OS X V10.7 Lion :: "MediaKit Reports Block Size Error" When Formatting Drive?
Jun 12, 2012
I got a new 2TB hard drive, and I'm trying to format it as HFS+ journaled case sensitive encrypted, each time I try I get the following error: "MediaKit reports block size error, usually caused by not being a multiple of 512." This is a brand new drive, it has a GUID partition map with one partition, that was created by Disk Utility, and the disk passed a full hardware scan from Drive Genius. Normally when I get an error I can google it, but this particular error only gives me links to RAID problems, and I'm not doing anything with RAID. What determines the block size? I did not get an option to set it anywhere that I could see. How do I fix this error and get my drive encrypted?

I've got a 2 drive 640GB Black Caviar RAID that I want to set up as just an OS and apps boot drive.
I realize larger block sizes have more through put but waste disk space, and smaller sizes save space but are less efficient.
My user folder (mail, media, itunes, video, docs) will be on a separate drive.
(1) So how do apps and OS files load at boot time and runtime?
(2) If apps like CS4 are large apps does it not make sense to set 256K as the block size?
(3) Or does OSX use many small files thus needing a smaller block size?

Is it possible to change a block size? I have a RAID 0 partition dedicated to video capture. Having blocks larger than the default 4KB would benefit performance. Could not find any options in neither Disk Utility nor Terminal�s diskutil command.

Every time Safari or Firefox, or any other application crashes or I have to force it to quit, I get an error report and when I click to send it to Apple I get a message saying it failed and cannot send to Apple. Anyone know what's going on? I have a Macbook pro (15 inch, 2.53GHz, Mid 2009).Â
Oh, and my Safari is Version 5.0.6 (5533.22.3). Think it's time for an update?

My macbook pro has been acting weird for a week or so. I'll be on the internet and then it will randomly shut down safari or google chrome and send an error report message. This also just started happening with my iPhoto and iTunes as well. Sometimes my computer will just shut off completely and restart with a message saying there was a problem and it had to shut down. It seems like there is some bug or maybe a third party add on I need to get off?

I'm new to mac, have been using mine for only three months now, but couldn't help noticing a strange thing. When I go to Disk Utility or cmd+i on a selected partition, the size reported by OSX is incorrect. E.g. I have a 250GB disk, so I'm used to seeing 232GB as usable disk space, which is a totally normal thing. However, OSX tells me that my disk is actually 250GB. More advanced partition utilities (currently I'm using iPartition but suggestions are welcome) report the disk size correctly. So I began to doubt whether folder sizes are reported correctly or "scaled up" to match the size of the disk?
E.g. if I was an ignorant consumer and tried to put 250GB worth of data on the disk, it wouldn't fit as there is not enough physical capacity to accommodate it, is that right?
Is it the normal behaviour or I screwed something up in the system?

I have just recently deleted my Bootcamp partition in Disk Utilities, and now im trying to increase the partition size of my Macintosh HD drive. When i go to the partition map and try to increase the size. The same error always appears. "Could not modify partition map because filesystem verification failed" I have attached an Image of what my partition map looks like right now.

I currently am on an early 08 Macbook Pro 17". 2.4ghz with 4gb of RAM.
I've recently purchased a 32gb SDHC card. Trying to create a bootable emergency drive with os installed on it.
I plugged it into my Mac via usb adapter and it mounted fine. Was formatted as Fat-32. So went to disk utility and reformatted as 1 partition, GUID, Mac Os Extended (journaled), to make it a bootable disk for the os. When doing this it appeared to complete fine, but disappeared from my desktop. No longer showing up in finder. Still mounts in disk utility though. Tried different ports, rebooting, and reformatting,, with no resolve. Reformatted it back to Master Boot Record/ Ms Dos, and it mounts again fine in Finder. Can drag data to it with no issue.
Reformatted again as GUID and again it disappeared from Finder and desktop. This is where I'm confused...In Disk Util it completes the formatting and shows Map Scheme as GUID and journaled. The odd thing is that on the left where disks are mounted it shows the indented partition as disk3s2. Even though I've renamed it when formatting. It will maintain the name formatting back to Fat32, but not with GUID. Also if I try to repair disk it fails. " Disk Utility stopped repairing �disk3s2� because the following error was encountered:
Filesystem verify or repair failed."Does not fail doing repair as Fat32.
Figured I would just try to install Os anyways and booted to install disk. When booted to Os it did list the SD card as an optional drive, but had the exclamation point listed as not being in correct format. Instructs to reformat as GUID. Went to disk util and reformatted and it disapears from select a destination.
My questions are.. am I missing something technical about these cards and formating as GUID?
Why will this mount in Finder and also in the destination screen for install if its formatted as FAT32, but wont show up in either as GUID?
Why does it show disk3s2 similar to windows partitions, even though it was formatted as GUID and renamed?
Not sure if I'm having an actual hardware issue with card, or have to do something to modify this to be useable. Tried this on a newer iMac with same result.

I am trying to format a SDHC card on my MBP. I am trying to create a recovery SDHC disk for my MBP.
The disk is a Transcend 16gb (class 10).
I formatted to Mac OS Extended (Journaled) w/ a GUID Partition Table but after this, Disk Utility is now showing only 10.38 gb of usable space, but finder is showing me the full amount (15.79 gb). When I look in finder there are NO files or folders on the drive.
I tested trying to put more than 10.38 gb worth of files on the disk and was told there was not enough space. If I format the disk to anything other than Journaled, I get the full 15.79 gb. Has anyone ever experienced this before?

My 2011 21.5" iMac has a 1TB hard drive. In the Finder, it reports 238GB used, 744GB available. But, in Disk Utility and in DiskWave analyzer, it shows 460GB used. "About this Mac" reports 460GB used with 206GB of "backup" that is not there (not invisible files, not showing up in detail reports). When DiskWave reports 460GB used, the detailed list of files & apps only adds up to 238GB - a mystery in that it cannot show the extra "used" space, but only reports free space as 539GB thus not accounting for the remainder. How can I reconcile these differences?

I am trying to print reports from my school database software. I have tried 3 internet browsers, turned off all pop up blockers, and I still can't print to screen a report in a pdf. I am trying to isolate the problem. On my PC, just hold the control key and click preview to pull up the report. Is this a problem with adobe and Mac OS X.

I have received 2 Panic Attack reports in the past 24 hours the first was obvious with the little black window message appearing in the middle of my screen the system was idle at the time with several internet window open and a exel workbook. The second occured overnight when I came to my Mac this morning the screen was black i.e. appeared to be asleep as normal I hit a key and nothing happened, I checked the machine and noted that indicator lights on a USB drive I had connected and this copnfirmed the machine was still on, I had my own panic attack! I did the reboot by turning the off switch off, and then restarted a report was displayed indicating a Panic Attack had occured i.e.Â

The report is gibberish to me I wish they would provide a clear indication in these reports to help the non tecky gain some level of understanding as to what may be the problem, that was a mini rant!Â

I wasn't sure if it wouls be a bad idea if I wiped the interal hard drive while I'm booting from a recovery disk, then made a RAID 0 with the internal drive and my FW800 external drive. I'm nearing my max for the internal drive. I have a second FW400 drive backing up with Time Machine. I was hoping to just wipe, make the raid volume, and then restore from the Time Machine backup.Â
I guess even before that, my FW800 is not working in Lion. I reformatted while connected by USB, reset power management, and reset PRAM, but the firewire bus panics and takes out the Time Machine on FW400 as well. Is there a fix for this somewhere that I'm missing? I bought the FW800 drive for the above reason, only to run into a wall trying to make it work. I really don't want to do a RAID 0 with a USB connection.Â
I'm not going to try setting up the RAID 0 until I get the FW800 drive working reliably, but I was hoping to kill two birds with one stone.Â

I have a Mac OS X install on a hard drive which I've removed from my system due to installing a new SSD with a brand new install of OS X. I'd like to use the old 500GB drive as a storage/backup drive, but the file system/all my data is still intact on the drive. This could be useful as I want to keep all my data and would save me having to copy across to another drive, format the entire disk and then copy it all back.
I'm just a bit worried about what to do with the system files that were on there... can I just move all the files I want to keep out of the usual Mac home folders and then just delete all the system folders as if they were never there? Or do I have to re-format/re-partition to get the most out of the 'new' media drive?

I was having problems with the external drive where I store my Time Machine backups, so I tried plugging and unplugging the drive but could not mount the drive. I ran Disk Utility and tried to verify the disk, which told me the disk needed to be repaired. I tried to repair the disk only to get an error message that Disk Utility could not repair the disk and it needed to be reformatted. So I tried to erase the disk with Disk Utility only to get the error message "Volume erase failed: Media kit reports not enough space on this device for requested operation". I am not sure what else to try at this point and could not find any similar questions here. Â
The drive in question is a 3TB USB Seagate Backup + Desk Media, formatted as Mac OS Extended (Journaled). It's divided into two partitions, one of which (2.2 TB) holds only Time Machine backups of my desktop and laptop and the other of which (800GB) is formatted similarly with some files stored on it. I was able to verify and repair this other partition. I'm running Disk Utility 13 on an iMac (2.8 GHz Intel Core 2 Duo) running OSX 10.8.5Â ...

I tried to install Ubuntu 9.04 on 500 GB external drive and it will now no longer boot Ubuntu nor Mac. I need to know how to fix this. Things already tried:
*Backing up harddrive and installing Snow Leopard (10.5.4 is what it is)
*Deleting the external harddrive and reformatting it.
I want to be able to keep all my mac files. The file with a ? appears when the Ubuntu livecd is not in. (that is the only thing that boots).

I am having the biggest trouble with a usb drive.
A while ago i needed to format a usb drive to have a bootable linux image on it because a server at work didnt have a optical drive. So i had a big fight with my usb drive to make it bootable and at the end it all worked fine.
Anyway now i need the usb drive and i cant write to it because its read only and diskutil doesnt let me do anything to it...

I know Macs don't play nice with NTSF drive and I don't need to do anything with it, other then to plug in a new 1.5TB drive I have and convert it into NTSF so I can plug it into my server.
Anyway I can format it because Disk Utility only gives you Fat32

So my exact problem is that I usually use my Flash between my Mac and other PCs. And I just installed OSX Snow Leopard from my 8GB Kingston Flash. Now I know to use Disk Utility to reformat to MS-DOS (FAT) to be able to to use it between the to OSs again.
So I do that but PCs won't read it and ask me to reformat it again. I'd happily do that cuz I know as long as it's in FAT or FAT32 the two OSs will be able to read and write from each other. But the PC only recognizes 200 mb and when I do reformat it on the PC there are now 2 different Partitions. One being the PC's 200 mb in FAT and the other Mac's almost 8GB MS-DOS.
I've tried a few different things too. I've tried Partitioning the whole thing over again int MS-DOS after having erased everything. Which I see only causes the Flash drive to shrink from 8.01 GB to 7.80GB and still isn't readable by a PC.
Then I tried Erasing it to free space but PCs still don't recognize it and still ask me to reformat the 200mb is sees on the Flash.

I have a windows PC from work that I use at home and I connect to the Internet from the PC and all my other devices using Time Capsule. The PC connects to work on a work VPN but it also shows up on my Devices list on my MacBook. Is there a way to prevent the PC from connecting to the MacBook and to stop it showing up in Devices? I assume it's a OS issue but maybe it can be done in Time Capsule. Either way, I have no idea what to look for.Â
Here's why I want to do that. I have two external USB drives connected to my MacBook and they both keep staring and stopping at a minute or less interval. I finally realized that this only occurs when the PC is on and listed in Devices. So I'm pretty sure that the PC is doing something across the network that is causing the USB drives to spin up when they would otherwise be idle. I think it would fix the problem if I could prevent the PC from finding the MacBook.Â
