How to recover data from a crashed drive.
Unable To Mount Drive For Repair Mac Os
In such a situation, the first thing to do is to look at the disk storage. Usually, unable to mount database (‘hr=0x80004005, ec=1108)' error appears when the disk storage is full. Now, if you have the database and logs on separate disks, you can check both the drives. If the drive of the database is full, you need to extend the storage or move the database to a larger drive. There is no possible way to compress the database as it is already in a compressed format.
This can cause may different issues, usually resulting in the PC sync being unable to perform properly or start at all. Follow the steps below to repair or reformat your SD card. Format your SD card.

In case, the log location is full then the culprit could either be an antivirus software which is interfering with the backup or the backups are not correctly backing up your Exchange Database and purging the databases. Another reason for the log files not being purged is that the backup software is not application aware or Exchange Server friendly. In this case, you must either move the log files to another location which has more storage space or increase the disk space if the server is a virtual machine.
If the database is still unable to mount, after increasing the space, you need to check whether the database is damaged or not. To do so, use the ESEUTIL tool.
By running the below command, you can identify the state of the database.
If the database is in Dirty Shutdown state, you might be in a bit of sticky situation as the database might be damaged or there could be a missing log file.
In such a case, you can use EseUtil to perform a soft recovery or a hard recovery. However, there is no guarantee that the database will mount afterwards.
First, you need to run the below command to identify the required logs,
Once you have the log number, usually it is like E00, you need to use the R parameter to initiate a soft recovery:
This will start the process of recovery. Depending on the size and damage to the database, the process will take some time. Once it's finished, you need to re-run Eseutil command with / MH parameter to check the database state. If the database state is healthy, you will be able to mount your database.
If the Dirty Shutdown state persists, you have two options:
- Restore the server from backup and loose all the data from the last backup
- Perform a hard recovery process
CAUTION: If you perform hard recovery, you need to accept the data loss as the process purges the damaged data, irrelevant of the amount. On the other hand, after you perform this process, Microsoft will not provide assistance. This is because when a database is recovered with the hard recovery, it will hard code some information. When this is noticed by Microsoft, it will refuse to provide support.
To perform the hard recovery, run the below command:
Once executed, you will be warned of data loss and you need to accept it before proceeding. This recovery must be used as a last resort.
Once done, you will get a screen like below.

You will need to run the EseUtil again with the MH parameter to see if the database state is healthy. If the database is healthy, you will be able to mount the database.
