You don't need to align the drive when using Windows 7 as long as you created the partitions using Windows 7. If you created the partitions using XP and then attached the drive to a Windows 7 system, you'll get very poor performance because the partitions won't be aligned.
It's not what OS you use the drive with that's the issue, it's what OS you partitioned the drive with.
I don't think paragon is new enough to understand the advanced format. I'd say this is the problem. I'd back up all the data on the drive and reformat it using Win 7. Just as a precaution, I think I'd delete the partition and recreate it before formatting.
I got 6 partitions - so if I moved two partitions data to another hdd and delete and reformat these two only using Win 7 then restore data back to the two partition and so on to the rest of the 6 - is it going to work ? or I must delete the complete hdd ?
(this because I dont have enough space to move every thing)
when I format , what is the cluster size I should select ? or win 7 does not give me that option ?
@Hawkeye22 did not know it is important
so I must delete all partitions not just two by two!
isn't what we say enough for you? what do you want btw?
Just look at your top post and start coming down. You can see how much info you needed to give in advance and how much we have already told you. Still you are asking questions. if you cant get a separate hd, then stay happy with what you are getting. if you keep asking again and again to what to do, in time no one would reply.
