I have an A-Data brand 16 gig SDHC card which became corrupted/damaged in my Canon S90 (it looks like a lot of people are having problems with this card). When I put the card into the card reader attached to my Mac Pro, the volume does not show up on the desktop, or appear at all under Disk Utility. No error message of any kind pops up. If I look in Console, I see the following messages: Code: USBF: 28693.905 AppleUSBUHCI[0x11f5b000]::Found a transaction which hasn't moved in 5 seconds on bus 0x1d, timing out! (Addr: 0, EP: 0) USBF: 28696.637 [0x12238100] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of Hub at 0x1d000000) USBF: 28696.637 [0x12238100] The IOUSBFamily was not able to enumerate a device. USBMSC Identifier (non-unique): 000000009451 0x5e3 0x723 0x9451 USBF: 28719.906 AppleUSBEHCI[0x1208e800]::Found a transaction past the completion deadline on bus 0xfd, timing out! (Addr: 5, EP: 1) USBF: 28725.906 AppleUSBEHCI[0x1208e800]::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 5, EP: 0) The last two continue to repeat. I have tried a variety of card recovery programs on my Mac, and on the Windows side booted under VMWare. But since the card is not mounting at all, none of these programs can see the card to try to recover anything. Does anybody have any suggestions? I really would like to recover these photos.
