Using a DD'd System6 backup in BasiliskII/vMac?

[LittleJackal]

Hi all,

Apologies if there's already a thread on this, my preliminary search wasn't helpful. 

I have an SE/30 that I am currently re-capping and cleaning. It was loaded with software and I'd love to back that up and archive it. My plan was to pop the SCSI drive into a Linux machine along with an old 50-pin SCSI card and just do a dd dump to an image file. 

My question is, are images like this usable in Basilisk? If so I can probably get TCP/IP working fairly easily and get the data off fairly easily. Heck, there may be a way to mount HFS in Linux and just get the data off that way, but I'd like to be able to play with the disk image if possible.

Anyway, mostly curious. I'd hate for the drive to die and take all the data with it, given how it's fairly old now.

This is a very rusty memory, but I'm fairly sure that you'll be able to do what you want if you make your disk image the right way. As I recall the key to success will be to use a Linux kernel that has Apple Partition Map support available (don't think that will be an issue anymore, it could be when I first mucked around with BasiliskII back in the late 90's) and for you to DD the specific partition that has the OS and data on it, not the whole raw device. If you do the latter I'm pretty sure Basilisk will be lost and confused because it essentially maps all volumes through a skeleton floppy driver that doesn't read partition maps and therefore won't see the file structures it expects.

... but also, that said, I think you'll have to use vMac instead of Basilisk II if you want to actually run the OS installed because I don't believe Bas supports System 6.

Basilisk II only runs in 32 bit mode. You'll need to run MVM or some othEr emulator.

if you use DD, you want to DD the partition and not the whole disk or the emulation wont understand the file. 

I have already successfully done this with an LC475 drive that was dying. DD the partition, change the img to hfv or hfx, and everything is fine.

Thanks for the help everyone.

Going to try this tonight or tomorrow. SE/30 no longer boots (recapped, and still get folder with question mark) so hopefully the disk isn't too far gone.

the HDD is likely toast depending on what model it is.
