| Updated the Analysis to handle System Partitions with no Label, and System Partitions that are larger than "integer value of property" can handle. | |
 |
|
| Only "C:" appears to have a label. | |
|
|
| Actually, the issue may be that on my system I am booting Windows 8 using EFI. I have a 300MB "Recovery Partition" and a 100mb "EFI System Partition" and then the "C:" partition which is "Boot, Page File, Crash Dump, Primary Partition" | |
|
|
| Yes, it is worse to put WMI inspectors in the analysis' relevance since it will be constantly evaluated, better to be handled by the results error handling code. | |
|
|
| Question, if you can give a reading on this. Since WMI inspectors are expensive, am I worse off putting WMI inspectors into the relevance of the Analysis (which I believe would be constantly evaluated) versus handling multiple WMI inspectors in the Analysis Results (which in this case I've tuned down to periods of 1 day or 12 hours)? | |
|
|
| Yes, I'm looking for a particular edge case. Using Microsoft Deployment Toolkit to refresh the machine, MDT placed the boot.wim file on that partition and left it there post-deployment. This resulted in a System Reserved Partition that was too full to create VSS Snapshots and caused subsequent System State backups to fail. I needed a way to identify System Reserved Partitions that were nearly full. Does your Windows 8 machine have a System Reserved Partition (it would be visible in DiskPart's 'LIST VOLUME' command)? If there is no System Reserved partition, I see how that would error out. Maybe the right thing is to change the relevance to only be relevant to systems that have this partition; or handle the errors in the analysis results. Normally I'd like to handle that in the results (to me it's worth knowing that a machine does not have a System Reserved Partition at all), but since the WMI inspectors are expensive I think this one might be better off ignoring the irrelevant machines. | |

|
| Actually, I think the windows 8 issue has to do with "WHERE SystemVolume='True'" which seems to cause it to return no results. Taking that out will cause it return everything but the system partition. | |
|
|
| I see, you are looking for the system reserved volume with no drive letter? I didn't realize that. I could not tell what was failing, just gave no results. It might have to do with my configuration. | |
|
|
| I don't have any Windows 8 systems with which to test. Can you tell what is failing? I'm using the WMI inspectors because the built-in Inspector for the 'drives' object only returns values for volumes that have a drive letter assigned, and the System Reserved Partition by default does not have a drive letter. Are there any built-in inspectors that will examine a partition that has no drive letter assignment? I couldn't find any. | |
|
|
| Also, these don't appear to work in the debugger in Windows 8. | |
|
|
| I also have some windows specific hard drive properties here: http://bigfix.me/analysis/details/2994542 | |
|
|
| Some of these can be done using the built in BigFix Inspectors, which are faster and more universal than using WMI calls. See examples here: http://bigfix.me/analysis/details/2994572 | |
