How to do Windows 7 data recovery if hardware incompatibility issue arises



Microsoft windows 7 being the latest is the most advanced operating system that includes advanced security features and several performance improvements. Upgrading to such OS is always desired by users and is definitely a nice idea till it processes without any issue, still problems exist. One major issue is that of hardware incompatibility and if happens so there is high probability for the data to be lost and windows 7 data recovery needs to be done using the most efficient technique that too using application that complies with it.



In a particular case when you install Microsoft windows on NVIDIA nForce4/3/2 that uses a RAID array with RAID OROM (option read only memory) later than 5.6, RAID array might get damaged. In such a situation the drive data becomes completely inaccessible causing loss of important data. This is the time when you need to work out to find the cause of the error as well as restore the data by fixing it out.

The cause behind such an issue is difference in PCI sub class of RAID array controller to that of class code of raid controller that Microsoft IDE (integrated drive electronics) drive uses for drive accessing. Instead NVIDIA RAID configuration uses fundamental NVIDIA SATA which when overwritten by installation of Windows 7 leads to loss of data.

However, there are few steps which when followed before installation is done can prevent data loss, firstly by making backup of data and checking if the class code of RAID controller.

It is done as follows –
From start- control panel- device manager
Select disk drives , right click SATA RAID controller
In properties, click on details tab and then select hardware ids from property list
Verify the ids if its –CC0104 no problem would arise in installing windows
In other cases i.e. when it is CC0101 or other OROM needs to be updated by BIOS updation

Get Software         


But, if you have already faced this problem and don’t have a backup also, then to get back access and recover data you may use windows 7 data recovery software. It is one of the most powerful program with highly accomplished feature and capability to restore data in all cases like corruption, format and deletion. It also supports Windows Vista, XP, 2003 and 2000 and FAT and NTFS file system used.
