[ts-7000] making a new Debian Linux micro disk from an old one, with busybox linux.

["Jon L" <>]

Ok I have a TS-7500 and it has on its 2GB Micro SD card 4 partitions and a 
bootable Debian linux.  The TS-7500 boots to Busybox Linux and from there I can 
umount the SD card and see its partitions:

# fdisk -l /dev/nbd0

Disk /dev/nbd0: 549.7 GB, 549755813888 bytes
1 heads, 62 sectors/track, 17318416 cylinders
Units = cylinders of 62 * 512 = 31744 bytes

     Device Boot      Start         End      Blocks  Id System
/dev/nbd0p1               5       42282     1310592   c Win95 FAT32 (LBA)
/dev/nbd0p2           42282       42348        2048  da Unknown
/dev/nbd0p3           42348       42414        2048  da Unknown
/dev/nbd0p4           42414       59326      524288  83 Linux


so now I want to make a new Micro SD card with these same information with a 
slight twist; I only have a 1GB Micro SD card.  No real problem as I don't 
really need the FAT partition so I can take away from that.  So I install the 
1GB Micro SD card on the thumbdrive and plug that into the USB port of the 
TS-7500, and make up the 4 partitions on the /dev/sda device:


# fdisk /dev/sda
.
.
.

Command (m for help): p

Disk /dev/sda: 1015 MB, 1015808000 bytes
32 heads, 63 sectors/track, 984 cylinders
Units = cylinders of 2016 * 512 = 1032192 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sda1               5          20       16128   c Win95 FAT32 (LBA)
/dev/sda2              21          23        3024  da Unknown
/dev/sda3              24          26        3024  da Unknown
/dev/sda4              27         560      538272  83 Linux
Command (m for help): w
The partition table has been altered!:

# fdisk -l /dev/sda

Disk /dev/sda: 1015 MB, 1015808000 bytes
32 heads, 63 sectors/track, 984 cylinders
Units = cylinders of 2016 * 512 = 1032192 bytes

   Device Boot      Start         End      Blocks  Id System
/dev/sda1               5          20       16128   c Win95 FAT32 (LBA)
/dev/sda2              21          23        3024  da Unknown
/dev/sda3              24          26        3024  da Unknown
/dev/sda4              27         560      538272  83 Linux



Now for the question:

Using the busybox linux, how do I get the contents of the 2GB's 3 partitions to 
the 3 partitions of the 1GB card?


This is assuming that my partitions are acceptable, so if my partitions are not 
right please help me with them, I couldn't figure out how to make partitions 2 
and 3 exactly 2048 like in the original 2GB micro SD card. 

TIA,
