Believe it or not a RAID 5 failure after a BIOS update is not uncommon. If you have updated BIOS and are now experiencing problems with your RAID 5 array, this article is for you.
Most the time after a BIOS update your system will give you an error that your array is missing, this is because your settings have been reset to default, whether that is ACHI, ATA SATA mode and therefore it doesn’t recognize your RAID array.
It is important to note that not only are the data AND the drives are neither corrupted nor damaged. It is simply just a system error because the BIOS update reset your settings. Please do not attempt to re-create your RAID 5 array or you may potentially overwrite you precious data.
Before doing a BIOS update, you should disconnect your RAID and conduct the update and plug it back in. If it is too late for that, the very first thing you want to do is backup your data to an external hard drive before doing anything to your array configuration. If you are unable to perform a backup, you should hire a professional to fix your RAID 5, hands down. Don’t attempt it unless you are willing to sacrifice your data. If you would like to recover it yourself, please follow these steps.
• Boot Windows in ACHI mode
• Hit the windows key + R to open the run dialog box and type msconfig and click go
• When offered a boot option, choose “safe boot” and click ok.
• Your system will now reboot and windows will load in “safe mode”
• You should now be able to load the RAID driver under the device manager
• Reopen msconfig, uncheck safe boot and go to the general tab and click “normal startup”
• Restart your computer and it should now boot in normal mode with the RAID driver loaded.
If you are mission critical, need your data and don’t want to attempt to recover your RAID 5 yourself, relax, it can be saved.
RAID is an awesome system for increasing the speed and availability of data as it offers more data protection than non-RAID disk systems. However, they are extremely complex and as a result gambling with your data is a bad idea.
Do a search online for a recognized RAID 5 recovery specialist, like Hard Drive Recovery Group; if you cannot find someone there are many companies that can quickly fix your array, even if you have to send it to them at a different location. (more…)
