Hardware :: AEBS - Which External Hard Disk To Get
Jan 12, 2010
I want to get an external hard drive for my Airport Extreme, in the range 1tb (maybe 1.5tb but likely 1tb). Google reveals some people have had problems with particular drives so I thought I would ask which drives work well so I can just avoid any problems in the first place?
I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state! Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.
Recently I purchased an external hard disk, to put all of my pictures of my baby due to space limitations on my internal laptop drive. Since my Canon camera 10 megapixel pictures take up a ton of space this was occurring at an alarming rate. My intention was also to back up to DVD but never got to it. This is both a comment and a question.
Now said baby, is getting really good at pulling cords etc. He managed to do this on the external drive firewire cable. As far as i know the drive was not in the process of actually writing. However, after a few minutes and trying to re-plug the drive the OS crashed with a Grey Screen of Death hardware error that tells you that you need to push the power button..
This apparently corrupted the drive's directory. Upon reboot the drive would not mount. Since there were time machine backups on the drive too Diskwarrior was not able to reconstruct the drive in the built in memory available on the computer. Time machine stores millions of files and Diskwarrior apparently wants to keep it all in memory at once. Since my computer has 2GB you would hope that would be enough but apparently not. So that failed. Other utilities seemed to be able to find the files but not restore the directory. I also took it to the apple store they were not able to recover it.
I have to say this is extremely distressing, and hard to believe that a simple accident like this could cost the loss of thousands of pictures. I did send it to a rescue company but that was expensive but I think apple needs to do something about this situation.
On Windows there is a way to disable the write cache for external drives. This is not available for Mac OS X. This would prevent this rather common occurrence of a plug accidentally becoming disengaged when the drive is not in the process of writing. This reduces the odds but I still think apple, in order to become clearly superior, needs a better solution.
I know Apple has experimented with ZFS would this not eliminate this possibility of this kind of disaster? Is this in Snow Leopard desktop? I know they are thinking this is a business customer focused technology but clearly if it can eliminate this kind of thing then I think it is extremely useful to their non server customers. Perhaps there are other ways of dealing with this issue but ZFS is designed to deal with these issues. HFS+ is extremely fragile to disk corruption.
I know my situation is not that uncommon and this is not the first time this has happened to me with an external drive. You would think I had learned. I hate to think of how many other people have had the same thing happen to them.
I have a Seagate 1 TB Backup Plus Drive which was working perfectly fine until I plugged it into a USB hub. It detected it while in the hub and I was able to get files off of it, but when I ejected it from the hub and put it back into the USB slot on the computer it was not detected by finder. It shows up in the disk utility and I clicked verify and repair and it says:
Verify and Repair volume “Seagate Backup Plus Drive” Checking file system Volume repair complete. Updating boot support partitions for the volume as required.
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
Is there any way to get this to work properly again? Or if not is there a way for me to recover my files on the external hard drive?
I have a Macbook PRO late 2011 running OS X Mavericks.
I have an external 500GB Freecom USB HDD with two Data partitions on it (FAT32 and NTFS). With a Windows tool, I made the two partitions smaller in order to free up some space (ca. 200GB) for an additional Mac OS Extended (Journaled) partition. This partition I wanted to create with the Mac OSX 10.6.4 Disk Utility. When I pluged in my USB HDD in my new iMac it mounted the two partitions, NTFS and EXT32 and the Disk Utility tool also showed the free (unpartitioned, almost 200GB) space on the HDD. Then, I chose to create a new Mac OS Extended (Journaled) partition and let the tool do it. ...which I probably shouldn't have done. Disk utility stopped and showed an error message saying that it cannot read the partitions anymore and that it needs to be closed. No partitions can be mounted anymore since then on this HDD. Here is the logfile entry of Disk Utility (unfortunately, it's in German):............
I just got a new harddisk and have been trying to get it functioning properly today, the problem is the following: Drive is partitioned in HFS+ using macdrive7 (installed on my system). It does show up in windows very easily thanks to the airport utility, however, it shows the file system as being fat32. I formatted the disk in HFS+ on purpose to be able to storage large files in the network drive, so this is a problem. Also, the disks show empty, although i already put some files on the disk for testing purposes, this was done when the drive was connected directly via usb. Does anyone know how I can get windows to show the drives as HFS+?
Since the AEBS firmware update I've been trying to access my usb-disk, connected to my Airport Extreme, through the internet using MobileMe, without success. My iMac and Powerbook show up in Finder under the 'Shared' tab but my airport-disk doesn't. Back to my Mac is giving a green light ... MobileMe registration in the Airport utility sticks and all settings seem to be OK. What's wrong?
ISP also provided a router (Philips) which is NAT and UPnP enabled ... AEBS is connected to the Philips with ethernet (Bridge Mode). Disk is HFS+ formatted ...
Anybody got the same problem? Anybody got a solution ...?
Since upgrading my MBP 13" to Snow Leopard, I'm having intermittent connection problems with my Airport Extreme Base Station (5ghz band) shared 2TB USB WD MyBook Studio drive. The connection appears in the finder sidebar but the main window header shows "connecting..." and frequently does not connect. Resetting the router is only a temporary fix.
I've bought three over the last two years, and only one of them has lasted longer than 18 months. I think one of them may have been damaged in a fifteen hour flight, but it still works (albeit too slow to the point that it's unusuable.) My .5 TB monster just died last week, which had almost all of my video files from the last year, totaling 300 GB in data loss. What can I do to avoid such situations? Should I maybe get a 1 TB disk for everyday use to replace my .5 TB disk, then a 2.5 TB disk (or bigger) just for backups? What sort of backup software should I use? (not Time Machine, I'm not interested in backing up my entire computer several times, just my FCP files.) How long do external hard disks last for you?
My intention is to partition an external HD in half allowing it to serve as a backup for a pc running windows xp, and the other half as a backup for a mac(10.5. I am using a Seagate external HD(new) that was initially partitioned on a windows xp computer.
The 1st half of the 1TB HD was formatted in NTFS format, and the second half was erased and (I thought) reformatted in HFS plus but when I attempt to use CCC(Carbon Copy) to copy the mac 1/2 of the hard drive, I get this message:
"You may have difficulty booting from this target volume, the underlying disk is not formatted with a partitioning scheme that Apple recommends for Intel Macs."
I have read the recommendations that the external HD need to be partitioned with APM or GPT, but I cannot seem to get to that option now for the mac side of the external HD.
In the Disk Utility, the external HD shows both sections of the partitioned drive(the xp section and the leopard). I do not want to reformat the entire drive(both sections) if at all possible.
I just want the Mac side of the ext drive to be properly prepared for CCC, and the windows side to remain as is.
My external hard drive has been corrupted and the error message is telling me to reformat it. However, through all the research I have done to find out how, everything I've found has told me to use Disk Utility to just erase everything on the disk to do this. When I try to do this, it tells me that I can't erase anything because the disk cannot be unnmounted. What should I do?
I had a WD external hard disk which I was using on my pc but not any more since I'm not a PC user any more. However, I'm a mac user now but when I connected my WD external hard disk I found out that I have lost everything on it. I thought may be because of my mac so I connected on my PC again and i have not seen any file which means I lost everything. Give me any software on mac that will get everything that I have lost.
My Mac Pro [with 4 internal disks, 2 External Disks (Sata Raid 0), and several external FireWire disks and a Voyager disk station] has a little problem with letting externals go Since a few weeks I have a problem with unmounting my externals. After unmount, the unmounted disk will mount again immediately.No time to disconnect cables and/or power. Hinders disk management, backup, and simple disconnecting disks. It only happens with disks (FireWire 400/800/ SATA and USB alike). USB sticks work fine.
I recently acquired a MAC book Pro and this being my first APPLE product - I am still learning lots abt this notebook. My question pertains to using an external hard disk in the MAC book Pro. I have a transcend external hard drive that works on the mac book pro - without my having formatted it etc. It also works on a windows system. ( I have as yet only used it to access documents that were previosly stored in the external hard disk) Can I continue using the hard disk as -is or would I still need to format the disk to make it MAC book pro friendl

It's really important to me.
I'm using a macbook and would like to copy over several games over to my friend's external harddrive. The files are rather large -8gigs, 6gigs, 4gigs.
For some reason it wont allow me to copy the files to the HD. only prompting me with the message "the operation can't be completed because an unexpected error occurred (error code 0)".
I presume that it's formatted correctly because I was able to copy a smaller file (363megs) without any troubles. However, whenever it involves these large torrents it prompts me with that same message.
Is it possible to manually put an external hard disk to sleep? Right now, I've already got "Put the hard disks to sleep when possible" checkmarked in the Energy Saver preference pane, and so they should sleep after 10 minutes of inactivity, but I'm wondering if it's also possible to do this manually whenever I want.
I just bought an external hard drive and it's already spinning constantly, compared to my current external which is completely quiet, so I'm wondering if I can put it to sleep when I need to to stop it from spinning all the time.

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.
