It says there is a hard drive that is defunct however the system does boot up but the application does not work and I think it is due to the oracle not being able to run. How to recover from the data corruption due to the drive failure?
A RAID 5 array would still allow you to access and use the data with one drive having failed. So, since your application isn't functioning I'm assuming that you've lost more than one hard drive in a RAID 5 array OR you've lost both drives in a two drive RAID 1 array OR you've lost one (or more) hard drive(s) in a RAID 0 array OR you've lost a lethal combination of drives in a RAID 10 array. Any way you slice it you will have to replace the failed drives and restore the data from a backup. The only other "safe" option is "roll the dice" with a data recovery service (no guarantees of success) and (will be much more costly than it would have been to have an active backup system in place). You can always try to recover the data yourself; there are various techniques, none of which are safe and WILL make data recovery service less likely a successful option. Good luck!

you need to find the floppy driver for your chipset and install it to detect the hard drive. newer chipsets use a hard drive mode called AHCI, or like you mentioned RAID.
alternatively you need to go to the BIOS and disable these or change the setting to IDE/Legacy to detect the hard drive. the only advantage to the AHCI or RAID is hot-swapping the hard drive and Native Command Queuing (supported by newer hard drives) but the performance gain in XP would be negligible.
Why don't you try to get your main drive running before getting into Raid Configurations. Set your single drive to Master and run setup telling it you have one drive. Once you are satisfied that it is not some other fluky error, put in the other drive and I believe if SATA you don't even have to worry about Master Slave. Go about your boot and go into setup again. Hopefully all is good with the world and all that has to be done is fix up BIOS. No matter what, there is never an " out of the box " clean system. Make sure you plug your cables in correctly. I assume you're running EIDE. You'll get it.
The G-Raid drives use RAID-0 which splits data across both internal drives, so unfortunately the remaining drive will not be able to be used to recover any files as it will only have fragments of each file on it - the other fragments having been lost on the faulty drive. Also, you will need to contact G-Tehcnology to get a replacement drive - the drives used (from memory I think they are Hitachi) have special firmware on them and other drives will not be compatible and you'll start getting strange errors. G-RAID drives are designed for high-throughput work like video editing, not for redundancy - they should be treated as a single drive where if the data is important you have a copy of it on another drive. Keeping data on only one drive is not a back-up, it's a problem waiting to happen. Sorry I couldn't give you any good news.
You don't say whether or not your os is on the RAID 5 partition. Assuming that it is (for performance reasons, this is not recommended) then you should check to see if you have the option of configuring a separate raid configuration on your raid card (e.g. do you have a card with more then one RAID channel?) If this is so, I would create a separate RAID 1 array and install the OS just on that. Then you can mount the RAID 5 array with your data intact. Once you're up and running, you can remove the old OS partition, as it's no longer needed.
hi, you need not have to upgrade the BIOS,, set the SATA HD on the IDE channel in the BIOS, or what options r avilable for SATA controller, if it is set to RAID, you will need a raid utility to format the SATA, or it wont shoe in windows, let ,e know
