My TeraStation has had a RAID error for ages and has been working fine but in light of my main PCs hard drive corrupting I thought I should fix it.

According to http://www.buffalotech.com/knowledgebase/users/kb.php?id=10135&category_id=0&sid2=, to fix it I need to restructure the RAID array.

Now my question is this, on that page it says
"This means that the data on the replacement drive will be erased, NOT the data on user array."
But since I haven't actually replaced a drive, this error has just developed, does that mean my data will be erased?
 
Its 4 disks running in Raid5, all 250gb (unformatted) each. The entire array is currently full at 695GB. So yes there should be some redundancy but I dont know enough about RAID configs to know if there is enough redundancy with raid5 to be able to restore everything if that drive gets formatted.
