CHKDSK on SSD

Computer0304 · Feb 17, 2015

My laptop with a SSD (different from one in my system specs) recently froze up so I had to force shutdown it. There seems to be no corruption, but can I run chkdsk to make sure it is okay?

There would be no problem.
Same question was asked and answered by our own Brink, in the past

I have personally run Chkdsk on my ssd's with no problems.

Jack, what did you get as a result.

Brink · Feb 17, 2015

Running chkdsk on an SSD is fine.

You just don't want to defrag a SSD. Instead, you would want to TRIM a SSD.

Wait, but do ssds even get bad sectors? This is how the freeze happened, I was trying to open Windows Explorer, and it didn't stop loading. Nothing else was clickable but the cursor was movable, and stayed as the loading cursor. So I tried to force sleep by closing the lid, but it didn't sleep. So I opened it again and the screen was black with the power button still on. I tried pressing the power button to see what happens but it stayed black. So I just waited for the disk activity to stop and held the power button to force it off. There is no visible signs of corruption though in my personal files. But it did start up slower but this must be because Windows was not able to do hybrid boot since the drivers and the kernel was not saved to disk.

If you drop power in the middle of a write to disk (SSD) operation, you can still get a corrupted file/folder.

Well, so are you saying I should run chkdsk?

richc46 · Feb 19, 2015

Yes, run it. Remember on any hard drive it is not wise to run it too often. Good to run if you have performance problems or after a lot of downloads.

Computer0304 · Feb 19, 2015

How come it is bad to run it often? Just wondering because on my old computer, I ran it any time I felt like the computer was running slow. That was about once a week. Sometimes less often.

richc46 · Feb 19, 2015

Chkdsk wears out the hard drive just like any other drive activity; maybe just a bit more. Basically it can be used safely, but as with any hard drive use it will eventually cause the drive to fail.

Computer0304 · Feb 19, 2015

Oh, but my old computer should be fine?

richc46 · Feb 19, 2015

Hard drives have an average life of about 6 or 7 years, depending on usage. The more you use it the shorter it will last, it is the same with chkdsk. It is OK to use, but just do not over do it. I do mine when there are performance problems or once a month.

Computer0304 · Feb 19, 2015

Well since it still works, I guess it is fine. Is running it about once every month fine for a ssd and a HDD?

richc46 · Feb 19, 2015

I do it about once a month, and I do not have any problems. My hard drive is almost 6 years old and running fine. That being said I do not have a ssd, but as far as I know there is no difference in this area.

Computer0304 · Feb 19, 2015

Well since ssds have a limited amount of read/write cycles, I would assume you would have to run it a little less often just to be safe.

richc46 · Feb 19, 2015

I would agree with that

Ztruker · Feb 21, 2015

The concern is the number of writes that can be done to a SSD. It's really unfounded, especially with newer SSD drives. They have an expected life many times that of the older magnetic platter (spinners some call them) drives.

I don't remember the exact wording but as I remember their where no problems found.

I didn't even want to run Check Disk. It just popped up out of no where like had scheduled it. Which I had not done. It did take me a while to figure out why.

I left a DVD movie in the player that is set to boot before my system SSD.
So Windows 7 figured I needed a Check Disk done.

I removed the DVD rebooted and let the Check Disk complete and all is well.

There is no need to worry about chkdsk, because while it does lots of reading, it hardly writes anything to disk (unless it finds errors, and even then it's very limited). What it does is analyzing the whole filesystem for consistency of its internal data structures, which does reads many sectors but not writes.

Defragging on the ohter hand does tons of both reading and writting, that's why people fears them on SSDs. Also, those disks don't profit from all the actions of defrag as mechanical disks do, rendering it as a partially useless task.
