corrupted shadow files and huge winsxs directory

Hi, and thanks for any guidance,

I have a a client for whom I am checking the general healthof their laptop.  Looking though the event log, I see a consistent series of the following event:

The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy18  (all 1-18 were flagged)

I have removed and re-established the pagefile, and this has not changed.

I've not seen anything else to better understand what may be at fault.

In addition, I noticed that for pretty bare-bones, one profile, and  no collections, and little more than MS Office installed that an inordinant amount of disk space was used (70 GB out of 225 GB).  From this, I used Space Sniffer to identify that the \windows\winsxs directory is 30GB!

I don't know whether these two conditions could be related.

Ian insight todetermine one or more root causes to either )or both) of these would be welcome.

Viao VGN-FW200, 4 GB RAM, Vista 64 bit Home Premium w/ SP2

Thanks!

For Vista Shadow Storage,  

Run  vssadmin list shadowstorage  to see what has been allotted.

Run vssadmin resize shadowstorage /for=c: /on=c: /maxsize=15Gb to resize it.

Resizing it to 1Gb will normally delete the shadow storage and you can then reset it.

This may clear your error.

So, did you run chkdsk or not (on the entire hard drive)?

Yes.  Chkdsk c: /R and nothing was noted as needing repair...  I did not scan the repair partition d:

And full scan with Malwarebytes, also with nothing noted.

Sorry I neglected to mention.

Thanks!

Sorry. Suggest a reinstall.  Save your data first.

Also 30 Gb is about twice as large as I would normally see. I don't know if this is related to shadow storage, but delete your shadow storage as I suggested and see.

Make sure all Vista updates are complete and not pending.

Thanks aadih

I'm considering an OS upgrade in place to Windows 7 (the client has a spare license).  I'm thinking this will correct any OS-related issues.  Do you concur?

Thx

Yes. Good idea. But I'd prefer a clean install, after saving your data, however.

Vista has been orphaned and so if you cannot fix it by my suggestions above and go for a rebuild, then by all means move to Windows 7 instead. Seven is vastly better and more useable than Vista.

Hi Thinkpads_User

I agree about the usability of Win7 vs Vista.  However, I hadn't seen your initial posts prior to my post suggesting a move to Win 7.  That said...

I followed your recommended actions to resize the shadowstorage, and

a) the shadowstorage was set to 30gb, and...
b) that size does correspond to the winsxs directory size.

So, now the ntfs error no longer is generated and the system size is more reasonable.

Also, another error I assumed was not associated was corrected.  So icing on the cake!

Thanks for the great guidance!
