I've Googled the heck out of this and I'm getting nowhere. I have little hope, but thought I'd mention it in case anybody has inspiration. Windows 10 Professional (or whatever its called)/ Bog standard, 5xdisk, 16GB RAM PC - Every now and again disk usage goes to 100% and stays there for 5 minutes and then inexplicably drops again.
- Its usually C:, but has on occasions been D:
- The CPU and memory usage remain normal (low)
- No virus or malware
- The process using the disk is "System and compressed memory", specifically ntoskrnl.exe. Excessive CPU usage reports have been made, but little or nothing on disk usage.
- 75% of the time it happens when a video is running, but 25% of the time there isn't.
- When this occurs virtually nothing can be used that needs disk access
- Page files / swap files all normal and standard
- Every solution I can find on the internet I have tried. Feel free to point them out again though in case I missed something
I can find no consistency, I cannot recreate the issue at will.

Mmm. Computer just died. I feel that the disk itself may have been the problem and that it has now died.
Deader than a dead thing being dead.
Bugger.

Last backup on the system disk 3 months ago. It rarely changes.
Forgot I moved a data directory there just temporarily and have been using it for two months.(new and edited files)

I'd say your hard drive is failing. OH! I was right Still, as you are always harping on at us about it, I'm confident you have an up to date, current and accurate back up. OH! |

Mmm, there is clearly more to it though, because sometimes it was a different disk.
Still wading through the crap seeing where I can get to.

Zero,
I have instaĺled W10 on a spare drive, moved existing sys disk to d: and booted.
I can see the ex sys$disk and access some of it. But random, yet consistently the same, areas cause the thing to hang. Copying files off mostly fails with a "cyclic data check" error.
I have run chkdsk a number of times. It ran very slowly in the beginning, it still isn't quick but its better. It solves different issues each run, and gradually less issues.
Though its not making disk access and better as far as I can see.
Does a wild guess say its worth continuing or I'm wasting my time?

Sounds like the Boot sector, FAT are ok but the data is disappearing, probably a head / disk interface issue. (if its a traditional disk. Save what data you can and dump it. |

As Zero says, try and get as much off as you can - you know the directory of interest. Sods law is it's going to include some of those files! How important are they - could be costly service to get the data back... very costly.
And then upgrade the system drive to an SSD.

At this moment would you care to guess which 75mb directory on this 2tb disk that I cannot get to??

The disk is knackered. I have about 75mb of files on there which are not backed up.
I never keep anything on there normally and I put this one directory there temporarily and got interrupted and forgot.
I am hoping I can recover it later. But first thing is to get the machine back running.

Reinstalled W10 on a new disk. Attached the duff sys$disk as a secondary volume.
Ran chkdsk and it was just finding more and more errors. It seemed to be fixing them, but stuff wasn't getting any better.
About 75mb is desperate to get, but there's about 100GB my life would be easier with rather than without. Just to save hunting back through loads of backups and various copies to reassemble the final updated set.
Eventually I used a couple of free chkdsk alternatives, the command line and robocopy. It is moving, ignoring errors, various data files and continuing no matter what. I reckon its getting about 90mb out of every 100mb copied to another disk. Its still running and I shall do nothing to upset it. We shall see what we manage to retrieve.
Much of this is my own stupid fault. I had been meaning to rationalise my copies/backups, to do a clean install of W10, and to reorganise my data storage. Until 12 months ago it was all good, but I've been lax, and as other disks have been getting full, I have been using the sys$disk more than I should have been.
Ironically this is a long weekend and I would probably have done it tomorrow.

I'd forget to do backups on a regular basis. The Mac used to have an automatic Time Machine backup but that's not setup at the moment. But the machine automatically backs up to the cloud (Google Cloud Storage) daily anything that matters - so documents, photos, music, etc. Music is also sync'd with Google Play Music.
I think an automatic backup plus extra manual ones are worthwhile.
Best of luck recovering this data!

Finally!!!
Back on line, data recovered and fully backed up.
The data transfer rate was abysmal, sometimes so slow I wasn't sure it was still making progress. If I had to reboot, then it was taking 30 minutes just to mount the disk.
Got the 75mb back, lost a few bits and pieces, nothing important lost I don't think. In fact I've made significant gains I think in now having a clean install. Andbecause of the transfer rates I got rid of loads of old crap I really didn't need any more rather than transferring it.
What an utter waste of a week.
Still, all clean and whizzy-whizzy now.
