Hi hackers@
A new purchased HP laptop (pavilion entertainment PC dm3
http://reviews.shopping.hp.com/8843/dm3t_series/hp-pavilion-dm3t-customizable-notebook-pc-reviews/reviews.htm
had all 4 partitions occupied with Windows 7 Home Prem OA.
(Maybe the shop did that)
I want just 1 of the 4 fdisk partitions with an MS slice (for h/w
test mainly), & the other 3 with FreeBSD slices (2 boots of different
release & a large common UFS as usual. I've done that often before,
not asking for help on that, but normally the PC just uses a single
fdisk partition so it just a case of shrinking it & allocating the
other 3.
This is a bit trickier, I need to figure what all the other partitons
are for, & how to merge/ remove them down to one.
So first I shrank the main NTFS from 223 G to 65G (for now) &
rebooted MS & it still boots MS,
Next I need to copy data from spare Fdisk F1, F3, F4 partitions to main F2,
leaving the others free for FreeBSD (& also I'll need to tell
Fdisk precisely how big my new shrunken F2 NTFS is).
Maybe one of you has insight what the partitions might be for at present ?
It has a 200M F1 active, then F2 is the main MS FS of most of disk.
I wonder why they do that ?
For recovery or repair ?
Or to later allow an encrypted F2 OS booting from another
smaller F1 OS first ?
I wonder if I can safely merge F1 & F2 ?
Then on F3, HP used 12.6 of 15G for their own software as hardware
manufacturer. (Stuff I'll want to move to F2, cos I need
partitions for BSD) Not sure how I'll move that tree (tar
I guess as I dont know modern MS or trust any MS) (maybe
insert a join command if MS still have that (opposite of
mount, effectively) to keep the HP seperate yet have paths
under MS working.
Then F4 is taken too,
Backup stuff maybe, or suspend ?
My notes chronologically as I worked:
--------------
MS My Computer says
Local Disk (C:) 176 Gig Free of 218 GB
RECOVERY (D:) 2.39 GB Free of 14.5 GB
HP_TOOLS (E:) 92.5 MB Free of 99.1 MB
Boot a USB image
fdisk /dev/ad4
Partition 1 Sysid 7,NTFS etc 199 M Active
start 2048 size 407552
Partition 2 Sysid 7,NTFS etc 223305 M
start 409600 size 457328640
Partition 3 Sysid=7,NTFS etc 14866 M
start 457738240 size 30445568
Partition 4 Sysid 12,DOS/Win-95 32 bit FAT 103 M
start 488183808 size 211312
The numbers above add up OK

Analysis with dc shows F1,F2,F3 fdisk partition entries each 2x512
bytes more than df shows as size, but with F4, The DOS FS within
the fdisk partiton is considerably smaller:
