Hi, This is kind of long, but I wanted to include all the necessary detail. My brand new Dell Dimension E520 came with Vista Home Premium pre-installed on the 250GB hard drive. The drive was set up as a single partition. This does not suit my needs, so I attempted to use the built-in Vista Disk Manager utility to set up new partitions. It didn't work. To be clear, the drive actually arrived with three partitions on it; the C: NTFS partition where the OS was installed, a D: NTFS partition labelled Recovery, and an inaccessible, unlabelled EISA partition. I have not attempted to make any changes to or remove the D: and EISA partitions. The C: partition encompasses 224GB of the 250GB (theoretical capacity) drive, so that is where the changes need to occur. I first shrank the C: partition, using the Disk Management utility, but it would only shrink by about 110 GB, despite having only 36.8 GB in use. That's including the Page File. This left me with a C: drive of about 120GB, most of which was empty. Repeating the process would not shrink the partition more than another 1GB, or so. So, I tried moving moving the Page File to the new partition created on the freed up space, defragging C:, rebooting and trying again. No change. Hours of research on MS KB, Technet, Google, and several calls to Dell later, there's still no change. Despite the mixed reviews, I downloaded Acronis Disk Director (ADD, nice acronym), created the bootable Rescue Disc, and tried that. It can't even see the physical drive, let alone the partitions on it. It sees my external USB drive, but not the internal SATA drive. So, figuring I have nothing to lose, I installed ADD in Vista and ran it there. Same thing. It doesn't even see the drive. I have not been able to find any other reports of this particular problem. I don't really see this as an Acronis problem, though. There's clearly something wrong with the image Dell is using to set these machines up. Whether it's their fault or Microsoft's would be hard to prove, but sizing an existing partition is not one of the known issues with Vista, so I believe it's Dell's fault. But it's a situation Acronis should be aware of. So, since Dell refuses to take any responsibility for this, or offer any assistance, I'm currently planning on returning the machine. If I have to struggle this much to overcome this one problem that shouldn't exist, how many others are lurking in the background? I see no reason why I should I be stuck with a defective OS on a brand new machine. So, at this point, I don't expect much, but I'll take any suggestions, advice, or commentary anyone cares to offer, and hope this serves as a warning to other folks in the market for a new machine. Thanks!
