Good Grief!
I bought two of these little beauties in about 3 weeks ago to use as a mobile disk, and for back up reasons.
In this time both machines have corrupted data, and I have lost plenty of gigs. Luckily (being an untrusting sort of guy) I backed up all the data before relying totally on the icy.
I am so pleased to have found this link. I will now try the previous threads ideas on updating the firmware, but to be honest may just RMA the little bu*gers as they have caused me hours of annoyance.
I have a lacie d2 250gb external hard drive which has NEVER failed, running on a mac.
A search on google led me here, and I must say I am delighted to find that other people have the same problem as I had, its nice to know that the problem is nothing i am doing my end!
PS the version I had/have is the firewire/usb2 version, my problems have all occured through the firewire port.
Cheers guys
Tony
