Ok, so "Whistler Wednesday" was a little bit too much to keep up with. So, we're going to go with "Whistler Wendy's Tips"
These may (or may not) come out each Wednesday
****So for today's tip:*****
Many of you have questions about Boot/Load times of the Whistler SD card scanners
At boot, the code looks through the entire File Allocation Table, counting “free” clusters.
This is necessary so that we know how much free space is available on the card at startup.
The number of clusters that must be counted is directly related to the size of the card.
As a result, a change in card capacity at a minimum will impact the “Init SD FileSys” time.
In addition to card size, the “Verifying Data” time is dependent on the usage of the card and is heavily dependent on file system fragmentation, used space, etc...
Happy Scanning!
