How to backup a SCSI2SD card?

[Michele31415]

I want to make a backup of my SCSI2SD SD card.  What's the best way to do this?  Can I just plug the SD card into my PC and copy&paste its contents to my hard disk there?

You basically need something like 'dd' to image the whole SD card, assuming it's formatted as an Amiga drive (as other operating systems can't read the file system generally (though Linux can read FFS if you have the module enabled).

If you use WinUAE (and maybe other Amiga emulators but I've not tried) you can mount Amiga formatted disks and the emulated Amiga can mount them. You could then use that to back up the contents to a hardfile on your PC's storage.

Thanks very much for the suggestions.  I'm not having much luck so far but I'm still working on it.  Is WinUAE able to mount a bare SCSI2SD SD card?  I thought that the SCSI2SD provided the translation needed for the Amiga to see a particular block on the SD card as a virtual SCSI device.

I also tried using dd on my Ubuntu in Virtualbox but it doesn't even see the card, although it sees other USB devices.  Same problem on my Solaris machine.  I tried using a dd program for the PC and that didn't work at all.  That's where I am now.

You can use Win32DiskImager to make backup copies of memory cards.

To restore such an image you need a card which is at least the same size as the image. You cannot shrink the size onto a smaller card.

Exactly how I do it. However you are incorrect on shrinking. The latest version allows for shrinking if card is smaller.
The RDB may not like it, as it will think it has more space than it has.

Spose shrinking is best used in linux situations, as you can get away with it.

OP, could also, just use WinUAE imaging in HDD selection screen. I have used this before and then win32imager to transfer to card.

It's impossible to shrink the partition size without knowing the file system structure. All a program like DiskImager can do is to stop writing at the end of the card. You will lose the data which has not been written to the disk. In most cases you will lose all data because file systems refuse to mount if the end of the partition cannot be accessed.

Ah!  Thanks very mcuh.  That looks like exactly what I needed.  It's copying the card now (at least it says it is).  It's pretty slow on my old XP machine but I don't  need to do this often.

AOMEI's Partition Assistant ( free version 9.4) can copy a partition like the Linux DD command to an equal sized partition or larger.
