My SSD losing data after crash even after saving.

My computer basically can't wake from sleep. Anyhow I have come to the habit of saving certain system information before I sleep the notebook. I hope that it gives me clues as to what the problem is when I find patterns. I have a text file (*.txt) that I timestamp and write data to manually recording such things as memory usage etc. I will then save the file and close it. Then I will sleep the notebook. File is always saved first before sleeping.

Anyway, I find that the data I wrote are lost in the text file after not being able to wake from sleep. It is extremely wierd and doesnt give me a sense of security at all. Basically I open the file, and instead of having text, I get a bunch of 'spaces' in the text file. So yes, the text file has been stretched but instead of having text where it should (with the time stamp and other data recording), I get a bunch of blank spaces.

What the hell is wrong now? This happened twice so far (different occasions).

 

what???/
what does that have to do with ssd...
ask better questions... you might actually get a reply

 

Well excuse me! Of course it might have to do with SSD.

Let me see: my data is stored on a what? SSD. My data was lost after a forced reboot (after having saved the file prior)? Yes the fault most likely lies with the SSD also. Its obvious the data is just gone because the few times it happened I get blank space instead of text where it was surposed to be. Plus all the stories about SSDs not lasting makes you wonder. I have also never experienced this with older HDDs but then again I've never had to hard reboot so many times because my windows cant sleep/hibernate properly like it should.

 

Which SSD? I don't see how this would be happening due to the SSD unless the data is being written to cache and not immediately transferred to flash. (this would be catastrophically bad design).

 

It is a Samsung SSD.

 

what model, if some has the same one, as you they can do a similar test to see if it's just yours or did samsung produce a faulty SSD model?

 

try using sysinternals 'sync' utility or something like it before your sleep.

 

Its the silver metal casing MLC type from samsung. Hmm I am wondering about this cache thing. But shouldnt it be immediate after saving, it will transfer it to 'hard' memory?

I normally will save the text document and then after maybe 30 seconds close the lid to my notebook to sleep it. Is 30s enough for cache to transfer to 'hard' memory?

 

If the only prob you are having is connected to the txt file then it's a good guess that they way you have that process setup is the cause of the problem.

 

you do know that the os has caches, too? and it caches the stuff before even sending to disk. that's why you have to "savely remove hardware" for external harddisks, for example.

do you have caching and advanced caching enabled "on the ssd" (in the device manager). those are os caches, and documented as losing data on crash.

 

my notebook also has problems with sleep. I put it to sleep, then when I wake it up it freezes. I have to hold the power button to turn it off and then back on.

I have a normal HDD. If I save before I sleep it's fine. I mean there is no data loss after the restart.

So it is likely your problem is with the SSD, but it's hard to say for sure.

 

It isn't, by a big chance, the ssd.

uncheck those two checkboxes on your ssd, and it shouldn't happen anymore (but performance drops, maybe much, on writes).

(the second checkmark can delay writes over seconds and minutes btw.)
