Standard, Extended, or DOS disk

Post by starfiretbt »

When creating a new hard disk volume in sheepshaver there seems to be an option of standard, extended, or dos. Which one should be selected? From what I looked up online it looks like standard is an older format while extended is a newer format. Does that mean for games that are old use standard and games that are new use extended? I also assume Dos is for dos files, am I wrong?

Also I have been divided over something involving forum etiquette. If someone helps me should I post a thank you? I used to do that then I thought it would show a reply and the helper would have to spend time out of their day checking it out so maybe the kinder thing would be to let the post conclude.

System 7 through MacOS 8.0 can only use Standard format (HFS).
MacOS 8.1 and later can use both Standard and Extended format (HFS+). The extended HFS+ is then the preferred format, especially for larger disks.
DOS used to be for compatibility with non-Mac computers. Better not use it in the emulators. Most Classic Mac files will not survive on a DOS disk.

(No need to post 'thank you', unless it provides information, like that a discussed problem was solved.)

Also, HFS (not HFS+) has a maximum total drive size of 2GB, at least on real hardware.

At least applies when using the 630 rom in Basilisk I presume (had a real Quadra 630 back in the day).
