I have Window 7 Professional Service pack installed in my Laptop Lenovo Thinkpad t420.

After formatting the disk, and install Window 7 (detailed as above), I went to Computer --> Manager --> Storage --> Disk Management to split my 300gb C partition into 2 partition:

• C (which is 162gb)
• E (which is 140gb)

Is work fine for about 2 days. Today, when I turn on my computer, I'm very suprise that the E partition is disappear. I can surely confirm that I didn't do any stupid thing yesterday. And before I shut down my computer, everything was fine.

In general, here is what I did during the last today (from the point that I formatted the disk, and installed Window)

• Format 300gb hard disk
• Install window 7
• Install eclipse, db2, .... ( I'm a developer)
• Install some other tools (Open office, Skype...)
• Install PGP (http://www.symantec.com/encryption) <--- I'm forced to used that due to my company policy
• Use Computer --> Manager --> Storage --> Disk Management to split my 300gb C partition into 2 partition as described above.

It worked quite well for two last days. Until day...

Can you please help me to recover my lost partition ?

Thank you!
