Nanoflash Card formatting Procdure at DVinfo.net

Lance Librandi · June 2nd, 2011, 04:58 AM

Hello,
I am having interment dropout problems with one or more of my 64gb cards to the point that I can not trust them for the fear of the problem occurring in a crucial area.
When the Nanoflash formats compact flash cards are bad data blocks locked out in the same way as HDU lock out bad data sectors?
The other option is that the cards are ok and the Nanoflash is the problem?
What the best way to check this out.
I would appreciate some help.

Many thanks

Hello Lance,

To answer your Question, Yes it is possible to get bad or corrupt sectors on a Compact Flash card, similar to what you would see on a hard drive.

This is not very common, but we have seen this in the past.

I would suggest Purchasing KLIX ($19.95) we have been working with them, on a testing function that will identify if the card has "bad sectors" Theoretically the Sequential test should fail the "bad cards", but in our internal tests we have found certain cards to fail intermittently.

Hi Andy will KLIX test and verify a card for data Integrity, from the information I have seen on KLIX it's a recovery program not a testing program?

Hello Lance,

Yes they have added this functionality, but have not updated their website to reflect the new feature, but once downloaded you will see that there is a testing function and under preferences you can set the parameters for the test.

In theory it should be able to identify the problematic cards, In our lab this has worked well in the past, but also keep in mind that various cards may "fail" in different ways, so this may take some tweaking, so that It can identify all types of failures. since we have had a limited number of "failure" cards with our internal testing.

Best Regards
