I have a new Client running a Dell server with a Perc6 Controller. The are also running a SQL Server 2008. I noticed today that there are around 20 .chk files on the root C: drive with an associated .Txt ; I have seen Chkdsk create these file with a prefix of filexx but here, they are random number prefix. I also noticed that around 20 of these files types are also in the recycle bin which is a real mystery because nobody deleted them. Does this mean I may have to replace one of the Raid Hard disks if I can figure out which one is bad first or is some kind of normal behavior from the sequel server.
