Cannot resize partition below 60 GB

  1. Hi, I bought an Asus laptop with Vista preinstalled. I want to shrink my
    Vista partition, but Disk Management tool refuses to shrink below 60 GB. The
    partition (where Vista is installed) is now 60GB, with 45GB free space, but I
    cannot shrink it further. I tried disabling page file, reducing shadow copy
    storage area, disabling hibernate, but with no luck. The page file is about
    2GB, the shadow copy storage does require about 15% of disk, so at max it
    would be 15 + 2 + 0.15*60=26GB, add 4GB for data and we have 30GB max. Why
    Vista needs another 30GB of my hard drive? If this is a bug, where should I
    file it?

  2. A follow-up. I disabled restore points, and Vista let me shrunk the partition
    by further 13GB. But Vista did not succed with the shrinking. It showed me an
    error window, telling to look up the error in events journal and advising me
    to restart Vista. I looked up in the event journal, and found that the error
    was made by atapi. In that error entry I did not find anything more
    informative. So I ran the complete disk check, which took about 15-20
    minutes. This disk check did not find any errors, but after the resize
    operation failed with exact same error. So does this mean that my harddrive
    is poo, or I just have to try and recover Vista from my recovery partition
    (probably the recovery will be just reinstall)?

    Have you tied resizing using diskpart from an elevated command prompt,
    instead of from Disk Manager?

  4. Yes, but it failed. Just did it again to make sure. But the error message is
    different. It says that access was refused to do perform operation. Note that
    I ran the command line as administrator, and did that from administrator

    Ok, I thought it was worth a shot. Sorry that didn't work out.
