Hey Guys,

Ive been having a couple of issues recently with everything running of my RAID 1 set being a bit sluggish.

Ive just been into Computer Management --> Storage Management and noticed that my RAID 1 set is "Resyncing."

What can i do about this? Ive used various hard disk checkup softwares like HD tune etc, and it says everything is fine with the drives and they are both healthy. So im not sure if its a failed drive or if they have just unsynced at some point somehow?

Im really unsure what to do, and i just really want it fix so i can get on with my work:(

Thanks for any help guys, really appriciated!

I deal with this all of the time when using Windows 7's soft mirror RAID. Everything is absolutely fine, it's just when Windows doesn't shutdown properly, it resynchronizes the data on the mirror drives. It's a safety feature automatically implemented by Windows, and is not meant to cause any trouble. The resync process will complete so long as you leave your computer on, or will completely restart if you turn it off. You can monitor its progress by opening Storage Management (where you were) and refreshing the page. After a few minutes, you will see resync progress determined by a percentage that increments in multiples of 3. The speed of the resync is determined by how much you have stored and the read speed of the drives, etc. The...

The speed of the resync is determined by how much you have stored and the read speed of the drives, etc. The resync process will consume a small but notable amount of processing power, so I usually do not game during resync, but feel free to do anything else. Hope this helps!


ALSO: You can avoid this all together by setting up a hard RAID 1 at the motherboard/BIOS level, but that will involve wiping both drives to set up, and it can make determining drive health a bit more difficult

Thankyou SO much for the quick reply, really really appriciated ^_^
I just refreshed it and it says its at 25% at the moment through the Resync. Im going to let this finish and see if it fixes any of the problems that are occuring!

Ill bare in mind the hard RAID 1 as well if things dont go as planned, if i do feel fresh start is needed then ill consider that:)

Thankyou so much, its giving me some hope!
