OS X :: Unable To Format External Hard Drive / Starts And Stops With Disk Error
Mar 24, 2009
I received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?
The hard drive is a 1TB Western Digital my book I bought it in January I think. I tried to format it to Mac OS Extended (Journaled) when I got it but for some reason every time I try to erase the part thats named disk3s2 or partition the main one it stops a little before half way through. I don't think its the hard drives fault so I called apple about it one day and they helped a little but it didn't work. Thanks in advance if you can help me. Also a few times I waited about seven hours for it while I was at school and when I came home it didn't move.
I bought a WD My Book Essential to do Time Machine backups. It is formatted for a PC but I was told I need to format for my IMac before I can use it. How do I do that? Is it a complicated process? I have only been using a Mac for about a year now and am still learning about them.
i have just bought and external hard drive and want to put stuff on it. i know i hav to format it somehow using disk utility on my imac. what do i format it to so i can use it on both mac and pc? it is set to read only in "get info" and ms-dos fat in disk utility.
I'm running Snow Leopard on my new Macbook Pro. I've got a 1.5TB External hard drive that I'm trying to figure out how to format in HFS+ with Apple Partition Map. I can figure out how to format in HFS using Disk Utility, however it still does it in GUID format and I do not know how to do it in Apple Partition Map.
Googleing this for hours has lead with all kinds of information on how to go to GUID FROM Apple Partition Map but not the other way around. I know GUID is the new hottness.. but this drive will be used exclusively to connect to my XBOX 360 and it supposedly only reads HFS+ when its formatted with Apple Partition Map. (I have tried it with Mac OS Extended (Journaled) with GUID, and the XBOX does NOT recognize it) I do not want to use Fat 32, (I know that that is the other major option) beacuse it limits file size.
When I attempt to verify or repair disk permissions the process starts and then stops. The following message appears in a drop down message box: First Aid failed. Disk Utility stopped verifying (repairing) on G4HD because the following error was encountered: no valid packages. My disk verifies in working order. I have used DU from the installer disk and obtained the same resulting error message. I have run Tech Tool Pro's optimization and maintenance sequences. I reinstalled Security Update 2008-003 PPC thinking it might have been the problem. This permissions verification/repair problem and a problem with my firewire external HD and iPod failing to mount started after I installed the security update. (I am not asking for help with the firewire drive problems here - that is for another forum) I am running 10.4.11 on a G4. I guess my next step is to reinstall 10.4.6, the version I bought
I have partitioned my external Hard drive into three different partitions, each of different formats. Two partitions for backing up my macbooks and one to copy to and from my windows PC. I would just like to know if in any way is it possible for me to be able to re-partition one of the partitions, without affecting my Time machine partitions, in case the need be in future.
I have an external multimedia disk currently formated in NTFS microsoft format. I'd like to be able to copy content to it from my Mac and a PC so I thought to format it in FAT 32. can anyone tell me if there is a size limit to FAT32. what are the major limitations of FAT 32 vs NTFS
I'm selling a hard drive that doesn't work when formatted for Mac so I need to sell it PC format. Will MS-DOS (FAT) work, and does it need to be set to Master Boot Record?
I have a PC I can test it on but I just want to now what to do before I try it out so I don't keep having to switch between computers.
I just brought a Western Digital 1TB USB drive for my Mac Pro. Now when I try and format it in Mac OSX journaled it keeps coming up in an error saying it can't be done, It will format as FAT32 but I need it to be Mac OSX formatted. Does anyone know what might be wrong?
I just bought a new WD Elements (1tb) and I am getting an error when I try and format. I wish I could tell you what that error says but I was trying to figure something else out so I chose the disk6s1 and formatted it to os extended but it seems like it is frozen. I am afraid if I force quit it will screw up the drive. This is the 2nd one I have tried, I returned the 1st one thinking the drive was faulty. Now I think I screwed up the drive when I formatted it in disk utility. I have installed 2 western digital internal Hard Drives into my Pro and have used 2 other external HDs both western digitals. If there was any problems with any of my HDs, I would open up Disk Utility and Erase them to be Mac OS Extended (My WD TV won't read Journaled drives).
I am having issues with formatting my main drive in my Macbook Pro (mid 2009) to install Leopard.
I have booted off of several Leopard and Snow Leopard install discs and attempted to use Disk Utility to format my drive. Everytime I try to format the drive I get one of two errors: 1. input/output error OR 2. Unable to allocate memory.
I am going to be buying an external hard drive soon (Seagate FreeAgent Go 250GB 2.5" External Hard Drive - Black) and I want to double format Or double partition it. I am pretty good with macs, I just don't know much about time machine and external hard drives. What I want to do is either:
A) Make a partition in which I can make backups, and make a separate partition in which I can store files B) Make a single partition in which I can save back ups (from time machine) and my files (Music, Movies, Applications)
Also, would I be able to run Windows (XP) from my external hard drive somehow? Also, could I run mac applications off my external hard drive, is there a certain procedure?
I bought a new 1TB external hard drive. What formats should I choose in Disk Utility to make this disc compatible with both Mac and Windows? I rarely have files over 2GB and my Mac is running on Snow Leopard.
Verbatim Store 'n' Go USB 2.0 Portable Hard Drive 500Gb
this is a external hard drive i am looking to buy,but it has Nero back it up and burn software already on it,so in order for me to use it on my macbook,would i need to format it?
I've download a Seagate Diagnostics programme to check whether my external Seagate FreeAgent Desk is working properly or not. However, when I run the programme, it indicates that cannot find the disk.
Alright, so My ipod is formatted for windows when formatted in this you can only copy chunks of 4 gig things using it as an external. but if you change the formatt of it to take all sizes, then it's not compatible with mac and pc. =/ i had it originally formatted for pc because i just recently got a mac book pro and it's my primary computer. well on to the hard drive trouble that is related i'm borrowing my friends external to get a 8 gig file from my pc to my mac. it's formatted in fat32(windows and mac read) but that format only allows for a 4 gig max to be put on it at one time. so i guess i'm outta luck there, i've looked at JR split but who knows it that will work. My main q is, i'm going to be getting my own personal external soon and i want to know whats the best way to format it that it will mount on my pc and my mac and allow me to copy more that 4 gigs of stuff on it at a time.
I have bought an external hard drive (Fujitsu) recently and turned into an Mac OS Extended (Journaled) format. I was wondering can it be formatted on the same lines as an iPod. I mean like the iPod that can be detected as an external hard drive by both Windows & Mac. Can't I do the same for my external hard drive?
I used my external hard rive for installing linux(ubuntu) in my other machine. Now when I use the hard rive in mac os or windows, it does not respond very well. When I use windows for transferring files, it shows 1Mbps transfer rate. But it used to have 25 Mbps transfer rate in windows. Now when i use this drive in my mac, it does not show anything. I then used disk utility to reformat it to Mac os x extended journaled, it just gets stuck in Mounting..... like forever. Is there any way to reformat it Fully (i mean "fully" to remove the core files and rebuilding the system files for my external hard drive)) by using 'terminal' or disk utility? Is the hard rive hardware damaged(but the file transfers in windows though slowly? My external hard rive details are:
1.WD external
2.USB 2.0
3.size: 1TB
Info: MacBook Pro (15-inch Late 2011), OS X Mavericks (10.9.4)
i'd like to format my lacie external hard drive with two partitions:
1. HFS+ partition as a bootable clone of my internal drive
2. FAT32 partition readable by any windows (and mac) machine
i'm creating my partitions with disk utility, but i hit a snag when choosing a partition scheme...apparently i cannot choose a different scheme for each partition.
so when i format the drive with GUID, the FAT32 partition is not even recognized by windows XP. but when i format the drive with master boot record (MBR), the HFS+ partition is not bootable...
I can't manage to format my Seagate 500GB external HD correctly so it can be readable with my Macbook. I formatted like six times already in Windows 7 and XP to NTFS and still my macbook won't read it...only my Windows computers can read/write it. What am I doing wrong?
I have a Western Digital 500gb external hard drive, with 2 partitions, 'KAINARC' and 'JUNGLEMAC', connected to my Intelmac (Tiger 10.4.11 via my firewire, i have connected via usb but the problem is still the same). I may have shut down the drive improperly to cause this situation.
KAINARC now appears on my desktop, but the partition of JUNGLEMAC does not. I go to disk utility and both partitions are visable, KAINARC is mounted but JUNGLEMAC is not. I cannot mount JUNGLEMAC.
When i try to verify and repair the partition I get the message:
Verify and Repair disk �JUNGLEMAC� Error: The underlying task reported failure on exit
1 non HFS volume checked 1 volume could not be repaired because of an error
So I try to verify and repair the partition KAINARC but get this message:
Verify and Repair disk �KAINARC� Repairing disk failed with error Could not unmount disk
So I have opened diskwarrior (unbelievably long time to start up and scan disks) in the hope of fixing the hard drive, but when i try to repair I get the error message 'unable to unmount KAINARC'.
I have tried other repair/recover programs but get the same message: 'Could not unmount disk KAINARC'. Im asuming that to fix the hard drive it has to be able to unmount KAINARC.
got a real basic question to ask and you're gonna think im an idiot for asking...I just bought a 320gb western digital elements hard drive and want to reformat it so that its compatible for both mac and pc's. i intend to format it as NTFS-3G as it would allow me to use it on the 2 platforms without having the 4GB file size restriction that fat32 has, anyway.....
when I go to reformat my external hard drive in disk utility, I see my external hard drive to the left, and there's a "sub" hard drive as a child of the external hd listed uppermost. just wandering which one of the two do i select before going to Erase>Windows NT filesystem (NTFS-3G)>erase? Do I select the uppermost drive and erase that or the lower one? or both
