You don't have 'bad linux software', or a virus; since you don't like 'wordy' things that 'make you tire', you can go look up why PID's change for yourself.

I never said i don't bother to read and understand. But i rather put the most complicated instruct to try to the most end. Why do i bother to explain myself .. forget it.

Yes, but right now is where is the bug.. need to catch it before make a backup.. else backup also useless if it keeps prompting errors.

The "configuration file not writable" prompt is weird.
I restarted pc after did the "url instruction on single user mode rescue mode":
when i started terminal, it didn't prompts the error anymore..
but half way into using vim, i realized my data file in vim changed to "readonly".
By then i tried to run another instance of terminal, this time it prompted "configuration file not writable" again.

So weird.. what's went wrong..

sudo ?file manager of choice

Set accordingly

If your using a swap file instead of a swap partition, disable the swap file and see if that has anything to do with it.

I don't know what to do.
I did a smartmontools scan on my hdd sdb.
The result shows this caught my eyes:

Code:

  3 Spin_Up_Time            0x0027   100   100   001    Pre-fail  Always       -       2599

Does that means it is failing ?

Is this montool is properly used ? i did the same on my sda, it also indicated spin up time prefail 1458times... But the hdd is fine.. is the result legit ? or maybe use the cmd wrongly ?

If you can get back to the point in post 34, before using vim,
open a terminal run the commands

Code:

free
df -h

use vim
rerun the commands and see if anything changes.

andrewysk,

Sorry to report that your hard drive is failing.

The current pending sector count is 392 instead of zero.

You need to carefully copy the personal data from that drive to an external drive.

One way is to use a live Linux DVD (USB drive) to retrieve personal data:

So,

Code:

is the part that indicating failing harddisk ? not the

Code:

 Spin_Up_Time

?

I have my original endea linux live usb.. i can copy without problem.. as long as i can get it mounted..

Which 2.5form factor hdd should i get ? i think 2T hdd is best price now.. 4T costs 100euro over.. while 2T costs 65euro. I choose 2T, because maybe before i have used up 2T, the hdd would be starting to fail .. so no point for 4T i think.

Is WD hdd is ok quality ? Don't wish to get one lousy hdd and die off soon again. Because the failing hdd was i think around 4 years old.. my other hdd , i have used for data storage for over 8 years.. still no issue noticed..

Seagate is extremely expensive..

Does this tiny amount of cache make any different ? one of the hdd has got drawing on it: desktop icon vs laptop icon.. What's the issue here ? ..oh ya.. form factor is not the same.. i missed that one out.

Those are all good names. Those companies are out to compete. Not selling junk.
I run Kingston and Crucial.

I can't read the spec sheets in german. But please check the specs.
Most of the sellers (Seagate, WD, and others) have two different technologies used for the disks.

I consider the ones using SMR are trash for long term use due to the way the data is "shingled" on the disk and while they work well for a short time as the disk gets more than ~25% full the write speed slows way down. Drives using the CMR writing do not have that problem. I have mostly gone to buying the enterprise drives since a lot of the home use drives use the SMR tech. Enterprise drives cost more but they almost exclusively use the CMR recording technology.

Here are a couple links to data sheets that show how to tell which tech is used here in the US.

This is the data sheet links for seagate 2.5 in form factor and as you can see all of the Barracuda 2.5 drives use SMR recording technology.

Here is the data sheet for the WD Blue 2.5 drives and you can see your chosen model is also SMR while the 500G and smaller drives still use CMR.
According to this guide the second one you linked is also SMR tech.

In my opinion SMR is most useful in a write-once-read-mostly scenario.

While SSDs cost more they do not suffer from the physical limitations of the drive recording tech currently used for the less expensive hard drives. Unfortunately I cannot find any information on HDD drives for laptops that are definitely CMR tech except the smaller ones 500G and less.

This is strangely similar to this:

Funny OP should have a broken USB stick and broken internal hard drive at the same time.

Here is a user benchmark website for HDD. They also benchmark SSD CPU GPU and others.
