[Dorset] [OT] Android Tablet question

2013-06-21 Thread Tim
I have a Samsung Galaxy Note Tablet which I am getting on with OK but 
for one problem. I use Google Chrome for web browsing but it keeps bring 
up mobile version of internet pages, so rather than bbc.co.uk/news I get 
m.bbc.co.uk/news and to be honest it is annoying the hell out of me. Is 
there a way to stop the browser from saying it is a mobile device and 
being diverted to mobile pages??

Hi Charles,

 I have two (1+1TB RADI-1)=1TB network drives and two (2+2TB
 RAID-1)=2TB network drives (the set comprises main and backups), and
 one (1+1TB RAID-1)=1TB 4-way switch transferrable external USB
 workdrive (no data lives on PCs).

BTW, if that's with a hardware RAID controller then it's worth
considering what happens if the controller fails, especially when it's
aged a bit.  Getting a replacement that picks up with the drives where
the old one left used to be tricky, perhaps it's easier now?

Cheers, Ralph.

Thanks Ralph, looks like I am going to have to learn the correct google 
incantations for searching as well as linux cli incantations :(

Thanks Ralph,

I bought pairs of Lacie and Freecom external dual-drives with RAID  
controllers built in.


I asked Lacie what happens if the RAID controller packs up - could I  
transfer both disks to my other controller and they said 'NO, send it  
to us'.


I asked if one of the HDDs could be inserted as an added drive in my  
PC, and they said 'NO, RAID information lives on disk'.


I pointed out that the drives were RAID 1, mirrored, so no stripes or  
anything like that, and they still said 'NO, send it to us'.


Either Lacie were not being cooperative (which I think was the case)  
or they are not bog-standard drives with the same information written  
to both, which RAID 1 (mirrored) implies.


For data safety, I bought an extra HDD for each set, the principle  
being that ONE side of each set is periodically alternated with the  
spare. This does two things: the work done by each of the alternate  
set is only half when compared to the unchanged drive, so when the  
longest-worked (unchanged) drive fails, the other two, having only  
done half the work each, will survive the rebuild-new-drive process.  
Rebuilding is the hardest work a drive will do, and the surviving  
drive is normall expected to do it at the expected end of its own  
life! The alternating HDDs will also benefit from having most of the  
information already on them.


RAID does not deliver the data safety it promises, and may be no safer  
than a single drive.


Saving to one HDD then saving to another HDD while employing the one  
alternating regime would be better than RAID, but is just not  
practical. Saving to two HDD at the same time, with alternating, would  
be better - but can it be done?

Give us all your data!!!

RAID disks/partitions have a header, which in Linux RAID I believe 
includes the UUID of the disk and the UUID of every other disk in the 
RAID, ie. each disk contains the entire configuration of the array.


I wouldn't be surprised if their NAS box runs Linux and uses Linux RAID, 
as that would be cheaper than implementing their own, but it might not.


Anyway, unless they are trying to make life hard for everyone by storing 
the data in a non-linear manner you could simply ignore the RAID header.
The 'mount' command can be passed an offset, so you can find the real 
start of the filesystem on the drive (and there's probably many ways to 
do that) and pass that offset to mount.
