What To Do With a Corrupt Data File

Applies To: All Products
Date: 10 June 2004

If you have a corrupt data file there are a number of steps you can take to recover the information.

Step 1

Make a backup copy of the data file under another name. Keep this backup in a safe place and do not attempt to open it, compact it or repair it. You will need to use this file if you have to proceed to step 4 or step 5.

Step 2

Open another data file and select Compact and Repair Data File from the File Menu on the application's main menu. If after doing this you can open the data file within your MIE Software application the data file has been repaired.

Step 3

Copy the jetcomp.exe file from the MIE Software CD or download it by clicking here. The jetcomp.exe file is a utility program provided by Microsoft that can sometimes compact and repair data files that can not be compacted and repaired using the compact/repair function within Microsoft Access. Run jetcomp.exe to attempt to compact the data file.

If after doing this you can open the data file within your MIE Software application the data file has been repaired. You should then check your data carefully as the Compact/Repair process can truncate some tables that it can not interpret.

Step 4

If jetcomp.exe fails to compact the event file, you can zip and e-mail the data file as an attachment to your local distributor or MIE Software. MIE Software have utilities that can recover some types of corruption. There is a minimum charge of $143 (including GST in Australia) for this recovery service, but there is no charge if we are unable to recover the data file. The charge for the recovery service depends on the size of the corrupt data file and the number of corruptions. We will give you an estimate of the charge when we receive your file.

Step 5

If the file can not be repaired by MIE Software there are companies around the world specialising in recovery of corrupt databases. One company that has been used in the past by our clients with some success is PK Solutions. The web address of their rescue service is http://www.pksolutions.com/services.htm.
