In 20912 I purchased a Raspberry Pi B and a 4GB SD card from RS. I have a couple of Pis (Pi's ?) and both have 8GB Patriot LX series. [...] Anyone know of a usb/disk test program like the memtest86 program?
In some (most?) cases the SD stack does not expose direct MTD access, only block access via an FTL. AFAICT that means neither linux nor userland can do any kind of meaningful test of the SD card, short of destruct testing. For "real" disks, you can talk SMART to the disk controller & ask it to run self tests &c. I've never seen an SD stack talk SMART, but I guess I never really looked.
