I have been having this problem with my pc. If I try to install anything, like DirectX or something that just needs to use an installer, my HDD will just randomly start to fill its full 3 TB and then slowly deplete back down to the normal size of what I had downloaded, sometimes doing it in a loop until the install finishes.

I have did everything with chkdisk, seatools disk check and more, all say that there is no problem with the drive itself. I have changed out the SATA cable and the problem still happens to me.

I can't find anything else about this problem, is it because of my bios settings or something along those lines, or is it actually a bad drive and checking the disk itself won't show anything.

I'm running on a clean install of Windows 7 64-Bit Ultimate, Here are my specs:

CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
Ram: 8 GB
GPU: NVIDIA GeForce GT 640
HDD: Seagate Desktop HDD ST3000DM001 3TB

If anyone can help me with this problem please, as this is just getting annoying for me. I can still use my pc and do other things, but installing anything is just a pain at this point.

Normal during install:


Not Normal:

  1. Full hard drive

    Full hard drive

  2. Resource Monitor

  3. Resource Monitor Again

  4. CPU Kernel Time (In Red) Goes nuts

    CPU Kernel Time (In Red) Goes nuts

  5. Resource Monitor (Write)

Every time this happens, the kernel CPU % starts to exactly match the normal CPU usage, and the problem won't end until the kernel CPU usage decides to go down.

    Open Resource Monitor and check what Windows reports under disk activity (sorted on Total (B/sec) while you install something. Take a screenshot like this one i.stack.imgur.com/azK7M.jpg and it to your post. – HoD Feb 16 '18 at 7:56

  • Adding to @HoD's comment, sort the view by Write (B/sec) and also pay attention to the path of the files being modified. You could also run a GUI disk space display tool during the install...more than likely all this data is confined to a single folder structure that will stick out like a sore thumb. Wild guess here, but perhaps the installs depend on some other framework that is trying to perform a jit assembly and is stuck in loop that's generating lots of temp files. – I say Reinstate Monica Feb 16 '18 at 14:08
  • @TwistyImpersonator I have added the images for write – Kaydax Feb 16 '18 at 21:18

Looks like something preallocates all space when you attempt an installation.

You should:

  • Run a SFC /scannow (from command prompt) to check windows files integrity

  • Update windows installer package and/or try Windows Installer Cleanup Utility

  • Clean your junk files from all Windows known locations.

  • I have tried this out, now it is time to test to see if it fixed up anything – Kaydax Feb 16 '18 at 9:25
  • None of this helped. Still getting the same problem – Kaydax Feb 16 '18 at 10:01
  • Run a disk check and also clean C:\Windows\Installer location if you didn't already. – Overmind Feb 16 '18 at 13:04
  • An install pre-allocating over a TB of storage? That's not right...Why would the applications the OP is installing do that? – I say Reinstate Monica Feb 16 '18 at 14:02
  • Because it's Windows. – Overmind Feb 19 '18 at 13:15
