Urgent question very Strange problem with an external HD on mac PRO

Hi,
I have a problem with a external HD on my mac pro.
After many month of regular use with out any problem today when I turned on the HD I could not see it in the finder anymore.
I use this HD for backup of an other external HD and to do the back up I use an application called SYN SYNC
The strange things are:
1) If I start Sync Sync everything works properly as if the sofware recognize with out problem that the HD is effectively there.
2) If I open DISK UTILITY I can see the HD and if I try to repair it the utility after 2 minutes says that everything is ok.
3) If I look for the mac pro (to which the external HD incriminated is connected) on a different mac in my studio over the net I can see the external HD and I can browse the folder, copy items from the esternal HD to the MAC and even copy thing on the external HD.
I tried to connect directly via Fire wire 800 the HD on a different MAC and I could not see it like on the mac pro.
Does enyone have an idea of what's going on?
best regards
Lorenzo

I can still see all the others external Hd with out any problem and I already try this but no results I can't see that HD on the desktop and neither in the sidebar.
As I said the strange thing is that the external HD shows the same behaviour when is connected to a different MAC.
Seams the problem is with the HD not with the MAC.
I even try to use a different case for the HD using also USB connection instead of FW, but nothing change!

I have very strange problem with Iphone 3gs. Whenever it gets little hot or exposed to 30 degree temperature it losses signals (No service). Whenever it is cooled down the service is back. Please help!

I have very strange problem with iphone 3gs. Whenever it gets little hot or exposed to 30 degree or above temperature it losses signals (No service). Whenever it is cooled down the service is back. Whenever I am using Skype or playing game for a while it losses carrier signals and wifi. When it is cooled down afer shutting down the carrier signals and wifi are back. It is for sure problem is with heating, but 30 degree tempeature in Oman is normal and some time it goes upto 50 degrees. I have noticed this has started after I started using substandard charger as I lost my original charger of the phone. Please help!! Thanx.

The specifications define an operating range up to 35 degrees.

Hello,having a problem with Logic 9 on a Mac Pro.Working on a lenghty song and apparently session got corrupted.Doesnt let me export tracks,program crashes.Already tried start brand new session with the tracks imported into it but still wont export.Suggestions?

Thanks, Ian. Yeah, that's how I do it now...or with the controls in the left side pane. Still, I would have liked that quick on-the-spot edit capability...especially while sketching.

Sorry Mark, you are out of luck as it does not do that - it works the same as L8. The way I would achieve that with more accuracy and control would be to route all the tracks you want to fade to a Bus then use volume automation on the bus. To do this you will need to add a standard audio track, then re-assign it using (Control Click on the track header) to the Bus track. You can then automate volume/plugins etc on the Bus track.

10.4.10 update and very strange problem with Mac Mini

Dear All,
I have just updated my Mac Mini Intel and I am having a strange problem.
My Mac Mini has problems booting up. Sometimes I get through the login screen as normal but my wallpaper shows and there are no desktop icons, no dock, no top of screen finder menu bar. Some other times I get stuck in the progress bar of the booting up.
I tried to run utilities from install disk and there were no problems detected.
The VERY STRANGE thing is that several times now as I put my fingertip onto the power button laying it on the button but not pressing it yet (because I would like to shut down the system), the system kicks in and becomes unfrozen!!!
Someone in the 123macmini.com forum says that this problem is related to the airport receiver which is near the power button.
What do you think about it???
MacBook and MacMini Mac OS X (10.4.10)

ok, I have found a kind of fix for the problem, although may run a hardware test to check something!.
I unplugged all USB and Firewire devices, I turned off Bluetooth and Airport, reinstalled the 10.4.10 combo update, when it restarted the starting mac osx screen took barely a second or 2 to load (my comment above is becuase from when I first got it on Sunday I noticed it was slow to boot up, also noticed that the screen resoulution I have set does not kick in until I log on, although this may be becuase this mac mini is an intel one). The computer booted up very quickly and I tuend on bluetooth and airport with no issues and plugged all the usb and fireware devices back in. I again turned the airport off and restarted and again it booted up very quickly logged on and swithced the airport back on. I decided to reboot with the sirport on and it got stuck at the end of the os x starting up screen, I waited a few mins switched it off and on again and it booted up fine although slower. I dont mind turning the airport off when I power down as the mac usually stays on anyway. I assume Apple will release a fix for this as a lot of people seem to have the problem so think I will stay put with this for the time being. It was taking a several goes to get to the login screen before but usually got there every few boots.

Strange problem with changing external links site-wide

Hi, i'm having a problem that i just cant work out; i'll describe whats happening and would greatly apriciate any help anyone can give.
when i type in an external/absolute link in dreamweaver sidewide change link function i keep getting a message saying it cant find any links with that name ("no links to.....found".
i've tried creating a simple link in my index.html like http://google.com then searching for that so i know its there and dreamweaver still tells me that http://google.com, www.google.com, /google.com and every other variation i can think of doesnt exist. In addition to that when i search for broken links and click external links to try changing them there, the search function finds the links i'm looking for and lets me type in the new link i want but when i hit enter it reverts to the old link.
at first i thought it was a problem with my copy of dreamweaver but i downloaded my site to a hard drive and tried on my uni computers copy of dw cs3 and cs4 with the same outcome.
i have about 1000 of the particular link in my site that i need to change and really dont want to do this manually, if anyone could help i'd be extremely grateful.
thanks, Andy

note: although it seems straight forward i also followed youtube guides on defining my site and changing the links to make sure i hadnt missed something obvious.
although it still maybe something obvious i just cant see it and i've been googling to find out if other people have had this problem but couldnt find anything

Please Help - Very strange problem with internal String encoding

I created a file in one-byte russian encoding cp1251 and declared String literal with 2 letters:
String str = "ab"; //attention! ab - two russian characters
After I got bytes from it - str.getBytes("cp1251") - it returned 2 byte's array.
Now I created a file with UTF-8 encoding with equal content and suddenly:
After I got bytes from it - str.getBytes("cp1251") - it returned 4! byte's array. Why?
I need to get a one-byte encoded arrays (cp1251 or koi8-r) but getBytes ALWAYS returns two-byte encoded arrays.
It is very strange: cp1251 is always one-byte encoded, but .getBytes("cp1251") returns two-byte on each letter. Why? Please help.

I did not read a string from a file. I created 2 .java files with different encodings (cp1251 and UTF-8) and compiled them, telling compiler with -Dfile.encoding=*** to read them correctly. While execution java interprets two looking equal in editor strings as different objects with different .intern() representation.
Why java consider source .java file encoding while creating internal representation of String object and creates from looking equally in editor strings two DIFFERENT Unicode representations. And it is impossible to convert one representation to other - impossible to get two equal byte[] arrays.

Strange problem with a 2 hard drive mac

I have a power mac 7600/132 used for os9 apps that has had 2 hard drives for the longest time. One day the second hard drive wasn't showing up but the original hd works fine. I found that if you disconnect the power cord from the original hd and leave the scsi? (the bigger plug) plugged in the second hard drive will work fine but if i disconnect the scsi plug from the original hd leaving only the second hd hooked up by itself nothing works at all. I think this is very strange but is there a fix for this i am looking to use the second hard drive only if i can get it to work alone.
to clarify this:
when both hard drives are hooked up properly: only the original hd works the second drive i can hear spinning up but does not appear on desktop.
when i disconnect power cord from original hard drive but leave its scsi cord attached and have second hard drive hooked up properly: Second hard drive works fine.
when i disconnect both cables from the original hard drive completely from the system and have second hard drive hooked up correctly: nothing works, mac wont even boot from cd.
i cant make sense of this but maybe someone else will know
thanks for any help you can give me

It would be really nice if every manufacturer arranged their jumpers the same way. But alas, that is not the case. Some manufacturers have a general trend they tend to follow, others have a different arrangement for every drive they sell.
Drive Jumpers are tiny plastic cases that conceal a stamped brassy-looking shunt. This is placed over two adjacent brassy-looking pins to make a connection. The jumper used for Termination is just like the ones used for SCSI addresses. There may be one two or even three different places on the drive where these jumpers appear, and they sometimes even use different sized jumpers at the different locations.
There are two spacings for drive jumpers. Older drives and most IDE drives tend to have their pins spaced 0.1 inch apart, so a stack of 10 jumpers side-by-side would be an inch tall. Many SCSI drives use jumper pins that are 2mm spacing, so a stack of 12+1/2 would be an inch tall. It seems like not a lot of difference, but the moment you have to install two side-by-side, you realize that sometimes you need exactly the right size.
If you can post the make & model of the drive, (and the capacity if you have it) someone will either have a printout of the strapping guide or be able to find one online.

Problems with Digitus DA-70577 on MAC PRO 4.1

Hello
My USB3 Digitus DA-70577 connected to my MAC PRO 4.1 through the Cal digit Card stops working randomly and requires to be switched off and on to work again.
The apps with files linked to the drive freeze and occasionally I must reboot the Mac
I think it's not a Cal digit problem as in the second port I have a USB3 RAID system working well at all times. I also tried to change the RAID and the HDD in the two available ports but nothing changed
I use this set up while editing so is really annoying and I also worry to eventually break the Drive inside the enclosure
Any suggestions if this happened to anyone
Regards and Thanks

@Pete_B100, thank you for a different direction. I was able to start an install with the drive in an external USB bay. However, I could not get it to boot ML inside the internal bays. This got me thinking...
SOLUTION: This was an error on my part. I bought my MacPro 4,1 without the WiFi card in it. Around the time I bought it, I had a Mac Mini that I was using for parts. I took the WiFi card (Model No. AR5BXB6) out of the Mac Mini and put it in the Mac Pro. Worked like a champ for SL and Lion. While I was in there yanking out drives, I decided to yank that out. The hint was that the ML USB boot could not see my WiFi card. After I took it out, it was operating like it should. I was able to do a Clean Install of Mountain Lion on my Crucial M4 SSD with no problems.
Thank you all for your help and suggestions!

Major problems with Server 10.5 on Mac Pro

My Mac Pro was running Leopard 10.5.6.
I installed 10.5 Server on a separate internal hard disk. It installed OK, but when I successfully logged in and downloaded the 10.5.6 v1.1 update, the computer froze on Log Out. I had to power it off using the power button.
When I started up again, after I type in my login credentials, only "Server Assistant" opens. No dock. Just the "Server Assistant" menu bar. And I can't do anything except move the mouse and see the menu. When I press Command-Q, it closes Server Assistant and logs me out.
This happened to me twice; on two separate installations.
Any help would be appreciated.

Well, the obvious question is what processes are running on the machine that could be consuming bandwidth.
There are three scenarios I can think of that might cause this.
One is the server trying to download a large amount of data - e.g. if you startup the Software Update Server it will download gigabytes of software updates from Apple. I'm guessing this isn't the case if it's been going on a long time.
Option 2 is a misconfigured service that's allowing your machine to act as an open relay (e.g. a web proxy or mail server) and other users are bouncing traffic through your machine. This is absolutely something you should fix.
Option 3 is a hacked/compromised machine that's doing something it shouldn't.
Of these option I think #2 is the most likely. If you're running an open mail proxy you will get hit by spammers using your server to spew their wares.
You should look at the server logs to see what's going on. Specifically /var/log/mail.log for the mail server and /var/log/httpd/access_log or /var/log/apache2/access_log for the web server. If either of these are large and growing you may have a problem.
Once you identify the source of the problem you can implement a fix, but until you know which service it's impossible to be specific.

Power problems with Radeon 3870 on 2008 Mac Pro

I've got a 2008 Mac Pro (10.5.7) and I've replaced the 2600 card that came in it with two Radeon HD 3870s and I am having an issue.
The cards are in slots 1&2 (the higher speed slots.) After a short period of time, the card in slot 1 powers off its monitors, but the monitors on the second card remain active. Only a reboot reactivates the monitors on the first card.
In the process of debugging this I've removed all cards and put 1 3870 in slot 1. The problem remained.
I swapped in the other card in slot 1. The problem remained.
I then tried each card in slot 2. The problem remained.
I've reinstalled the 10.5.7 updater, but this didn't help either.

Very strange problem with sound in dvd player

Hi
I have a strange issue which I am cannot resolve. I recently purchased season 2 of NYPD Blue on dvd, region 1 (http://www.amazon.com/gp/product/B00008YGRR/qid=1151702794/sr=1-3/ref=sr13/103-1409159-4182204?s=dvd&v=glance&n=130). The season is spread over several discs. The region of the dvds is the same as that of the superdrive on my 1.25 factory spec 15” pb running 10.4.6.(always has been region1) On playing the dvds in dvd player, the sound is very quiet, and you can hear a slight hissing noise (picture is fine). However, if I set the balance of the speakers in system preferences to the left (as far as I can) the sound becomes louder and the hissing disappears. Hence the sound is normal, other that the fact that it is unbalanced. The same happens if I set the balance to the right. Hence the hiss is only there when the balance is set to the centre or around it i.e. slightly to the left or right. This problem is true of all the dvds in the set.
Fair enough, the nypd discs are defective.
However, I then played them in a standalone dvd player without any fancy sound settings etc and no problems at all. Hence I then thought that the problem was with my pb - the only different thing I have done lately is use handbrake to put some of my other dvds (not these NYPD ones) on my iPod, so I thought that handbrake had done something (although I don’t know see how it could have done anything). However, today I tried some other commercial dvds in my pb (produced by the same company) and they sounded fine as has been the case for over two years. Hence, there is something about the nypd blue dvds which affects the quality of the sound output in my pb when the balance is centred. However, whatever this is it doesn’t seem to bother standalone players, nor is it something that anoth of my other dvds have.
Any ideas on what exactly is going on here, as it has me stumped.
(I don't have any other season of nypd blue, so I can't see if these have the same problem as well.)
Thanks

Sorry for replying late.. Was very busy.. So, the thing is that I disabled every module & loaded only microcode & powernow-k8 in /etc/rc.local. Now, I'm getting good speed while copying data but the problem is that the processor is running & full speed i.e. 3.0 GHz. I checked it via cat /proc/cpuinfo. Also, there is a message in the bootime, that i'm posting here..

Very, very strange problem with iPod Touch. Won't play in my car.

I'd understand if I just plugged my iPod Touch into my car and it didn't work. That could mean it's simply not compatiable with my head unit, it could mean the head unit isn't up to date enough for it. However, the first couple of times I plugged my iPod in, it worked perfectly. It charged the iPod, loaded playlists and played the songs without any problems. But suddenly, it has stopped charging and playing songs. It won't even load the iPod anymore. On the head unit it just says it's searching for the iPod, but it never finds it. On the iPod it says it can't be charged on this device.
I have an Alpine head unit and a 3rd generation 64GB iPod Touch. I really don't understand why it would start saying it can't be charged on the device, when I've charged and played songs on it before. I already know it can work on the head unit.

Unless I'm missing something Chris, I would think it very important if the Touch was charging from the very beginning. Of course if the Touch was fully charged when you first tried it then the songs would play.
Are you saying that your Touch appears to be playing tracks fine and has a charged battery, it's just that the sound isn't being played through the Alpine? Does it connect via the headphone socket of the Touch? If so, then plug some earphones in to see if any sound is coming out. If it is then it's either the cable connection to the Alpine (assuming it isn't Bluetooth as I'm not familiar with you Alpine or the Touch version you have) or the Alpine head unit itself.
You can very easily determine if the Touch is working and thereby eliminate that as being the problem.
Finally, I'm surprised you don't appear to think that it's important your Touch is being charged as obviously if it's not then after a while it will stop!

Very strange problem with wikipedia on my Macbook Pro 15"

I have a Macbook Pro that I bought in June 2010, 2.66 GHz Intel Core i7 4 GB memory, Snow Leopard OSX (of which all may not be relevent) but recently I've been having possibly the WEIRDEST issue with wikipedia. I just go to the site, and a split second after it loads the main page, part of it becomes blue almost like it's highlighted. You may think this is just me being stupid and highlighting text but believe me I've tried to deselect and it isn't any use...I don't even think it's highlighting the page at all. Frankly, I don't even know what it is. here's a screenshot:
http://s1165.photobucket.com/albums/q597/wmblair/?action=view&current=Screenshot 2012-04-16at44957PM.png
I highlighted part of the body of the article to show that it's something weird with wikipedia and not just me selecting something...I mean, at least one other person must've had this problem at some point, RIGHT? It really looks like I'm highlighting it but it isn't possible to highlight those two specific parts of the article at the same time. Hopefully I don't sound crazy, but this has been a puzzling mystery for me for weeks now.
Anyone have any ideas/suggestions on what could've happened? Obviously it didn't use to be like this.
Thanks,
Will

I cannot find a way to select two different chucks of text in safari, chrome, opera or omniweb. In firefox however, I can use the command key to select additional text. So that implies its a function of the browser implementation.

Very strange problem with Ethernet

(All this started to happen after Maverick update)
On fresh start everything work OK, Ethernet and Wireless. I usually work only on Ethernet, with Wirelles turned off. But after some time, my Mac just turn Wirelles on by itself, and disable Ethernet connection. What is most strange, after that point I cannot open System Preferences. Start to open (jumping icon few times) and nothing happen, no window, nothing. Only thing I can do is to Force Quit System Preferences. And only after that I can restart Mac.
Of course, after restarting everything is back to normal, i can open System Preferences, Ethernet is working etc. Didn't figure out yet after which time ethernet stop to work.
Please help!

So it works with AirPort but not over Ethernet?
Have you tried creating a new location in System Preferences Network pane, and setting Ethernet up from the default settings?
Make sure the iMac G5 is not set up to do +Internet Sharing+ (using the Ethernet port); look in System Preferences Sharing pane, and turn OFF +Internet Sharing+ if it is currently ON.
Is one of the other workstations a Mac? If so, you could use it to test the iMac G5's Ethernet port, by connecting it directly and using +File Sharing+ (I suppose you could do that even with a Windows PC).
