How do I recover files from an USB flash drive?

My friend got a HP 16GB USB pen drive. The problem is, he defragmented it. Now when we are connecting that device, its asking us to format it.

As it has very important information and can't be lost, is there any way to get that back? and how?

Pen Drive details: size 16GB, Filesystem: FAT32 (Not sure) but its now showing RAW.

Can anyone help on this. We use Windows OS (XP/ 7).

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I wouldn't think its a duplicate. Here, the disk is defragmented and I still don't technically understand what makes a defragmented disk need to get formatted – Surya Jan 25 '12 at 15:24
Defragmenting it should not, in itself, result in loss of data. Note that if you have data that's very important, you should never keep it in only one place. – pjc50 Jan 25 '12 at 15:27
Obvious question for recovery though - have you tried it in more than one computer? – pjc50 Jan 25 '12 at 15:28
Are you sure the drive isn't an el-cheapo-masquerading-as-high-capacity drive? – Sathya Jan 25 '12 at 15:40
It doesn't help now and I'm sure the thought has now occurred to your friend but "very important information and can't be lost" really should mean copies are kept in at least three separate devices in at least two separate buildings. Backups! – RedGrittyBrick Jan 25 '12 at 15:55

I would suggest running TestDisk and analyze partition table. Then you can try to restore it (it may corrupt your data).
