Re: [tlug] Micro-SD Card Throws Me A Curve Ball

[Dave M G <martin@example.com>]

Godwin,

Thank you for replying.

Following the information you gave, I've discovered that both cards have 
the "sdd: sdd1" designation. I guess that means that both are treated 
like a hard disk, and not like a superdisk.

Looking up on the net, I've discovered that the default format for SD 
cards formatted on the Palm Pilot is FAT16. But I don't know what file 
format it is on the micro-SD card (or if the format makes a difference).

I've included the dmesg output from both cards below.

Ironically, the micro-SD card that works also gave me some errors this 
time, which you can see here. Some I/O request errors. However, despite 
these errors, I'm able to browse the contents of the card and move 
contents on and off.

(First inserted the working micro-SD card)
