My new Dell laptop was installed with Windows 7 & PGP WDE in it. This was performed by my office team (by the infrastructure Team).

I did a shrink on the C: drive, and created new volumes (D, F, & G).

E: was already allocated to the DVD RW Drive.

Both diskmanagement and PGP Desktop was initially showing all the drives. After seeing everything OK, I distributed my entire data (both Official & Personal) across to all the volumes, including C, D, F, & G

The setup ran for 3 days without any problem

After some automatic windows updates I was asked to restart my laptop.

** Problem started here.

Now all the hard disk drives except C: is missing. (ie, D, F, & G).

When I go to disk management it shows only one volume C:

C:   Simple   Basic    NTFS      Healthy (System, Boot, Page File, Active Crash Dump, Primary Parition)   465.75 (Capacity)   465.75 (Free Space)     100% (% Free)     No  (Fault Tolerance)      0% (OverHead)

PGP Desktop also shows only C: as only parition available. Remaining paritions available earlier are gone now.

Windows explorer shows only C: as 171 GB Free of 233 GB. The entire space allocated for the other volumes are unusable now.

The data stored in (D, F, & G) was so important to me, so I did some googling & recoverened the entire files using TeskDisk utlity

I am happy that I got all the data stored in the missing volumes, but still unable to mount the remaining drives.

I am still doubtfull whether something else will happen and my remaining drives also will go disappear.

Any idea ???
