At work Im also in charge of some of the IT stuff. Our server is setup in a RAID 5 setup. We have Western Digital WD3200AAKS hard drives. The main drive is in a degraded state. Its deleting installed programs and files and the RAID software is going off. Problem is that drive has been discontinued.

The new model is WD3200AAKX. Only difference between the 2 drives is that the AAKX model has a 6.0Gbps throughput versus the 3.0Gbps of the AAKS model. I planned on ordering 2 and letting the first rebuild, then swapping in the 2nd drive. Will this work or do I need the exact model? Id prefer not to use the AAKS since its been discontinued for quite some time and its going to get harder and harder to find.

In theory if it is at least the same size it should work. A couple of caveats.

1. All 320Gb drives are not the same exact size, so it needs to be the same or larger.
2. Since it is a Western Digital it needs to be a drive designed for RAID.

http://www.tomshardware.com/forum/251076-32-raid-issues-western-digital-hard-disk
RAID issues on Western Digital Hard disk
WD's "RE" (RAID Edition) HDDs support Time-Limited Error Recovery ("TLER" ):

As a non-TLER HDD fills up with data, the error detection firmware
might take too long, and the RAID controller may drop that HDD
from a RAID array.


For example a RE4 drive such as on this page: http://www.wdc.com/en/products/products.aspx?id=30

RAID-specific, time-limited error recovery (TLER).
Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.


The controller can also play a part in is this so...........

Hope this helps
Roger

I am probably just going to swap to a pair of Seagate Barracudas that are 500Gb a piece. Will that be fine to do?

That is hard to say, It sounds like you want to keep using Home grade drives instead of Enterprise drives in a business server?

You'll have to research the specific model of Seagate drive you are looking at.

It is basically a mom and pop shop. Its equivalent to an average house now days. 5 computers with access, Server 2003 that distributes customer Excel proposals. No high data transfers or anything of that nature.

I hope you also have backups. I would want to have a good Backup first then change the drive, just in case.

Unless someone else has a better idea, I guess you will have to try the Seagate drives. Your success is probably tied to the controller.
Is it a desktop computer with built-in RAID? IF so probably no problem.

If however you are running a heavy duty built as a server then maybe not so successful.

Roger

P.S. If the server is attached to the Internet then read these messages.
New ransomware called Anti-Child Porn Spam Protection

A new variant of the Malware Protection ransomware has been released called Anti-Child Porn Spam Protection. This ransomware pretends to be from a legitimate government organization that states that the infected computer is sending out SPAM that contains links to child pornography sites. The ransom program then states that in order protect yourself, and others, it has encrypted your data using Advanced Encryption Standards, or AES, encryption. Just like the Malware Protection and the ACCDFISA Protection Program variants, these files are not actually encrypted but are password protected RAR files. The hackers then require you to send them a Moneypak, PaySafeCard, or Ukash card for values ranging from $500 - 1,000 USD in order to get the password for your files.


At this point in time there is no recovering the files.

Its an actual server. Not sure on exact specs as it was built before I was here. Its not a desktop I can tell you that. There are no good backups. Im going to do a fresh install of Server 2003 R2 SP2 and import configuration backup files.

If it is older you will probably be fine.
Good Luck
