AEBS won't see MacDrive formatted HFS+ drive

I'm trying to reformat a FAT32 drive to HFS+ with MacDrive. I only have an OS9 Mac which doesn't understand the drive (120GB) at all, so MacDrive on my Windows machine seems the only option (apart from getting a new Mac...).
However, formatted to HFS+ by MacDrive the drive can only be accessed, it seems, by MacDrive itself. The AEBS doesn't see it it all.
Has anyone ever succesfully created new HFS+ volumes with MacDrive that can actually be read by the AEBS? If not I probably have to wait until a friend comes over with his MBA...
By the way, I also tried making it HFS+ with GParted on my Linux machine with similar lack of success. So it begins to look like I need a real Mac to create an AEBS-compatible HFS+ drive.

I can't format it on the OS9 Mac because the machine doesn't even see the drive in either FAT32 or MacDrive formatted HFS+ state. To make sure the USB card was okay I tested that with a 1GB USB stick, which works fine and I can format that to HFS+ without problems. But when I connect the 120GB drive it doesn't show up. And as OS9 doesn't have any kind of USB drive utilities, there's little one can do at that point as an "erase disk" on a recognized drive is the only option.
The drive itself is fine. Every other machine (including the AEBS) sees it when it's in FAT32. But I want to convert it to HFS+ to be able to store files larger than 2GB.
The drive is self-powered by the way, so it's not a bus-power problem either.

  • Disk Utility won't let me format external drive to FAT32

    Maybe this cannot be done or the answer is simple and I am missing it. I have a 1.5tb Maxtor drive hooked up via fw800. I want to have 120gb of this as Mac OS extended journaled to back up my internal drive via Time Machine. I want the other 1.38tb to be in FAT32 so I can share files between my windows and mac machines. I keep all of my external storage except for the backup partition in FAT32. I have never had an issue until I upgrades to Leopard and now when I click on the larger partition I only have the option for the 4 mac formats-- FAT32 is not available. I can format the entire 1.5tb to FAT32 but once I try and partition it only mac formats are available. I forgot to mention I just did the upgrade to 10.5.1 and the issue is still present.
    How do I format the smaller partition as mac os extended journaled and the larger as FAT32? Any help is appreciated.
    Thanks so much,
    Patrick
    PS. I did a search but did not find anything.

    It may depend on the type of partition table scheme you are using (see bottom of page in disk utility for that says Apple Partition Map/APM, GUID Partition table/GPT or Master Boot Record/MBR partition map).
    MS-Windows can read MBR scheme only (64 bit MS-Windows supports GPT, according to MS). If you have Apple Partition Map, your disk won't be usable on Windows. I suspect you have APM partition table and hence the disk utility is not giving the option for FAT32 format, since you can't use it under MS-Windows.
    On the Mac side, all 3 schemes are readable (for bootability, you'll need APM on PPC Macs, GPT for Intel Macs). Time Machine doesn't need a bootable disk, but I'd suggest APM/GPT if you are using PPC/Intel macs respectively (but I'd think either will work for Time Machine, if you have a mix of Macs).
    But here's the catch - Apple says Time Machine won't work with drives with MBR partition map (even though Macs are MBR-aware), so the issue for you is Time Machine's ability to use MBR drives. http://docs.info.apple.com/article.html?artnum=306932
    I suspect unless you are on an Intel Macs (OS X) and use only 64 bit MS-Windows (using GPT)/Itanium, using the same disk for TM and FAT32 sharing between Mac and Win worlds is not possible. Not the desirable answer.
    If you do want to experiment, make a temporary setup and try it out on both Mac side and Windows side first (on all your machines), before making a "production" system. You can select the DISK (first line on Disk Utility for that disk, not second line) and click on Options at the left bottom (it might have to be erased first) and then select the type of partition scheme. Note formats like HFS+/FAT32 are a level lower in the hierarchy than partition map/table.
    Let us know what you find out/decide?

  • My iMac won't see my firewire hard drive

    I'm trying to connect an external hard drive to my iMac. It just doesn't see it- I've been using it fine on 2 other macs. Always the drives just appear but there is nothing. I've tried different cables, 400/800, but it's just not there. Help would be greatly appreciated. It appears fine via USB but it's way too slow a connection

    Hi - is the Firewire drive a Western Digital MyBook? That's what I have and have exactly the same problem. I've got a late 2009 iMac and the only way it'll connect and be seen is via USB. The drive will happily connect to my previous gen iMac, it just seems it won't talk to the 27 inch via Firewire.
    I did some searching on this 18 months ago and found others with the same problem so I've settled for USB. It does mean that via USB I can use it as a bootable clone if I have any problems with the 27" (I don't think the WD MyBook can boot via Firewire even if it could see the drive - could be wrong on this bit though ).

  • Wndr4700 media router formatting hfs internal hard drive

    Recently switched over to all macs in our house.  I was thinking about getting a Netgear Wmdr4700 instead of a time capsule.  The router utility can only format hard drives as ext4 which from what I've read is not read/write compatible with macs without additional software.  However the router supports and recognizes pre formatted  hfs+, or hfs+ journaled drives.  Any ideas on how I can format an internal hard drive with a Mac mini or MacBook Air before installing it in the router?  Mabye I'm missing something...

    Hello,
    here is some info to help you out.
    time machine will work perfectly fine with ext4 file system this is the default file system for the unit, i have have other netgear NAS devices with ext4 and btrfs and they also work fine with time machine. but if you so desire...
    to format the drive with HFS+ you would need to do this via USB sata enclosure attached to mac mini or macbook air they cost about $20-30 the other option is if you know anyone with older mac pro (tower) they could format if for you or take it a place that repairs computers and they should be able to do this in just a few mins if they have a mac around, makes sure you create only 1 partition, GUID and choose mac osx entended journaled. make sure the wndr4700 firmware is updated first...ver 1.0.0.52 is the latest...then add newly formatted HFS+ drive  turn back on and wait until unit shows green HD lights up on front. then follow instuctions to backup..my other advice is to buy an external 2.5 inch USB 3 drive as a secondary backup for your macs using time machine as well attaching it to your macs once a month (dont attach it to the netgear, even though you could), for backup...1 drive will work for several macs, buy according to size needed, backup once a month to this as well and then hide drive in your sock drawer, 2 backups are better than 1, good luck.
    once your backups are all done, upgrade all your MACs to mavericks for free!!!!

  • Mac won't see some files/folders on external hard drive that i know are there, pc sees them fine..

    I have a external drive full of music, my mac won't see all of it , its like some files are hidden...  I have formatted the drive to exFAT and copied folders I knew were missing and they won't read that way either... I have as well renamed the folder to something different, but the Mac still will not see them, but my PC sees them fine... anyone??

    Same problem here!!!

  • Time Machine won't erase a Hitachi 1T Drive (can't format it in DiskUtility

    Just got my copy of Leopard and attempted to use Time Machine. The external drive I have is 1T brand new and my MacPro does see the drive; DiskUtility won't let me format it as Mac Extended or Journaled despite the box the drive coming saying it would allow OS X compatibility. Time Machine launches, attempts to erase the drive and then gives an error. Dead stop. Suggestions?
    External Drive is Hitachi easy device 1T in size from BestBuy.

    If you attach a drive which is greater than 512GB in size and comes pre-formatted using the Master Boot Record (MBR) partition scheme then you will need to re-partition the drive using either the Apple Partition Map or GUID Partition Table partition scheme before it will be usable by Time Machine.
    To re-partition the drive, open Disk Utility, select the entire drive, select the Partition tab, select "1 partition", select the "Options" button, and then select either "Apple Partition Map" or "GUID Partition Table", click OK to dismiss the sheet, click "Apply" to repartition the drive. All existing data on the drive will be erased!

  • Mac Book Pro won't see my iTunes Library on an external drive

    I have a brand new Mac Book Pro and my iTunes Library is on an external drive.  My computer won't see this Library even if I change the location under Preferences.  All I can see are my purchases from the iTunes Store on my iCloud.  I don't want to clutter up my MBP with my iTunes Library so what should I do?
    I'm running Yosemite and latest iTunes
    Thanks for any help
    Les

    Really a library, or just media?  A library is a complete collection of files an folders including the critical iTunes Library.itl file, generally all enclosed in an "iTunes" folder.  You do not direct iTunes to open a library with preferences, you do it by holding down the option/alt key while starting iTunes and guiding it to the .itl file you wish it to use.

  • Boot Camp with Win 8 Can't See The USB External Drive [MBR with NTFS, Fat32, HFS Partitions]

    Hi. When I boot to Boot Camp with the latest Apple Windows Support drivers can't see my USB Flash Drive, DVD and OS X volumes but not my USB external drive that has an MBR partition scheme (using iPartition from GUID) and in there it has different volumes [HFS when I boot to Snow Leopard, Fat32, NTFS]. What can I do with Boot Camp to make it see my USB external drive and why isn't it seeing the USB when it can see the USB flash drive both use USB?
    Thank you in advance.
    God bless.

  • Formatting a drive in HFS (Mac OS Standard)?

    I pulled my old Mac, an older G4, out of storage to attempt to install Ubuntu linux on it. There seems to be something wrong with the CD drive (DVDs mount, but CDs don't), so installing from the CD is out. I was going to go with the hard drive install method, but here's the (latest) problem I've run into... the docs (https://help.ubuntu.com/6.10/ubuntu/installation-guide/powerpc/boot-drive-files. html) tell me the drive I'm installing from has to be formatted HFS, not HFS+. It doesn't seem that I even have the option to format either of the 2 internal drives as Mac OS Standard, only HFS+. Disk Utility also gives me the option of formatting it as "UNIX File System", but unless I'm misunderstanding something, that's not going to help me.
    Anyone have any thoughts? Are there any programs out there that'll format HFS for me?
    G5 1.6MHz    

    Hi, David -
    Did that machine originally come with OS 9? If so, boot to an OS 9 Install CD of appropriate version, and use OS 9's Drive Setup to format the drive as HFS.
    Note that if you need to be booted to that volume, you will need to install OS 9 onto it and boot using that - OSX can not use an HFS (Mac OS Standard) volume as a boot volume.
    If you do not need to be booted to an HFS volume, and you just need one from which to run the installer, then if you happen to have a Zip drive in that machine you could format a Zip disk as HFS, place the installer on it, and run it from there.

  • Airport utility won't see AEBS and I cannot setup

    I have a new AEBS dual band (MC340LL/A), and I have been trying to set it up. My current system is an Intel iMac (Leopard) and macbook pro(Snow Leopard) that has been using the Internet via an old Snow? airport (M8209LL/A).
    I have Airport Utility 5.51 installed, but I cannot get it to recognize the base station. The amber light flashes, but no recognition so I cannot set it up.
    I tried unplugging my old Airport and disabling the network, I tried connecting the new AEBS directly to the laptop via LAN, I tried a hard reset (I hope) many times, but it won't see the base station. Of course it sees no base station, and since I have the same Airport utility on both Macs, I cannot see either base station when I try to hook up both of them.
    The old base station is still working even though I cannot see it (hence this message), and I am not worried about it, beacuse I plan on retiring it, if I could ever get the new one set up.
    Please help. What am I doing wrong?

    "Bridge" is technically the more correct way to configure the AEBS as you only want one device....in this case the Linksys....handling DHCP and NAT service. You have two devices both doing this now. May or may not cause some issues down the line.
    If you connect the old Snow to your AEBS using an ethernet cable from a LAN port on the AEBS to the WAN port on the Snow, and configure the wireless network with exactly the same name, security and password as the AEBS, that will in effect extend the wireless signal, but only at b/g levels. The Snow must be configured as a bridge to do this.
    There may be some issues with security settings here. I don't remember much of anything about the Snow. I doubt that it has WPA2 Security capability, and that's probably what the new AEBS is using. May take some experimentation to see if you can match settings between the two devices.
    Glad that the factory reset did the trick and that you got things going

  • Suddenly Mac mini won't "see" external drives. Possible related to OS software update to 10.6.8?

    Suddenly Mac mini won't "see" external drives, neither Firewire nor USB. Possible related to OS software update to 10.6.8? Worked fine under 10.6.4. Any advice? Thanks.

    Turns out it was nothing to do with the OS update, it was just a loose cable plug connecting my FireWire/USB hub to the computer. But your tip is a good one -- I'd been wondering why the external drives (even when mounted properly) weren't showing up in the sidebar. Thanks!

  • Formatted HD and iPod won't see songs that I have reinstalled on HD

    I formatted my HD. I copied the library of the iPod back onto the computer into MyMusic. However my iPod won't see any of the songs that I recopied onto the computer. I was forced to reformat the iPod. My song library is in MyMusic the whole time but the iPod won't see any of it. How can I get my iPod to see the songs in MyMusic.

    " However my iPod won't see any of the songs that I recopied onto the computer"
    What exactly does that mean? The iPod is not supposed to "see" your music in your "My Music" folder.
    I don't get what you're saying, or what the issue actually is.

  • Imovie not seeing partitioned time machine drive. I partitioned my TM 2GB and formatted Mac OS Extended (Journalled). These drives in iMovie have a Yellow exclamation mark and I cant access events. Can access in Finder?

    Any assistance would be greatly appreciated

    Thank you for your response. I was able to successfully format the drives Extended journaled when they were out of the raid configuration. I was not able to format as Extended (not journaled) in the Raid configuration.

  • Why won't my newly formatted MS-DOS(Fat) Hard drive work on my windows computer?

    I just bought a Macbook Pro. I understood that to make my old hard drive work with the Mac, I needed to format it to MS-DOS(fat). I also understood that this format was supposed to allow it to work in windows as well. However, after formatting to MS-DOS(fat), my hard drive will no longer become visible on my windows laptop. It makes a noise when I plug it in or take it out, but nothing pops up, and while I am able to find my hard drive in the management section - I am unable to edit it in any way except for disabling it. I cannot access any files. This is problematic for me as the computers used at university are not Macsle
    Can anyone please help me?

    If I were you, I'd format the drive on the Windows side as NTFS. Then use the $20 Paragon NTFS software to be able to read and write to the volume.

  • E:\ Drive (CDROM) not shown in explorer - also won't see media in cd rom

    I have a Satellite C655D-S5200.   I have had difficulty getting my cdrom drive to:
    1)  show up in explorer (it doesn't)
    2)  read media that is inserted into CD
    I know a few things:
    I had this problem since one of the latest Updates from Microsoft (which one I don't know).   I have tried all the solutions thorugh Mr. FixIt on Microsoft.  I have tried dozens of possible solutions in the Toshiba Community Forums as well as other online tech support forums. 
    One forum posting I read I noticed the user booted into safe mode and was able to see his e:\ (cdrom drive) under computer in explorer.   He had determined that it had to be a recent update to one of the drivers on his system that was preventing the CDrom driver from working properly.
    I tried the same.  Booted into Safe Mode and viola!  I saw my E:\ drive (CDROM).  It also was able read media in the CD.
    This helped me rule out the issue was the physical hardware.   But I am still baffled as to what is interferring with the cdrom.sys driver for the TSSTcorp cd rom drive when I load windows 7 normally.
    Has any of the tech experts at Toshiba had this problem?  If so, maybe its time to update the cdrom.sys driver after finding out what other driver is conflicting with cdrom.sys and preventing the cdrom drive from being seen or able to read or even write media.
    Just as an fyi, I just recently purchased recovery cd for my particular serial numbered laptop.   I inserted the first recovery disk into the CDROM drive and followed the instructions.  the CDROM was able to see the CDrom drive, read from the CDrom drive and reinstall the factory image to my laptop.  
    once I completed the recovery, applied all the Microsoft updates, I rebooted and once again the cdrom drive (E:\) from my explorer disappeared and I can't even get Mr. FIxIT to see media in the drive.  
    Any ideas from either other users or the Toshiba Tech experts?   I am desperate.  I have to be able to access my CDrom drive and read and write to it.   but I can't go into safe mode everytime I want to do that (plus not all apps run in safe mode anyway).
    PLEASE HELP.... THIS IS the 4th (fourth) week I've been messing around with this issue.  I need a solution!!!!!!
