change read speed of SD-card / recover (hardware related) damaged SD-card
Hi,
I have an SD-card, which isn't readable anymore. Tried 2 winows PC and one Linux. On Linux the card get's at least recognized as mmcblk0, causing lots of error messages in /var/log/messages like buffer I/O error. The messages stopped after lots of screens full of errors. Then I tried to read it via 'dd' but that just stopped with copying 0 bytes. fdisk can't access the card.
I had the idea that maybe it'd be readable with reduced speed, since it must be a hardware problem. Is there any entry in /sys where I can change the read speed of an SD-card-reader?
