Please help me to solve this data storage trouble?

You have two questions that puzzle me. A RAID 0 setup where you merely "stripe" one file across two drives is typically used by an IT manager where extremely high read/write access is required and is almost always implemented as part of a network with with an extremely stringent backup policy. Your questions imply that you are going to be doing the work to recover these very important documents. If you are the one that set this system up in this way, I think you may be out of your depth. RAID controllers are quite often shipped as "RAID 0" and since your system shipped with an onboard RAID controller it may not have been reset by someone who understood RAID. One good thing for you to realize is that your documents were in no way stored on the motherboard, nor did the motherboard itself have anything to do with the setup except for the RAID Controller being built into the motherboard. Your document still exists, except that it is spread in stripes over the two SATA Drives. If you can get your drives to a data recovery house that understands RAID setups, the can probably discern the settings required on another controller in their system, so that they can read your documents. I would suggest that you let someone else handle your file recovery. It also sounds like you just ended up with a high end system and implemented RAID 0 either without thinking or without understanding its consequences. You would have been much better off in terms of data recovery if your RAID setup was JABOD (Just A Bunch of Disks) an acronym that Systems managers can use to pacify a user who thinks he should be using RAID, but doesn't need to. You proobably fall in to that category, as the performance gain of a RAID 0 setup over a plain SATA disk is negligible. If an IT manager set this up, first let HIM fix the problem, then fire him. If you just blundered into it by mistake, you have learned two valuable lessons. The first lesson is work with your system until you understand everything about it, and do not assume that the default settings are correct for your use. It sounds like the default was setup to be used as part of a network with a dedicated backup server. Strange setup, but I've seen it. The second lesson is a lesson that all PC owners should learn: BACKUP,.BACKUP again, and then BACKUP again. I am a total geek, admittedly, and have a wristwatch that has a USB connection to 4GB of flash storage, I will backup a large document whenever I have just spent quite a bit of time working on it. I backup everyday onto flash media every file on my system that has changed since the previous day. Every time I install a program file or upgrade with a newer version, that goes in that days backup. And I have a set of files called Archive (every program installed on my machine with user keys), Archived Mail (every email I have ever sent or received of a critical nature) and Archived extras (everything else I use in the day to day operation of my machine), Those three files, a backup of my Regstry, and my entire My Documents file gets Backed up once a week. About 1GB The storage hog on my machine is Windows. I have just finished slipstreaming SP3 in with my Windows installation disk. (Slipstreaing is a process of integrating your original Windows XP Pro disk with the latest service pack and putting the whole thing on one installation disk.)

Build your new computer, but use the SATA that has the important data that you need as a slave drive and copy/drop it to the new harddrive in your new computer, if that doesnt work, than the HD may have been killed pretty badly...

I think that you have duplicated this question and that i have previously answered it, by saying that i don't think that you can repair a broken raid array by installing it on another computer

If it's a SATA HDD, you can get an external enclosure like one from Thermaltake, and with a USB cord you can plug it into a nother compt

ermmm if i remember right (i may be wrong) when u sue RAID 0 a crash = everyting is gone.... or mby that was RAID 1 i cant remember :S

downoad ccleaner.com it will get any thing u do use or need i use it and it is very great and also go to disk defragment on ur pc and it will save space
