I am in big trouble since last few weeks... I am getting 100% disk utilization on my Windows, while I can see no process is significantly using the disk. The issue is faced by many as you can see there are many many threads on this:
This is how it looks like:
100% disk usage
No process is significantly using the disk
Also I created a thread on answers.microsoft.com to ask where to find the registry key to tweak HDD driver as recommended by microsoft's site. But of no use.
I tried, stopping many services, clean boot, running process explorer to checks whats using disk the most, as suggested by many online threads. In fact, I formatted by C: drive and installed clean Windows 10. But issue came back!!!
Let me tell me something about my machine: its Dell XPS 15 L502X. Its 2011 edition. It has 16 GB RAM, quad core i7 2630QM. This machine worked perfect with Windows 7,8 and 10 for so many years but now its failing. As I told above I tried everything thats noted in various sites, but nothing helped.
Now I recalled that few months back I was trying to copy paste some big video file to pendrive and I was getting another famous error "Cannot read from source file issue". I didnt paid much attention to it. Left those video files as is. I remember I tried running chkdsk
with no success. Now I started feeling that the issue was aggravated. I felt this must be due to bad sectors. So I cut pasted all files in the drives to external hard disk using TeraCopy software. It gives list of files that failed to copy. So I deleted those files when TeraCopy was not able to move them and then recovered those files using EASEUS recovery tool. Then I hard formatted (not quick format) thinking that it will fix bad sectors. This worked for E:
drive.
But while doing same for F:
drive, it got all screwed. First while recovering files, I was getting blue screen of death. So I left those files unrecovered and went on to hard format the drive. But now after almost 5 hours its barely 30% done.
One more observation, many times after random killing of processes (mostly onedrive which had folder in F: drive), my disk utility used to come to normal after few minutes.
Q1. So should I conclude its hard disk which is culprit here?
Q2. Will this formatting of F:
drive ever complete?
Q3. If completed will my machine be fixed, that is will my machine be free from 100% disk utilization?
Q4. Will my hard disk be safe to use in future for no data loss...
Q5. Should I buy new hard disk?
Q6. Does hard formatting fix bad sectors at all?
Q7. Should I do the same for C:
drive too? While installing Windows I did quick format, not hard format.
Sorry for so many questions...but I have wasted many weeks on this. And no thread online is of help to me.
F:
for some more hours?
