• W700 RAID question

  My W700 is almost 4 years and service policy was released last December.

  Yesterday, the Console matrix Intel has indicated one of the disks RAID 1 (drive 0) had failed and is in mode "gradient".

  I got a new spare drive which I installed it and the table was being rebuilt.

  Somewhere after 60% (possibly after complete reconstruction), the array returned in mode "Gradient" with drive 0 showing again failed. The same drive I just replace it with a new one (rebuilt/unused).

  I'm probably looking to two HD failures or possible failure in the HD on the motherboard, BIOS RAID support?

  I won't buy another HD if it's not necessary?

  The W700 supports any flavor of SSD (no raid configuration)?

  I might consider a RAID SSD not because otherwise, the W700 has been flawless.

  Opportunities and guidance appreciated.

  I found, I got another piece of spare and it seems to work very well. I guess that the first replacement was also defective. What are the chances of that? I also ran PC diags (bootable) DR BACK on the two disks and they extracted good.

• Yet another silly question

  So, quickly followed by the post, I did earlier this week:

  http://forums.Lenovo.com/T5/T61-and-prior-T-series-ThinkPad/what-am-I-missing-overheating-fans-tpfan...

  Yesterday, I disassembled the T60 - B, cleaned the fan, memory up to 2 GB in an accident and swapped the screen with the T60 - C flexview. And replaced broken front with another Panel before broken, but this one doesn't gouge in my thumb.

  Anyway, everything is going very well, no remaining parts and screws and it now works better (and cold) than ever.

  Question is, is there a different display driver should I br running in order to take full advantage of this upgrade of the screen? Maybe I missed something, but I don't see anything on the list of drivers that jumps out to me...

  Once again, thank you!

  I think you are missing the point. The T60 has optional motherboards and option screens. Each dimension of plate came in four different styles at least. Card Intel graphics, two with ATI Radaen and two with ATI fireGL. I guess you have a 15 "model and updated since a XGA (1024 x 768) screen to a screen flexview SXGA + or UXGA. Change the screen will not involve the change of pilots, but the flexview screens use a different ups, if you don't change your xga may not be the power inverter to operate the screen to its full potential.

  PS it would have probably been better continue your old topic instead to make a new, or posted at least all the specs of your system in the new if we do not have to guess what you might have.

• BlackBerry smartphones another little question from a novice on windows authentication

  Hi, I posted a question a few weeks ago, to summarize, I recently dumped my treo for the new storm.  I enjoy them until now, but I have a question to get connected to a windows site.

  I use logmein for mobile access, (www.logmein.com), it's like gotomypc, but free and I used to be able to log in with my treo smartphone, but I'm having a problem on my BB.  I spend all the stuff (on the site of logmein) html Web page and get to the point where I have to put the password for the computer that I'm remote'ing.  The phone's browser has "Windows authentication" in the upper part, followed by three text fields, username, PW and domain.  I don't have a domain, but when I entered the username and password, I can't select the "login" link just in the middle of the page at the bottom. "

  I tried everything, he can't know.  Also, on this screen, zoom and other "typical" controls are not available, as the keyboard and a few other navigation options (none is "next" or "enter")...  Oh, and another thing, when I click on the screen where the "login" link is, it locks the keyboard back to the top and sometimes wipes all the text on the fields?...

  Thanks in advance...

  Thanks for the help, it turns out looking as if it was a problem on the side of the House Logmein.com...

• raid question 6 UCS 210

  Hi all

  We have a UCS 210 with a LSI MegaRAID 9261 - 8i 6G card.  There also have 4x146GB 6 GB SAS 15 K RPM HDD SFF.  It is configured with raid 6 with all 4 HDD in the virtual HD group.  It seems he gives me about 278 GB.  about half 4 x 146.  does that make sense for raid 6?

  We have an another c220 with with raid 5 gives approximately 1.4 to 6x300HD.  (more than half).  RAID 5 is almost identical to raid 6 and gives less than raid 5 in size.  This is why it makes no sense for ucs210 with disk HARD 4 x 146.

  If anyone can clarify this?

  very much appreciated.

  Thank you

  Hi Vsaravanamuthu,

  The values you get are expected, what you need to know is that for raid 5 you have a failure of the SINGLE player for the fault tolerance and RAID 6, you have TWO disks for fault tolerance. It would make sense that you see more large capacity of raid 5 to raid 6.   You can also find calculators of raid online that will give you and idea of the expected capacity of the raid volume (see below).

• Another quick question of CSS layout - vertical align: middle

  Just another quick on the use of CSS to the content of the page within the section of the page layout.

  On the homepage below, I have some images with text next to them:

  http://www.Haiji.jp/

  Because of the uneven text, it would be better if the text on the right and left of the four images vertically flown in space.

  (Basically like this old version of the table according to: http://www.haiji.jp/indexcopy.php )

  I don't know vertical-align: middle; doesn't really work for this, but could not get the right way to work.

  I tried variations to have an external container positioned a parent and an absolutely positioned inner container and using top: 50%;

  So for the first row for example CSS is:

  #outerWrapper #contentWrapper #content #row_one {}

  Width: 620px;

  overflow: hidden;

  }

  #outerWrapper #contentWrapper #content #row_one #row_one_left {}

  Width: 210px;

  padding: 0px;

  float: left;

  margin: 0 0 0 0; / * Sets the properties of margin for an element using the shorthand notation (up, right, down, left) * /.

  }

  #outerWrapper #contentWrapper #content #row_one #row_one_right {}

  Width: 410px;

  padding: 0px;

  float: right;

  text-align: left;

  margin: 0 0 0 0; / * Sets the properties of margin for an element using the shorthand notation (up, right, down, left) * /.

  position: relative;

  }

  #outerWrapper #contentWrapper #content #row_one #row_one_right #row_one_right_content {}

  position: absolute;

  top: 50%;

  }

  Who is not doing and maybe overloading the question.

  But if anyone can let me know how to get this vertically positioned text which would be a good thing.

  Thanks again.

  Support IE7 you need to "hack" a little: adjust the "padding-top" according to the number of lines of text, it is a. (not a good solution as supposition is working but IE7 IS a marginal browser now)

• RAID question...

  I have two in my system RAID arrays... lies in 3 x 1 TB RAID-5 (2 TB total) which is implemented using the controller onboard Marvell chip and Intel RAID software. The second is a 4 x 2 TB drive RAID-5 (total of 6 TB) inside a box external and put in place with a G Highpoint RAID card - Tech material on a PCI-e bus.

  I plan to do a thorough cleaning and a reinstallation of the operating system and programs, and my question is, can I safely do without risk of loss of data on RAID arrays? I'm pretty confident the hardware RAID will be correct, but as software RAID is configured using a software program that is installed on the operating system, I am afraid that wiping the OS (and, therefore, control software) and do a relocation will result in this RAID being ruined... thoughts?

  Since the Marvell raid is configured in the BIOS and not in the window, unless you tried to make it REALLY slow using the Windows software, you should be OK, but if you tried to make it even slower than it should be and you used the Windows software, you will lose all your material. Is not really important, because you'll have a good backup in place strategy, I hope.

  The G-Tech raid will survive a new installation, but will still suffer from the eSATA connection. I think it would be a good time to add a dedicated raid controller to improve your performance.

• Another RegEX question

  Hi, I have a question about the regular expression: If you look at the attached code you will find two examples. It is an old piece of code, but now I have to fix a bug that was discovered after a few years of use. Task: If the entry is for example C1 - C4, the algorithm needs generate a table of C1, C2, C3, C4. This should work on any digit and letter. Examples: R1 - R5, K569-K799, S2 - S3. This works very well for [letter] [number], but my regex won't work for the case now, I have to solve. If the entry is C1A1-C1A4 the output should be C1A2 C1A1, C1A3, C1A4, but I don't know what should look like the new RegEx so that it still works on [letter] [number] [letter] [number].

  You can not only use [0-9] + $ to return only the number of the end of the string?

  Regular correspondence Expression.vi will return all the foregoing the final number in 'before the game '.

  I'm sorry that I can't look at your code since I don't have a LabVIEW 2011 on my system.

• Yet an another microSD Question (it's different!)

  Hello, new Member here! (^^) And Yes, I use the search option. I have read the FAQ; and I look at the manual.  And my question was never answered.  I hope someone answer me soon!  Thanks in advance!

  PS: Can I suggest a topic "microSD (HC)" added to the FAQ?  It could include my questions and questions of other people as well. = D

  In any case... I have problems with my MicroSD Kingston 2 GB card. The card works fine on my computer, but it does not work in my Sansa Fuze 2 GB drive.  Not at all.  And Yes, I only put MP3 files on the card... not video.

  I noticed that many people had similar problems (but not exactly the same thing), so I was wondering:

  1) products Kingston are incompatible with the Sansa? Other people keep problems with cards Kingston, so I thought I'd ask.

  2) that I must have a microSDHC card? My card is a microSD card.

  3) the card must be formatted in FAT16 exactly?  One of your textbooks said I should use "FAT16 or higher"... but when I formatted in FAT32, it still does not work. "" The map was originally in FAT format, and it did not work in this format either.

  ... Not sure if this will help, but my computer is a Windows Vista. And he gave me 4 formatting options: NTFS, FAT, FAT32, exFAT.

  And if all else fails...
  4) what is the warranty for my Sansa product, just in case the microSD slot is broken?  I bought it in late July or early August of this year (I still have my receipt + guaranteed somewhere; it is irrelevant at the moment because I recently moved). I'm still in my warranty or not?

  It's a good idea to insert or remove a card when the player is turned off. The card slowly and gently.

  "What are the chances that my microSD card will get stuck in the drive of Fuze?

  I have heard talk of this never happens. My digital camera has a similar mechanism, but uses a full size SDHC.

• UCS C220 M3 raid question

  Hi all

  I have a UCS C220 M3 with 4 hard drives, when I want to create the Raid 5 is not enabled, I have only 1 or 10.

  Any ideas?

  Thank you.

  See this http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/hw/C220/ins...

  You need the software key, otherwise you will only be able to configure RAID 0,1 and 10

• SSD 4 k mount Raid Question

  In recent months the couple here, I built a fairly large ediitng platform k 4. now my only neck of the bottle is what I believe to be my camera 2. Is raid 0 but the speed is even slower, so I only for the 4 k files r3d that I am editing in first pro. I was chatting on upgrade to 2 1 TB samsung 850 pro ssd in raid 0 as the source media players. I see a significant increase on my flow with these discs for the media source?  The rest of the system is a x 5960 i7, titan x, 256 GB ssd for cache files, a 256 GB m2 for start-up and a 99 deluxe 3.1 x mobo.

  -Cheers

  This test seems very strange, as if they had a bad intel 750 or it is in a location PCIe clocked at 1 x. I wouldn't trust these results, sound out of the character. I've seen other landmarks, most of anandtech, which show that the drive intel is preferable to writing, while the samsungs are better at reading.

  This shows the intel 750 and the cards just to get the samsung 850 pro as well. in some of the benchmarks, you might imagine a raid of samsung 850 pro becomes a bit near the 750 in reading/writing, but raid will not make the difference in latency.

• Another interesting question of synchronisation in 3.3.0.747

  I have a table of table that has been designed from a database schema. The table has now been moved to a different database in another schema and changed.

  3.3, I am able to re-point of the synchronization model with the data dictionary for the new database connection, but the result is the wizard says the table isn't in the new database and therefore should be removed from the model.

  I executed the script of meta-data table clear that Philip wrote earlier, but get the same result.

  How can I get is the tool to recognize the table in the new database, but the model needs to be updated?

  Hello Kent,

  You can change the schema in the model and use synchronization utility or can use wizard 'import of data dictionary.

• Another recursive question

  Hello
  
  I'm doing a program that generates the n-bit Gray code. Binary thinking, also known as the Gray code, is a binary numeral system where two successive values differ in only one bit.
  
  Another explanation would be - a bit grey n code is a list of 2 ^ n different n-bit binary numbers such that each entry in the list differs just slightly from its predecessor.
  
  If I want to generate 1-bit gray code that would be:
  
  * 0 *
  * 1 *
  
  2 - bits would be:
  
  * 0 0 *.
  * 1 0 *.
  * 1 1 *.
  * 1 0 *.
  
  
  3 - bits would be:
  
  * 0 0 0 *.
  * 0 0 1 *.
  * 0 1 1 *.
  * 0 1 0 *.
  * 1 1 0 *.
  * 1 1 1 *.
  * 1 0 1 *.
  * 1 0 0 *.
  
  and so on.
  
  
  That's what I have so far:
  

  public class GrayCode {
  
       static void genGC(int n){
            
            if(n == 0){
                 System.out.println(n);
            }
            else{
                 genGC(n-1);
                 
                 genGC(n-1);
            }
            
       }
       
       public static void main(String[] args) {
            
            int a = 1;
            
            genGC(a);
  
       }
  
  }

  Thus, in the case 1-bit gray code the program above would be output:
  
  * 0 *
  * 0 *
  
  for the 2 - bit code:
  
  * 0 *
  * 0 *
  * 0 *
  * 0 *
  
  etc.
  
  Any ideas or advice what to do to go further are greatly appreciated.
  Thanks in advance.

  blias says:
  Edit: Actually not sure on the baseline scenario. Thus, when n == 0, we create a String [empty].

  What he has is suppoesd be: we create a String [] containing a single element, and this element is an empty string, "". However, for me, your comments sound 'empty String []' love new string [0], a String [] without items.

  So for n = 0, the list of channels is an element, «» Logic says that for g (1) we take that a single empty element for g (0), copy it and reverse the trend. So now we have "" and "" as the two pieces, which is the inverse of the other. And then add us "0" to the first "" and the prefix "1" to the second "", giving us '0', '1 '. And so on...

  (2) I leave you to think about why the numbers 1, 2 and 5 above call methods that return values, while 3 and 4 use all the return values. If you get stuck, however, I'll explain it.

  Sometimes I get confused whether to create a method that returns something or to have Sub. When I work on other problems, sometimes I'm in doubt - why do I need a method that returns the value or else vs vacuum and vice versa. I think more practical, the understanding of this would eventually come.

  In this particular case, 1, 2 and 5 are creating new objects, so call us a method that creates the object and returns. For 3 and 4, we take just existing bays and edit their content. Nothing magical here. Just going by what says the abstract steps.

  As I said earlier - for me it is more difficult to break down the problem to the smaller, small problems to break the smaller yet more and so on until I get simple steps rather than coding real itself.
  Do you know if there is no method to this approach to the failure or is it just common sense?

  I can't give you a magic formula. For me, it's just a matter of logic, common sense and experience. Most likely (mumble) years of experience let me forget a lot of the details of the trip.

  jverd, you're the greatest teacher I've ever had. Seriously.
  I do thank you again for your time and for all. :)

  Meh, I have good days and bad as someone else. Glad to be useful! And thanks for the compliment!
