Every Saturday windows writes a lot to the SSD.

Hi.

I have noticed that windows 7 writes about 2.5gb more to the disk on Saturdays than other days.

Here is a screeenshot of SSD life:


I have done these tweaks:
1: Indexing, Readyboost, Readyboot, Defrag, Hibernate, Superfetch, Prefetch, are turned off.
2: The temp folder for IE9 is on the HDD.
3: The Page File is set to 8gb on the HDD and turned off on the SSD.

I have monitored the writes for a few weeks and this always happens on Saturdays.

Does anyone know what causes this issue?

Thanks in advance.

 

Open task scheduler and see if anything is set for that time slot.

 

Thanks for the fast reply!

I opened task scheduler and it shows that no tasks are scheduled



The screenshot is in Swedish (because I can't change the language), but it shows that 0 tasks has been launched automatically by the scheduler.

 

I understand what the screen shot indicates .. Have you ruled out any type of malware, or could your antivirus or Malware program be doing a scan ?

 

I have Panda Cloud antivirus. It does not have a scheduled time to scan.

I ran a scan with Panda Cloud and malwarebytes after taking the screenshot. The computer is clean.

 

See -- How to hunt down more applications that frequently write to your disk
here How to Maximize the Life of Your SSD

 

The easiest and probably also the most time-consuming way to find out what exactly writes to your SSD is to use the resource monitor in your task manager. Leave it open and check your disk activity every few minutes to see if there is anything large written to your SSD, of course you will need to do this on Saturday.

 

Thanks for the link.

I followed all the steps in the guide. I will monitor the disk like a hawk next saturday.

I will do that next Saturday and keep you guys updated.

 

I agree w/much of the advice given in the Lifehacker article, but I wouldn't be so concerned about your SSD's life to move the page file to your HDD, unless you're doing tons of other writes daily.

same for the temporary internet files. the faster it can access those small files in there, the better.

in essence, leave the system as it was after installation. that's how it's designed to be, and that's what the ssd is built for.

 

How about restore points?

 

I disabled system restore.

 

Change the date temporarily to next Saturday(2/18/12), then reboot. That way you can test/retest things without having to wait many days And, you can test everyday; multiple times if you've determined the time during the day when this happens and fiddle around with the hourly/minute clock.

If stuff happens, then it -is- date dependent. If nothing happens, then you may be encountering a countdown timer that is not date dependent, but just happens to countdown an interval that arrives on the next saturday.

 

Thanks for the tip

I have tried setting time in 10-minute increments. It does not seem to trigger the writing.

The writing must be countdown triggered as setting the time did not have any effect

I will keep you all updated on Saturday. I will set the time one day ahead to make sure that it is countdown triggered.

 

Update

Today I caugh the process in action (although it is Friday).

Here is a screenshot:


Does anyone know what this is?

I hope this will help.

Have a nice weekend.
