Which application DBXpress or DBXtract is better . . .

1. to recover missing Emails when they do not show up in the Recycle Bin?
OE6 compressed my E-mails. I was not using my computer.
There were no programs running, and no interruptions.
When the compressing was finished my Inbox Emails from January to March
were missing. Sent Emails were still present.
There were no Emails in my recycle bin.

2. to recover data from a hard drive that a computer store - Best Buy
formatted after failing to recover my data?
I had given them clear instructions to call me and to not do anything
to my
hard drive, but they changed shifts and formatted my hard drive.

Can one of these two applications still recover my missing Emails?

Can one of these two applications recover data from my formatted hard drive?

Your knowledgeable advice will really be appreciated.
Thank You,
