how can I tell if I have this drive? is there a way to do it by manufacturer date of the xbox 360 or...

?
In my experience (in the UK at least) Lot No. 1131X and under are not 1175, 1132X seems to be a mixure of Corona/1175, Corona/1071 and Trinity/1071. In other words 1131X appears to support drive flashing and RGH whereas 1132X is a bit of a lucky dip.
Again, this is just my experience.. best to check the maunfacturing date agaist the database www.360drives.com
