trk2usb is a utility to transfer your current Trinity Rescue Kit to a USB medium or harddisk.
When given without the noformat option, it will destroy all data on the destination device, create a fat filesystem in the 4th partition id of the disk. This gives the best compatibility with most BIOSes.
It is also possible to do a non-destructive transfer to your medium given the -n option.
The destination medium has to be at least the size of the TRK isofile. Recommended is 256Mb minimum.
trk2usb -d [DEVICE] -s [SIZE] -n
Specify the destination device. In case you use it without the noformat option, you need to give the complete disk as argument, not a partition. Your disk will be erased, zeroed out and formatted with one partition as FAT16 of maximum 1Gb as the 4th primary partition. This is for maximum compatibility.
Example: trk2usb -d /dev/sdc
Noformat. Use this option if your device is already correctly formatted and you don't want to lose your data on it. This requires you to specify the destination as a partition.
Example: trk2usb -n -d /dev/sdc1
Optionally, you can specify the size of the destination partition in Mb. This allows you to add more partitions later. This option is not combinable with -n
