Re: 1G Microdrive problems

[Andre Hedrick]

Check to see of your drive has meta-data cache.
This is a solution to reduce power consumption in portable devices.
You may have problems with some inital data but some of the things which
these devices do is voodoo.

Also one set of images could be put to platter as memory and not disk.
