Hey Guys,

I recently purchased a Promise FastTrak TX4310 PCIe Raid Controller I have connected to it 4 WD 20EARS 2TB Hard Drives, and they are setup in RAID Mirror giving me 2 Logical Drives.

On 1 of the 2TB i have my Movies, Music & Games collection on the Other 2 TB i have my Daily Backups being saved on it + i have all of my office work files.

The Issue is almost daily I get a failed backup & it says Error: Media Write Protected... when i log in Windows & try to paste / Create a folder its grayed out.

I have tried a Registry Fix i found of the internet which suggested i create a Key "StorageDevicePolicies" & WriteProtect DWord, it hasn't helped.

I have tried running chkdsk on the drive & that removes the media write protect momentarily, but the next backup gets me the same error

I have Full Rights on the drive, I checked & i don't see any settings for it on the Raid Controller... This only happens on one drive, if i backup on the other it works fine.

I have tried the DiskPart, Remove ReadOnly ATTR thing but it doesn't work, need to find a permanent solution.

Any Help is much appreciated!
