Western Digital Raptor Drives Unmounting

I put two Western Digital Raptor drives (74 gig) in my Mac Pro and they are recognized. I've formatted them and data is stored on them. I've run scans on them to ensure that they are healthy, disk checks indicate that there is no issues. HOWEVER, when I come out of sleep Mac OSX automatically unmounts both drive automatically. I can repro this every time. Apple support has no clue. Help.
Thanks,
Ryan

My 74GB Raptor does the same exact thing on my 8-core Mac Pro. I think it's a firmware issue with the drive and since Western Digital doesn't offer firmware updates on these drives, we are SOL.
It worked fine on my Dual 2.3GHZ G5. I talked to WD today and they said to put a jumper between 5 and 6 to make the drive compatible with SATA 2 logic boards but that did nothing. It still unmounts after waking up from sleep.
We just have to buy a newer Raptor. It's really frustrating to deal with this for "enterprise" products.

Western Digital External Drive unmounts when USB used

I have a Western Digital 1TB My Book Studio edition external HDD. Its been unmounting recently without warning. I fianlly narrowed it down to when I plug or unplug a USB device such as a headset.
The drive is running in FW as I dont have any spare USB ports. WD are now blaming the computer. After reading other issues people have had with WD I dont believe them. I'm about to install 10.5.8 but I doubt this will fix it, also the HDD has the latest firmware.
Has anyone else had this sort of problem or have any suggestions?

I have a Western Digital 500 GB My Book that mysteriously mounts or doesn't mount about 50% of the time. Am using it in FW, though I've also tried USB with no change in behavior.
The drive gets fiercely hot - I suspect this might be contributing to the bad behavior of the drive. If I check the System Profiler when the drive doesn't mount, it is showing in the System Profiler - but doesn't appear on my desktop.
Out-of-warrantee support is $50 - or I can throw it out and buy a different brand for about $100! Guess which one I will choose!

Can anyone verrify if the western digital raptor will work on my computer?

I need a new hard drive and I wanted to know if the western digital raptor works well in a dual 2.7GHz power pc g5.
here is a link to the hard drive

There were two versions of the 74 GB Raptor - the older one with an 8MB cache, and the newer one with the 16MB cache. The 16MB cache version is basically the same as the 150GB Raptor with one less platter inside.
My understanding of the Raptor compatibility is this:
If you have a G5 Quad, all Raptors will work with no problems (I have a 150GB Raptor as my boot drive in my Quad and have had zero issues).
If you have one of the other dual-core models besides the Quad, the Raptors seem to be pretty reliable, but some users have reported problems. Adding a third-party SATA controller card solves the problems.
If you have a pre-dual core machine, the 8MB cache 74GB Raptor will work fine. The 16MB cache models need a separate controller card to avoid issues.
Do a search for "Raptor" in this forum and you'll find some quite lenghty threads on the subject. Macgurus.com forums also have some good information. In addition, I'd check XLR8YourMac's Drive Compatibility Database for info. The main thing to look for is reports on the 16MB cache version, which is what you linked to.

Mac Mini conflict with Western Digital External Drive

My Mac Mini used to work fine with my 2 TB Western Digital external drive, but now when I plug it in my desktop goes blank and the drive won't mount. I have tried it both USB and Firewire. The drive DOES work with my Powerbook G4.
Any help is greatly appreciated.
Thanks

Hi-
Please clarify.
What mini are you using? One of the new 2009 models?
As for the drive, is this a Firewire 800 drive or a Firewire 400 connection?
If it is a firewire connection, are you daisy chained to another firewire device? If so, in what order is the hard disk?
If it is a firewire 400 connection, what adaptor/cable are you using?
For a USB 2.0 connection, are you connected to a hub, or directly to the mini? Is the hub powered or not? Have you tried a different USB port? Same results?
Did you plug in both the USB and Firewire cables at the same time?
What is the model of your WD ext drive?
When you say that your desktop goes "blank" what exactly do you mean? The computer is still on, but there is no image on the screen?
You mention that the drive works with your Powerbook G4. By Firewire? USB?

Macbook with retina display + 500GB western digital hard drive

I have just bought my macbook pro with retina display and I have a Western Digital hard drive that doesnt show up when I plug it in. How can I make this work?

Just an update:
I tried to boot by MacBook into safe mode with the external plugged into the USB port and could never get past the Apple Logo boot screen. I then detached and tried to boot up my MacBook regularly and still nothing.
So today i took my MacBook and WD External Hard Drive into the genius bar (they were super cool), turned out that my MacBook hard drive had dismounted itself so I had to wipe and reinstall (not a big deal, I had everything backed up).
Then they plugged the WD into different machines running 10.6.8, 10.7.1 and 10.7.3 and the External did the same thing with everyone of the machines, proving my intial theory wrong that it was my upgrade to 10.7.3 that caused this problem.
Didn't get a chance to try Paragon's NTFS driver and at this point I'm a little gun shy. The external is still under warranty so I'm going to see if WD will just swap it out for me. Anyways, thanks for the input.

Western digital hard drive worked fine on my pc. I connected it to my macbook and it began time capsule, but now I cannot see any of my files on either my mac or pc?

Hi there,
Thanks for the reply.
I plugged my usb hard drive in and what looked like time capsule started automatically on my mac. The same hard drive worked perfectly on my laptop pc before, now it connects but isn't visible in my computer.
My second hard drive works perfectly well on both my pc and mac, so I am not sure what has happened to the one in question.

Western Digital Hard Drive Firewire Issue

Hi all,
I just bought a Western Digital Hard Drive (My Book Home Edition) 1 TB. Thing is it works for USB 2.0 but my Imac won't recognize the drive when I plug it in a 400fw. I called western digital and tried the disk utility tricks, and still nothing. The 400 input on my computer is fine, so is the cable. In fact the computer worked fine with a 500 gb Lacie a few days ago.
Any thoughts,
Thanks>

First thing is try the steps in this article by Apple:

IMac G5 with OSX 10.5.8 does not recognize my Western Digital external drive containing the majority of my music library. Is there any way to access that drive and recover the music stored there?

I have an iMac G5 with OSX 10.5.8 that does not recognize my Western Digital external drive. I had no problems with this until I upgraded to 10.5. Most of my music library is stored on the external drive. Is there any way to access it to recover the music?

How is it connected? Have you tried different port? How about logging in as a different user then trying to mount the drive.

Portege M400: Can I install a Western Digital SATA drive?

Can I install a Western Digital SATA drive in my Portege M400?
I've tried and failed.
I can copy the system resore CD to the new HD but the result is a blue-screen failure when the system boots.
I can't get a clean install of Windows XP to even start -- the HD is not recognised despite using the Toshiba SATA/RAID drivers from a floppy.
I've tried using Norton Ghost to copy an image of the existing (working) HD to the new HD but that also results in a blue-screen failure.
Is there something proprietary about the SATA?
Will the laptop only work with the original HD?
Will a replacement (larger) Toshiba HD work?
-ne

Power down the notebook and start it pressed ESC key.
On the third bios page (pg down) you find the raid configuration.
I assume you actually have already the RAID setting but it is not really written to the HDD.
At first remove the RAID and change to JOBD the password confirmation 1234.
Save settings und reboot. Enter bios again and change it from JOBD to RAID (again 1234).
After this your HDD will work fine!

Which Western Digital 500GB drive?

I'm ready to buy an internal non-raid 500 GB SATA drive and I decided on the Western Digital brand. The only problem is that I see at least three model numbers for, what looks like, the same or similar drives. The model numbers are as follows:
WD5000KS
WD5000AAKS
WD5000KSRTL
The prices vary and the WD5000AAKS is the least expensive offered by ZipZoomFly for only $136.50.
Can anyone advise me on the differences (if any) between these models and which would be the preferred model to get for an Intel MacPro? Thanks.

My choice: Caviar SE16 WD5000KS
Found this from Google SilenPCreview forums
WD5000KS vs WD5000AAKS
I don't have any test equipment, but I do have a 5 KS's and 2 AAKS. All are at 128 AAM in rubber grommet mounting.
Subjectively:
The AAKS are only very slightly quieter than the KS's. They do have noticeably less vibration. Seek noise is the same on both. Spin up/ Spin down is quieter on the AAKS.
I usually go by StorageReview forums and reviews, and SilentPCReviews, as well as look to see if AMUG has anything to say. Also, check WDC Store
I buy direct from WDC (so I would get latest model) as well as ZZF and OWC.

HP Compaq nx6310 Doesn't Recognise Western Digital Hard Drive

Could someone please help me?
I have an HP Compaq nx6310 laptop with a corrupted 40Gb HDD. I decided it was best just to replace it.
I have purchased a Western Digital WD3200BEVT 320Gb HDD. I have the OEM OS disk which I also had to purchase from HP.
Nothing I do seems to work. The OS (WinXP Home Ed) goes through the install process, but when it tries to run for the first time it always comes up with a disk error.
I have read that HP laptops and WD drives don't get on that well. I understand that there might be some drivers somewhere, but I can't seem to find the right ones (at least the ones I'm using don't resolve the situation).
I'm really at my wits end, and am ready to try anything.
Thanks, Bill

Western Digital External Drive

I am planning to go to Best Buy tonight and pick up a Western Digital My Book Premium 320 GB external hd. Does anyone have any experience with this?
I have several video tapes I have been pulling into iMovie and am quickly using space on my iMac drive, plus I'd like to back up all my photos. Since I've never used an external drive, I'd like some feedback.
I've read about backing up and cloning, but I'm not sure I care about that. I'm really just concerned about 'archiving' my data, should anything happen to the computer. My applications and computer are replaceable. That being the case, do I need to partition (I've never done that and don't know how, so would need to be 'taught').
Also, I've read about backup programs, ie. Retrospect, and I believe the drive comes with one from Western Digital. If I understand how they work, they copy designated files to the external and then periodically compare with the internal, and if there are changes, back them up. What happens to the 'original' file. What I'm really wondering is...if I am getting this as an archive, so I can remove certain photos and videos to make space on my main drive, but still want access at some point, will the program see this as a change, and discard the original from my archive?
This is probably pretty basic, but I just want to understand what I'm doing before I start. Thanks!

If you use SuperDuper, which I wholeheartedly recommend, you can partition your new external drive (use Disk Utility to do this), and use one partition to clone your drive (automatic backups will reflect what's on your main drive, so if you delete media from it, it will be deleted from the backup as well), and the other partition to archive your photos and videos. The second partition will not be affected by any backing up you do with SD. I suggest getting a large firewire drive, so that you will have space to do both.
I have been using a LaCie Porsche drive for a couple of years and have had absolutely no issues with it.

Intel Mac Pro w/10.4.7 - I need to access a 2003 Western Digital hard drive

Hey another question for the gurus of Mac out there. Got an Intel Mac Pro running 10.4.7 and I need to access old information from someones else's Western Digital (internal/ external w/case) drive. It's a "WD1200JB-00RCA1" model drive from 2003. I've already tried using the case with firewire connection on both my laptop and Mac Pro, but it will not mount. I does get power though. I'm thinking of trying it internally, but know that the Mac Pro is picky about specific types and specs on drives. Just curious if anyone thinks I can make it work internaly without screwing up the drive or more importantly, the Mac Pro.
Apparently this same drive was used internally on a mac back in 2003, but obvioulsy an older Mac. Any tips appreciated.

That drive (according to WD) is a WD Caviar SE 120GB UDMA 100 IDE drive. Assuming everything is set-up correctly, external enclosures typically require the drive to be jumpered as and IDE master, then it should mount.
The fact that it doesn't mount is not a good sign.
You could try this internally in the spare optical drive bay - you'd need a 5.25" to 3.5" mounting kit. If I were to go this route, I'd disconnect the optical drive temporarily - the cables will reach better and you stand less chance of getting an IDE bus incompatability with the optical drive.
I think the default set-up for the MacPro IDE bus is Cable Select so you may need to look into jumpering the drive dor this (CSEL)

Western Digital External Drive and a VERY slow computer. Is my HD failing?

Hello, thank you for looking at my question.
First off, I am NOT very tech-savvy, but I'm willing to research and learn, I'm just afraid to make a mistake and blow up my computer.
I have had my Macbook for 2 years. I have not backed up my hard drive during that time. Bad, I know.
Recently I've noticed my Mac getting slow with the "spinning beach ball" showing up more often and everything getting slower. Usually a reboot will help. Yesterday, for the first time, the reboot took about 8-10 minutes! I figured that wasn't a good sign, so I headed down and picked up an external hard drive (Western Digital Essential model, 1TB) and figured I'd back everything up. I formatted the drive according to the Mac partition model (tech support from WD helped over the phone) and got it going. From 1530 to 0800 this morning, of 52 GB it had only backed up 15.3 GB. The fan was running at high speed the entire afternoon and night. That's about one GB per hour. Is that normal?? Then, it froze and wouldn't respond, or back up at all. Just nothing. I held the power button down and restarted it.
At this point, I am concerned that perhaps the hard drive is failing (hence the speed and fan issues) and that maybe I should be taking it in to a repair shop (we don't live anywhere near an Apple store)
Do you think this may be the case? Is there any way to back up my hard drive faster - before it dies? I have two years worth of photos and papers, etc on there, music and such and it would be a tremendous loss if it all crashed.

Good! Better to inquire than leap!

Yup.

No, not normal at all.

As slow as that backup was, anything else will be nearly as bad.
There are four common causes of this:
Your startup drive is nearly full (less than a couple of GBs of free space). If that's the case, find something big you can "archive" to CD/DVD or copy to the external HD and delete.
The drive is failing.
Corrupted directores, etc., in the file system
One or more "runaway" processes, usually from incompletely-installed or partially-deleted apps
|
It's a toss-up; try to diagnose what's wrong, or try to get a backup.
The fastest way to back up, with the least "thrashing" of your hard drive, would be to start up from your Leopard Install disc and use the Restore tab to make a copy of your internal HD on the external.
That will copy any file system problems "as is," but if your internal HD is beginning to fail, at least you'll have a full copy of the data (corrupted or not) on the external HD.
Check this to be sure your WD drive will boot your Mac: http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/stdadp.php?pfaqid=1787 If not, do all the steps below except #4.
Here's what I'd recommend:
1. Start up from your Install disc, per the yellow box in #1 of [Formatting, Partitioning, Verifying, and Repairing Disks|http://web.me.com/pondini/AppleTips/DU.html]
2. Reformat the external HD, with a single partition, per the blue box there. You'll want the +Mac OS Extended (Journaled)+ Format and either the GUID or +Apple Partition Map+ *Partition Map Scheme* as detailed there.
3. Use the Restore tab to copy your internal HD (almost certainly named +Macintosh HD)+ to the external HD, per #7 in the link above. Note that will copy the name of the internal HD to the external.
4. When that's done, quit Disk Utility, then select +Startup Disk+ from the Utilities menu in the menubar (per the yellow box above). Select the external HD and start up from it.
|
The copy may take a very long time. There will be a progress bar, but they're notoriously inaccurate under the best of circumstances. If it completes, and you can start up from the external, post back and we'll see if we can find the problem, and either fix it or confirm that you need to take it to Apple.

I have yet to isolate this doesn't happen on other drives, but I already relocated the FRA, because a different external drive was too slow.
(and archivelog failed because of this)

Hi Sybrand,
I just wish to please check below:
1.As Aman suggested to deinstall anti-virus program
2.free space on external hard disk
3.Path and Permission issue (if any)
4.May be filesystem of the external drive issue
5.May be issue of filesystem size limit.
5(i).FAT32 is 4GB and NTFS is 16 exabytes. FAT16 (mainly DOS) was 2GB, but some instances supported 4GB. A windows server class machine is almost 100% going to be using NTFS. Same issue on SQL Server with a local account trying to do things on an NFS. Use a domain account/NTFS.
