Meant to add that after you Disconnect, you will need to Reconnect again to display your delete options.
If still having trouble, try pulling the power from the TC and restarting as your description indicates that something may be running in the background. So far, I can't duplicate your issue, but I'll keep poking around.
Sorry, I cannot duplicate the "bands in use" message, so I don't know if the following suggestions will help or not. You may have already tried this, so apologies in advance if that is the case.
Try resetting Time Machine as follows:
Hard Drive > Library > Preferences. Delete the "com.Apple.TimeMachine.plist file"
and restart your computer.
Open System Preferences and click on Time Machine to set up Time Machine again, but for now only set up the computer that has the sparsebundle file you wish to delete. You can set up other computers later.
See if the reset will allow you to access your Time Capsule and the sparsebundle file you want to delete. Once you locate the sparsebundle file to be deleted, click it to highlight it (but do not open the file). Then try the gear icon above to see if that will now allow you to delete the sparsebundle file.
The sparsebundle format uses many small files, instead of one very large file, to more efficiently manage disk capacity. Each of these files, or "bands", is 8 MB in size; a large disk image will have thousands of bands. "Bands in use" implies that files are either being actively backed up at the time or the Time Capsule is rearranging things by deleting the oldest backups to make room for new backups.
How to stop the process? I don't know. At this point, I think I would call Apple support for assistance. I suspect some files are corrupted and hope that the "fix" is not erasing the disk and reformatting.
I called Apple support twice. The second time we went to a Terminal command to remove the sparsebundle. It appears to be working (it's a big file). I'll be back if there is a sequel to this saga.
A much simpler way of doing this is to get a program called "Trash It!" its freeware, and it has yet to fail me. Any time a program won't delete, simply drag it on the Trash It! program icon, you're prompted for your password, and it's as good as gone...
Having mostly the same problem. A sparse bundle on the time capsule that I need to delete to try and get time machine working.
sudo -rf NAME
OFBUNDLE
yields
rm: NAME
OFBUNDLE//bands: invalid argument
rm: NAME
OFBUNDLE/: Directory not empty
I'm very puzzled by this. I removed the corresponding .ID file in the same directory as the bundle. The computer whose time machine backup this was now has TimeMachine off with no disk selected and is off.
Is the command Apple is using any different?
I cannot get that bands file to disappear, even after cd'ing into the sparse bundle directory itself.
Any other suggestions on how to delete this thing?
First time it seemed like it worked, but then the Finder crashed and I had to relaunch it and the system. Same here, bands is always in use. Disconnecting users makes no difference. Restarting my Mac makes no difference. Restarting Time Capsule made no difference. So I copied what I cared about from the disk and just quick erased it and redid backs from all computers in the house. Was not worth spending more time on. The images should delete even if corrupted, perhaps a bug that can be fixed soon?
I figured it out. Basically you need to go into terminal. Then do the following:
ls /Volumes
(you will see your volumes listed)
cd /Volumes/(Time Capsule Volumename)
(this will Change Directory to the Time Capsule)
ls
(this will list the files on the root directory of your Time Capsule)
rm -r (filename.sparsebundle)
(this will delete the sparsebundle and all subdirectories and files underneath it)
