Hi,
I noticed that DriveSetup fails to initialize partitions with the dosfs
(dos/windows file system, FAT32) when the partition is larger than
32GB (It's 38 GB here, and I want to use BeOS to initialize it :-)
Further investigation showed that DriveSetup uses add-ons
contained in /boot/beos/system/add-ons/drive_setup/fs
to do the job, but the "dos" add-on executes the mkdos
program, which failes.
| $ /boot/home/config/be/Preferences/deviceSetup
| will not prompt for confirmation
| using a 32-bit fat
| geometry: cylinders = 1, sectors = 80019765, heads = 1
| BIOS geometry: cylinders = 1024, sectors = 63, heads = 255
| mkdos error: Calculated sectors/cluster too large (128).
| Try using a larger sized FAT
Since FAT32 supports drive sizes up to 2 Terabyte,
I decided to write a replacement of mkdos. The core
functionality should be finished by tomorrow. Calculation of
sectors/cluster is already working fine :)
usage: mkdos [-n] [-t] [-f 12|16|32] device [volume_label]
-n, --noprompt do not prompt before writing
-t, --test enable test mode (will not write to disk)
-f, --fat use FAT entries of the specified size
The remaining problem is evaluation of arguments,
which I never did before. I hope somebody can help me,
By the way, this is the way it is used by DriveSetup,
but I would like to have it working from the shell also.
argv[1] = -n
argv[2] = -f
argv[3] = 32
argv[4] = /dev/disk/ide/ata/1/master/0/0_0
argv[5] = daten_1
A few remaining questions, to be answered by the Preference team:
Anyone already doing this? Should I stop? Are you working on a
DriveSetup replacement?
regards
Marcus (media kit team :)
PS:
I need some volunteers to test it, once it's finished.
