"Unable to open destination" - but SD is fine

Anonymous — Fri, 09 Jan 2026 11:21:40 +0000

Hello everybody! I'm having issues trying to bacukup a copy to new SD card. I could make an .img file from the previous SD no problem, but trying to copy it into a brand new SD gives the "unable to open destination disk" issue. The software has full access to disk, both SD work fine, and it does detect the new SD card when selecting the disk. However, two seconds after I select the .img file, this issue pops up.

Old SD is in FAT format, file size is 62 GB, new SD is FAT format, 64 GB completely empty. Any idea how to solve this? Thanks!

I have a USB Stick with Ubuntu Server 22.04 for Raspberry Pi (aarch64) installed on it. I am trying to back it up, and shrink the drive from a 128GB Drive to a much smaller file. I have the shrink option set properly in ApplePi Baker and when I start the cloning, It seems to shrink the partition and image filesize by barely anything. I have tried to shrink with both the stable version as well as the beta version of ApplePi Baker, and the cloned image just doesn't shrink. NOTE: I am saving the clone as a

.img

file, NOT a

.zip

file.

Could you help me figure out why ApplePi Baker is not shrinking it's clones?

Here is the output log from my most recent "unshrunken" image using ApplePi-Baker v2.3.0 (Build2), (Helper Tool version 1.9.2), on MacOS Version 15.3.2 (Build 24D81):

Does not recognize sd card as a source on Mac OS 15.1

Anonymous — Sat, 18 Jan 2025 19:47:49 +0000

Hello!

Fisrt of all, great tool!

I've just used it on Intel MBP with Mac OS 12 Monterey and works great.

However when I tried it on a newer MBP with the latest 15.1 OS Sequoia, it does not recognize the cd card as a source.

You can see the oputput from diskutils. The sd card is 64GB listed as /dev/disk8.

All permissions are set as documented in the startup window.

Overwritten external disk with bootable image - can I restore the old data?

Anonymous — Mon, 30 Dec 2024 20:57:09 +0000

Hi - this is my first time posting...

I was backing up a RPi image and accidently reformatted an external expansion drive with the bootable image, losing all the data in the process...

Is there a way I can restore the data on the expansion drive?

I wrote the retropi image to the external expansion drive with Apple Pi Baker.

Any help would be much appreciated!

Unable to open destination

Anonymous — Sun, 04 Aug 2024 16:30:07 +0000

Hello

Ive tried to make a Backup of my Raspberry 4 SD Card (which I did a lot of times before). The Backup didn't`t work as the pi want start any more with the backup restored on a SD Card. But the main thing is, also the original sd card (which worked before the backup) also didn't boot anymore. trying to restore the backup to a brand new card brings the error "Unable to Open destination diskX". MacOS Ventura 13.6.8, Apple-Pi Backer 2.2.3 (Build 1).

Can someone help here?

Thanx

Does partition shrinking/expanding work on an amd64 Version of Ubuntu?

Anonymous — Fri, 24 May 2024 02:25:13 +0000

I'm wondering if I can use my Mac with ApplePi Imager to back up my AMD64 version of Ubuntu to a bootable ISO on my Mac. On my X86 machine, I am running Ubuntu 24.04 Server and it is installed on a USB Stick. When I shutdown the Ubunutu x86 machine, and plug my usb stick with ubuntu x86 on it into my mac, ApplePi-Baker Beta backs up the Ubuntu USB stick to an IMG file just fine. HOWEVER, it will ignore the shrink/expand option, and thus, I have an extremely large img file with tons of empty space, just taking up space on my mac hard drive. I am wondering if ApplePiBaker (Non Beta) can successfully backup and X86 OS and shrink the IMG file while doing so. If now, do you have any other suggestions on how I can go about shrinking and then backing up a large USB stick with Ubuntu x86 installed on it, on a Mac? Please let me know if you have any Ideas.

Access Violation on startup twice before App shows up and cannot located Memory card

Anonymous — Sun, 17 Mar 2024 17:42:10 +0000

I am running the program on an Apple Silicon M2 equipped Laptop and recently upgraded to MacOSX version 14.4.

On advise from a good friend, I have already granted ApplePie-Baker full disk access but that unfortunately did not help. I keep getting this error (and twice!) when attempting to start the program:

ApplePi-Baker

Access violation.

Press OK to ignore and risk data
corruption.
Press Abort to kill the program"

After choosing to ignore the warning (twice!), and clicking "Select a Disk", I am greeted with an impressive list of non-existing disk alternatives, none of them being my SD card that under normal circumstances will show up as the only option here.

The last selection menu I saw was:

/dev/disk5 (4GB Apple Disk Image)
/dev/disk7 (9GB Apple Disk Image)
/dev/disk9 (17GB Apple Disk Image)
/dev/disk11 (5GB Apple Disk Image)
/dev/disk513(10GB Apple Disk Image)
/dev/disk15 (4GB Apple Disk Image)

Any clues will be appreciated - I am out of cues...

Access violation and general instability

Anonymous — Tue, 12 Sep 2023 14:48:36 +0000

I have to reboot my Mac Pro every time I want to use ApplePiBaker and it seems to have become rather unstable in terms of reliability of me being able to backup and then test restore images.

How can I help?

Setting the partition size when etching an image

Anonymous — Fri, 05 May 2023 09:20:11 +0000

Hi all, firstly thanks for the use of this application.

I have an SBC with a removable eMMC of 14.5GB. The difficulty is that the mass storage state of this board is very difficult to achieve (I’ve been unable to achieve it) so I use dd to copy working systems from the SD. I am unable to use a 16GB SD as that is too large for the eMMC.

Can anyone tell me is it possible to specify the target SD’s partition size to say 14GB so I can make use of the eMMC’s capacity?

Thanks in advance for any input.
