Re: [MiNT] Need help to resurrect a Falcon + CT60

Unfortunately, that seems to be the case. /dev/sda7 accesses the whole partition, not a file in it. You probably wrote the contents of your Atari disk over your PC partition, corrupting it.

I see. Be very careful, dd is not a tool for daily work, its easy to mess your whole system up with it. You should always be alarmed when you have to use "sudo" to execute a command, if in doubt better ask once more.

Basically, what you have to do is copy the harddisk image of your Atari (or a single partition on it) to a regular file on your linux box. You don't have to (and must not) write it to a partition. You only need that partition if you dont have enough space in your home directory (which is probably the case when booting from an usb stick). So you need to mount that partition first (ie mount /dev/sda7 /media/jean-luc).

However it sounds that using Aranym might be easier in your case.

I don't konw how far it has achieved, but I lost many files at random places. Some are not that important, but others are and I hope these weren't affected.

Next step will be to give the Falcon's drive another try, but on another place - a blank 64 GB stick, for instance -.

you made several wrong assumptions:

dd doesn't work on directories -- it works on handles, devices, files but not directories ... and it copies devices as whole (as an image), not file by file

you can't access windows disk/directories like /dev/sda7/ ... first you have to mount the device/partition (/dev/sda7) somewhere so the kernel knows its filesystem and structure

sudo really means "superuser operation", i.e. something you definitely shouldn't do as a normal (inexperienced) user ... it's not like windows uac which everyones just confirms without thinking

you thought you'd be careful when typing the name of the disk with your precious data as you say

So you see, you tried something incredibly dangerous without proper advice/confirmation, that was really asking for trouble :-( Fingers crossed for your recovery attempt, though.

Always know what are you doing with tools like dd else you may end up with huge data losses!
