overclocking attemps damage secondary hdd?

I have read that attempting to overclock can wipe out your hdd so you have to reinstall windows. I have my os on a sata raid controller and my secondary hdd on a pata raid controller (both onboard). Then I have two optical drives, one taking up each of the two ide connections.

Last time I tried to overclock I backed up files onto my sec drive and disconnected it. Then windows said that there was a "significant" change in my hardware :disgust: and I had to call ms for a new cd key. To make matters worse, the overclocking never worked for me.

Well I want to try again but do I have to disconnect my sec drive even though it does not have the os? I really don't want to have to explain to the guys overseas why I need my third cd key.
 
Back in the days before PCI/AGP bus speed locks, when you overclocked the FSB, you also overclocked everything else, including the PCI/AGP busses. This would cause the PCI/AGP busses to run out of their 33/66mhz specifications. This could really cause trouble with the cards and the hard drives.

I think such trouble is just about gone with todays mobos. That doesn't guarantee that you won't have problems, but I think they are far less likely if your mobo locks the PCI/AGP frequencies in spec when you overclock.
 
i think its possible to corrupt registry entries or startup files on bad boots. bad boots being a result of cpu or ram instability.
 
LTC8K6 is right. If you can't lock the pci/agp bus speeds, then when you push the fsb to strange values like say 180mhz or 210mhz your ide controller might not like it and will corrupt the data going in/out of your hard drive. Doesn't take long before the drive won't boot anymore and you have to re-install.

I think though that there are still plenty of new boards that don't have bus locking. I know my nForce2 board doesn't, but it's not "new".
 
Any memory corruption can lead you to wipe out a filesystem.

Overclocking can lead to memory corruption.

In detail, memory corruption leads you to filesystem damage, even fatal filesystem damage, via the filesystem buffer cache. The buffer cache stores blocks that belong to disk, and where they belong. If random changes in memory orrcur, then the information where a certain block belongs can be overwritten. And hence the block gets written to the wrong place. If you are unlucky, a block belonging into a plain file is suddenly written over a directory or over an allocation table, wiping out huge numbers of files in one strike. Or it can even end up cluttering critical metadata in the filesystem without which the OS can't mount it anymore at all.
 
good replies guys. Unfortunately my asus k8v doesn't have a pci/agp lock. It does have a divider but if you don't hit that magic number pretty closely, either the divider won't kick in or you will still be running the pci/agp bus faster (but not by much).
