Follow up question about interpreting smart data test on 160GB classic

I posted this question regarding the problem I am having with my 160GB ipod classic:
http://discussions.apple.com/thread.jspa?threadID=2153948&tstart=0
It appears noone is able to help me, so I have found some more information:
In short, itunes will not write to my 160GB ipod once it reaches about 35GB / 160. Windows will write to it, but only at 500KB/sec rather than the usual 19+Mb/sec. It just crawls once it hits that point. After following some advice online I came up with the following results using the HD tests in diagnostic mode.
smart data test:
retracts: 138
rallocs: 563
pending sector: 55
poweron hours: 1016
starts/stops: 267
temp: current 26C
temp: min 19C
temp: max 53C
and for the HDD spec test:
sno: (not sure if i should post a serial number?)
FW Revision: NB100-05
LBAs: 0x12a19eb0
These are the only tests that show up under the I/O HardDrive section. Should there be more? It seems like there might be from what I read, but I am not sure.
Anyway, any help interpreting these results would be greatly appreciated.

Your drive is probably toast. Compare your SmartData stats with mine:
Retracts: 844
*Reallocs: 12*
*Pending Sectors: 0*
PowerOn Hours: 2037
Starts/Stops: 830
Temp: Current 29c
Temp: Min 10c
Temp: Max 50C
I've only 12 remapped sectors and none pending. From the Wikipedia S.M.A.R.T. article:
*Reallocated Sectors Count*
Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area). This process is also known as remapping, and "reallocated" sectors are called remaps. This is why, on modern hard disks, "bad blocks" cannot be found while testing the surface – all bad blocks are hidden in reallocated sectors. However, as the number of reallocated sectors increases, the read/write speed tends to decrease. The raw value normally represents a count of the number of bad sectors that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate.
*Pending sector count*
Number of "unstable" sectors (waiting to be remapped, because of read errors). If an unstable sector is subsequently written or read successfully, this value is decreased and the sector is not remapped. Read errors on a sector will not remap the sector (since it might be readable later); instead, the drive firmware remembers that the sector needs to be remapped, and remaps it the next time it's written.
I'm sure you'll find the counts go up if you try to do a surface scanning disk check. Sorry it's not better news but at least you know where the problem lies. Assuming your iPod is out of warranty it's probably time to get your iPod refurbished with a new drive or to buy a new iPod.

  • Question about Rescheduling Start Date of a Task

    Question about Rescheduling Start Date of a Task
    I'm trying to determine whether the 'Reschedule' action is appropriate to my situation...
    I have a service that consists of 4 tasks.  The first 3 tasks will be completed immediately and then the request's 4th task will sit in a queue for about a month so that all of these requests can be grouped together and fulfilled during a few overnight work sessions.
    While the 4th task is waiting to be fulfilled, the technician will be contacting the requestor to schedule the work to be done sometime during a 3 day window.  The technician needs to specify which of the 3 days each request will be worked on.  I'm not sure if I should store the date in a service form field or have the technician reschedule the task so that the start date of the task is set to one of the 3 days.  If I use the reschedule feature, are there any downsides?
    The advantage of using the reschedule feature is that the scheduled start date can be displayed in ServiceManager's task list and can therefore be sorted on and queried.  This wouldn't be possible if I stored the date in a dictionary field on the service form.  In that case, I'd have to use custom reports to group the tasks by start date.
    Please let me know your thoughts...
    Thanks,
    Scott

    This strikes me as a very good use of this feature, since your need to to have the date for this task rescheduled/reflected in ServiceManager. This is the specific effect of using this feature.
    For the benefit of others reading this post, remember: this rescheduled date will not change the due date for the service.

  • Less dumb follow-up question about super/sub classes in WDJ?

    This is a follow-up question to the question which Maksim answered in this thread:
    Dumb question about super/sub classes in WDJ
    Question:
    Is there any kind of weird C++-like statement that you can put at the top of a WDJ module to force the module to interpret any reference to superclass A as a reference to some specific subclass B of A ???

    David,
    1. Java has no preprocessor, so C++ tricks are not available. Also I would not recommend such tricks even in C++ if you don't want to turn your colleagues working with same code into personal enemies.
    2. The phrase "easier to create a WDJ custom class loader " makes me smile. First, it's not that simple to interfere WDJ class loading scheme. Plus custom class loaders is not trivial Java topic per se.
    3. The problem "replace all A-s with B-s" is typically solved using one or another GoF creation patterns, like <a href="http://en.wikipedia.org/wiki/Abstract_factory_pattern">Abstract Factory</a> or <a href="http://en.wikipedia.org/wiki/Factory_method_pattern">Factory Method</a>. You may use them with custom class loader, if you really want to
    By the way, all UI controls in WD are created using Abstract Factory (role played by view). So you may use this as good example.

  • Follow up question about image not looking good in canvas-Shane?

    I guess this is a follow up question for Shane....
    You wrote this in response to someone a year ago which helped me out.
    Shane's Stock Answer #49 - Why is the quality different between what I see in the Viewer and what I see in the Canvas?
    Well... the viewer is just that-- a viewer. It will display anything that fcp will recognize as usable video or graphics. The canvas is a viewer too, but at the pixel dimension specified by the settings of your project and sequence.
    For example, if your graphic or footage is much higher resolution than your 720x480 DV sequence, FCP is interpolating down your file to fit the settings of the sequence. Usually this makes it look not so hot. DV is a 5:1 compression working with a 4:1:1 color depth. Your pristine picture images and graphics are being crushed.
    Same with picture files. HIgh res pics now adopt the sequence settings and will render to those specs, and most likely they are not as high quality.
    So, based on your answer, I made an HDV sequence, dropped my DVCPro50-NTSC footage and my tiffs into the sequence and now the stills look great. Is this an okay workaround or do you have another suggestion? I'm worried about this HD sequence taking too long to make a compressed QT from in the end.
    Thanks!

    Photo JPEG is a good option.  But this all depends on what your final output will be.  If you are going to make a DVD, then that is SD, so using an HD sequence setting makes no sense.  Photo JPEG is good, but not realtime in FCP.  DV50 or ProRes NTSC are good options.
    Unless you are making an HD master...in which case ProRes 422 for HD is good

  • Follow-up question about forms and SharePoint Online

    I asked a question about life after InfoPath earlier, and got a good answer:
    http://social.technet.microsoft.com/Forums/sharepoint/en-US/fb23b3d9-8a09-4267-aab5-09929f6a3082/life-after-infopath-seeking-advice
    After looking at all of the limitations of SharePoint Online, I'm wondering how developers are dealing with the limitations. Lets say you are asked to develop something that has complex logic, including fetching data from external web services, dynamically
    displaying parts of a process to people depending on role, and ending up with a printable document. In our on-premises environment, InfoPath is well suited to this task, with some code behind for some things. Or, if not using InfoPath, we would use application
    pages and workflow.
    Neither of those are available in SharePoint Online, so what would you do?

    Some things, such as the conditional display of content, can be done via JavaScript. More advanced items, such as integrating external web services would likely require a SharePoint "app". A SharePoint app is essentially a link to a separate site
    that is running an asp.net web app (or PHP, or whatever). This asp.net site can do anything it needs with any web services, or conditional formatting, or anything. Because it's registered as a SharePoint app, it can also call back into the SharePoint site
    and work with data. So, a SharePoint App could present the user with a robust form that simply sends the data back to a SharePoint list. The SharePoint app can also be surfaced on the SharePoint site itself in an iframe, so the user won't know that the form
    is hosted by another server.
    By the way, the ideas behind the app model permeate the entire SharePoint environment: instead of having the SharePoint server itself run all kinds of custom business logic, that workload is handled by other servers, so the SharePoint servers can be focused
    on running the core bits of SharePoint. InfoPath puts a large load on the servers, so it's out.  XSLT list views also put a load on the server, so they're also out. SSRS is an amazingly fantastic tool, but is not supported in the cloud (and there's no
    alternative). Timer jobs, event handlers, workflow, and many other things have been re-architected to take the load off the SharePoint servers.

  • A question about UDA and Data-Forms

    Hi all,
    I have a couple of questions about UDA. I am using Hyperion Planning 11.1.1.3m, and when I desing a Data-Form I would need to use the UDA I asigned for the Entity dimension: is that posiible?
    The other question is, when creating a Substiution Variable in Essbase I use the function @UDA (+dimension+, "MemberA"), but when using this variable in the Data-Form, it does nothing at all(in fact, it is been detected as an error). Why is that happening?
    Thanks a lot

    Use an attribute dimension to achieve what you are trying to do with UDA's in a data form. An attribute dimension will allow you to filter on members in the base dimension by a specific attribute the same way a UDA will. You can create the attribute dimension in the dimension editor in Planning by selecting the base dimension (Entity) and then select the custom attributes' button. Check the dba guide for a step-by-step approach.
    With regards to the subvar, are you trying to add the function as a value of the subvar when you create it in EAS? If so, this is not allowed. What are you trying to do with the subvar on the form? Subvars are supported in data forms as part of the member selection for a dimension. For instance, you can set up a subvar called CurYear and set the value equal to FY11 for the Fiscal Year dimension. In the data form you can set the member selection for the Fiscal Year dimension to CurYear. When the user opens the form, the member FY11 is returned.

  • Question about exporting FBL3N data in Pivot table format

    Dear all
    I have a question about the "exporting file" function of ECC 6.0.
    We started to use ECC 6.0 system, and it appears that we are no longer able to export "FBL3N data" to a local PC in pivot table format.
    Is there a way to do it?
    We used to be able to do so when the system is 4.6.
    I appreciate your support!
    Kind regards

    Dear:
                 You can do that. Execute report FBL3N with desired GL account in it. After when report has been executed right click on it. There will be an option Spread Sheet. Select all available format. In drill down select 08 (Excel in existing XXL format) and press OK. There you will get pivot table option for downloading., Hope this will help you resolve your query.

    Sorry, not much expert here on SSD mods, you may get better response in the iPod Mod forum.
    It has a lot of posts on successful SSD swaps and also some nasty experience on SSD which does not work on some iPod.
    Read through the forum and learn together with them, and avoid frustration of getting an expensive SSD, which the iPod firmware can't recognise, and also there is not enough voltage to power up those old SSD using 5volt rails, iPod hardisk uses 3.3volts rails.
    Good Luck!.

  • Question about Index in data selection

    Hi experts,
    I am reading the documents about index today and find there are some questions confused me. Plz help, thx!
    1 What is the technical structure of index?
    For example, I have a table ztable with 5 fields, F1(key), F2(key). F3. F4.F5. If I create a index on F3,F4, the system will create a copy of this table. Is the structure of this copy as follow?
    F3, F4, pointer(for the lineno of the recorder)
    So this copy will have fewer lines than the ZTABLE and is sorted. If the DB optimizer choose this index in selection, it will be fast for the 2 reasons?
    2 By what is the sequence of the fields in the index determined? I read a BLOG about permance, the author make a example with DB05, and say if the distinct values of certain field is between 1-1000 lines, it is good to set a secondary index for the field.
    I wonder, if the F3 has only 5 distinct value for all the data in the ZTABLE, and the F4 has 100 distinct value. Which one should be the first field in the index and why?
    Thx!!~

    You seem to be correct for some but not all.
    Struture of index will
    for unique key index F3, F4, row id of database
    it could have only one row id when your where condition match with the index then it goes to only index table first and read the row id and read record directly from the row id.
    But for non unique key table store all the F3, F4, row id of record which math value of F1 and F4. It can have multiple value.
    When your where condition math with condition partially ie left part of the key or whole part key then read all match record from the index table and then read the database physical table and check for addation where condition if any.
    Index is determine on basis of the where condtion which is most left part of index will match.
    if your where condition F4 and in your index has f3 f4 then index will not consider, It create gap between index condition and read whole table database. But if you consider f3 then only it consider the index to read because it match the left most part with index fields.
    For more details How to create secondary index ? Search for blog in sdn I reply many time.

  • Question about GG if Data Center Fails

    Hi i came across a question from my team about, what happens to Golden Gate replication when a data center failure occurs or an automatic switch-over to VCS cluster happens?
    Automatic switch-over to VCS cluster did happen in our environment once, when our NIC card was not working for our Primary server in Production VCS Config shut down the primary node and automatically switched over to failover node in VCS cluster.
    I am also looking into option what will happen to on-going Extract and Pump process on source? How will i be able to syncronize the residual data from source side to target side, if such things happen?
    Any comments or experience will help me.
    Thanks

    All of our filesystems on primary gets failed over to failover cluster node, like how it happens with database bins and data files.
    We have tested it and verified if we can start the Golden Gate after failover happens on failover node.
    Thanks

  • Question about accesing binary data

    If I have a text file saved on my harddrive, how is it really stored? Can I access the raw binary data of the text file?

    Oh ok so I get the ascii values of the text. No, you get the bytes in your file. Whenever you read, through Java or anything else, you get bytes.
    The interpretation of those bytes as ASCII or Unicode or a Word file or an mp3 or whatever occurs after the bytes are read.
    And I
    take it that the pc stored the values as 1's and 0's.Huh? It's always just ones and zeroes that are stored. The letter "A" is never stored. It's just the binary pattern that corresponds to the number 65, which is interpreted in some contexts as a captial A.
    So is 77k of text sotred as 77k of binary on my pc?The number of bytes you'll get this way is equal to the number of bytes in the file, with two caveats:
    1) What I said in my last post about the file size potentially changing between checking size and reading.
    2) File systems allocate blocks--usually 512 or 1K bytes, so if your file is, say 1600 bytes long, it might show up as 2k in in Windows Explorer, but the number of bytes read will be 1600.
