Title:

External Hard Disk(s) not mounting in OS X 10.7.1

Text:

My Mac was running OS X Snow Leopard when I got it. My External HD(s) were working fine, with Win7 and OS X both, no problem at all. Now, when Lion came out, I obviously went ahead and installed it. But, my external HD(s) don't seem to work. They won't even mount itself. However, my 16 gigs flash drive works fine with Lion and not my HD's (WTH). I have tried repairing it, verifying it from disk utility and all...still not working. I re-installed Lion, still no luck. But it still works on 10.6.8. They are in the same format and raid type too. The only difference between these two is the space. Thats it. So, What MIGHT be the problem here.? What's up with 'my flash drive working and not my HD's ?' How do I get my HD work on Lion (10.7.1)? Any advice/suggestion/solution will really be appreciated.

P.S I don't know the technicalities of tweaking your OS X (in case someone suggests on solving this issue with the OS )
