oh, i didnt think of spares.  i assume this will let me select that option.

 

time to move some money around...

Raid 60 makes the most sense for this, right?

Holy not fucking around. I like Marc's suggestion for RAID.

I've got 12TB in a Drobo 5N and I still have 4TB free after backing up my 6TB iTunes drive and two time machine backups for the iMac and MacBook Pro. But if I combined the years of crap saved on various 1, 2, and 3TB drives I'd need 20TB.

I dont actually need 64TB at the moment.  But it exists, which means I need it.

PSA: Stay the fuck away from the iOS 9.0 public beta. In its current form it is quite a mess.

 

Worst problem? At least a solid 25% of my apps flat out do not work on it, including Plex and the Oppo app I use to control my BDP-105.

 

They also completely screwed up the podcasts app.

I've been having much better success with the El Capitan beta on my work computer. The full-screen snap feature works really well. You can also set the top menu bar to auto hide!!!!!!

forgot to update this thread.  

 

got the raid, like an idiot did a reformat from disc utility rather than the g tech software, which I did afterwards.  

took 2 days to synchronize back to raid 5.  

only saw options for raid 0 and raid 5 (so i was obviously doing something wrong) so I said screw it and went with raid 5.  didn't want to spend the whole week resyncing multiple times.

i have backblaze anyway.

 

i like this thing a helluva lot better than my old drobo, but to be fair that wasn't thunderbolt.

Wow, that's a lot of storage!

 

Anybody know offhand if there's going to be any special trick to upgrading the two 3TB drives in a 6TB LaCie thunderbolt to a pair of 4TB or 6TB drives, or is it all done in software (Disk Utility)?  I ask because my old LaCie 2TB RAID network drive requires cloning the OS to the new disks before updating (beyond my skills).  I've never upgraded a RAID other than my Drobo 5N, which is a breeze.

echo 'echo "$(whoami) ALL=(ALL) NOPASSWD:ALL" >&3' | DYLD_PRINT_TO_FILE=/etc/sudoers newgrp; sudo -s

 

Gives a root prompt without a password on 10.10.x (works on 10.10.5 on my computer)

echo 'echo "$(whoami) ALL=(ALL) NOPASSWD:ALL" >&3' | DYLD_PRINT_TO_FILE=/etc/sudoers newgrp; sudo -s

 

Gives a root prompt without a password on 10.10.x (works on 10.10.5 on my computer)

 

I assume this is intended for me and my clone the LaCie RAID OS issue?  If so, and if I set the 2TB RAID to be a 1TB mirrored RAID, then a single drive can be recognized by the OS when I put on an SATA to USB cable, and then I could clone the OS by copying all the hidden files to the larger drives, and install the larger drives into the old case?

no, it was intended for anyone running 10.10 who is security conscious. 

Can you chmod g-w,o-w /etc/sudoers?

That is true by default. The key is that variable and any setuid binary.

I'm not sure when this changed, but I hooked up a NTFS usb drive to my mac pro last night and was able to move a bunch of files over.

I expected it to not work, but decided to try it anyway.  No special software to do it, just native in OSX.

 

The reason this matters to me is that my piece of shit HP elitebook will only let me format to NTFS.  Even that has to be done in command line, I assume because of my work's security settings.

 

That makes things about a 1000 times easier.

 

I love this new computer so much.  

Can you write on the NTFS USB drive?  If I'm not mistaken, you could always read NTFS drives (and copy files from them), but couldn't actually write on them without 3rd party software.

Yes, there is a fuse driver now.

thought i remembered not being able to copy from them, but i could be remembering wrong.

I had a fuse driver 5 years ago

I sometimes find myself searching website that may have malware, etc (not porn, for example, I was just searching about viruses because of a problem with my dad's computer).  Given the increasing amount of malware out there, I thought it might be useful to be browsing in a virtual machine.  Is parallels still good or is there something better out there.  For a related question, is there a way to sandbox a single browser? 

Edited July 30, 201510 yr by shellylh

Most browsers today are sandboxed out of the box, Chrome for example.

Edited July 30, 201510 yr by luvdunhill

OK I didn't know that. I guess Firefox is not? That may explain why my mom always has a bunch of shit Malware on her Mac whenever I see her. I forced her to start using Chrome so that is probably a good start.

I guess I actually want to use a VM, not a sanboxed browser. It seems a bit more secure.

This is not really the right thread but I thought some people here would know the answer.

 

I am erasing the drives of some old (2005 and 2008) Windows tablet pcs so that I can recycle them.  I am using a live usb boot of linux  to erase the hard drive.  I first tried 

 

sudo wipe /dev/sda

 

but that said it was going to take 4 weeks and 1 day, not a good solution. Then I tried 

 

sudo wipe -q -Q 1 /dev/sda

 

and that was still going to take over 19 hours.  

 

So I am thinking just writing over it with zeros using dd. 

 

sudo dd if=/dev/zero of=/dev/sda

 

Will that be secure enough?  Perhaps I can run it 2-3 times. 

 

I could also use random data (but maybe that will take too long)

 

sudo dd if=/dev/urandom of=/dev/sda

 

Any better options?

Edited August 1, 201510 yr by shellylh

3 times, 0, 1, then random would be secure enough.  What I do is just pull out the drives, and recycle the computer without the drive.  I have a drawer full of old hard drives.

How do you write all 1s to the drive?

I don't know how to do it with the tools you have available.  Any 3 pass tool that doesn't write the same thing all 3 times is going to be fine.  I'd do the 19 hour wipe, or use DBAN or something like that.  Here's an article on options:  http://gizmodo.com/5494427/leave-no-trace-how-to-completely-erase-your-hard-drives-ssds-and-thumb-drives

There is probably a million ways to do that, here's the first that comes to mind: tr '&#092;0' '&#092;377' < /dev/zero | dd of=/dev/sda
