CHKDSK is finding 1047300 KB of bad sectors on the E drive (Information Store location) whenever I run a CHKDSK /f /r on my Exchange VM. It has a Windows Server 2003 Standard SP2 OS and Exchange 2003 SP2 loaded on it. About two weeks ago we had an issue where users were unable to send/receive emails. The Information Store was unmounted for some reason. Event logs do not show any smoking gun. Anyways we ran a CHDKS /f /r and it added 261,825 bad clusters to the Bad Clusters file. It also showed errors stating "correcting errors in the Volume Bitmap" and "the second NTFS boot sector was unwritable". After a reboot users were then able to send/receive. However ever since this incident we have been unable to perform any sort of backup of the e drive using our block level backup system. (Shadow Protect)
Since the initial failure I have run CHKDSK /f /r a few more time and the results always shows "Windows has checked the file system and found no problems". However, the results also show that there are 1047300 KB in bad sectors. Should I be concerned about this??? Thanks.
