Hi Ronni, Partition Map Scheme is "Master Boot Record" Should I change that to "GUID Partition Table" ? And if so how can I do that ?
PS: What a nuisance having to eject the drive each time I turn off the Mac (which is very night before bed). But if that is the only way then I shall do that ! I might have to re-institute the Time Capsule without using the WiFi on it. I now have a new WiFi network from the new Telstra Modem Router On 18/08/2013, at 1:57 PM, Ronda Brown <ro...@mac.com> wrote: > Hi Stephen, > > Check your Time Machine backup that it has been backing up all data, and that > no files have been damaged by unmounting and disconnecting incorrectly. > > My comments below. > Sent from Ronni's iPad4 > > On 18/08/2013, at 11:55 AM, Stephen Chape <chap...@bigpond.com> wrote: > >> Thank you Ronni, >> >> Drive Model is WDBBEPOO10BBK-01 >> I have formatted as Mac OS Extended Journalled (not sure about GUID >> Partition Table) > > Have your WD My Passport connected, Open Disk Utility, select the WD Drive > (NOT the drive's volume which is under the WD Drive name)...
