Go to SolutionPowerEdge 2950 HDD Predictive Failure
Hi Experts
We have PowerEdge 2950 with RAID 5 PERC 6/i Integrated. It has 3 SAS HDDs and it is showing HDD Predictive Failure for two SAS HDDs and each HDD is 400GB. The same size disk is not available now and vendor is asking us to use 450GB HDD. Is it possible or we should insist on getting 400GB SAS HDD?

You can always use larger drives and partition the space you need. This is best practice with drives of the same size as well because different manufacturers will have slightly different sizes for the "same size" drive.

It will work, but there are some risks involved. Here is a good post on spiceworks where a couple people talk about possible issues.
