OT: This is probably already known but, if you have a big plugin and it takes a long time to save and the end result will be a master, http://www.creationkit.com/Version_control can speed things way up since you start with a blank plugin after every merge. I would save my 2.5MB plugin and it would like like 8-10 sec and I would have to minimize then maximize the CK or most of the GUI would just be white. After merging, I have a tiny 100KB plugin that takes 1-2 sec to save. When it gets larger and saves take long again, merge it and repeat. It's a lot less crashy when it only has to save a little at a time.

Shouldn't take that long... Mine is sitting at 11,230 kb and it takes me 18 seconds to save. Do you have anything unusual in your file? I can't even think of any examples... Anything abnormal or odd that you're trying to do with your mod that the CK perhaps might not like? It seriously shouldn't take long to save.

dunno sometimes is crashing when I load a region in my island , other times doesn't crash in the sae region so I really don't know , even if I did add custom models , those are all working fine in game and in ck ...

Your hard drive could be not long for the world :/

I bought a couple of new ssdI will have to mount on the new system , two ssd one of 128 for SO and one of 512 for programs ( and steam )

Yeah it could either be a number of random little errors that could be impossible to track down, or your HDD could indeed be possibly failing. The CK shouldn't crash often at all unless you're doing a bunch of crazy stuff that you aren't supposed to be doing.

well now when I load my land and I try to save it keeps untaking the save command , and I don't get why ... so far I coudl save finely whatever the time it took ...now doesn't ...

Ha, I'm talking about how my CK never crashes and it just completely banked when I clicked 'OK' on a topic info. xD

Weird. Maybe you need to reinstall the CK or something? It sounds like something, either your esp or your HDD maybe, is going downhill...

I would be seriously worried about that hdd. They seldom give very much warning though. If you have had any circumstances where windows has told you to check that disk on boot, I would replace it ASAP.
