Check cdrom for read errors

Hello all,
may be this question sounds stupid, but is there any way to check cd disk for read errors in Solaris ?
I have Solaris 9 installed
thanks !

You didn't mention whether the CD was bought or burned from an iso image. If you have access to an md5sum of the iso image that was used to burn the CD, then you can verify the CD content against the image. There might be a clever tool to automate this, but I usually just md5sum the iso image, then do the same with the CD itself.
To use md5sum on the CD: assuming it's already (auto)mounted, check what /dev/... name it corresponds to by looking at the output of mount. Then umount the CD but don't eject it. Run md5sum (or digest -a md5) on that /dev/ pathname.
If you don't have a verification source, then I suppose you could just get Solaris to scan the entire CD contents (e.g. use "tar cf -" on the CD root and redirect output to /dev/null) and then look for any I/O errors in the system logs.

"open for read error" message

A recent firmware update (2.1 for MAcBooks) caused many of us to lose use of our superdrives. Someone figured out a fix that involved "flashing" the drive by running a program he wrote from Terminal. It worked for quite a few people but when I tried to run it instead of executing the program the message "open for read error" was returned. The command was "./simple_flash 0 UJ857-KBVB-MBP-rpc1.dat" which was supposed to start the simple_flash executible which referred to or used the .dat file.
Does anyone know what the "open for read error" is telling me? How can I resolve whatever it is that is preventing execution.
Thanks very much. Many are buying new superdrives to solve this problem but that is expensive.

I would say to take your machine into an Apple Store, but judging by your profile, I think that might not be feasible.
Where are you running this from? I downloaded it and looked at the source and that error just means that it can't open the dat file. Actually, it means that it can't even find the dat file. In the Terminal, you must use "cd" to move to the directory where the "simple_flash" executable and the .dat file are located. Do an "ls" and, if they are both listed, it should work.

Possible fix for read error

Wow would have never thought of this, I've updated my phone today and couldn't for the life of me work out what this bleeping and read error message was, unticking all notification boxes I could find and after all this thank god I stumbled on this it was indeed my arm card that has a chip so a huge thankyou!!!

@Foxxi - Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

How to check code for syntax errors

How do I check or validate my html code in dreamweaver. I wish to see if all the braces and tags are closed or not
please guide me

Hi There:
You can check to make sure the tags, parentheses (( )), braces ({ }), and square brackets ([ ]) in your page are balanced. Balanced means that every opening tag, parenthesis, brace, or bracket has a corresponding closing one, and vice versa.
Check for balanced tags
Open the document in Code view.
Place the insertion point in the nested code you want to check.
Select Edit > Select Parent Tag.
The enclosing matching tags (and their contents) are selected in your code. If you keep selecting Edit > Select Parent Tag, and your tags are balanced, eventually Dreamweaver will select the outermost html and /html tags.
Check for balanced parentheses, braces, or square brackets
Open the document in Code view.
Place the insertion point in the code you want to check.
Select Edit > Balance Braces.
All of the code between the enclosing parentheses, braces, or square brackets is selected. Choosing Edit > Balance Braces again selects all of the code inside the parentheses, braces, or square brackets that enclose the new selection.
And also make sure to validate your HTML code at - http://validator.w3.org/

Cisco Security MARS 110 error - sfdisk:Cannot open /dev/sda for reading

HI when installing the MARS ver 6.0.1 we are getting this error sfdisk:Cannot open /dev/sda for reading, but found that this a bug for that ver BUG id : CSCso92379 - Cannot open /dev/sda for reading" error seen on installing Gen1 GC
So we tried installing the ver 5.3 now also getting the same error, pls let me know is this a hardware issue or a bug

It sounds like there may either be a problem with the RAID controller [configuration] or, though unlikely a hardware failure. You'd need to check the RAID controller BIOS to see if there's a hard disk drive problem or RAID configuration problem. Also check RAID controller is damaged as disks are not recognized at all.
Rebuild the Raid and reimage the appliances.

BW: Not getting Dump For Program error in Process Chain

I have one issue regarding Master data loading issue in BW(3.5).
My business flow like we have received data from server A and Server A extract data from Server B and
Server B which is extract data from source(R/3).
Flow like this R/3-->Server B-->Server A(ETL) -
> My Server.
We have a mater data process chain and that chain we have have the source system Server A but in the process chain one process is there which is fethces data like global transport e.g UOM,factory calender etc through Custom program directly from Server B.
Oneday what happened On that process the process chain Yellow since more than 16 hrs.Once nextday process chain trigger the process chain runs sucessfuly.
But lastdays process chain paticular process stills remains yellow?
We are not getting any dumps and even if from Server A there is no logs then anyone could please tell me what is reason and how to solve it.
Note: it will be helpful for me if any one know how to check dump for program errors in Process chain as narated issue.

Guys, I am also facing the same issue.
When DTP is completed successfully, it has the job log blow :

The question is, why the program RSBATCH_EXECUTE_PROZESS is not scheduled. Is it because there is no free resource? Or poor response from SAP ECC?
Finally what does "EXTRACTION OF DATAPACKAGE 000001" mean? Its not scheduled?

Every time I TRY to start firefox 18-19 I get an error message : Firefox has stopped working - close the program and check online for a solution - or - close ..

Every time I TRY to start firefox 18-19 I get an error message : "Firefox has stopped working" - "close the program and check online for a solution" - or - "close the program" this happens TWICE every time I try to start firefox. Eventually after a random number of tries firefox will start normaly. I am useing firefox 19.0.2 now bit I belive it started when I upgraded to firefox 18 but am not sure, it might have been when I upgraded to firefox 19 ... but it has been happening for a very long time and I cannot find any helpfule solutions online.
I have tried a Clean reinstall but it did not help.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!

Unable to check plugins for 2 weeks now-error message-went to "help" & was warned I am using outdated version-so went to update but not available....any ideas? I am computer literate so you don't have to over-simplify your answer ; ) Thanks!

I keep rec. an error message every time I try to do a plugin check. It says "error finding service" and asks me to try again later. I have been trying for a couple weeks now and still get the same error. I clicked on "help" and was brought to a page that told me I am using an "insecure version" of Firefox....(LOL "INsecure...like it's scared, not sure what to do?? Shouldn't that be UNsecure?) Anyway, I thought I had the most recent version but maybe not so I clicked on the link to update Firefox. That took me to a page that told me all about how Firefox automatically updates unless I opt for it NOT to do this (I have not opted out of this feature) etc etc etc.....and there is no button to click to update now. I am unable to rectify this problem and I think some of the plugins ARE out of date but because of the error message I keep getting I can't check on them or update them. Any ideas will be greatly appreciated. Thanks!

[svn:osmf:] 11848: Added check for argument error DRM subsystem throws while generating a DRMContentInfo Object .

Log Message:
Added check for argument error DRM subsystem throws while generating a DRMContentInfo Object.
Modified Paths:
    osmf/trunk/framework/MediaFramework/org/osmf/drm/DRMServices.as

Well, I can tell you that this kind of error is not OS related, but rather a HW thing. It happens where there is a general detection of something going wrong. Sometimes it can happen randomly and might not be an indication of a problem. But sometimes it can be caused by things that are improperly functioning within the system like bad capacitors.
Unfortunately I don't really know what to do about such things except give you machine a proper inspection. But if things are working fine, and continue to do so, I wouldn't worry about it. If it becomes a regular occurance, then I'd worry.

Check Form for Errors When Digitally Signing?

Greetings,
I am using LiveCycle Designer ES3. The target version of my form is Adobe version 8.
My form is initially completed by a document generator, then forwarded to a reviewer. The reviewer will then use the form to document his/her determinations (approved, disapproved, etc) of the material the document generator submitted for review. Once the reviewer is done with his/her determinations, he/she digitally signs the document using the signature field created in LiveCycle. Once the document is signed, it is locked down and unable to be edited further.
Is it possible to have my form check for oustanding errors when the reviewer attempts to sign? Also, is it possible to not allow the reviewer to sign if errors are present?
Thank you in advance for your help.

To clarify, the document generator only fills out a few fields. The reviewer completes the rest of the form, so the reviewer would be the one making the errors.

Although possibly not related to your problem, I have to remind you that the version of Firefox you are using at the moment has been discontinued and is no longer supported. On top of this, it has known unpatched bugs and security problems. I urge you to update to the latest version of Firefox, for maximum security, stability, performance and usability. You can get it for free, as always, at [http://www.getfirefox.com getfirefox.com].
