Hi there


I'm having some disk problems with my mid 2009 MBP. Basically, it froze while I was using it so shut it down by holding down the power button then it wouldn't boot back up to Lion, just got stuck on the grey loading icon so I ran Lion Recovery, and disk utility to try and repair the disk which basically said it was corrupted so I needed to backup my files and format it. Luckily I had a time machine backup from a couple of hours before so that wasn't a problem. When I tried to format the drive however, I just got error messages (Wiping volume data to prevent future accidental probing failed) so I thought the drive was dead, and basically used it as an excuse to upgrade to an SSD. When the SSD arrived, I put it in and ran Lion Recovery off a USB which wouldn't format the new drive - gave me this error message 'File system formatter failed', and the drive doesn't show up if I try and do a fresh installation of Lion. I thought there might be a problem with my Lion Recovery USB so I tried to format both drives, old and new using the Snow Leopard disk which gave me this error - '

POSIX reports. The operation couldn’t be completed. Cannot allocate memory' on both drives. I tried both drives in a windows PC, which had no problems formatting/writing/reading either disk. Any ideas what the problem might be, or a way around? I tried using MacDrive to format either drive on the windows PC, but I still can't do anything with it in recovery. Is it worth going to an apple store, or is this way above their heads?
