Help: Updating boot support partitions for the volume as required

My external backup usb hard disk (WD 1.5TB) suddenly could not be mounted on my macbook, so i started a disk repair in Disk Utility. And after it shows "The volume XXX appears to be OK" and then volume repair complete, it shows "updating boot support partitiions for the volume as required" and then stuck there until now (i mean, for a whole night!!). I don't know what to do, the fan is spinning very fast, but the process bar seems not to be moving. It shows estimated time: 2 min, but it never moved on. What shall I do at the moment? I can't just erase the disk, all of my information and data is on it. Thanks.

MACBOOK A1278, Mac OS X (10.5.6)

I assume that means you don't have a complete backup.


If you haven't already done so, force quit Disk Utility. Back up all the data on the drive, if you can get it to mount. Be sure to check that the USB cable is securely seated at both ends. If you can't get the drive to mount, either on that Mac or another one, then you're in a recovery situation. I can't help you much with that, because I always back up my data and I've never tried to recover a damaged volume. The first thing to try would be to remove the drive mechanism from the USB enclosure and install it in another enclosure or dock. That might be all it takes, if you're very lucky.


Otherwise, depending on the value of the data to you, you may want to consider sending the drive to a professional recovery service such as Drive Savers, which will be very expensive but gives you the best chance of success. If you prefer to do it yourself, some people have reported success with tools such as "Disk Warrior" or "Data Rescue." I have no idea whether those tools will work in this case.

I am hanging here in Disk Utility as well with the same "updating boot support partitions" message. I have Mac OS Format. Originally it was formatted on Snow Leopard. I updated to Lion. I tried accessing the drive on a different Mac with Snow Leopard and that's what I'm repairing it in. I could see the drive in disk utility in both macs but it wan't mounted. Now it's been doing this update for over an hour. Is it save to stop repair? Or should I close out disk utility? What is the best way to stop this loop and disconnect the hard drive? Can I do it without damaging my data? This is my backup and it holds all my iTunes and iPhoto files.

I finally just stopped the updating. Once it finally did stop I was able to use the hard drive again. It is now mounted, which appears to be the reason it dropped. As soon as it reappeared I backed up all my files. Now it is working again but I've ordered another hard drive to replace it. I have no idea if it will drop again or if replacing the hard drive with a new one is a better idea. It would be nice to know a permanent solution to this problem. I lost my hard drive connection (dismounted) sometime Monday morning. I reestablished a connection, remoounted and completed the back up by Tuesday morning. (I had to leave it overnight because it was at work.) Not quite a week later I have had no more symptoms of dropping my connection to the hard drive. I reordered the same WD 1TB drive because it works best with my MacBook for size and convenience as it is packed along with my MacBook everyday. I plan to backup with TIme Machine on a Network HD in the future. What's the best HD for quality and ease of use with Macs? Can you share a networked HD with a PC once it's set up for use with TIme Machine?

Apple goes all crazy with ease of use solutions that are in reality have many points of potential failure.


It's ok to experiment with these solutions as a secondary backups but not as one's only form of backup.


For example a network is prone to interference and compromise especially since most people don't know how to properly secure their network. TimeMachine is a complicated piece of software that introduces more complexity in the user backup experience, the drives TM creates are not bootable therefore offer no hardware protection.


For one's primary backup, the saying "keep it simple stupid" comes to play, a simple and highly effective hold the option key bootable clone, two in fact, rotated about two weeks apart and updated nightly if you have many daily changes. This allows one to be back up on their working computer with all their files and programs intact in the time it takes to boot.


The two software's of choice for this are Carbon Copy Cloner and SuperDuper, both have scheduling and updating ability so one isn't copying the whole boot partition all over again each time.


Also one should try to avoid using external Western Digital drives, especially the "green" ones that tend to self power down and don't lend themselves to operating correctly when access is needed.

Hello,


you said "keep it simple stupid" -- that IS the reason why most people use Time Machine there is nothing really to set up, it is built into the system. For that reason we trust that since it is made specifically FOR Mac that is is the best solution. I for one was not aware of the problems you mentioned.


Could you please explain exactly what you mean by "hold the option key bootable clone" ?

And why do you NOT want to copy "the whole boot partition all over again"

One last thing: if you recommend not using "external Western Digital drives ..." what do you recommend?


Thank you,


BTW - When I also have "and then volume repair complete, it shows "updating boot support partitiions for the volume as required" and then stuck there " on my main drive. What can I do?
