How can I see the hide partition in HDD

Hide Your HDD Partitions Hide your HDD partitions 1. Go to Start > run > type “diskpart”.
a dos window will appear with following like that
DISKPART> 2. Then type “list volume” without quote
It will look like this.
Volume### Ltr Label Fs Type Size Status Info
————– —- —— — —– —- ——- —–
Volume 0 F CD-ROM
Volume 1 C NTFS Partition 7000MB Healthy
Volume 2 D soft NTFS Partition 8000MB Healthy
Volume 3 E —- NTFS Partition 8000MB Healthy
3. If u want to hide drive E then type “select volume 3′ without quote
then a message will appear in same winwods { Volume 3 is the selected volume}
4.now type ” remove letter E” without quote
now a message will come { Diskpart Removed the Drive letter }
sometime it requires the reboot the computer .
Diskpart will remove the letter .Windows XP is not having capabilty to identify the unkown volume.
Don’t afraid ur Data will ramin same .
to Come back the Drive repeat the process . but in 4th step which is shown in this post replace ” remove” to “assign”
means type ” assign letter E” without quote
The above method won’t work for the drive containing Operating System and it can also be done using System Manager>Storage Manager

people are always complaining why viruses is back even after full format?!!

will that is what I'm going to clarify in the following lines:
usually it is a good idea to backup your data to a USB stick or DVD before
fully formatting your HDD with its all partitions, but the thing you may not aware of is that you may copied the viruses with your files , so don't even think about restoring you files unless your fresh system is ready , i mean
you must have all necessary updates and fixes installed in addition to antivirus with latest virus database definitions and make sure that no software installed from a home made or Unreliable cd .
then you can do restoration.

BUT what if my data is too large to be backed up.??

will i have a good trick for that .assuming that you have 2 partitions, you can put all your important data in a partition other than C drive (boot partition). then make sure that you Hide (not format) that partition using third party tools like (partition magic) or (Acronis) that you may find for free in a maintenance boot cd like Hiren's BootCD
by hiding that partition you guarantee that the newly installed OS on the newly formatted Primary Partition(C) cant see old staff that may be infected with a virus or more, this way you can protect the fresh copy of windows from being infected as soon as it boots up for the first time.
now as i said before you must have all necessary updates and fixes installed in addition to antivirus with latest virus database definitions .
Now time has come to un-hide that old partition to make it visible and assessable , by using the same steps you did to hide it.
when you restart the pc the new OS will detect that Partition and the antivirus will start cleaning viruses if any.

all the best
