  • Is there a compatibility problem with OS 10.3.9 and some 1TB external HDs?

    Hi,
    I just got a Toshiba external 1 TB HD. It wouldn't mount on my G5 PowerMac running 10.3.9 ( I get the error message to ignore or initialize, but Disk Utility can't mount won't mount it to do so.) So I tried it on my MacBook Pro running 10.6.8. It showed up there and I initialized it and partitioned it using Disk Utility. I am hoping to use it to run Time Machine on my laptop and manually back up files on the partitioned volume for the tower but it still won't mount.
    Is there a problem with the size of the HD and either the PowerMac or its OS? Is the partition a problem?
    Thanks for any advice.

    Hi a Brody,
    thanks for helping me with this.
    I do not need to boot from the 1TB drive, only for storage. When I try to initialize/partition it using disk utility (10.3.9) it hangs up making the partition map. Also, it only recognizes 931GB of the disc. When I first initialized it using 10.6.8 it showed much closer to 1TB.
    Not sure how to initialize or partition when disc utility gets hung up while doing so.

    my iphone 5's screen blacks out every now and then. the phone is turned on but the screen is black and i can receive calls. what is wrong with my phone?

    I have to believe this has something to do with iOS 7 issues. I have taken my screen blacked out 5s twice to the Genius Bar and the found a bunch of system apps had crashed.  So if this is the case, is iOS7 the problem?

  • TS3276 I have recently had a problem with one of my hotmail accounts, some sort of virus sending random emails to people in my address book. Hotmail advised me to change my password for that account, which I did. Why won't mail recognise the new password?

    I have recently had a problem with one of my hotmail accounts, some sort of virus sending random emails from my address book. Hotmail advised me to delete all contacts and change the password for that account, which I did on my laptop running windows XP. The change was successful and I was able to send and receive emails with no problem. I then had to change the account password on my iPhone 4s, which I did and it too was successful but when I came to change the password on my iMac, running the latest version of Lion it would not recognise the new password. I have tried to remove the account details and re-install but every time I go to add new account my old details are in the box. This is very frustrating as I use my iMac for all my profects and I need to access my email. Please help.

    hi guys,
    I had already deleted all reference to the hotmail account in question from the keychain access app, I have also tried to delete and re-instal the account details from within mail. The icon in the side bar dissapears but when I go to Add Account, the old account details are in the new account box. I then input my new password but am told that the server does not recognise it. If I access hotmail via google on the iMac I can get into my account with no problems. I am thinking there must be some other form of security system within the mac software that is blocking the new password. This is driving me nuts. I have been trying to resolve this for the last two days. Thank you for your advise anyway.

    Some progess I see. To be honest, i would not waste your time with trying to connect using wireless.
    You are likely to get poor connections and dropping out.
    If its working using a cable, then there is no need to bother with giving me the network settings, bu see how it goes, because sometimes giving the TV a static IP address can give better results.
    There is an example of a couple of powerline adapters on the diagram below. Just ignore the network switch unless you want to connect other devices which are near to the TV.

  • My host name changes every few days, since Xmas adding a macbook its changed 6 times. Do I need to stop this? Does it cause problems with sharing between the iMac and macbook?

    my host name changes every few days, since Xmas adding a macbook its changed 6 times. Do I need to stop this? Does it cause problems with sharing between the iMac and macbook?

    There are several possible causes for this problem.
    1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local".
    2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
    3. A Mac wakes from sleep due to network traffic. This is due to a bug in OS X that may only affect some models.
    4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
    5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.
    6. See also this support article.

  • Problems with my laptop starting - Satellite P745, Windows 7

    For the past few months I've been having a very strange problem with my laptop. I have a Satellite P745-S4380 with Windows 7. There are times that I can shut it down and turn it on with no problems. However, a majority of the time when I shut my computer down, it will not turn back on. When I push the power button, the following happens:
    the power button lights up
    the fan starts running
    I never see the "Toshiba" screen and my computer does not start
    The only way I've gotten my computer to turn back on is to either:
    1) unplug my power and let my computer run in this "fan running, power light on" mode until the battery dies - then generally when I plug it back in, it will start right up
    or
    2) wait 5 to 7 days, then it will start right up
    I don't use it on a daily (or even weekly) basis because I am on the computer all day at work, but I would have to guess this started around June. I'm trying to determine if this is something like a motherboard failure, or if it's some sort of software/hardware update that is not setting well with my machine. Has anyone else had this issue? Any ideas on things to even try troubleshooting? I think it may be related to an update or setting (maybe because I don't want it to be the motherboard) because even if I go to reboot it at times, it will shut down but will not come up and it will get hung in the same state as I described above. If my motherboard is bad, would it act like this? I'm at a loss with where to even start...
    Something else to mention is that if I put it in "hibernate" mode, I haven't seen this issue.

    Hi ! There are many discussions about whether you should shut your PC down or just leave it run. I never allow my PC to go into sleep or hibernate mode. I allow my monitor to shut down after 15 minutes of no activity. I turn my wireless mouse off when I'm done with my PC. When I return to my PC, I turn my mouse on and my PC starts up immediately. That is the way I use my lap top. It's a choice for you to make. I have no proof it it is good or bad practice. Of course this would need to be changed if your operating only on battery.

  • Serious problem with blackberry 9300 Curve handset and denial from BB to replace the same, under warranty.

    Dear Blackberry Authorities,
    It is really a horrible experience with the handset of blackberry for me. I have purchased blackberry Curve handset 9300 on 22nd April from a "Phone Store”, Shop No.78,79,community centre, New friends colony, New Delhi, The Invoice No. is 319,The details of the handset are as follows:
    Handset: Blackberry Curve 9300 1256-India Qwerty-Pink
    Name: Blackberry 9300: ETA-716/2010/WRLO
    Model: RDA71UW
    It has been more than just three months ,when i purchased this handset ,It worked fine for about only fifty days from the date of purchase and from the second month ,to my shock, serious problem started in the handset and some time it was getting hanged ,sometime some keys in the keypad did not work ,some time it was getting hanged the moment I receive incoming call., sometime sms sending problem, some time some other problem ..Every time I used to switch off the phone and start again, then it used to work but after some days again there were some other problem occurring in the handset.
    The phone was not getting connected to PC from the starting, and i have tried so many times but i fail to get success.
    Many a times when I used t send sms the entire alphabet typed on sms has gone separately as a single alphabet in a particular sms to the recipient, causing embarrassment for me in my organization. I would blame the black berry for this embarrassment as this has caused due to faulty phone they have sold me,
    I am service class person and i get occupied with my work at office in the day hours and doesn’t have time to go to the service centre of blackberry every time the problem occurs, as there are only one service centre available in Delhi at Lajpat Nagar.The service centre is about 20 Kilometers away from the area my office is situated, I managed to keep the phone running by switching off and switching on after one or two minutes, every time the problem occurs but in the first week of last month ,when the problem started continuing  after  switching off and switching on also ,I was bound to go to service centre at noida since it is close to my place (about 14 Km) in comparison of Lajpat nagar at new delhi,the service engineer at blackberry service centre saw my phone and said there is some software problem which can be rectified by reinstalling the software, and there are some hardware problem also (some keys on the keypad is not et. all working) ,for which i have to surrender my phone to them and they will send it to the Blackberry Office (they did not give address) and it would take 15 days  at least ,thus since I had no back up phone and my each and every contact no. was there in phone it was difficult for me to give them handset at that time ,so I requested them to rectify the software problem by re installing the same.
    I asked the service manager to get the backup of all the data and contact no saved into the phone, but they refused to do so and they asked me to go to some other shop nearby to get the data backup, I went to that shop and they asked 250 Rupees for data backup of my phone. I was bound to say yes to them for the amount the charge for backup .I gave them my handset and after 20-30 minutes they came back to me by saying, we cannot store your data backup as it is not connecting to PC. It was a highly disappointing reply for me.
    Then i again went to your service centre and written down some important contact no.(the number which was stored on phone book) on piece of paper  and taken out my SD card ,and gave them handset for re installing the same.
    They gave me my handset after one and half hour and said" now it would work fine except hardware problem.".I came back and to my utter shock again after two three days handset was into its old condition ,then also I tried to manage with handset and when i could spare sometime I went to your service centre again on 24th July at Noida,
    they took the phone and said it would take 12-15 days to return the handset after rectifying the problem,when i requested them to change the handset with a new handset which is at least in good working condition , they clarified that if the hardware problem is not manageable or repairable ,i would get new handset had no option except to give them handset for rectifying the problem.
    Now,It is the time for a biggest shock from blackberry people-Today on 3rd August ,i have received a call from noida blackberry service centre to inform me that my handset cannot get repaired under standard warranty conditions of blackberry as there are some moisture into the phone and there is no warranty if there is a moisture inside the phone.
    Thus now i wish to inform all the concerned ,Blackberry/Research in Motion ,managers/authorities ,that i have explained above ,all the things ,happened to me in last three months of my purchase of handset, in detail ,so i would again request to Blackberry/Research in Motion ,managers/authorities, to rectify the problem of my handset or change the entire handset so that I can use the same peacefully and should not roam around the service center of blackberry.
    Giving this lame excuse that "there is a moisture inside the handset and thus it can’t get repaired or changed under warranty " is a clear case of cheating and harassing the customer, I have bought the handset to use it for my communication purpose not to roam around the blackberry service center nor to put water or moisture inside the handset and play with the handset and fight with all of you.
    If there were some moisture inside the handset then that should have been seen by the noida service centre people also during my First visit itself by them and they would have refused taking the handset for repair. They did not refuse but accepted handset and reinstalled software also, If there was some moisture that would have been seen by them that time only.
    In my second visit also the took my phone and seen the inside condition also of handset in front of me ,they did not see any moisture, that time also ,and now after 10 odd days ,there are some moisture inside the phone??????.
    I have no idea how blackberry keeps its handset ,which has come to them for repairing ,but if there is any trace of moisture into my handset ,that would have come into the handset ,during these 10 days only when phone was with blackberry authorized service engineers for repair purpose. What I know is that My Blackberry handset is under warranty and it is not working properly thus it should be replaced by Blackberry.
    On the keypad if some key are not working that is a hardware problem which was there in the handset and it has no connection with the moisture.
    If this is the way blackberry is treating its customer, i would say it is harassing its customer, and does not want to rectify the problem .in this case, I would have no option left except to go to the consumer court in Indian judiciary system. And moreover i would inform my and other friends, organizational employee also not to use services/or buy blackberry handset if this is the way BB is treating its customer.
    I would request all the concerned persons/managers/authorities of Blackberry/Research in Motion, take action into my case urgently and rectify the core problem into my handset instead of giving lame excuses, and change the faulty handset of mine with a new properly working handset under warranty condition.
    Best Regards
    Asim

  • Help me please : Serious problems with collection-mapping, list-mapping and map-mappi

    Hi everybody;
    I have serious problems with list-mapping, collection-mapping and map-mapping.
    Acording to specifications and requirements in a system I am working on it is needed to
    get a "list" of values or an indivudual value.I am working with ORACLE 9i Database,
    ORACLE 9i AS and ORACLE 9i JDEVELOPER.
    I tried to map a master-detail relationship in an entity-bean, using list-mapping.
    And this was very useful in order to get a "list" of details, ...but, when I wanted
    to get a single value I have some problems with persistence, something about "saving a state"
    despite I just want to get the value of a single detail.
    I decided to change it to map-mapping and the problem related with a single detail
    worked successfully, but I can get access to the whole bunch of details.
    May anyone of you help me with that?
    I am very confused I do not know what to do.
    Have any of you a solution for that problem?
    Thank you very much.

    Have you tried a restore in iTunes?

  • I installed lv 6.1 on a windows 98 system. As I am having problems of stability (much more than with the former release 6.0), I would like to know if there is some specific problem with windows 98 or there is some patch.

    I installed lv 6.1 on a windows 98 system. As I am having problems of stability (frequent crashes, much more than with the former release 6.0), I would like to know if there is some specific problem with windows 98 or there is some patch available.

    My experience with Win98 is that it is not a very stable system, regardless of software used. For example, Win2000 and XP are far more stable than 98. I've had it crash on its own if I leave the computer on for several days.
    I wouldn't recommend running programs for long time (few days) on this OS.
    This being said, can you be more specific in your question. What kind of stability problems did you have, which VIs did you run (if possible post them here), did you change the interrupts and priority levels on those VI, do you get error messages or blue screen....

    Problems with creation of catalogue XPGrpwise and temporary files.

    Log Message:
    Cleanups from the spark text changes and some bug fixes for VideoElement.  Also some PARB changes for UIComponent.
    TitleBar: Changing the skin part type from Label to Textbase
    UIComponent: skipMeasure()->canSkipMeasurement() to be in line with GraphicElement.  This has been PARB approved.
    UIComponent: same with hasComplexLayoutMatrix...this replaces hasDeltaIdentityTransform.  This has been PARB approved.
    StyleProtoChain: cleanup around what interfaces to use
    TextBase: clean up code that?\226?\128?\153s no longer needed.
    VideoElement: Fixing 4 bugs:
    SDK-22824: sourceLastPlayed keeps track of what video file we?\226?\128?\153ve called play() with last.  This way if a user pauses the video and wants to start it up again at the same point, we can call play(null) on the underlying FLVPlayback videoPlayer.  However, anytime the souce changes, we want to null out sourceLastPlayed.  This was causing a bug when someone set the source to null and then reset it to it?\226?\128?\153s previous value.
    SDK-23034 (GUMBO_PRIORITY): This deals with some FLVPlayback quirks around sizing.  I had put in a fix so we weren?\226?\128?\153t setting width/height on the underlying videoPlayer too many times, but apparently we need to make sure it always gets called once.  Hopefully when switching to Strobe we can cleanup this logic...I put a FIXME in to do this.
    SDK-21947/ SDK-22533 - some video files don?\226?\128?\153t always send out a metadata event.  I?\226?\128?\153m not quite sure why this is, but in case this happens, we do a check in the ready handler to see whether we should call invalidateSize() to make sure it gets sized properly.

  • Problem with QT 7.1.5 and Sorensen codec?

    Has anyone noticed a compatibility problem with Sorensen video 3 codec and Quicktime 7.1.5? This problem did not seem to exist in prior versions (hence have been asking how to reinstall previous version but seems impossible). Some of the earlier postings discuss software that may be designed with Sorensen codec... these may be the ones not functioning properly now (video no longer works). Does this sounds plausible?
    Mac Mac OS X (10.4.8)
    Mac Mac OS X (10.4.8)
    Mac   Mac OS X (10.4.8)  

    That may be true, Jack, but Edmund said that the movie played in QuickTime Player. So his problem is most likely not a bug in QuickTime, though I can't say for certain.
    And as I said above, I have no problem playing Sorenson-encoded content on my Intel-based Mac with QuickTime 7.1.5, so more details about your content and setup (including any third-party codecs you may have installed) so that people can determine what the difference might be between the content that plays and the content that does not, or what's different in the systems, would be helpful, I'm sure.
