I have a WD 640mb, 16mb cache, drive with my OS on it, Vista.
I have a Seagate 640mb, 32 mb cache, drive I use as a data storage unit.
I just bought a WD 1 TB, 32 mb cache, drive.

I built this computer almost 2 years ago and it needs a reload of the OS.
I want to transfer all my data from the Seagate and put it on the WD 1TB.
I want to reformat the Seagate and use it as my OS drive.
Then reformat my WD 640 and use it as an extra drive.

1. Can I load the OS on a different drive with all of them connected?
2. Should I pull the current OS drive and load the OS on the other drive?
3. When I reformat the drive how should I reformat it in Disk Management.
4. Is there a thread I missed with all teh instructions I need?

Any help would be greatly appreciated!

1. Yes, but I prefer to only have the drive I'm going to put the OS on installed and add the other drives in later. This helps ensure that the OS and boot loader are installed on the same drive. This helps negate getting the dreaded "ntldr is missing" when trying to remove a secondary drive.

2. Both drives are 640G so why change it?

3. You don't need to use disk management to reformat a storage drive. You can go to "my computer", right-click the drive and select format. If you use disk mangement, just right-click the drive and select format. If it's the boot/OS drive, you can format it during the install process.

I thought the cache amout would made a difference so I wanted the better cache drive as my OS drive.

I formatted my Seagate then made it the only drive in the box. I loaded the OS on it.
Now I need to put other drives back.

Will the two drives with the OS cause a problem?

I want to reformat that older WD640.

I will use the WD 1TB as storage only.

The cache size on the drive is negligable and you won't notice a difference.

The two os drives won't be a problem. Just make sure the bios is set to boot from the new drive, then you can format the other drive.
