I have XP Pro SP3. I use Acronis True image to back up C & F drives (2partition nain HD) to a removable caddy mounted Hard drive which turns on and off with a lock key. I also have a multi purpose floppy drive / card reader to (mostly) read SD photo cards. I last used these devices about a week ago, but now the card reader bit of the floppy drive does not recognise SD cards and the Caddy mounted SATA drive does not switch on when I turn the key. No yellow warnings showing in device manager. Any ideas?
woodchip. No. The SATA drive is in a removable caddy in a drive bay and acts just like an internal SATA second drive. The SD card reader is a multi reader combined with the internal floppy drive. No USB hub. Maybe a physical problem ? I have a second card reader which is in my Canon Multi purpose Device so can use that for now.
