HDD Failing

  Boghound 13:30 20 Jul 2009

One of my HDD's is failing. I have two (300gb)in a raid formation. I have ordered a 1TO and wonder if I replace the old with the new would it work or id it best to do a complete reinstall of XP on new disc. If so, would I have to install XP or could I boot from an Acronis back up disc? Or do I install XP then Acronis and reinstall from there?

What sort of RAID configuration do you have (i.e. what RAID level)?

Don't understand the question

Depending upon the RAID level used, the impact of changing a drive may be trivial or severe.

Thanks.......Of course it's "Raid 0"!!!!

If you genuinely have RAID 0, then, your data is spread ("striped") across the two HDDs. There is no redundancy (which is what RAID really set-out to achieve originally, so as to provide protection against data loss in the case of a drive failure)

Theorectically, you could replace the failing 300GB drive with a 1TB drive, but in a RAID 0 configuration the smallest drive determines the amount of spacte used on each of the drives.

You also have the issue of copying the data from the failing drive to the new drive. Cloning the drive with something like Acronis True Image should do this (although in a RAID configuratuon I'm not absolutely sure if TI would do an adequate job).

In any event RAID 0 is intended to improve performance, but for virtually all non-server based installs that is highly questionable (and could make things worse).

Personally, I think you'd be better off cloning your whole 2 x 300GB RAID 0 setup on to the new 1TB HDD and using it as a single HDD (i.e. without RAID). If you've then got a spare slot in your unit, you could use the good 300GB HDD for on the fly back-ups, pagefile etc.

Thanks........I'm going to clone the discs with Acronis and hopefully I will just have to install new disc and everything will be ok....
