Okay, i've just realized by looking at the blocks/ folder, that the client is indeed re-downloading everything again (no wonder its taking forever) and here's the weird part: It's re-writting and replacing my backup (the entire blockchain I copied). I realized this because from block blk00000.dat to blk00140.dat the date is today, and from 141 to the latest file, the date is from 2 days ago (the last time I used the wallet in my other computer). Why is it doing this? It's like the client didn't recognize the blk files and started from scratch or something.. weird. The backup folder is from the latest version, same wallet etc.. (again its the entire folder). I don't get this.
It is actually not redownloading, it is rebuilding the entire database, which needs to open and read the blk files. This is why the timestamp is changing. If it were re-downloading, it would take much much longer.
I am on the blocks folder with the latest file that has today's date and the size of the file is increasing when I press F5, therefore it is not only opening it but re-downloading it. It's taking forever. This can't be verification only.
