[raspberry-vi] Larger memory cards, a request

Hello list,
I don't have any SD cards bigger than 8GB.
I need to get a sample of the 'parted' output for larger cards.
This is because I want to write a new version of the expand-rootfs
script which expands the file-system to within 10 megabytes of the end
of the card but not right up to it.
On my 8GB cards this is the output of:
parted -s -m /dev/sdc -- print
BYT;
/dev/sdc:7960MB:scsi:512:512:msdos:Multiple Card Reader:;
1:1049kB:95.4MB:94.4MB:fat16::lba;
2:95.4MB:1878MB:1783MB:::;
5:96.5MB:1878MB:1782MB:ext4::;
(the -m switch produces machine parseable output).
I need particularly to know if, for larger cards, does the second field
of the second line read differently. Does it show 'GB' instead of 'MB'.
On the above it is:
7960MB
The reason for this is that when the root file-system is expanded to the
very end of a card, backing up the card to a .img file and then writing
it back to a card sometimes does not correctly reproduce the far
boundary of the file-system and backups become useless.
I need to parse the output above with Perl and calculate where to end
the file-system expansion.
So if somebody has, for example a 32GB card, can they please paste the
output of 'parted -m' in an email.
Thanks.
Mike
