Nakon dodavanja novog diska sve otislo u #$%/

nastavak price ne engleskom... (pokusao sam i na drugim forumima, ali.... )

i menage to restore data with "easus data recovery" and now roughly i can see what actually happened; or EasyBCD or my attempts to repair situation with windows repair (boot dvd) f%$&/ up situation with HDDs.
Not just that, in panic to return everything as it was, it seams i made one disk dynamic so it "took" exactly 1TB from 3 HDD.
so situation right now is
1 HDD all fine with 300 GB (system disk)
2 HDD 2 TB (this was the disk i made dynamic) 2TB is shown in BIOS and now i have problem with this this cuz after i striped volume from it it is "offline" BIOS see it, and easus data recovery, but in disk management i can not do anything with it (it is just shown as an computer but i can not doo anything with it. when i try to make it "basic disk" it gives me error that disk has to be online. in disk management it is shown as online.

other disks
3 and 4 r relatively ok. when i restore data i get all 1,5 and 2TB of data (their real size), but in disk managementand in windows and in any other program even BIOSi have them in size of 0.5 and 1TB. and this cutted size all works "fine" can do format, can put files there....

So question is:
1 how to restore everything as it was before.
2st HDD, to make it alive.
3rd and 4rd HDD to restore "real size?

btw would low level format do the job?
