Hello, I am using Sandisk Extreme-IV 4 GB CF card on my embedded system. The card is heavily written/erased, and so i am worried about it's health.
Any way to make some sort of diagnostics to detect if the card is about to fail. Something like:
- read/write/verify sectors
- determine state of wear leveling
- maybe more...?
I've read some CF spec and they say it is possible to get the number of times a CF sector has been written to. The spec says:
The IDE "Translate sector" command (87h) apparently allows the host a method of determining the exact number of times a user sector as been erased and programmed.
Is this command supported by sandisk extreme-IV CF ? I asked this on Sandisk forum and did not get any satisfactory reply.
Please help!
Rgds, Vinod
