    Remove disk partition

    A friend has a Compaq Presario CQ62 laptop running Windows 7, which has a 15 GB D: drive ("Recovery") and a 100 MB F: drive ("HP_Tools") as well as the main C: drive, and I gather these are part of the OS installation and should be left there.

    There is also a 200 MB H: drive ("System") containing a single "$AVG" folder with a single "$CHJW" subfolder with four 1 KB files (avgcchff.dat, avgcchfi.dat, avgcchmf.dat, avgcchmi.dat), which looks like a leftover from an uninstalled AVG antivirus program. Can this partition be safely removed, and if so, what is the procedure?

    Option 1
    Do nothing, it's only 200MB

    Option 2
    Assuming the partition is the last partition - can you post a screen shot of Disk Manager - then you can delete it after you have taken a full image backup.
    Use Minitool Partition Wizard free to delete the partition and expand the C:.

    Thanks for your replies.

    Here is a screen image from Disk Management.

    I have not used the Minitool Partition Wizard before, but it looks straightforward. If I delete the H: partition, will that automatically return the space to the C: drive?

    Are you absolutely positive that there is nothing you NEED on that partition? Not just a guess - an absolute certainty.

    A deleted partition becomes an un-allocated space on the hard-drive. Such has to be merged with an existing partition adjacent to said un-allocated space.

    Your screenshot shows that partition designated as active. If you remove it, I would expect the computer to no longer boot.

    Thanks for your further replies. After checking further, I confirmed that there are some hidden files on the H: drive, and presumably the system boots from there, so I will leave it there. Why might someone set up a PC with configuration like this?

    That is standard for W7 and above, but the partition is not normally given a drive letter and effectively remains hidden. You could just remove the letter.

    cheers, Paul

    Thanks for your reply. How is the drive letter removed?
