I have a strange problem with my computer. When i try to create a file (anywhere on my hard disk):

  1. File is created
  2. I can see the file or rename it
  3. I turned off my computer and turn it on again
  4. The file is not there and deleted

When i try to remove an existing file from my computer (anywhere on my hard disk):

  1. I can delete the file successfully
  2. I turned off my computer and turn it on again
  3. The file is still there

I can not even uninstall any software from my computer or install new software on it. Also i am using Mozilla Thunderbird to manage my emails and my email disappear every time i shut down my computer.

At all, any change to my hard disk is ignored after shut down!!! Please help me.

My computer is:

  • Type: Dell Vostro 1500 Laptop
  • OS: Windows 8 Enterprise
  • H.D.D: Solid State Drive (SSD)

First guess is a virus. Run a couple of deep scans with various anti-virus software. I use Microsoft Security Essentials and Malewarebytes. – Xavierjazz Feb 22 '13 at 18:21
Do you use any 'deep freeze' like software? – Hennes Feb 22 '13 at 18:22
I was scanned my computer with Microsoft Security Essentials and there is no virus. And I don't have any 'deep freeze' like software. – S.Yavari Feb 22 '13 at 18:40
Some sort of bug in the disk cache. Basically the shutdown logic isn't doing it's job and nothing gets flushed. (Keep in mind that the system avoids writing intermediate results to the SSD drive to not "wear it out".) This may be exacerbated by a journalling mechanism that restores the old data when it's not told the "transaction" is complete. – Daniel R Hicks Feb 22 '13 at 19:36
I’m curious to learn what would happen if you create hundreds or thousands of files, preferably largish ones (presumably using some sort of script), then go get a cup of coffee (or maybe lunch and/or dinner), and then come back and shutdown the computer (I hope you are shutting the machine down cleanly and not just “turning it off”) and reboot. If some of the files are there, then it might be a bug in the disk cache. If none of them are there, then maybe you have a virus. Or maybe the OS believes that you are a virus, and is rolling back the “damage” that you are causing. – Scott Feb 22 '13 at 21:08
