
  • Device instance path:
    • PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA
• find registry key for disk controller
  • Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_8086&DEV_9C83&SUBSYS_06B01028&REV_03\3&11583659&0&FA\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties
  • change MSISupported from 1 to 0
• reboot

The instructions I was given include this for Step 4: If you see “StorAHCI.sys” in the list, you are running the inbox driver. But my driver is iaStorA.sys, so maybe this
fix doesn't even apply to me.

After doing all of the above, twice, I still have the problem. I've seen this now over a period of about three years, on two completely different laptops, one a Toshiba running Windows 8.1 and currently on a Dell running Windows 10. I also have a Thinkpad
for work that runs W7, and I've never seen it happen on that machine. It got so bad on the Toshiba that I ended up discarding it, after spending countless hours trying to fix it.

I've also tried all the fixes I've found on the web, e.g. disable superfetch, disable BITS, add write permissions to Skype and the browser. Nothing I've found so far has helped. I also reverted Windows back to build 1703. That didn't help either.
