Re: Green Light No Longer Blinking When Power Down

The newest Raspbian Jessie full version still does the 10 flashes on shutdown. Not on my machine. It has a fairly clean install of the latest Jessie full version, and last I checked, no blinks after a 'sudo halt'. I'll give it a play this weekend. Not sure if you can try "sudo shutdown -h -P now" c...

Re: Green Light No Longer Blinking When Power Down

I've just installed that (Raspbian Jessie Lite) image on a Pi 2B and it still does the 10 flashes when I run that command. Did you do anything else, other than just install the image? I'm now trying apt-get update/upgrade to see if that makes any difference... no, still does the ten flashes. Hi, th...

The newest Raspbian Jessie full version still does the 10 flashes on shutdown. Haven't tried the full version yet as it takes time to download. (Slow internet speed here...)

Re: What is Pi Optimum Operating Temperature for 24/7 Operat

You've got good temperatures there. Nothing to worry about. :) The Pi is set to slow down if it ever reaches 85°C (The chip has actually been tested to over 130°C, but that isn't a good temperature to run at). If any of mine reached 65-70°C I'd be surprised. Basically, heat isn't something you have...

For those who might doing same stuff like me, here is how i fix the issue. 1. Guess this is really an out of memory issue, some how Pi runs out of memory when installing RSQLite package. So you have to increase swap file size to prevent the out of memory error kicks in. 2. Type in command "sudo nano...

Is mkfs equivalent to e2fsck?
No , only fsck is synomymous with e2fsck.

mkfs makes filesystems , it destroys everything which was on the disk beforehand. fsck is filesystem check , it should not
destroy anything.

Thanks for the info. I'll stick to e2fsck for now.

Re: Using Raspberry Pi to Fix External HDD

if your disk crashed and burned your data then I would suspect what it was connected to then the best way to test your disk is to repartition it as ext3 then format it with checking ... i.e. mkfs.ext3 -c /dev/sda1 and see what that says if you want to format it as ntfs then I would do it on a windo...

The ntfs-3g project still advises you to use Microsoft tools with NTFS drives : man fsck.ntfs ntfsfix is a utility that fixes some common NTFS problems. ntfsfix is NOT a Linux version of chkdsk. It only repairs some fundamental NTFS inconsistencies, resets the NTFS journal file and schedules an NTF...

Re: Using Raspberry Pi to Fix External HDD

What happened to this disk? How old is it? If it has been dropped or it's well used then it would probably be best to replace the disk. 500GB will cost less than £40. The chances of losing another 500GB of data would put me off using that disk for anything but temporary storage. I think there was a...
