Thanks for the suggestion, but it won't respond when I try to change from read only.
As far as losing all data during reformat, won't it be a problem because Time Machine will not work as designed, (i.e. not be able to go back to a specific date)?
Are you logged into your account as an 'administrator' and did you click on the 'closed' padlock icon in order to 'open' it (with your admin account password) ?
If you reformat and start a new Time Machine backup you will lose older versions of files that have been edited but the new backup will create a copy of all the files (with a few exceptions) on your computer.
Part of the problem here I believe (and I will stand corrected by the experts if I have this wrong) is in peoples expectations of Time Machine. Generally TM initially creates one copy of a file on your HD on the destination drive. If, over a period of time, you edit that file, TM will create a copy of the changes, each dated, which allows you to go back in time and restore an earlier version. But only the current version exists on your computer (unless you are using the newer versions of Pages, Numbers, Text Editor etc which maintain automatic versioning but that is a whole other complex issue), so the earler versions stored in the TB backup are not really 'backups', in the sense that they are the only versions that exist. TM has archived the versions, but only temporarily, because it may need to delete them at some time in the future to reclaim space (although I believe TM will warn you when it is about to delete a file).
One has to ask the question..."If these versions are important to us, what the **** are we doing allowing only one version to exist?" My take on the Time Machine is to consider it a backup of everything that currently exists on my computer. If an older version of something is important to me I make sure a file of that version exists on my computer (or on a external HD which can be included in the TM umbrella) which will then be backed up by TM (and other backup routines), so I will always have at least two, probably three copies.
Another question worth considering is.. "What if your TM destination drive died suddenly, without warning?" (they do) Then all those earlier versions would be gone instantly anyway. There would be no discussion about 'Will I lose this? or 'Will I lose that? So a good backup strategy is important.
Still, I hope you can salvage your TM drive, so please let me know if you have any success.
