Before I post the rest of my info, here is exactly what happened leading up to this... My computer froze and I restarted the computer. It ran for a few more minutes and then it froze again. Then the as it was restarting the cooling fan failed. I restarted the computer and it tried to load a few more times but would not completely load the OS and would freeze. Then each other time of restarting it had trouble recognizing my DVD-R/RW drive and HDD. I checked the BIOS and trying disable then enable the RAID function in the BIOS. Also changing the Boot order to DVD-R/RW first then HDD then switching it back to no luck. I double checked the connection to the DVD-R/RW drive and HDD. My computer has a diagnostic function, so at start up, I ran the diagnostics and my processor and 8 GB of ram is running correctly. When I started searching online I found a site where the exact same chain of events happened to someone else. Here is the site with the thread. (As soon as I post 5 post I will post it...) Try googling "Roasted RAID Controller" - that is the title. Here is the link... http://www.pcmech.com/forum/computer...ontroller.html Here is the first link about someone having the same problem as me. Fortunately I have another cooler fan that works and have plugged it in my comp and it runs now, also if I let the computer sit the drive is recognizable but will not boot. I have an older computer I am using with a usb connector that has a power supply and multiconnector that can have sata, ide connected. I am using this to hook up my SATA drive to my old computer. Fortunately it recognizes the main partition with my data, and the HP partition that has the system restore and recovery partition on it. I have downloaded the RAID Restore program but I am taking my time with it, unfortunately if you use a RAID probe it cost money and the program will only diagnose if it can be restored. I found another thread on another forum where someone had the same problem and it turned out it was a faulty power connector. (Again, I'll post the link later.) Or google "sata drives not recognized after disassembly reassembly" and choose the first link. In the archive it is number 8205. Here is the link... http://www.techsupportforum.com/hard...eassembly.html If it turns out to be the RAID array is there a way I can repair it without using the RAID Restore program, a manually way of repairing it. Is there a way I can replace some files on the drive to restore the RAID. Does windows 7 have a restore disk I can use, or has anyone created a disk to restore this problem. I had a problem with a computer with XP and someone had taken the recovery part of an XP Install CD an posted how to manually created a way to repair the MBR which I used and the computer booted up. Unfortunately PCs come with restore partitions than CDs when buying computers from places like Best Buy. Also I searched out the repair features in Windows 7 and they say there is a start up repair function. Is there a way to use this on the drive without booting into Windows 7 which I can't do.
