Re: permission denied on a flash drive
Hi Mike, I have run into similar situations and have had some luck recovering locked-out flashdrive files using a live distro like Puppy, (Macpup 525 was the last version I used). I've tried to access these files using the file browser as root, (sudo nautilus in Mint) but for some reason the root user is not generally allowed to change file permissions on USB drives - a security thing I imagine. I'm sure there's someone here who can tell you how to do it though. Stu On 05/05/2012 08:43 PM, Michael Havens wrote: I got a flashdrive and I plug ot into a computer.

Re: permission denied on a flash drive
well... the pendrive was for backups. I just reformated it with gparted.. Hopefully that will fix it. Let;s see! . . . yep that fixed it! sorry I didn't think of reformating it before I posted that question. But that brings up thequestion. what If I needed the data on the drive? How would I recover it?

Got a good one here: Paul's printer paradox
I have a buddy name of Paul. He has a new scanner/printer thing by Brother, an MFC-9325CW. I got all the drivers off of Brother's site - he's running Mint 12 32bit (similar to Ubuntu Oneiric). I have everything working, but there's a quirk in the scanner (USB connected, where the printer is wireless). When I start xsane it throws a permissions error. The cure is to first, do an lsusb like so: sharon@sharon-Compaq-Presario- CQ50-Notebook-PC ~ $ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 002: ID 04f9:029f Brother Industries, Ltd Bus 004 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser THEN, based on the bus and device ID, I have to craft a chmod command - in the above case, like so: sudo chmod a+w /dev/bus/usb/004/002 I can then start up xsane and it works great. BUT, I get different USB bus and device IDs at every boot, so...this isn't a persistent solution. Right now I have an ugly hack in there: in their taskbar icon for xsane I added gksudo first, to run xsane as root. This too works, so long as you agree to xsane's severe warning against the practice. What I need is a quick script that runs lsusb, queries the bus and device IDs for the line with Brother in it, and then spits that out into a chmod command and then runs xsane. Package that as a desktop icon and call it good, right? Or is there another persistent way to skin this cat? If it was just for me, I'd say screw it and just run lsusb and chmod when I want to scan (which for most folk isn't that often) but...they're not real geeky... Help? I've BCCed Paul on this :).

laptop battery cycling
For the record, I'm running a Lenovo T420i with a 6 cell battery. In the past I've been told that it's bad practice to run a laptop on AC with the battery installed because it would cause reduced battery capacity. This raises two questions. First, is it true that laptop batteries don't have overcharge protection, and second, how many cycles is a battery like mine good for? -- Bob Holtzman If you think you're getting free lunch, check the price of the beer.

Re: laptop battery cycling
My VERY limited understanding is, the problem isn't overcharging exactly. It's that Li-Ion batteries are weird. They last longest when charged between 50% and 80% - as opposed to 100%. But bad news: maintaining the battery at a level below 20% is just as bad as keeping it at 100% if not worse, so...leaving it out really isn't a good solution either. What we REALLY need is a switch or setting in the laptop that will cause a 100% charge when you know you'll need more battery life soon, otherwise the default charge level is maintained at around 75%. But that would confoose too many people...might be a good FOSS project for geeks though? Failing that, the best solution is to leave it in there. Yes, the battery will slowly degrade. But, at least you have protection from a sudden crash if you accidentally the power plug :(. If you can afford it, run two batteries - swapping once every week or two (or however long it takes for it to naturally drain to about 50%), with the one about to go on the shelf being deliberately drained to about 80% first.

OT: Cordless Phone for Sale
Hi All, I have a cordless phone system that I am no longer using and thought I'd offer it for sale here before posting it on Ebay. It has a base unit with built-in answering machine and 3 handsets. Here is a link to what I have. http://www.amazon.com/AT-SL82318-Cordless-Silver-Handsets/dp/B0012CP1VS Everything works great with this phone. All handsets work and are in good shape. The base unit answering machine works perfect. The only thing that needs to be eventually fixed is that the batteries on 2 of the handsets need to be replaced. Replacement batteries can be found on the Internet (or Ebay) for $4 per handset. An enterprising PLUG engineer could even make his own as they are simply 2 AAA batteries soldered together with a pigtail connector. Please contact me off list if interested. Asking $20. Or any reasonable offer.

Re: laptop battery cycling
I run 2 laptops all day - about 14 hours a day. I pulled both batteries. They are in my desk drawer where they have been for 4+ months. Your saying it is better to just leave the battery in the laptop at 100% than to remove it? I wonder what they life expectancy is? What would be your guess? I never take the these two laptops off A/C. I when to laptops last year in the hope of less heat. And I buy cheap laptops. Both were on sale. Cheaper than a desktop.
