Outlook started acting up, so as part of my attempts to fix it I tried to copy the PST to another location. The copy failed part way through with a cyclic redundancy check error. How can I get past this and back up my data?
A cyclic redundancy check, or “CRC” error, indicates a bad spot on your hard drive. The fact that you see it when trying to copy a file indicates the bad spot may be within the file itself.
We need to verify that, try to recover your file, and repair your hard drive.
Hi, Leo. I have a sticky situation here. My daughter accidentally overwrote a written document and lost 60 pages of her story. We’ve tried recovery tools, such as Recuva and Undelete. She may have recovered some of it, but she’s unable to open it. It’s a Word Perfect 12 document and when we try to open it, it says it’s an “unsupported format.” We cannot understand how it was saved or recovered in a different format. Just to let you know we have it still. I’ve tried emailing it as an attachment to different people who are better at computers and no one so far has been able to open it.
Your situation is actually not that uncommon.
These days, file formats are complex and the programs that read them are often unforgiving when there’s something wrong with the file.
When only portions of a file are recovered, some of the information that the application relies on to open and interpret the file is so badly damaged that the application can’t even recognize the file to open it.
Typically, that happens when the first few pieces of the file are missing. But it actually can happen if any piece of the file is missing, out of order, or just otherwise unrecoverable.
