Rebuilding raid 1

Hello all,

After a catastrophic hard drive failure last year, I started from scratch with 2x Seagate 1.5TB 7200rpm SATA drives on a mirrored Raid 1. One of the drives just went bad as of a couple days ago, and Seagate already has a replacement drive on the way.

Unfortunately, I just noticed on the return shipping instructions that I should've contacted them if I was running a mirrored setup. I just called them, and they informed me that is because most Raid arrays usually require the exact same model number of drive to successfully rebuild the array. The Seagate rep stated that although the same model was allocated for my advance replacement order shipping today, there were none in stock and it could be substituted with a 2TB model.

I've never had to deal with rebuilding a raid array before. If I do get upgraded to the 2TB model, am I going to have problems?

Edit: onboard Intel ICH10R Raid controller

depends on the controller. some can rebuild and use only part of the disk, some cheap controllers might need an exact replacement or matched disks. were you using a RAID card or on-board/motherboard RAID.
 
FakeRAID may require the same exact drive, but I'm not totally sure.

I know that software RAID can use any HDD model, and hardware RAID requires the exact make/model.

I'd like to know how this turns out as well.
 
I vote it will work but it won't hurt anything if it doesn't.

Don't forget to update!

You shoulda made a Poll with this one. :)
 
1. If you need assurance, always backup the data first before trying.

2. I tested the following a few weeks back. FakeRAID-Windows XP-ICH6R - 2 x 80 GB . 1 x WD, 1 x Seagate. Shutdown. Replace WD with Hitachi 160GB. Boot into FakeRAID option ROM BIOS Screen. Add the Hitachi back into the array as member disk. Seems OK.

3. However, take note that for my case I use the original RAID software version as listed on the support website. I did not upgrade to the latest FakeRAID software version. As seen recently sometimes upgrading to the latest and greatest version triggers odd dependency issue and may caused problem for very old hardware and bleeding edge RAID drivers. To be safe, I recommend backup your data 1st.
