Have same problem with MacDrive. Trying to take files off a drobo that was mac formatted.
MacDrive sees the drive just fine. But transfer off it is a labour intensive 10MBps.
PC is a new one with win 7 pro. The drive I am transferring to is a seagate 7200 3TB internally installed on SATA – and was bought new in Feb 2013.
I have changed the firewire driver to the legacy version – got a minimal increase from 7 – 8 MBps to the 10.
Then changed to the ubicore driver – and no difference.
I tried transmac – and once installed it could recognise the drobo as a disk – but could not connect to it – stating “disk access error” so never got it to work.
I am waiting for the folk at mediafour support to respond again – having responded once to recognise my request, the immediate was to ask if I had tried and alternative connection.
Yes – tried firewire and usb – same result.
