Strange behavior on an SSD. Windows 7 Pro.

Hello,

Something I have not seen before. Using a database for about 12 years now. Not once has this happened where the client application became corrupt. The client directory is C:\PROGRAM FILES\CMR1246\CMR1246.exe. There is a shortcut to this file on the desktop. All of sudden CMR1246.EXE says the application cannot be found. I go to the PROGRAM FILES directory, look for the CMR1246 directory and it is not there. Instead there is a directory called  C:\10212\DATA\CMR1246.EXE.

WTF?

Anyway, did a chkdsk. No errors found.

Have never had this happen before on any HD in twelve years. Now, using SSD drives...error shows up. A coincidence?

Thx

The folder structure changed. I do not think an SSD error would cause a nice neat folder change like this. I don't you database or why it might have changed folder locations, but I do not think an SSD would cause this.

Might the database backup have caused this for some reason?

Hello John,
Yes...strange. It was the client software that got corrupted, different from the server software. The server software and the database get's backed up. I can see the user's log-in getting corrupted somehow if he was logged in the database and the backup software messed up. But a change to the client file structure change like that? In Windows 7.  Is it an SSD cache issue with Windows 7? I do not know. Has never happened before.
Thanks

I agree with John => it's indeed a strange issue, but it is almost certainly NOT due to the SSD.

An SSD is just a disk ... it happens to be a fast one; but that's all it is.   Whatever caused this would have caused the same thing on a traditional rotating platter disk;  a RAID array; or whatever storage media you happened to be using.

Have you checked the system for viruses and rootkits?
There are two possible explainings:
1)Third program did change/corrupt the program directory
2)The user itself tried to remove and then install this program

Look into Events in the time frame when this happened.

First: the problem is NOT the SSD.
Second: did you clone an HD to the SSD? Maybe the cloning program has problems (in that case it is the first time i hear something like that)

The problem persists if you reinstall the program and restore the DB?

Checked for viruses/rootkits.  No entries in  the event viewer as a problem happening. No, the drive was not cloned. No Raid array, the SSD is the boot drive in a Windows 7 computer. The drive is set at its fastest speed, have the PC on a UPS.

Thanks.

Did this happen only one time? I still assume it could happen via the intervention of the user.

It seems to me just a bad copy/restore of the program/database.
Just try to reinstall/restore and let us know what happens.
