If you have the gate on the floppy disk (do not confuse with the hole on the left side) open and it still writes to the disk then you have a problem I haven't had to deal with in 15 years. If it used to work and now doesn't then its the drive. There is a metal arm that "detects" the open gate, could be it isn't free to more or the spring is missing or damaged. If its never worked some PC BIOSs allow you to modify the locking mechanism. This could also be caused by a damaged or intentionally modified floppy drive cable. Back when software was distributed on floppies people who had to duplicate disks would disable the write protect feature. This allowed them to write on protected disks without having to go thought the timely process of setting the protection off to write then back on to send to users.

It won't let me open a password protected disc

very simple , if you have just deleted/unistalled a software which locks/password protects the system then you must reinstall it . Secondly you make sure you unchecked all the software functioning options inside when you open it now . Lastly try unlocking the system using the same software given capability to unlock if there is one (try several times if it doesnt work the first time), if it doesnt work then try unistalling the software again manually reinstall option given by the software and not through the control panel ,So then restarting the system and then see if its unlocked now.

Is the external overload connect to the nurture line can protect the compressor?

if your compressor is shorted to ground then you need a new compressor. if you need help finding what compressor part# you need let me know. The external overload is there to protect the compressor from overheating, but if it doesnt work there is no protection causing compressor to possibly short to ground.

My flash drive kingston 8 gb is write protected. how can i open my flash drive?


Try these steps.

Carefully switch the write protect tab to Write enabled when inserting the flash in the usb "PC".

try using it. This happens mostly when you are inserting the usb, the tab is pushed to Protected mode without noticing.

If that doesnt work, i suggest you buy a new flash from different brand and less GB.

Good Luck
