udisksctl unmount -b /dev/sdXY udisksctl power-off -b /dev/sdXExample if my drive is /dev/sdb1:
udisksctl unmount -b /dev/sdb1 udisksctl power-off -b /dev/sdbSimilarly to above, power-off can be used to detach the drive even if there are no partitions mounted, or no partition was ever mounted:

LTO Motorcycle Registration 2023 for less than a year old
Last November 2022, I bought a new motorcycle. It was registered by the dealer two weeks after then got my certificate of registration(CR) and official receipt(OR) on mid January. My plate number ends with 7 (e.g 127ABC).
As per LTO FAQ on Motor Vehicle Registration registration schedule :
1 - January 2 - February 3 - March 4 - April 5 - May 6 - June 7 - July 8 - August 9 - September 0 - October
Which means that I should make my renewal by July and not November. I such cases LTO will only extend the validity of the registration for another year.
Requirements :
For smooth transaction, prepare the following :
PHP 5 : 2 photocopy of OR and CR (1 for CTPL and 1 for LTO) PHP 302 : Insurance(CTPL) I got from Cebuana which is the cheapest that I know PHP 202 : LTO fee ==================== PHP 509.00 : Total expense
Not Required :
It will be a waste of time and money for the following as they are not needed.
Emission test (which cost at least PHP450) Stencil of engine and body number
Steps : 1st try (Failed due to No CTPL)
You can skip this if you have the mentioned requirements earlier.
1) Reception
Present OR/CR photocopy then consolidate it with the given queue/number and noted that it is for adjustment. Below is my copy of my first queue number.
Was advise to go to window 5
2) Window 5
Was advise to go to acquire CTPL first. My queue number was also discarded.
3) Cebuana
Purchased CTPL
Steps : 2nd try OK (with complete requirements)
1) Reception
With my CTPL and OR/CR photocopy I was advise to go to motor vehicle inspector for inspection
2) Motor vehicle inspector
Visual inspection of motorcycle then consolidate my documents with his form.
It is located in a "kubo" just outside LTO Ligao. If I'm not mistaken this is Window 4 in queue number.
3) Reception (around 10:30AM)
Go back to get my new queue/number
4) Window 5
Pass the documents and form.
5) Window 10 (Cashier)
Paid PHP202.
6) Window 3 (Releasing)(About 10:50AM)
I've got my OR :
With complete requirements, It can be done in less than hour in LTO Ligao.
Let me know your thoughts on this.
