I have been running windows software RAID 1 (mirror) on Windows 2008 R2 for a while and recently I experienced something very odd, hope someone can help explaining and share your view.
Yesterday (Mar 14) my Windows 2008 R2 server just crashed and rebooted, and before it entered windows it said "bad sector" detected and it had to do some mapping/marking on the drive. After 5-10 min, it started Windows and the mirror drive was offline. Okay, but when I looked at the Event Log and the file system, I was shocked to see all the data was gone from Jan 29 - Mar 13. There wasn't ANYTHING in the event log for that period, it was so wierd. In the file folders, I could see data only prior to Jan 29, not anything after. Luckily I have Backupexec to restore the data.
It seemed like the last "good recovery point" was in Jan 29... how does this work?? why would I lost all the data from that date and on? I assumed if mirror drive failed, the 1st drive should have captured all the data up till yesterday. I am confused.
