I have got MSI MOBO P45 NEO2-FR. I want do RAID but I dont have any idea. I am a jeweller and I have accounts and images in my PC. Daily its upgraded but I am scared that if my hardisk get crashed then all the data will be lost. Also I want to know that if one hardisk is crashed then can I put other hardisk as a primary so that time wont be wasted and once I get second HDD repaired then do I need to format and re-install for mirror image. Please help me. I think I need RAID 0.

If you are scared of losing data, then RAID0 isn't for you. You definitely want to use RAID1. Set the SATA controller to RAID and assign both hard disks to the same RAID1 before installing the OS. If a hard disk fails, you install the replacement disk and let the system rebuild the array. There's no need to reinstall anything unless you use RAID0.

Thank you for your reply but can you tell me the difference between Raid 0 and Raid 1. I dont have idea. And if I use Raid 1 then accroding to u, it will be replaced by second one but what about first hardisk. If I get replacement of 1st hardisk from the vendor (lets take seagate ) then after getting replacement of 1st disk do I need to re-install everything on 1disk or it will take automatically from the second disk.

Let's assume that you install two 500 GB disks. With RAID0, you end up with 1.2 TB of storage and no protection at all. If one disk goes bad, then all data is lost. Therefore you have to reinstall everything and restore your data from the last backup.

With RAID1, you end up with 640 GB because both disks contain exactly the same information. If one disk goes bad, then all data still is on the good disk. You replace the failed disk and the RAID will be rebuilt from the good disk. No installation and no restore are required. I still strongly recommend regular backups because even a RAID1 can fail, particularly if you don't replace a failed disk right away.

Thankx for info. Lets assume I did RAID1 and then suppose there I got a virus in first disk then will the virus get also in second disk. And second how I will get 640 gb since it is a mirror image. I will get only 500GB. Am I correct ?

Since both disks contain the same info, then they will contain the same virus. A good anti-virus program is of the utmost importance if that system connects to the Internet.

My mistake about the disk size. I'm used to 640 GB Western Digital disks, but Seagate disks seem to be 500 GB. You are correct about the 500 GB total storage. If you decide to use Seagate disks, get the newer 7200.12 series.

Thank you so much but in India we dont get 7200.12. I am using 250GB Seagate 7200.10. I have purchased before 2 years. But anyway how to know the cache of HDD. Its 32kb or 8kb or etc. You are really genius. Give me few ideas and tips. Are you using msn , gtalk, etc. So that we can be friend. Hope you wont mind.

Cache size on a disk is more important for marketing than performance. Don't worry about it.

7200.12 is newer and a bit faster. You can check the specs for both at Seagate.

It depends on the OS. You might need a floppy for Windows XP; you don't for Vista.

For Windows XP, a floppy isn't required if you slipstream the Intel Matrix RAID drivers. See http://www.maximumpc.com/article/H [...] stallation for more info.
