HDD stuck in raid array

post #1 of 4
Thread Starter 
I have a Seagate ST3160212SCE 160GB hdd that was part of a raid array i dismantled the array and set up a new one with different drives and for some reason this drive still thinks it is a part of the old array. when i go and delete the array that it belongs too it says completed successfully and you restart and back to square one try to remove the drive from the array and nothing. i turn off raid and the drive shows up and you can create a partition but when it goes to format it says cannot access disk. I'm stuck please help.

Pull the drive from the current system and put it in another system that has Windows 7, XP, Vista - whatever. Using Disk Management Console, initialize the disk and define the file system whether NTFS or FAT or whatever you plan on using. Then, when the disk is inserted in the system you are using it in, it will register correctly. This is because the array has to be deleted from the RAID BIOS or Option ROM on a system before the RAID array is dismantled. If you fail to do so, the disk will appear to still be a part of an array and will be inaccessible in Windows. You must first initialize the disk and then define the file system type for the drive to correct this issue. Why, well when two drives are in a RAID array, the logical disk that is created is defined both in the RAID BIOS and the MBR on the logical disk that you created by linking two drives in a RAID array. Even though you can remove the drives physically from the array, they will still have that code that says - hey where's my other drive for my logical disk array? This is why you are having this problem. If you need help with this let me know. Should be an easy fix if you follow the above.

Ok well I have an external hdd case hooked up to my laptop and I can pull it up but when I try to format the new partition in windows it says cannot access disk. does it have to be hooked up to an onboard sata controller if so I have another system that doesn't have any drives on it. Unfortunately it means no OS

Did you lock the array when you had it previously RAIDed? If so then you will have to use HDAT or HDDunlock to unlock the drive. You may want to use a series of tools from the Hiren's Boot CD. You need to use SeaTools from this disk to analyze the HDD and make sure that nothing happened to it since you pulled it from the array. It may have received shock damage to excess Gs or had a head failure or something. Also, if the disk cannot be accessed, you may have a bad HDD.
