Howzit guys,

So I bought myself another 160Gb to add to my current one 160gb Hdd. :)

Both drives are SATa. So I installed it in my shuttle xpc system and off I went. All good. Then apon rebooting the system I decided to have a raid setup..

So I press F4 to enter RAID tools and make a RAID-0 Stripped - 32Kb.
Reboot only to find ALL infomation from both drives gone! :eek:

I didn't realise it would cause that I got no warnings, nothing! Luckily I had 50% of data on back up and get the other 50% data from a friend.

What I want to know is, why are my drives loosing 2Gb when in SATA RAID mood. One drive is 153Gb and the o other is 149Gb so that is just a tad over 300Gb..but on my system is 298Gb. Any ideas why this is?
 
I'm guessing that the drives are different, hence the 153 vs 149. Since the RAID setup splits the data across the two drives it can only use the capacity of the smallest drive hence you're seeing 2*149 rather than 153+149.
 
im agreeing with rpstewart that the drives are different and raid works by using the smaller drive size.

im suprised that you didnt realise that you would loose all existing data on the drives tho

Is there no way to have the extra space back while having the raid setup?

Not with the most RAID controllers, they operate at a disk level so either a disk is in the array or it isn't and any capacity not used is wasted. This is why the recommendation is always to match disks in a RAID array.

The newer Intel Matrix RAID controllers don't have this problem because they can put parts of multiple arrays on each disk so that you can have 2 HDDs with, say, 100Gb of RAID0 on each and 150Gb of RAID1 giving a 200Gb c: and 150Gb d: from a pair of 250Gb disks.
 
get on with it :) live and learn ^^^^

Shame you lost all your pron though haha :D
