Problems mounting Hitachi 7k3000 HDD in Voyager Q dock via eSATA

I have two NewerTech Voyager Q- Quad Interface SATA 2.5" & 3.5" Drive Docks http://eshop.macsales.com/item/NewerTech/FWU3ES2HDK/ from OWC.com that are advertised as compatible with 3TB SATA III Hitachi drives. I am using one as a main data drive, and the other as a Carbon Copy Cloner back-up. Today I had both of them running off my Sonnet Tempo SATA Pro Expresscard 34 on my MacBook Pro, doing a CCC back up sync. I went out and when I came back the cloning had frozen. I couldn't quit anything or eject anything, and several other apps became unresponsive so I had to do a hard shutdown. Upon reboot, Disk Utility wouldn't mount either of the drives, and they both failed verify/repair and also a rebuild in Disk Genius. So I tried plugging them in via FW800, only one of the drives mounted (the closest on the daisy-chain) and Disk Utility said it appeared to be OK. The 2nd drive wouldn't mount. I am quite concerned about this as I have a lot of data on there that I cannot afford to lose. Has anyone had any experience using the Hitachi 3TB drives in external eSATA or FW800 docks or enclosures? Any opinions on the Voyager Q docks?

Welcome to the Apple discussions.
You've done some good, thorough troubleshooting.
First blush I'm thinking the hard drive isn't working, until you start it via firewire from another volume, and you see flakey results, and can't complete a boot from DVD. That would support a failing logic board.
The Apple store can send your Powerbook to the Apple Depot for repair. We recently did this, system was sent to the Apple Depot in Houston, and cost was around $325. At the Depot, they repair everything, returning it in operating order. In our case they replaced the logic board and battery. If the case is banged up or extensive replacements are required, the charge goes up from $325. Comes back with a 90 day warranty.
If you're good with computer internals, you can buy a used logic board and replace it yourself. Good instructions at http://www.ifixit.com/Guide/Repair/PowerBook-G4-Aluminum-12-Inch-1-1-5-GHz-Logic -Board/553/1

New problems mounting an old external drive!

I have a 3TB external hitachi drive that has worked great. I have it formatted as MacOS extended Journaled. I haven't used it for quite a while I plugged it in today and I get a popup box:
The disk you inserted was not readable by this computer.
I initialize it and first of all - the imac only reads it as 801.57GB disc.
I cannot repair or verify the disk as I get this message:
Error: Partition map check failed because no slices were found
I'm kind of freaking out because I have 3TB of data on this drive that I'd like access to.
Any ideas how I can get my partition/data back?
***EDIT: I have multiple 3TB drives and all of them now seem to be affected by whatever is going on. I haven't used any of them in like the past month... Not sure what's going on.
***EDIT 2: SO I think I understand a bit more what's going on but not how to fix it. I have an external that has both esata and USB2.0 ports. Today, when trying to hook up the drive to my imac I was using USB 2.0. Usually however, I connect the drive to my imac via esata using a
Sonnet - Echo ExpressCard/34 Thunderbolt Adapter
I just tried using that and now the drives mount OK. Should I contact sonnet about this issue or can someone tell me when my 3TB drives would mount ok using esata and this adapter but not through USB 2.0. - Maybe I'm ejecting them incorrectly?

I am having a similar issue. I use an external Aluratek dock to connect my 3 tb barracuda drive to my Mac Pro using eSATA but when I try to connect that same 3 tb drive to my laptop via USB, it asks me to initialize the disk. It is unreadable. This is a serious problem and I think the issue is with Apple's OS as I have tried connecting the same drive via another portable USB dock and had the same problem.

Hitachi external HDD losing connection

Hi,
I have a problem with a Macbook running 10.6.8 and a Hitachi external HDD. The HDD has its own power supply. It is partitoned into 2 1TB partitions, one for Time machine and one for data.
It works as it should for a day or so then the Macbook seems to lose the connection to the drive. I have tried both USB ports on the Macbook with same result.
HDD works fine on a 2009 iMac running 10.8.2 !! The Macbook is running from mains power too, not battery.
Any ideas?

You might try resetting the SMC and pram
Laptops with a battery you can remove
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Raid Drives: Hitachi 7k3000 Deskstar vs Seagate Barracuda XT

Hi Guys
Thought I'd start a new post for this. Have got all my components sorted for my new pc and that is being built, but I needed to source my raid controller and drives from a different source. So here's the dilema.
Im going to be using an ARC-1880i SAS/SATA 6gbit 8-Port Card and was going to get 3 x Hitachi 7k3000, but they're not in stock and the guy had recommended the Seagate Barracuda XT SATA 300
Just before I take the plunge are there any advantages to using the Hitachis that I'm unaware of , or is the Seagate OK.
On the Raid side of things, still a bit unsure as to whether to use Raid 3 or Raid 5 . Am I right in thinking most people use raid 5? Just wondering.
Thanks
Nick
P.S Just found out that the Hitachi are very hard to find because of manufacturing after the Eartquake in Japan.

Unless I'm missing something, current Barracuda XTs are SATA600, not 300. Or did you mean the non-XT Barracudas?
http://www.seagate.com/www/en-us/products/internal-storage/
Price wise, the smallest XT is 2TB, and prices at $140
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148506
Same sized Hitachi's are $120
http://www.newegg.com/Product/Product.aspx?Item=N82E16822145473
But if you are going for speed more the capacity, I'd go with the Hitachi's 1.5TG at $65 each
http://www.newegg.com/Product/Product.aspx?Item=N82E16822145520
You'll get a much less expensive solution, especially in the long run when you'll add more drives to your RAID. At $65, you'll be able to have more disks, and be a lot faster.
If total capacity is not as critical as speed, ask them if they can get the 1.5TB Hitachi model instead of the 2TB.
PS: The Hitachi's have been tested on the Areca.
Most people use RAID5 because most RAID controlers out there are RAID5s. Only Areca makes RAID3 cards. Loosely explained, the advantage of RAID3 over RAID5 is the efficiency at reading and writing large files (video files) in a single user environment. Perfect for video editors. Also, if a drive fails, the RAID3 performance is not deteriorated. RAID 3 sucks in a multi user file server environment. Multiple access from different tasks bogs down the troughput drasitically. RAID5 on the other hand is way more efficient at reading multiple small files at the "same" time (documents, database access, etc). There is a good performance drop iwhen a drive fails, but it's still able to respond adequatly in a file server environment.
Many say RAID3 is an old inneficient technology and that it's dead. And RAID5 has evolved and is better at everything. Truth is, there is no one solution that does everything well. In reality, each has their place, and it depends largely on your workflow. So I suggest that, when your system is ready, if you have the time, try testing your RAID in both levels, and benchmark it yourself.

Backups failing with error 19: the backup disk could not be resolved, or there was a problem mounting it

Hello all,
Doubt this issue relates to a recent and ugly issue but sharing anyways (resolved thanks to a user here: LaPastenague)
Time Capsule won't backup if Modem (Motorola SB6121) attached
This was on Feb 10th resolved. Few days later I upgraded to Yosemite. Backups were working fine since.
Yesterday I happen to notice my last backup was 5 days ago. I looked in the console logs and saw:
2/25/15 3:55:06.127 PM com.apple.backupd[2777]: Attempting to mount network destination URL: afp://Paul;AUTH=SRP@Time%20Capsule._afpovertcp._tcp.local./Data

I called Apple. Their front line was clueless. He suggested resetting the TC (latest "tower" model btw") which then a backup kicked off YEAH
But the next hour it failed
Called Apple again, this time to Sr Advisor. He suggested factory reset of the TC and set up again. Also first backup worked then rest failed
Third call to Apple useless also. He was asking questions I didn't feel relevant. He also was asking me to reset the TC which I told him was done 2 hours prior. He asked me to reboot which I could NOT at that time.
I begged him to collect data to submit to engineering, which will take days to get a reply.
So I thought I would throw this out to the community....
TC Is NEW (replaced from last issue). Mac is 8 months old (iMac 27"), Os is Yosemite, TC also new (latest model)
Thanks...

Yosemite is problematic on two fronts.. Networking and Time Machine.. so the combo of doing both with a Time Capsule is like bugs on bugs.
Here is my standard list.. but your problem maybe difficult to resolve.. and my suggestion is simple.. until Apple get their act together and fix TM.. buy Carbon Copy Cloner and use that for your backup. It is solid and reliable.. even better if you use USB drive plugged into the computer and do a bootable clone.. because then you have a backup that is able to be tested for full functionality 2min after the end of the backup.
This also starts from a factory reset.. but the reason for it is to change the configuration which is much more easily handled with factory reset to begin.. the instructions are there.. because this is my standard reply.. this is not uncommon!!
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
ie Start from a factory reset. No files are lost on the hard disk doing this.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 and TCwifi for basestation and wireless respectively.
Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the Mac itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. What I list here is good network practice changes but I have avoided Yosemites bug heaven.
This user has had success and a few others as well.

Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

My Mac won't mount my external HDD after installing Lion - What can I do?

My Mac won't mount my external HDD after installing Lion - What can I do?
HDD: Verbatim 3.5'' External HDD eSATA & USB 2.0 #48802
I can not find it in Disc Utilities - so I can not repair it.
I also haven't found any Driver for the HDD to do an update.
My Mac is running on the most recent updates of OS Lion.
The HDD worked before. It contains my former Time-Mashine Backups. I would like to use this drive again. It isn't very old yet.
It would be much appreciated if anyone could help.
Cheers,
Yves

OK, try restarting in Safe Mode and if that doesn't work try resetting the SMC and PRAM.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

I am going to close this thread because (a) the thread is more than two years old, abd (b) may or may not be related to your problem.
Please open a new thread detailing your problem. Define what is "Solved" by rebooting. Does the drive mount during a reboot? Tell us how you are trying to mount the drive, and provide us your /etc/fstab. You may want to share the the output of sudo fdisk -l /dev/sda
If you still think it relevant. provide a link back to this thread.

Firewire Problems : Mounting iPod Using External HD - iBook G4?

I cannot get my iPod to mount on the iBook's desktop. iBook is a 1.33Ghz G4.
I have a 1st generation iPod and bought an external Seagate HD (160GB) and a drive enclosure (the latter included an external powerblock, I can post the make/model if needed). I bought the HD in with the intention of storing my iTunes music library.
I've never had a problem mounting the iPod on the iBook via the Firewire port. Using the external HD is a different story. Because the iBook has only a single Firewire port, I connect the external HD to the iBook's Firewire Port and then connect the iPod to the Firewire port on the back of the external HD. When in this configuration, the iPod fails to mount on the desktop.
I've done a temporary, barebones workaround by copying a few critical music files onto my iBook's HD iTune library and then just downloading those few files to the iPod. But this is a huge PITA. My iPod is pretty much crippled if I cannot load the music files I need on it. I'm frozen out of my music library. My iPod only is only 5gig capacity & will not store my entire music library, so I need to have the flexibility to load the music I want, when I want.
Can any one advise what, if anything can be done to get the iPod to mount while connected to the external HD?
Thanks a bunch for any assistance.

Anyone?

How to mount second ntfs HDD?

I have two HDD in my PC, one for operating systems and the other for all the large files which is formatted with NTFS (for Windows compatibility). I already have ntfs-3g installed and can mount my other operating system partition, but I have no clue how to mount my second HDD in my PC.

Assuming you only have these 2 drives hooked up (no external drives etc), your second drive is likely /dev/sdb. You can get a partition list by doing as root:
fdisk -l /dev/sdb
Then run ntfs-3g /dev/sdbX where X is the partition number you want to mount.

You are still under warranty and/or have AppleCare. Call them. Let them deal w/it.

Problems with seagate external hdd

I have a Seagate 3TB external HDD attached to my iMac via a Firewire 800 cable. I have the latest software running (Yosemite 10.10.3) but the Mac no longer shows the HDD in finder, I can see it in disk utility but when i come to verify or repair the disk i get this message
" Error: Partition map check failed because no slices were found" I also get this message:
Verifying volume “Seagate External Drive”Verifying file system.Checking Journaled HFS Plus volume.Invalid B-tree node sizeThe volume Seagate External Drive could not be verified completely.File system check exit code is 8.Error: This disk needs to be repaired. Click Repair Disk.
The drive is nearly full and I really don't want to lose any files, can anyone help please..

Hi Brian
Connect the External HD directly up to one of the iMac's and follow the Formatting and Partitioning instructions in Ken's article: (but note that doing so will erase the data on the drive)
Ken Stone's article: http://www.kenstone.net/fcphomepage/partitioningtiger.html
It's sounding more like your trouble is with network sharing than format, if so have a look

Anybody having problems mounting G-Raid 4TB eSATA after Lion install?

I have a G-Technology 4TB G-Raid connected to my Mac Pro via eSATA which has been working fine until I updated to Lion. Now it doesn't even mount on startup. Anybody else having this issue?

I tried re-intalling the silicone image 3124 & 3132... which I had originally installed in 2009 (was that Leopard?)
no luck! I could give you some details, but still the eSATA drives are not showing up. Incidentally, they are not RAIDed together, they are just four individual drives in a collective case.
Does anyone know specifically what drivers will work with eSATA in a LION (10.7) system? It's gotta be one driver, right? It's not a different driver for every manufacturer, is it? I hope not!

External HDD via eSATA or internal HDD - which is fastest?

I am thinking of putting a fifth HDD in the optical bay of my mac pro. It looks a little bit fiddly to install (brackets, routing cables etc). I also have a Sonnet Tempo E4P SATA card. Is aan external HDD connected vis eSATA as fast as an internal drive?
Also, if I have two external drives set up as RAID 0 and use these as a scratch disk for photoshop will they be faster than a single internal HDD?

I also have a Sonnet Tempo E4P SATA card. Is aan external HDD connected via eSATA as fast as an internal drive?
Yes - an external HD configured with the E4P is just as fast as an internally mounted hard disk. The advantage provided by the eSATA host adapter is that the HD attached to it is now hot swappable. The internal hard disk is not.
Hot swap is great for backup sets and adding storage as needed.
