I have this ST315005 41AS hard drive for about a year. I use it as my 2nd drive for storage only. There is about 195 gb stuff on it. My C drive is a WD 1.5TB. All software are run from there. Oh, My Document is targeted to a folder in my 2nd drive. OS is Win 7 64bit ultimate. Since yesterday, I started to get this message saying that my 2nd drive has problem and ask me to back up as it is going to fail imminently. I have managed to back up everything today. I have already deleted the partition and created a new one. Formatted it and put back the files. While this was being done, the same message shows up again. This make me worried. I haven't run the "Check" yet. Any suggestion before I do it? Many thanks in advance.
