I almost couldn`t believe it! You made it - thank you very much!

You`r the man! very cool.
To the last moments, I was still expecting some rollback... but this time it did`t.

Hi,

You're welcome. Glad to hear the problem has been resolved, this was an odd one and we had to deal with different issues...

 

[Bobbby]

Do you have an idea what might have caused the problems?

 

[Maxstar]

There are several reasons for these kind of corruptions, like; power cycle failures, forced shutdowns, system crashes, harddrive or memory corruptions. Allthough it is difficult to ascertain what the exact cause was. And in this case there were multiple issues and that makes it even more difficult to explain the root cause.
