SBS 2003, how to modify disk volumes

sagetechit used Ask the Experts™
Hi all,

We have a SBS 2003 server, which of course does about everything for us.  When the old IT guy set up this server he only gave the C: (OS) a 25 GB partition.  Well this drive has been slowly filling up and now only has 520 MB free space prompting warnings.  I need to extend this partition by 25 more GB.  There is one physical disk, a RAID 5 array, with two virtual drives the C: and D:, the D: has over 630 of 718 GB free, I want to take 25 GB from the D: and assign it to the C:, is this possible? and how? and the safest way to do to avoid data loss/system crash, as this highly important server.

Or any ideas of what files I can delete from a typical SBS OS drive to free up space, already gotten rid of old users documents and settings.

Attached is screen shot of disk management.

25Gb is more than enough for drive c:, rather than looking at making c: bigger, you should be looking at moving stuff to other more apppropriate locations - see LeeW's excellent article

Fisrt and foremost I would make sure I had a good working backup. This is critical. I would look to make sure that stuff like exchange, user data, pagefile and sharepoint were not all on the C:\ partition. If they are move them in order to free space that way first. If all of those are already stored on a secondry drive I would look at software such as acronis in order to make the drive bigger, but do so with extreme caution and make sure your backup is in working order.
As KCTs mentioned 25Gb is more than sufficient some server come with only a 12Gb partition. You can also delete temporary files in those \temp folders.

If you insist to increase the c:\ drive, I have used BootIT NG (BootIt Next Generation) before and it works as a treat. It is free as well. But for ALL partition tools there is a danger of corrupting the hard disks hence files, so the golden rule is to ensure you have a GOOD backup - double check it before you resize the drives.
Acronis in Gartner 2019 MQ for datacenter backup

It is an honor to be featured in Gartner 2019 Magic Quadrant for Datacenter Backup and Recovery Solutions. Gartner’s MQ sets a high standard and earning a place on their grid is a great affirmation that Acronis is delivering on our mission to protect all data, apps, and systems.

Most likely, you have log files and SQL database files filling up your C: drive.  By default, Exchange and MS-SQL server put C: drive as the repository for all data, backup, and log files.

Changing the locations of the data, backup, log files are less disruptive than altering the partitioning of the physical volume.  Changing the partitions could take _many_ hours, and may result in loss of data.  Only attempt if you have multiple backups that have been fully tested....and if you have an entire weekend as a maintenance window.

I started a maintenance window for an SBS2003 server on a Friday afternoon at 4pm...after a major failure that required restore and manual intervention by Microsoft support to mount an Exchange store...we weren't up again until Monday at noon.  Not fun.

If you can, get a good SBS admin to assist in relocating the data.  Most times, it won't require a re-boot at all.  Just a shutdown of the affected services, moving the data, pointing to the new location, then start the services.

If your exchange info store is on the C: drive move it to a new folder onto the D: drive.


Found some log files that where propogating.  Looked like the logs for mobile Excahnge connections, looked like RPc over HTTP, Active Sync, and OWA.  Deleted the logs from 2009 freed up close to 15 GB.


REmoved many log files from :


Looks like it was making a log of all OWA activity from each day, like Active Sync, RPC over HTTP and OWA.
