Title: Nuked my darned hard drive.
Post by: Angus on August 25, 2006, 10:43:10 AM

I seem to have trashed my sys partition (DH0) and probably DH1 too, when I tried to format a partition from within Shapeshifter last night. The partition in question was towards the back end of a 40 gig drive, and it seems that Shapeshifter is not aware of large hard drives and so wrote over the data in the first 4 gigs.  :(

It shouldn't be a problem as I have a fairly recent Quaterback backup. But in order to sort that out I`ll probably boot from a WB 3.1 floppy, and then reformat the drive and use HDTools and Quarterback to recover my OS3.9 Workbench.

Question:
Will this method miss any special "unseen" hard drive files that OS3.9 needs to access the greater than 4 gigabyte drive etc?

I'm expecting to have to mess about with IDEFix but are there any other issues?

Cheers.

My my, that is really messed up...

Don't you have a emergency disk? That would be the easiest way I guess.

Like I told you in a different topic you should use hardfiles on a partition with SFS. That is as fast or faster compared to a dedicated partition. Also no problems like this ;-)

Thanks for pointing that out.  :)

(Also thanks for that prefs file - but no progress)

But back to my original point about, hidden hard drive files? Anybody?

Cheers.

OS3.9 doesn't "hide" any files to access beyond the 4GB barrier. It patches scsi.device (if you use it) and FastFileSystem so you can use devices larger than 4GB without experiencing the "wrap-around" effect.

The safest thing to do would be to boot from a Workbench 3.9 Emergency Disk and your OS3.9 CD so you get all the ROM patches, then use HDToolBox and Format on the OS3.9 CD to create and format the partition. Then run Quarterback (still booted from the Emergency Disk) to restore your backup.

Thanks - I've lost some stuff which is annoying, but all seems to be pretty much sorted.

Yeah, basically I felt I was embracing enough new stuff without really wanting to get into anything else, until I had the emulation side functional. Plus I used Fusion a few years back and it was happy on its own partition, but that was probably a small hard drive.

Anyway, SFS is it fairly straightforward to use?

Yeah you just add SmartFileSystem in to the RDB (with HDToolBox) and then change your partitions to the DOSType identifier for SFS, then format them. It's all covered in the SFS docs.
