#DRIVEDX SD CARDS SERIAL#

If this error is shown, you should have a close look at the footage as there may be some corrupted frames (e.g.

Lexar uses ID# 195 “Hardware_ECC_Recovered”. If the card produces a write error, SanDisks will log it under Attribute ID# 171 (shown as “Program Fail Count” in Drive DX). The issue is more often a number of uncorrectable errors, which the controller preemptively flags as EOL. I haven’t seen one CFast card that went EOL because the Total LBAs Written (attribute ID#241) got anywhere near the 3k write cycles. Lexar does not output a single value, so there is a formula, based on Total LBAs written and some other values I cannot present. SanDisk uses Attribute ID#230 (shown as Percentage Total P/E Count in DriveDX) to show the computed “age” of a card. If a card is reported as EOL, we simply forward a flag that is issued by the controller on the card.

MLC memory should be good for around 3000+ write cycles. If you keep track of the SMART report changes for every card, you should be able to see problems early on, but it’s additional work. This section contains a few values that you can check regularly. Look for a section that says “DRIVE HEALTH INDICATORS” or “Vendor Specific SMART Attributes with Thresholds”. Depending on the tool, the SMART report will have a slightly different structure. There are a number of tools with GUI or without – like DriveDX and smartmontools, which I'll use as examples in this post – to read this SMART report from the card.

The SMART report can give you some valuable information on a card, starting from Model, Firmware version, and serial number, to health indicators. If you work with CFast 2.0 cards, chances are, you already had a look at the so-called S.M.A.R.T.
