I was transferring a 2 GB file from my desktop to an external hard drive. But I accidentally restarted the computer. Now I'm getting CRC errors, and I can't access what's on the hard drive. Windows 7 always says that I format the drive.

Is there a way I can fix this, using a free software. What do I do recover the data?

You can perform checkdisk on that drive or perform a low-level format.

  • If it is asking him to format, it is not showing him any partition, or drive letter. You can't run chkdsk with no letter.

I do not know if you can fix the disk, but depending on how valuable the data is, File Scavenger would recover it, but the version you would need is $49.

I would caution you to run a diagnostic on the drive before you do anything else. You may well have more than just CRC errors as they usually only come up on a bad drive. Contrary to what others say, CRC errors are unrecoverable. They are usually seen as a result of the internal logic of the drive giving different data for the same sectors and the check noticing this and throwing up an error.

Western Digital and Seagate both have software that can and will low level format your drive if it needs it. As long as you don't have a failed or failing drive, you should be able to recover your data or at least some of it provided you don't write very much to it.

Good luck because I think you are going to need it.

The only way to recover data from a hard disk having CRC errors is to recover data from platters directly, but this can be done by data recovery lab experts. Or sector-by-sector recovery by using hardware firmware tools.
