RAID data backup
I know that RAID 0 setting will strip the data to store them onto 2 drives. When using an external HD to backup data (such as Maxtor OneTouch), will the data be saved as regular form (non-stripped)? or Is there any problem transfering data between RAID and regular HD?
Thanks in advance.

- Restoring data or adding another drive to configure Raid 0 array with intel application accelerater is easy. After installing my second hard drive I started my computer, logged into windows ran the intell apllication accellarator program and then I surfed the web while it restriped the data and then restarted when it finished. I didn't have any problems and I got to keep all my programs/files/data.Make sure you have the right chipset!!
- A bare-metal restore (without installing Windows first) with RAID0 is tougher than on a single drive.
The other issue is that when a RAID0 array crashes, data recovery is far more difficult - in many cases, impossible - while it is usually possible with a single drive. - YES you are correct "A bare-metal restore (without installing Windows first) with RAID0 is tougher than on a single drive. " you have to press f2 and change the bios Raid controller to "Raid on" and then press CTRL i to enter intel raid option rom utility to create a raid volume. You'll need your Raid controller driver as apposed to your SATA controller driver when your installing windows too. Thats the only difference I've done both."The other issue is that when a RAID0 array "crashes"(whats your definition of CRASHES)data recovery is far more difficult - in many cases, impossible - while it is usually possible with a single drive." Neither a single drive nor two drives configured in RAID 0 offer data redundancy so if a drive "breaks"("CRASHES"stops working) you will lose all of your information. If your just plain ignorant or unaware of security problems that windows/IE offers and they mess up your system having a single drive or Raid 0 configuration will not effect your repair.
The data copied from RAID0 on the external drive are regular files or RAID specific files? If the external drive is connected to a single-drive system (non-RAID), can those files be used normally without some strip-reversing process by the backup program?

- You have been misguided!!When files/data are/is copied to a normal drive they are no longer "RAID specific files." whatever that is/means!!If data is copied from RAID0 to an external drive they are no longer "RAID files?""If the external drive is connected to a single-drive system (non-RAID), can those files be used normally without some strip-reversing process by the backup program? "WHAT???"If file are transfered from a RAID volume to an external drive there no longer "striped" on the external drive so YOUR QUESTION how can those files be used normally without some strip-reversing process by the backup program when there not striped in the first place!!!!!!!! MAKES NO SENSE BECAUSE YOU CAN'T UNSTRIPE a single drive can't be stripedYOU HAVE TO HAVE AT LEAST TWO DRIVES CONFIGURED TO RAID 0 TO HAVE A STRIPED VOLUME!!!!! duh!WHEN YOU COPY DATA TO A SINGLE DRIVE ITS NO LONGER STRIPED!!!Make sure you have the right chipset!! before installing IAA

Restoring a RAID0 array is more complicated - make sure whatever backup software you buy can do that.
