Disk Error: Cyclic Redundancy Check

[Guest Tau_Ceti_2]

Hi all,

 

I have stored all my media files (.avi) on a single 500GB Western Digital

USB drive.

When backing it up to an identical 500GB USB drive, I got this error:

"Error: Cyclic Redundancy Check"

 

It seems to be affecting several files within the same folder.

 

I have 2 questions:

 

1) Even if I erase and then reformat this drive (erasing it wish DiskWipe

for example) can I still trust this drive to store all my media in the

future?

 

2) How do I know whether or not it is a physical problem with the drive, or

if it is just the files that are corrupted?

Run a complete CHKDSK on the drive.

 

Run WD Diagnostics on the drive. However, I am not sure how well WD Diags will work on a WD

drive on a USB converted drive.

Answer 1) I would not

Answer 2) It is a physical problem with the drive which causes the file

error. CRC errors are hardware related.

 

You can try David's advice, but I would not be surprised at more bad blocks

showing up. Many drives have a large

surplus of available blocks for bad block replacement. You should never see

such a message until all of the spare

blocks have been used.

Thanks David and Jim.

 

Jim's comment sounds serious. I didn't realize that a drive had to use up

it's quota reserve of bad blocks before a message like that appears.

 

Too bad... I wonder if the error or fail rate is higher with external USB

drives?

 

The drive is only about 6 months old, but it runs everyday, for a couple of

hours per day, playing video files (avi).

No. The same drives are used internally that are used in external

enclosures. The drive controller is in firmware in the enclosure. The

drives themselves are the same.

Sorry for your loss. I concur with Jim. Junk it (literally, don't give it

to someone else). It's a low level error. Is your power supply clean? Did

you abuse the drive? Sad that this has happened with such a reputed brand.

You could try getting an internal drive+ a good enclosure. People do this

because internal HDs typically have MUCH better warranties ~5 years. I am

also of the opinion that these are of better quality (I did read Colin's

post) than external HDs.

Errr, given you can buy an "internal drive" and put it in an external

enclosure,

I can't s see how that suddenly reduces the quality of the drive.

 

I expect warranties are less for the pre assembled external drive because of

the nature of their use.

 

They would tend to get knocked a lot and potentially handled very roughly.

 

If you get a SMART capable utility like HD Tune or SpeedFan you can see if

any bad sectors have developed under the Reallocated Sector Count attribute.

 

Bad sectors do happen from time to time, it's a fact of life. I always run

chkdsk /r over a new drive to see if any bad sectors exist before using it.

Re: Disk Error: Cyclic Redundancy Check

 

The discussion was about the difference in quality between an internal HD

and a retail external HD. No one talked about the quality 'suddenly

reducing'.
