Just booted up my computer this morning and got the clicking and spin up and down sounds and the computer wouldn't load up and I kept restarting the computer and trying different things and it just stopped doing it and booted up perfectly fine. My hard drive is a Western Digital and when it was acting strange it said on the post screen that it was a WDC HAWK 10.0 and some other numbers and it never said that before. What could this mean? Why would the hard drive do this and post a weird model name and then go back to the right name and work fine like no issues at all? Event viewer gives no errors and disk check made some corrections to the file system and that's about it. Is the hard drive failing?
