So when I put my laptop to sleep and woke it up today I found a file on my D: partition which was a .avi file recorded in Fraps. About two months prior to this I deleted a movie off my hard drive that a friend had given me. This file was titled "DOSBox", implying that it had recorded footage of the DOSBox emulator I have on my laptop, but since it lacked any sort of description, it was seemingly corrupted. So I opened the file out of curiosity in Windows Media Player, and there was no video, only audio. The audio after about 5 minutes I realised was a low quality version of the audio that belonged to the movie I deleted off my hard drive. This scenario is logically impossible, but is it possible there has been some sort of really rare glitch that has occurred, like this file is a gateway to the data that was deleted from my hard drive? The file crashes VLC media player, and according to Windows Media Player it is over 24 hours long. Could someone give a reasonable explanation to what this computer glitch is?

as you know nothing gets permenantley deleted. Could be a weird glitch in your partition caused by putting the computer to sleep.

I cant remember now if its sleep or hybernation but one of those saves the data currently running on your computer to the virtual memory on your harddrive. have you done anything with your virtual memory settings after you deleted that movie?

Nope. I don't dare touch VM management, I just keep it as is. Turns out this 24 hour file only reads up to 1 hour 45 minutes, pretty much just before the movie credits roll.

I had something similar many years ago when sleep mode killed my partition maybe even more than once. I think it has to do with whatever applications running that are put to sleep and saved to virtual memory might cause glitches that can damage your partition tables.

i obstained from using sleep mode ever since.

now that i remember one of such applications that i suspected was a very old game by the name of Carmageddon II.

my advice- dont use sleep mode or hybernation. these can really screw with your harddrive

Wrong! Old file locations commonly get written over, thereby perma deleting the file.

you know what i meant, what if that movie of his was partially written over allowing the broken version to surface or something like that.

Actually, you are wrong. The DoD standard for wiping data completely off a harddrive is to overwrite the sectors 7 times. The common data recovery tools you find online may not recover files that have been overwritten once, but FBI has other tools at their disposal. (this was my college major)


It sounds like data was corrupted in the file, somehow mixing parts of other files. Perhaps the MFT mixed the wrong fragments together. I saw this issue happen recently during my recovery of about 600GB. Not sure if this was what the real issue was, I can only speculate. I did see an entire harddrive have similar issues like this before but determined the drive was in fact damaged.

Ah! I stand corrected and learn something new every day. I'll research that some, sounds interesting.
