Secondary internal hard drive disappeared from desktop after forced restart

I have three internal hard drives, one for system, the other two for data storage. While permorming a search on one of the data drives i clicked the "X" to the right of the spinning wheel on the bottom right of the search window to stop the search but the computer froze (wheel kept spinning). I then went through the dock and quit all applications, except for InDesign which wasn't responding to force quit.
The only way out was a force restart. Upon restart, one of the internal data hard drives did not show up on the desktop, nor after a couple more restarts, nor after restarting from the installation disk, verifying and repairing disks and permissions on the other hard drives with disk utility.
where did it go?
G4 Mac OS X (10.4.9) Dual 1.25 GHz, 2MB L3 cache each, 2GB DDR SDRAM

no it doesn't show up at all in those either.
Hmm. Then that sounds like the interface to the drive isn't even talking. You could try opening up the computer and making sure the cables are all connected firmly (of course, it should be off).
here's the log:
Nothing here looks too alarming.

Hmm. These are part of Spotlight, but they don't really give any clues, just that they weren't responding. Which might be because the drive disappered during your search.

Unfortunately, I don't see anything helpful here. It's just like it disappeared (or never existed) as far as the OS is concerned. If you can find your original disks that came with the computer, you could try running the hardware test and see if it kicks up any errors, either with a drive or a drive controller on the motherboard.

Internal RAID Drives Disappeared from Desktop & Finder

A few days ago, one of my two internal mirrored RAID sets no longer showed on the desktop or in the Finder Sidebar. A day later, the other internal RAID set disappeared from desktop and sidebar. The two remaining internal non-RAID drives show up as do two external drives. All internal and external hard drives still show under Disk Utility and Photoshop Bridge CS3.
I checked Finder Preferences and boxes are checked to show internal and external drives on the desktop and sidebar. I looked at the drive detail under Disk Utility and nothing looks wrong with the two RAID sets ON-LINE. I unmounted one RAID set and re-mounted without any change. I tried unchecking the two preference boxes to not show the drives and rebooted, rechecking the boxes and rebooting and nothing changed on the desktop or sidebar.
Does anyone have any suggestions to resolve this?

Well our invisible drives problem is resolved but it's not the solution that I'd hoped for.
We visited the Genius Bar at a local Apple store and they denied any knowledge of problems with invisible drives in Macs and discounted my reports from Mac forums.
I went home and ordered a new 1tb Seagate drive. When it arrived, I installed it in bay 2, copied each invisible drive to the new drive one-at-a-time, broke my two sets of internal mirrored drives, erased all the affected drives and reloaded them. Now all drives are visible on the Desktop and Finder again.
I'm hoping that the disappearing drive problem doesn't surface again but view this as an unresolved Apple issue. Now I can look at other mass storage options for future growth.

External Hard Drive disappearing from desktop

I recently bought two external USB drives to use with Time Machine, one for my PowerBook G4, and one for my iMac.
The one that I connected to my PowerBook at home works without a problem, but the other one, not so much.
I use my iMac in the classroom, and I set everything up to work with Time Machine. No problems. The drive was recognized, I reformatted it, and the initial backup finished without a problem. Then, later, I noticed that the hard drive was no longer showing up on my desktop, and checking Time Machine showed that things hadn't been backing up hourly as they should have been.
I launched Disk Utility, but the hard drive didn't show up, so I couldn't mount it that way. Plugging and unplugging the USB cable didn't help, so I shut down the computer and turned off the hard drive. I turned the drive back on and then restarted the computer. It was back, and Time Machine immediately started running again.
But then later the drive disappeared again! I went through the same process as before, but this time I switched the USB ports before I restarted. It was back.
But then later, it was gone again.
The other strange thing is that even when I restart the computer, the drive doesn't reappear unless I've turned the drive off.
Any suggestions? Is there some auto-unmount and never come back again option in Leopard that I'm not aware of?

Does the drive even show up in Disk Utility? If so, run Disk Utility and verify (and repair if necessary) the drive:
[Resolve startup issues and perform disk maintenance with Disk Utility and fsck|http://docs.info.apple.com/article.html?artnum=106214]
[Using Disk Utility in Mac OS X 10.4.3 or later|http://docs.info.apple.com/article.html?artnum=302672]
if it doesn't show up in Disk Utility and you don't have any other copy of the files you will need to try a stronger utility such as [Diskwarrior|http://www.alsoft.com/DiskWarrior> to try to repair the drive. Otherwise you can try to copy off the files using a utility such as [Data Rescue II|http://www.prosofteng.com/products/data_rescue.php] or [FileSalvage|http://subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1].

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

My second internal hard drive disappeared

My second internal hard drive disappeared a couple of days ago taking many gigs of iTunes with it. It does not appear on the desktop, finder or anywhere else. When I click on a song in iTunes I get "The song “Cowell: Set Of Five - 4” could not be used because the original file could not be found. Would you like to locate it?" When I try "locate," well it shows me the Main Disk. Not helpful. I've read lots of posts about vanishing drives and crashing drives on Leopard (I run Snow and was about to go to Lion). Did my drive die or did it go into the witness protection program? Irony is that I bought a 2 TB external drive last week to back up the iTunes drive and procrastinated. Suggestions? Experiences?

Is it listed in Disk Utility?

WD My Book backup drive disappeared from desktop running Lion

WD My Book backup drive disappeared from desktop running Lion !0.7.5. Disk Utility recognized the drive and has repaired it, but it still does not show up on desktop or Time Machine. My Book also appears to hold zero data now (I've had it running backups for a couple of years). What's the problem? How to remedy?

I tried this but it did not help. I did confirm that the external drive is working by connecting it to another IMac computer running Mavericks. Not sure if the recent update to Yosemite that supposedly fixed issues with time machine has messed this up or not. Trying to work with WD as well to see which side the issues is on. I remember a similar issue with Mavericks was updated making time machine unusable with the external drive.

Will Apple stores in Germany replace your iPhone if there is internal hard drive problems from a phone from the US. I am studying abroad and won't be home until December

Will Apple stores in Germany replace your iPhone if there is internal hard drive problems from a phone from the US. I am studying abroad and won't be home until December

You can try, but the iPhone warranty terms state that Apple "may" restrict warranty/service to country of original purchase...key word here is "may".
Good luck.

Mac not reading internal hard drive, running from external

I have a Macbook Pro, that stopped working on me.
After some tinkering around, I was able to boot up after it crashed, but only by removing the hard drive and accessing it through the USB ports.
Two part question...
A- How do I see if the computer is recognizing the internal hard drive? (I purchased a new one and placed it in the unit)
B- How do I clone the old hard drive, now external, to the new hard drive?
I also was not able to partition the new hard drive yet
thanks!

If the drive mounts through a USB, it should be OK. The cable connecting the HD to the logic board inside the system may be faulty. That service/part runs around $75 and can be had at the Genius Bar.

Ext hd drive and 1 int hd drive disappeared from desktop

so i fire up the old mac and i notice that both my external hard drive (used for time machine) and internal hard drive 1 have both disappeared; i went into disk utility and found the internal drive; it showed as not mounted so i mounted it; BINGO, there it is..... but, no ext drive in disk utility, so i hooked it up to my other mac and there it is in all its glory; i'm not sure what to do next;

Finder->Preferences->Sidebar->Devices->select Hard Disks and External Disks, for starters. Then, OPTION-click and hold on the Finder's Dock icon and select Relaunch.

My imac internal hard drive switch from hsf to fat 32 or ms-dos(fat)

You are non addressing Apple on these forums, we are all end users like yourself. Take your machine into an Apple Store or AASP, they will help you clear up the mess you have created.

Disks disappeared from Desktop after 10.5.4 - 10.5.8v1.1 update

Hi,
a strange think happend today after a server update from 10.5.4 to 10.5.8v1.1 with a downloaded combo installer: After the reboot 3 of 5 1 TB firewire disks disappeared from the desktop! Just gone. What makes the whole thing really tricky: they show up in the disk utilities as mounted! Repairing them doesn´t change a thing. Disk Warrior doesn´t help. What´s even more mysterious: Opening the terminal, cd to the /Volumes folder ls shows folders for all five disks. But "ls -l" produces an "Access denied" error for each of the missing disks! It requires a sudo to show the permissions of the disks! What´s more disturbing: The permissions of the disks not showing up are ending with an "+" while all the other disks have an "@". But what really knocks me of that you can mount and work with the missing disks over the network! I really need help with that.
Greetings,
Mike

Hello mibobby,
I'm seeing something similar to the problem you reported here. I my case there are 4 external hard drives connected to the Xserve 10.5.8. All drives are visible from Disk Utility, The Finder, and terminal. However, if a drive is plugged into another system, 10.5.8, or 10.6.2, the drives will not mount in the Finder. They appear in Disk Utility, but the volume appears as a blank piece of paper rather than a hard drive icon. If you navigate to the volume vial the terminal, you get an error indicating that you do not have permissions. Any thoughts would be appreciated.
Did you ever get your problem resolved?
Thanks
Dean

Folder disappeared from desktop after installing iTunes 12.1.0.5

I recently had to upgrade to iTunes 12.1.0.5 so that I could get the computer to talk to the phone again. The next time I restarted the computer a rather large folder that was on the desktop had simply vanished. The folder lived there for over a year and contained many different items including documents of all sorts, photos, video and audio files, pdf's, etc., each in separate folders within the one parent folder. None of the missing folders or items turn up in finder now. When I go to open recent I see some of the items, but they will not load. I can click on them but nothing happens. I downloaded recovery software (disk drill, stellar pheonix) both of which turned up long ago deleted files and lots of stuff I've never seen before (presumably apple stuff, sound bits, random stock photos and video), but so far none of the items from the folder. It seems rather odd to say the least. I have always used mac's and have owned 3 or 4 different computers over the last 20 years. I have always kept folders on the desktop and I regularly run disk utility to reset permissions. I do back-up onto an external hard-drive, though some of these files had not been backed-up yet. I can most likely reconstruct most of what was lost. I am not looking for advice on how to keep this from happening again as it seems to me there is no logical reason that a folder would just disappear or magically find its way into the trash. My question is this, has anyone out there ever encountered this and if so, were you able to recover the folder?
Thank you.

Thanks to all who have replied so far.
Also thanks to my brother who found a post from user s49 on Jan 3, 2013 in a response to a problem from a user who had the same problem in iTunes 11. I'll repeat what s49 did here since it solved the problem without having to change any security settings.
* First open the terminal program found in Application/Utilities folder
* At the prompt type cd /Applications/
* Then type the command sudo rm -rf iTunes.app/
* You will be prompted for the administrator users password, enter it.
* Then go to http://www.apple.com/itunes/download and download the iTunes 12.1 installer for Mac.
* Once the download finishes reinstall iTunes 12.1
Once again, thanks for user s49 for above directions. It appeared that when updating iTunes to 12.1 from the Mac app store that something stayed in the iTunes.app/ directory that caused the problem. lWhat that was I don't know.
Since doing the above steps I've had no further problems with iTunes asking about network connections.

Internal Hard Drive Not on Desktop

A second internal HD that was installed new in my machine by my campus reseller--now in use for over a year--has disappeared from the desktop. It does appear in both system profiler and disk utility. It is a Maxtor Basics 500Gb drive. As it has all my project files on it, I would certainly like to retrieve them (I do have some backups but not complete). Best steps to take?
Thanks,
Karen

What happens when you open Disk Utility, click on the drive or volume name in the left side panel, and then First Aid, Verify/Repair Drive?

2nd Internal Hard Drive Disappearing

I have a Powermac G5 with one 400gb harddrive that came with the computer and a 750gb Western Digital hard drive that I installed about 6 months ago. I never installed an operating system on it the Western Digital drive, it was just for storage of music/photos/video. About a month into owning the harddrive the icon disappeared from my desktop and a warning came up saying "device improperly disconnected." I opened up the computer and made sure the connection was snug, which it was, booted back up and everything worked fine. That has happened 3 times since I've owned the WD drive. Now it has disappeared again, except this time I can't seem to get it back. The connection is very snug. I have unplugged the harddrive and plugged it back in, rebooted a few times and nothing has worked. It would be pretty bad if I lost this drive. Any advice?

Either RMA or put it on a PC and run WD Diagnostics, or do a full low level erase, 7-way write erase the whole thing.
I had one I bought about the same time from OWC and I think I read a bunch of reviews on Newegg about problems with a different batch.
I found a couple areas on the drive that had bad blocks. TechTool Pro media scan can find them but why it doesn't then map them out??? Intech Speedtools is suppose to auto mapout, and maybe it does (all software does is tell the drive to write a pattern 10x and read it back and mark a weak sector as unavailable.... but WDs tool was the only one that really fixed it, not Apple DU 7-way erase, and not even zero all with SoftRAID.
I have about 20 WD drives, this is the only problem I've had, from 10K Raptors to 1TB Black and Green Power and in between.
I'd pick up the 1TB Black, or a couple 640GB Caviar ($69 each! OWC). Or spurge $300 on 10K 300GB boot drive AND 1TB data drive.
