My external HDDs can't be recognized on any device (PC or PS3). They were working fine this morning but now PS3 simply doesn't show them and PC says it's malfunctioning and it can't be recognized. I use ATA/SATA cables to use it as external HDD. I bought new ones to be sure it's not problem in cable connection. I tried using Disk Management but still no difference. I can't update driver, and after uninstalling it and updating using Slim Drivers it is still not able to function properly.
