Time Machine Entries Grayed Out

Do you mean the Timeline at the right of the TM interface?

Is a drive/partition that's not being backed-up selected in the sidebar of the Finder window?

If they're grayed-out, it means there are no backups from that day, for whatever drive/partition is selected.

It sounds like you started backing-up a drive or partition on March 5, but have backups of other drives/partitions before then.

Yes the "timeline" on the right of the Time Machine window.

I back up the whole iMac hard disk to Time Machine on a G Drive. Settings have been the same for a year or so. So it is a single partition (whole disk) which is backed up.

How full is your TM disk? Now it sounds like your backups prior to March 4 have been deleted.

To be sure, check via the Finder (look but don't change anything). On your TM disk should be a single folder named "Backups.backupdb" Inside it should be a folder with your computer name; inside that should be a folder for each backup, named with the date and time.

See what, if anything, is there prior to March 4.

Pondini,

There are backups in the Time Machine folder from 3-13-2009 to 02-09-2009. Then there is a folder named latest.

Now for the weird part. Since opening in Finder. Now I can access all entries in Time Machine back to 2-9-2009.

Also opened mail to check. It is fine now too.

Thanks for your help. Maybe Time Machine just need a good "kick in its pants!!!" by opening Finder.

That is weird, indeed. TM does something new and strange every day, I think.

Glad it's fixed -- wish I could take credit for it!

Wow. Funny. Same thing happened to me, after my backup disk's directory got corrupted, and after successfully fixing it with disk warrior, all my time machine dates were greyed out and useless. Following what you did, I opened with Finder, and everything came back to normal... !
