STEIN@UCONNVM.BITNET (Alan Stein) (05/08/89)
After suffering with only 40 megabytes on my hard disk for months, I decided to bite the bullet, back up my hard disk completely and try to figure out why I was only getting use of 40 megabytes rather than the entire capacity, which is closer to 41 megabytes (wow, what a difference). Following the advise I've received on this board, I did another low level format and, checking with the formatting program from A2-Central, found that I had 82028 blocks, or roughly 41.014 megs. When I booted GS/OS, I got a message that the device was unformatted (meaning no high level format), so I tried formatting it then and got the telling message that "the file system won't use the entire capacity of the drive" (not the exact wording, but close), and it only formatted it for 40 Megs. I tried another low level format and then a high level format through Advanced Disk Utilities, with the same result. How have others managed to get more than 40 megs formatted? Would another low level format, followed by a high level format with Copy II Plus do it? (I wouldn't think so, since Copy II Plus is a Prodos 8 application.) Alan H.

Since ProDOS can only format up to 30 megs per volume, this is usually the alternate. I don't have a hard drive myself, but everything I have read about the bigger drives say you have to partition them into 2 or more volumes.

My Apple hard drive experance is limited to 20 meg's but I have a lot
of MS-DOS experance with hard drives.
There is a "small" item not covered in or by the salesman. Hard drive
overhead. Room required by the hard drive for operation. Some are
greatter then others. We use a MFM 140 meg hard drive that Preps
(low-level) then formats to 112 Meg. And thats ALL your going to get
out of it, then knock off for bad sectors and operating system.....
When you shop or check specs for a hard drive, watch for the FORMATED
capacity. Thats going to be your Play ground if you buy it...

Alan,
Did you try partitioning your hard drive with the Advanced disk
Utilities. Since ProDOS can only format up to 30 megs per volume, this
is usually the alternate. I don't have a hard drive myself, but
everything I have read about the bigger drives say you have to partition
them into 2 or more volumes. Your message doesn't state whether you have
tried this or not. Good Luck!

The ProDOS file system actually is the limiting factor here, not the whole of GS/OS. ProDOS had a limit of 32Mb, and therefore the ProDOS FST, which provides access to volumes formated under the ProDOS file system, limits the volume size to 32Mb. I suggest partitioning your hard drive into two partitions. You can do this using the Advanced Disk Utility on the /System.Tools volume.
