Is there any charge to have these questions answered or to use technical support (pre-sales and post-sales)?

There is no charge, but the support for demo users is limited.

Will all files/folders be recoverable from a corrupted partition and logical structure if they appear during the initial scan from the demo disk (assuming the pro version is purchased)?

It depends on how the partition was lost, and if the Master File Table (MFT) was corrupted when the partition info was damaged. Also, if the partition was quick formatted, the original data may show but will not be recovered when the partition is. In that case (quick format on a partition) we recommend using file recovery. It will recover the files to another, healthy partition.

In the above scenario, how do you know if the MBR needs to be recovered and restored or if the issue is limited to the partition and logical structure?

If the MBR needs to be recovered the program will tell you (disk needs to be initialized) and it has the ability to initialize a drive (tools-> fix mbr).

Does the Master Boot Record also contain the Partition Table(s) and Boot Sectors? Or are all three items saved by Active Recovery under one filename?

The MBR contains the partition info, not the boot sectors.

Does the DOS version restore file names and folders to their full length not truncated to 8.3 length? What about the Windows version?

When a partition is recovered by either dos or windows the names of the files will be unchanged, assuming the Master File Table was not damaged.

After a partition is restored will the partition, folders, files and programs be fully accessible in windows?

Yes, again assuming the MFT is healthy. Sometimes it is damaged in a slight way that we do not see, but windows does. If the files are not visible after recovering (which happens a small portion of the time) and they were visible to partition recovery, sometimes running chkdsk on the volume will fix it. In general, if ONLY the partition info was damaged, and the file structure was not corrupted, the entire file structure will be recovered.

Given that the Active Recovery program is a "fix", do I need to reformat the drive in order to protect the integrity and stability of it after the partitions have been restored and the files/folders have been backed up?

It is always a good idea to back up the files, but there is no yes or no answer for that question. The software does not know what caused the problem and can not stop it from happening again. If it was a one time thing it will not make a difference.

What is the advantage of the bootable Windows CD (Enterprise edition) if your computer can boot to Windows on a spare HDD and you purchase the pro version?

There is no advantage. The boot cd is for computers that can not boot into windows.

What operations on a system and data partition can only be accomplished in DOS, not in the Enterprise Windows version?

The windows version can do pretty much anything the dos version can. The dos version is not used much now that we have the bootable windows version. The dos version can ve used on older computers that can not boot into windows. Not a lot of people use the dos version but we keep it around for the few that need it.

In regards to MBR and partition recovery and restore, how does Active Recovery compare to the competition e.g. Partition Magic and Paragon Software?

I do not know. I do not use them.

Will Active Partition Recovery for Windows restore a USB flash drive (i.e. Memory Stick) that has been low level formatted (i.e. formatted to prevent data from being recovered) and as a result is no longer useable (cannot be formatted or written to)?

No. File recovery may be able to recover the data, but partition recovery can not help if a drive has been formatted. (Sometimes it can help if the drive was fat32 and formatted NTFS and vice versa, but it can not help if the disk has been formatted, quick or full, using the same file system). Partition recovery only recovers the partition information, and formatting overwrites file system info (file tables used / unused space etc).

Are all of your products fully compatible with all versions of Windows 7?

Partition recovery for windows runs on windows 7. The dos version may not run.

Does the utility that creates a disk image run in Windows? If so, is it also limited to a maximum file size length of 2GB like the DOS version?

The utility runs in windows and has no size limit. The dos one only writes to fat drives so it splits the disk into smaller chunks, as fat32 has a file size limit. The dos version can image a 100 gig drive, but you will have 50 2 gig files. The windows version can either make it a single file or split it into smaller files. If you were saving the image to a fat 32 drive, even with the windows version you would need to split the file into chunks due to the fat32 file size limit.

When scanning for deleted, corrupted or damaged partitions, how do you remove a partition and logical disk structure from the list before you save the MBR, partition table and boot sectors?

When you same the MBR it does not save the list from the scans. It only saves what is in the MBR.
