  • Cannot read/write a second drive in MBP 13

    - by Carlos
    I changed my original HDD for a SDD earlier this year and I just got one more SSD for my MBP 13 (2012) that I used to replace DVD drive. I'm using Mountain Lion. The SSD looks to be recognized allright, but I can't format it. Then I removed the main drive and tried the new one as the main drive and did the boot using a USB drive with MAC OS and everyhing worked as it should (like I just had one drive). However when I bring the first drive back together with the second they both show up but I can't use it. Seems like I have no permission, but when I look at it's properties it says I can read and write to it. Any ideas? Thanks a lot!

    - by FernandoSBS
    I have a plasma TV with USB input (can play divx and etc) but what I would like to do is use a software to turn a folder in my notebook HD (windows 7) into a USB Mass Storage device, so that I can connect the TV to the PC using a USB cable so that the TV recognize the PC folder as a flash drive / usb mass storage. is seems MAC has something like what I need: http://support.apple.com/kb/ht1661 So there must be a similar to windows!

  • State Transition Constraints

    Data Validation in a database is a lot more complex than seeing if a string parameter really is an integer. A commercial world is full of complex rules for sequences of procedures, of fixed or variable lifespans, Warranties, commercial offers and bids. All this requires considerable subtlety to prevent bad data getting in, and if it does, locating and fixing the problem. Joe Celko shows how useful a State transition graph can be, and how essential it can become with the time aspect added.

  • My new hard drive doesn't have rights on my old one?

    - by Allan
    Until recently I had a 1 TB hard disk with Windows 7 on it, I have bought myself a SSD, removed the old harddisc and installed Windows 7 on my new one. After that I put back the old hard disk, and formatted it, now I could use that as backup and to keep files on. Nice, right? Well I was updating .Net framework through Windows update, when it stalled. I noticed some space was used on one of the drives on my secondary 'previously primary' hard disk. Apparently it was the .Net framework, trying to save some temporary files on my secondary disc, because it was the one with the most space. It was like it didn't get access. I cancled the installation and rebooted the computer. Now wanting to remove the temporary folder on my secondary harddisk. It told me. "You don't have access by SYSTEM", I don't understand, my user is administrator, its the only user there is and at the same time I can remove and delete any other folder on that drive. I'm gonna go a little pseudo here. But it feels as if the computer treats the old harddisk as protected from tampering by the new SSD. Also, I feel I should mention, they are both listed as primary, ... primary 0 and primary 1. Both using SATA cable. My old hard drive was partioned into 3 drives. 2 of them said the current owner was 'Administrator/myPCname' and the third one said the current owner was 'SYSTEM' I changed them all into the only one that I could pick from the list, which is my user since the 'Administrators/myPCname' wasn't exactly wrong.. could it be that they were somehow still attached to the old OS?.. the fact is I named my computer the exact same thing as it was called before installing a new windows.. so I can't really tell if its an old ownership or not. Also.. I'm currently logged in as 'myname' and I'm administrator.. now trying to delete the previously mentioned files.. it says 'you need access from 'myname' – and it can't delete.. That seems really messed up, I mean I'm logged in as the name it wants me to use. Is there maybe someway I could reset all the users on my computer? Or create some default? I don't know – I just want it to take a form I have always known, from a standard Windows point of view.

  • Have optical drive connectors changed in the last year?

    - by Zippityboomba
    In early 2010 my motherboard freaked out, and I was able to drop in a new board and connect my two DVD drives that were initially bought in 2005. Tonight my new components arrived to build my next system, and I figured I'd just reuse the old DVD drives. Surprise, the long flat connector cable has no mate on the new motherboard. Reckon I'll just pick up a new DVD drive for $25, but what gives? Thanks!

  • How to mount NTFS drive at startup

    - by user3403
    I'm not even sure if this is the right question, but basically I have a partition with Windows 7 on it (named Acer in my Ubuntu places menu) that I have to click on every time I start the computer in order for my music to come up in Rhythmbox, since my music is stored on the windows drive. What I want to do is have the NTFS drive "Acer" mount automatically when I start the computer, so my music is there automatically.

  • Windows 7 won't recognize my second hard drive after reinstall

    - by Shadur
    I recently suffered a total hardware crash on my windows C: drive. Fortunately, I had a spare disk on hand and set about reinstalling. For some reason, during the install it decided to declare my second windows drive as the booting drive, but once the installation was completed it completely and utterly refuses to acknowledge the filesystem -- I'm not even seeing a drive letter, while it /does/ find the linux partitions on the other two drives (even if it can't read any of them). My first (and most important) question: How can I get windows to re-acknowledge the drive, preferably without losing all the data on it? My second question: How can I tell windows to set up its boot loader on the new C: drive?

  • Using AppFabric session state provider, does each session get its own region?

    - by goombaloon
    I've been playing around with AppFabric Beta 2's session state provider. It appears that each new session get its own region (named "Default_Region_XXXX" (where XXXX is an apparent random sequence of numbers). If I understand regions correctly, it appears that each region is tied to a single cluster host, leaving a single point of failure. Why is each session being given it own region? Also, do sessions eventually timeout and clean themselves up in the cache or is that behavior just inherited from the cache settings? I'm wondering (if in a production application scenario), if one would use a separate named cache for session state apart from other application caches? Thanks.

  • How to Maintain per-Client State in a WCF Service?

    - by tbischel
    I've created a WCF service in which I would like it to maintain state between calls from the client. I figured the easiest way to do this was to add this attribute to the service: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] since this is supposed to keep a separate service alive for each client over the life of the client proxy (or timeout in the extreme case). I also added a test function that tracks a list of user inputs, and spits out a concatenated string with all the inputs over the life of the service. When I run this in the test client generated by visual studio, I find that the list I was using to hold past data is reset with each call. Is there something else I need to do to maintain state per session?

  • Internet connection in android emulator always displays connected state

    - by ganesh
    hi I tried in many ways to check Internet connection in my android emulator ConnectivityManager conMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo info= conMgr.getActiveNetworkInfo(); if(info != null || info.isConnected()) { Log.v("NetworkInfo","Connected State"); } else{ Log.v("NetworkInfo","Not Connected state"); Log.v("Reason",info.getReason()); } even if i disable Internet connection in my system ,my code seems to display Connected state so i guessed this may work if ( conMgr.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED || conMgr.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ) { Log.v("Congr","Connection Present"); } else if ( conMgr.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED || conMgr.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED) { Log.v("conMgr"," No Connection"); } but the above code also displays "Connection Present" even when i disconnect Internet cables. .Please help to find a correct way to do this .I have ACCESS_NETWORK_STATE and INTERNET permission in my manifest file

  • Clean up State field with T-SQL?

    - by Pselus
    The State field in our database is a mess. There was no validation when it was filled so we have everything from two letter abbreviations to full state names to misspelled state names to "test" and "xxxx", etc. I am not going to try to handle everything, but for sure I want to fix the correct state names to abbreviations. I have a list of valid state names and abbreviations, but I don't know how I can do this: UPDATE Table SET State = ('AR','AK') WHERE (SELECT * FROM Table WHERE State IN ('Arkansas','Alaska')) Basically, can I update a field to be something from a list by the location it is in another list?

  • What's causing “Session state has created a session id, but cannot save it because the response was

    - by mike nelson
    I'm getting this fault intermittently. I found this link which summarises fairly well what I was able to find on the Google: http://www.wacdesigns.com/2009/02/03/session-state-has-created-a-session-id-but-cannot-save-it-because-the-response-was-already-flushed-by-the-application/ Basically it says you can try setting the web config setting DisplayWhenNewSession, or try kicking the session state thing into life by getting the Session.SessionID in the Session_OnStart. But does anyone: a) have an explanation for this or even better, b) have a tried and tested fix I realise that I can't flush the response after doing anything that would affect the http response header. If I did this it would cause an error every time but this is intermittent. The SessionID should surely be created by ASP.NET at the beginning of the page response automatically, before anything in the ASPX page or the Page_Load (which is where all my flushes are called).

  • I have a bunch of CHK files on my USB Drive that used to be my stories that I saved on there. How do I get them back?

    - by Susana
    Ok, so I am not sure why, but my USB flash drive isn't showing all of my stories that I typed and saved. It might be because I removed the USB flash drive without ejecting it safely. All of the data was there on my flash drive, I just couldn't see it. The capacity was almost full so I'm pretty sure the data was there. So, when I decided to run and check to see if there were any problems, the computer found that there were. I think it found my files, but now they are CHK files and I don't know how to get them back. Can someone please help? This is my life's work here!

  • How to partition Seagate FreeAgent GoFlex 2TB hard disk?

    - by balki
    Hi I bought a new Seagate 2TB external hard disk. I opened the drive's application in my virtual windows, did product registration using the application present in it. I have few questions on how best to use it. The drive by default has some files and folders - setup.exe, System Volume Information, USB 3.0 PC Card Adapter etc,. I copied all the files to my laptop. Is it safe to delete these files? It has a dash board for windows which allows to tune power options, test the drive etc. Will I be able to use the dash board if I put back all these files and mount on windows again? I want to partition and format the hard disk. Data I like to store is Around 10 to 20 GB Files - Virtual box images. Around 4GB Files - Dvd images. Other Movies and personal Files. What is the best filesystem to store very huge files like 10 to 20GB files. So that they are written and accessed fast also best uses the drive's capacity. If I leave one of the partition as ntfs and others to different files systems, will it be able to mount on windows and Will I be able to use the device's dash board? Note: I dont need any encryption for my data. Any other advice on using the hard disk is also welcome.

  • Boot problems w/ External HDD

    - by JeremyT
    I'm having a problem with booting a live image off of a USB Hard Drive. I used Startup Disk Creator to make an Ubuntu 11.10 live image on a partition on my external so that I can use it on various computers. I set it up with ~4GB of persistent data So far I've tried it on two computers. One, a Dell, will boot to my external but it loads the select boot device very slowly. It hangs on a screen with an underscore for up to 5 minutes until it allows me to select which drive I want to boot from. After that, it works great. However, on my primary computer it doesn't work at all. It's an Acer from 2009 and it won't even recognize the drive. I don't see it anywhere in BIOS or the select boot disk list. The light on the external will come on at boot just fine so I know it's powering it at this time. Both computers worked perfectly with my 4GB flash drive that I had partitioned half and half (1st half FAT32 and second Ubuntu 11.10 live)

  • Asp.NET ReportViewer “report execution has expired or cannot be found” error when using session state service or SQL Server session state

It occurs to any asp.net page in the application, rendering the entire application unusable until the user gets a new session. The cause of the problem is that the ReportViewer uses session state. When a page retrieves session from any out-of-state session, the session variable of type Microsoft.Reporting.WebForms.ReportHierarchy is deserialized from the session storage. The deserialization could cause the object to connect to the report server when the report is no longer available. The solution is simple but not pretty. We need to clean up the session variable when the report viewer page is closed. One way is to add some Javascript to the page to handle the window.onunload event. In the event handler, call a web service to clean up the session variable. The name of the session variable appears to be randomly generated. So we need to loop through the session variable to find a variable of the type Microsoft.Reporting.WebForms.ReportHierarchy. Microsoft has implemented pinging between the report viewer and the report server to keep the report alive on the server when the report viewer is up; I hope they will go one step further to take care of this problem.
