My internal Hard Drive won't initialize

[SolidWarSnake]

I have 4 hard drives 2 1TBs and 2 4TBs. They were originally in RAID 0 but i couldn't get the computer to start. It would load into the UEFI Boot menu. I put the drives back into its normal setting as separate drives and getting 3 of them to work but the 4th drive according to disk management is unknown and not initialized. It is also saying that it is 8TBs. When i go to initialize the drive using GPT it says: Data error (cyclic redundancy check). I go check in device manager and I see the problem, the drive is listed as Intel RAID 0 Volume. The drive is a toshiba. I tried plugging it into another computer but this time it says: the request could not be performed because of an I/O device error. There is not data on the drive but i would like to use it again, I at least want to know if i should just trash it and get a new one, thanks in advance.

If your talking about the two drives you used in a raid 0 or a raid 1 array.

You should of broke the array by using the raid extended bios options of your motherboard.
If you do not do this, and intend to use the drives that were part of the array.

It is why you cannot initialize the drive in windows.

You have to delete the raid array and setup as said via the raid extended setup menu options of the bios first.
returning each to single drive format and layout. it why you get the I/O error when trying to initialize the drive.

Format each drive gain.
And initialize it via windows disk manager, and you should not get the I/O error message.

Wow feel like an idiot for not realizing this, you reminded me back when my computer would only load into bios, i deleted one raid volume forgetting to delete the other since im new to doing it. since i turned raid off the menu which for me was intel rapid storage devices was missing i couldn't figure out how to delete the array.
To clarify for anyone else who might have this issue
Restart your computer
Go to your bios menu for me it was UEFI for my asus z170 deluxe
Turn RAID mode back on, turning RAID on will not mess up your drives since you need to create them after RAID is on
for me it enabled a menu for intel rapid storage devices
simple click the Raid volume and a delete option will be available
turn RAID off then exit the menu
thanks Shaun o for the reminder
but i wonder why one drive was usable but the other was still in RAID
