Windows 7: SSD Errors, Low Level Format Required?

I thought about the 3340KB in bad sectors. I also thought about the two jpg files which lehrenus2000 was not able to copy. These could have been the files in the bad sectors. Was Lehrenus able to copy the files after the 12 hour checkdisk run? Only Lehrenus can tell.

Now, Megahertz07's concerns are valid. In a hdd if bad sectors show up we indeed recommend to keep a watch on the HDD. If the bad sector count keeps increasing, then it is an alarm signal.

Lehrenus: "If this was occurring on a HDD partition, I'd assume that it had defective Blocks/Sectors and the HDD would need to replaced."
"Is this the start of an avalanche of errors (just like a HDD)?"
"The SSD is 3-4 years old, so it may be vulnerable to the "power loss damage" issue.
We had several power dropouts last month and on at least one of those occasions, I had left the LM17 VM running. "

Does what applies to a HDD also apply to a SSD? Hey, this is electronics. Given the power drop outs mentioned by lehrenus, that could have caused the damage to a few sectors. If it is so, I don't see an avalanche effect as we are afraid of in the case of HDDs. Bad sectors in an SSD cannot and need not be equated with bad sectors in a HDD.

Did lehrenus lose some files in the bad sectors? Or was windows able to retrieve the files in the bad sectors, before marking those as Bad?

Whatever, lehrenus need not relate an SSD to the HDD and live in fear.Nevertheless, given that our understanding of SSDs is still sketchy, it will be prudent to keep a watch on the bad sector count atleast for a reasonable time period. Whatever has been stated above is still a reasonable speculation .

Note: Believe me, I started writing this in my last post itself but on second thoughts deleted it. I did not want to sound an alarm. Also leherenus has been reasoning so well throughout this thread, I did not feel that was necessary.

Finally Dead

And you have 835 bad clusters.
I would replace the SSD drive.
I was hoping that it might last for a month, so that I could save up some cash for a new one.

Thanks for your tip list.

I move the Page File off of an SSD when I can (one of my friends "pays me out" for doing that).
My main PC has an SSD + 3 HDDs.
My laptop and other Desktop only have a single SSDs (no HDDs).

Before I tried "CHKDSK /R", I deleted the 2 jpgs (from "inside" the VM) and attempted to copy the VM.
Deleting those files didn't fix the issue.

I guess we won't discover the answer to that question using my SSD.

It's possible that the Bad Sectors and subsequent Controller failure were unrelated, but it seems suspicious.

It seems that as soon as you notice any errors on an SSD, it will be dead in a few days (unlike a HDD).

I checked my records, the SSD was 3 years old.
I've only had one internal HDD fail after 2 years + 10 months use.

I bought an external HDD that was broken, before I opened the package.
I returned it to the store and the replacement is still running.

It seems SSDs do everything faster including self-destruct.
I was able to run the operating systems and VMs for ~1 day after the repair.

I wonder if VMs somehow cause additional "wear & tear" on SSDs.

The SSD died whilst I was watching it.
As I was copying some files from a VM, I noticed that the transfer speed steadily decreased until it was running at ~2 MB/s.
When I shutdown the VM, I noticed that W7 was lagging badly.
I've seen that happen when there are memory/storage issues.

I booted in to LM18 and it was running normally.
When I tried to reboot into W7, the SSD died totally (no longer appeared in the BIOS).

The only good thing was the replacement SSD was on special, so I "saved" $30.

That is very unfortunate. It then turns out that the creation of bad sectors is not attributable or related to the power dropouts but the start of the dreaded selfdestructive process in SSDs.

That seems to be true in this case.

Thanks for everyone's input.
