Title: CF memory card as HDD - lost partition?
Post by: kreciu on June 13, 2016, 01:53:14 PM
I was playing with ShapeShifter and I tried to create hard disk file and I forgot that size of file was set in kb so I make it larger then my partition... I got error that there was not space on hdd. Great. I deleted file that was created... tried to create another one, but ShapeShifter started to "behave funny".

After reset I lost two partitions, and after another one my CF card completely was gone. Computer will not boot with it :(. Need to buy new one.

Question: HOW TO PREVENT THIS KIND OF STUFF happening! (I still love Amiga, I think).

Why do you need to buy a new CF? How about doing a re-partition/quick format instead?

The only reason you've lost data is because the CF couldn't have been setup correctly in the first place (was it correctly dealing with standard Kickstart 4GB or 8GB limits?). Do you know what file system was used and what the partition sizes were? If it wasn't setup correctly then creating a huge file that fills the partition could wrap around and erase the beginning of the disk...ie your boot partition).

Computer will not boot with this CF card anymore.

FFS from OS3.9, largest partition was 600Mb.

How to set up CF "properly"? I did not have any issues with it before.
