1. Can I mount Physical Disk with several partitions?
2. Can I mount totaly damaged RAW disk without valid filesystem? The disk must be accesed with external hex editor. Currently we can't use hex editor on unformated damaged disk.

It isn't possible. Perhaps it will be implemented in a future version.

Yes, you can.

Could you please describe the problem in more detail?

1. Mount some trash to disk "q:". Do not format it.
2. WinHex can't open disk "q:".

Let me remind you, that CallbackDisk is an SDK to create *virtual* disks which map the data in custom places and not necessarily on the HDD. If you need to have raw access to the existing disk, then you are looking at wrong solution.

We want to provide acces to virtual hdd (recovered raid in our product). Recovered raid can still be damaged, but can be fixed in manual mode using hex editor. As I can see callbackDisk don't work in this case.

I'll check it and answer to this topic.

With the current version it's only possible to create only one virtual disk for each physical volume. I.e. your code should parse partitions on the raid and then create CallbackDisk virtual disks for each partition.
And even if we implement such functionality what will it be if the partition table on a damaged raid still be corrupted?

This is a problem of WinHex. Seems it can't open disks in DASD mode. I've tried to open a corrupted flash card (the first sector had been wholly zeroed) and it also couldn't do it.
