Cdrecord -scanbus doesn't find burner--udev issue?

Hi there,
I just tried to burn my weekly backup, but xcdroast was complaining it couldn't find any devices. So I tried the different scanbus options as root:

I'm running the stock Arch 2.6.10 kernel.
Now, burning worked just fine last week. Since then, I updated udev, and I had quite a few issues getting my optical drives to work properly again (DVD couldn't be read and whatnot). But I'm at a loss where I should start looking for a solution for this problem. Any hints or ideas what's wrong now?

Na, no offence taken. It's typical for me to search for a solution to a problem for hours, finally posting a question on the boards just to stumble over a very easy solution (e.g. re-installing the cd burning tools) minutes later. It always makes me feel stupid.
I'm very happy with Arch's udev implementation indeed. Had hardly any problems switching from devfs, and the wiki helped lots with permissions and whatnot.
Question, though--as suid doesn't seem to work for cdrecord any longer, how can users burn CDROM with nautilus-cdwriter? It's not a real problem with xcdroast (thanks to its wrapper, if that doesn't work just start it with sudo), but how to get it working for nautilus?

I have an issue with time machine, it doesn't find the Lacie external driver it use to use. it is the same drive that I usaly use for time machine back ups. It is corectly plugged. What can I do ?

Hi,
I'm trying to back up my macbook with time machine on the Lacie external driver I usualy use for this, but today my computer doesn't find the driver. I haven't done back up in 6 month.
Today, the Lacie driver is pluged and running, but the computer just does'nt find it.
what shall I do ?

Some things to consider:
Is the drive mounted, i.e., visible via Finder and/or on the Desktop?
Is the drive still selected in System Preferences, Time Machine? If not, use the "Select Disk" button.
Is Time Machine still turned on (System Preferences, Time Machine)?
Can you see the drive (and mount it) using Disk Utility (in your Utilities folder)?

DVD Drive & Burner App Issues

Hey guys, I've searched the forums for several days on this but can't see to find the fix.
I've been running Arch for about 2.5 years, upgrading daily, and all was going well, but yesterday I decided to do a fresh Arch install. The new install went fine and I'm using it now, but I'm having some troubles with my DVD drive and any CD/DVD burner apps that I try to use. Those same apps worked perfectly in my old install.
K3b now launches very slowly on the first start but it does detect both, my dvdr, and cdrw drives. However, on a K3b restart during the same Linux session, it only sees the cdrw drive. If I reboot and restart K3b, the process is repeated.
Graveman just hangs on trying to detect my drives on the first start, and it has to be killed manually. It never gets past detecting the first drive.
cdrecord gives this:
$ cdrecord -scanbus
scsibus1:
1,0,0 100) 'PLEXTOR ' 'DVDR PX-740A ' '1.01' Removable CD-ROM

/dev/sda7 swap swap defaults 0 0
/dev/sda8 /home ext3 defaults 0 1
I didn't have any modules in rc.conf before the new install and all worked well, so I didn't put any there this time either. I've tried reinstalling K3b, Graveman, and the kernel, but none of that helped.
It seems to me that this all has something to do with the new drive naming scheme, but I'm not sure.
Anyone have any clues on a fix for this one?
Thanks in advance.
oz

Hi, T-Dawg
Yep, graveman still hangs, so it might not really be K3b's fault, but a possible kernel problem instead. However, the current kernel works fine with the previous version of KDE. In the bug report mentioned above, someone claimed this issue will be fixed with the 2.6.22 kernel, so I guess we'll know soon enough.
Command line burns work perfectly so I'll keep using that and skip on hard coding the device to sr0 for now. Might do that if the new kernel doesn't work, though.
Thanks for your help.
oz
Edit: I've tried k3b 1.0.3-1 that just came out earlier today, but it has the same problem. Gotta go all the way back to version 1.0.1 to get things working again.

My ipad doesn't find my printer....

How do I make my hp 3510 discoverable to my ipad? The wireless printing works from my laptop which has the same wifi settings, but the ipad cannot find the printer????

Hi Kiwisteve77,
I understand the Ipad doesn't find the printer.
Thank you for your reply.
I will be happy to help you with this.
Try turning the wi-fi off and on again on the Ipad.
If that doesn't work turn the Ipad off and on again.
Check to make sure it is connected to the proper network.
Power cycle the router, Ipad and the printer and try it again if you are still having issues.
I have provided a document for How to Use Apple's AirPrint Over a Wireless Network. Go to the section What if a 'No AirPrint Printers Found' message displays on my Apple device?
Hope this helps.
Thank you for posting on the HP Forums. Have a great day!

ITunes Diagnostic Doesn't Find Audio CD or iPhone/iPad - Help!

I
I’m having issues with iTune to recognize my iPhone and iPad. My iPod nano (G5) is recognized. I’ve run diagnostics with two failures (No Audio CD Found, and No iPod, iPhone, iPad connected). A month ago everything was working. What happened? I’ve spend many hours following the instructions that’s on the web without success. BTW – the music list that’s on my ‘test’ CD is displayed in iTunes and can be played. It’s very strange that the diagnostic shows a CD/DVD issue. I don’t have a virtual drive. 'Importing the CD' works cleanly - no problems.
I am at a loss. Any suggestions, phones numbers?
Thanks, Pat

Walkman app doesn't find many files below a letter

Hi everyone, I've got this problem with the Walkman app: it doesn't find anything under the 'G' so if I search for a song/album/artist beginning with 'G' it founds it, if it begins with 'I' Walkman doesn't find anything. I tried with Play Music by Google and everything works there.
I hoped to see the issue fixed with the update but it didn't do any good.
Help please?

You can uninstall updates but it is not sure your issue is fixed.I tried on my device,I searched with one letter,I did not get anything.But after I inserted the second letter,it found songs.
All we have to decide is what to do with the time that is given to us - J.R.R. Tolkien

Digital Editions doesn't find books on ereader - possibly because Kobo used w/ different Adobe ID

I used my ereader for the first time on a friend's computer. I was just loading a pdf quickly.
Now, even though I have authorized my computer to my own adobe ID, digital editions doesn't find books I purchase from the Kobo online store. This means I can't move them from my ereader to the digital editions program.
How do I get digital editions to find those books? I have never downloaded those books onto any device but my kobo.
Thanks for any advice.

Can I add to this?
SONY has begun to tighten their controls over their ereaders. The first
step was to change the way their Reader Store works, so that it becomes
more difficult to download content to their ereaders from other sources.
Your husband may experience some issues in the near future when he goes to
use ADE to download to his ereader because of this. Technically, when a
SONY ereader is registered with SONY, the process includes downloading a
Reader Library to your PC. When you plug in a SONY ereader, it looks for
this Library and synchronizes with its contents. SONY can interact with
the library via the Internet, and can change what's there, which then gets
transferred to the PRS.
If bad comes to worse, and your husband's PRS starts to act up when
attached to ADE, there are options to get around this issue. C'mon back if
that happens!

MacBook doesn't find Wifi and mouse behaves weird...

When the new iOS came out I received an update message also for my MacBook Pro. Since I installed the update the system doesn't find any Wifi connection any more! Even not when I try to choose a connection in the system settings: There is no single connection listed in the network list and the Wifi-sign keeps blank without any signal sign.
Since the same time also my mouse refused to work properly: Scrolling is now impossible and when the Magic-Mouse is switched on, the active window starts to move up and down.
Don't know exactly if this strange behavior came from the iOS (iTunes, whatever) update or from another one: At the same time I downloaded also a Firefox and a Skype Update.
Does anyone observe similar problems since the last iOS update release?

I'm having the same problems recently. Bought my white MacBook in Jan. '09, worked great for several months; now it won't stay on the Internet for more than five minutes at a time unless I'm right next to the router. The Airport icon, when selected, shows my network but for some reason it has been deselected. My husband's Dell has no problem at all, even if he's out on the back porch, so it's not a signal issue.
I've updated the software to the latest Airport but that seems to have made it worse. I've tried nearly all the things Solvi did to no avail. Has there been an answer yet from Apple on this?
(Had to re-select network to sent this short post!!)

Mac doesn't find Apple TV but iPad does..

Hi
I bought a Asus rt-n56u the other day and set it up with my Netgear cg3700 provided to be by my internet supplier. I turned off the router mode on the cg3700 when I connected them both.
When I tried to airplay a video from iTunes on my mac (macbook pro mid 2010) it doesn't find the Apple TV. Homesharing from the Apple TV doesn't work either (although it did before I installed the rt-n56u). I can't airplay or share my screen from a 2013 macbook air either.
But when I try to airplay videos from my iPad it works just fine. Furthermore I can access my videos in iTunes on my iPad trough homesharing.
This means that they are all on the same network and I can play a video in my iTunes-library on my Apple TV by finding it trough homesharing on my iPad and then airplay it from the iPad to my Apple TV. But I would like it to work as it should and not this way.
Does someone know what I should do to get it to work?
(I've tried to restart the modem, router, Apple TV, Mac and so on ...)

Apple unwisely used the name Airplay mirroring in my view as older Macs could only push a pre-rendered iTunes stream (eg purchase) via Airplay.
Airplay mirroring is quite different as you may know which is why older Macs are not supported.
This really does sound like a networking configuration issue - you've done the restart all devices I'd normally suggest.
Are some devices on ethernet?

When I launch I photo it wants me to choose a library but it doesn't find one which is impossible, because i still have no storage. before i can clean up i want to back up them. how can i find my library?

You may very well have damaged your library - or even your system by not having adaquate storage available
And never select all of the pitcture and move them - that will destroy your library - the iPhotolibrary is a SQLite database and must always be kept intact as a single entity -
Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

ICal search doesn't find anything

when I test this by creating a future event with a particular word in it, then return to today and search for that word in the little "search" box at top right, it doesn't find that word.
Why not?

I have also had long standing problems of not being able to search for calendar events, either from within iCal or Spotlight or using mdfind.
None of the suggested solutions worked for me (removing Calendar Cache file, adding and removing folders or drives to the privacy section of Spotlight to re-index, or running mdimport ~/Library/Calendars.
One clue was that mdimport -d2 ~/Library/Calendars would not even look at the individual .ics files within any .calendar/Events directory (no output). I suspected that this was due to LaunchServices not associating these files properly with iCal. My system had previously been upgraded all the way from 10.0 through 10.6.
What finally worked for me was the following, using the Terminal, rebuilding completely the LaunchServices database:
rm /Library/Caches/com.apple.LaunchServices*.csstore
*defaults delete com.apple.LaunchServices*
*sudo /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServi ces.framework/Support/lsregister -kill*
*sudo /System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServi ces.framework/Support/lsregister -R -domain local -domain system -domain user*
(note the capital -R in the previous line.)
This step will take a few minutes to complete, with a message about I/O throttleing
reboot (not sure if that is necessary)
*mdimport -d2 ~/Library/Calendars*
This last command should now show the successful indexing of all calendar events.
After this search finally worked again for me!

Heiko

Search engine doesn't find vcards

The search engine in Address book doesn't find cards that exist in my ALL. They were cards imported via Time Machine. Any way I can get AB to index it's content ?

One week later, I'm still hoping (praying ?) for a solution...

Find palette doesn't find the IPCT category field

I have all my pictures by categories and suplemental categories. The "find" tool doesn't find anything if for example I type ARC (architecture), no matter if I select containing, containing all, starting or all metadata, all, etc... It seems that it doesn't search in some IPCT fields, at least in the category and suplemental category.

You are right. "find" will find IPTC entries in caption, say, but not in category. I guess it's like EXIF, where it's only make, model, serial number, artist, and software.

The "Search" function box doesn't find things that are there! Why?!

The "Search" function box doesn't find things that are there! Why? Eg: It doesnt show all my Sent and Received emails, but it will find an email that I half wrote and deleted. Unsure why or how to explain more fully.
I also don't understand if I type in "James email" or "J" into the search box and all the J / James stuff appears but it doesn't show the emails I know have been sent and I know are somewhere because I rang "James" up to check, but the search box shows random thing I am NOT looking for, even if I type in fully what I am looking for and test it by typing in full titles of things.
It also doesn't store all my sent emails in "Sent" box. Confused! I'm not sure if the "Search" box just isn't up to the job or if it is broken / i'm doing something wrong? Maybe the email address I use isn't set up properly?

This can happen sometimes if the cache is not cleared correctly when items are not deleted from your device.
The only solution to this is to do a restore to clean out the cache file.
