I have three external hard drives. All are recognised by Bridge. In order to cope with my large collection of images I have installed a fourth - a 1Tb Fujitsu Storagebird. This is recognised by Photoshop CS4 (all updates applied) (but not if I try Browse in Bridge), by My Computer on Windows, by DxO Pro, even by by IrfanView. But Bridge plays fast and loose. I have, on occasion, managed to get it to recognise the drive, but generally I have to struggle, restarting the Fujitsu, refreshing View in Bridge. Today, however, it is completely refusing to recognise the drive.
Any ideas?
