Error Copying PST to an External Drive

Outlook Inbox Repair Tool is a built-in utility for repairing and correcting .pst file corruption issues. But it can fail, for reasons, such as high extent of corruption or oversized PST. At this point, you should consider to opt for reliable and efficient solutions for PST recovery. These tools are found to be more powerful than Scan pst at repair.

To exemplify, consider the following practical scenario:

1) You try copy few files to an external drive including Outlook.pst. You notice that all files, except Outlook.pst cannot be copied and you receive CRC errors, after which the process halts

2) You rename the file and try to run Inbox Repair Tool to achieve recovery. But, Inbox Repair Tool fails too and you come across an error message as below:

“An unexpected error prevented access to this file. Use ScanDisk to check the disk for errors, and then try using the Inbox Repair tool again”

The file cannot be repaired even by using disk repair utilities, as suggested.


CRC errors are general symptoms of .pst file corruption. Scanpst is unable to solve the existing issue because of following reasons:

1) Outlook.pst is badly damaged. The Inbox Repair Tool generally fails to fix PST corruption if it roots from reasons, external to normal disk errors or application errors.

2) Your .pst file is ANSI formatted and is more than 2 GB in size. Outlook Scanpst.exe cannot repair the file if it is over 2 GB.


To solve the existing problem, you should consider these steps:

1) You should try to run PST Crop Tool first to reduce the overall size of the file. It is a Microsoft tool designed to crop the .pst file to fall under 2 GB. It deletes the email messages. You can then try to run Inbox Repair Tool.

2) If the problem persists, you should delete the damaged .pst file and restore it from a backup. If in case no suitable backup is present, you need to repair the damaged file using a powerful third-party .pst file repair utility. These software can fix PST corruption even when Scan pst fails.
