Hard Drive Is Flickering:

I have been podcasting...downloading lots of the free ones... and some of them are a few megabytes but some are 1/2 of a gigabite. This takes up space, and also OS X And OS 9 on the same 10gb hard drive. There is 1.5 gb left.
My 80gb samsung hard drive connected to USB, keeps getting "Device Removal" again, and I opened Disk Utility and it said something like "It is a 1 and it should be 0." and it did not repair it. }=[ It still mounted it, and it has all the files and nothing appears to be damaged or missing, but it kept not-ejecting the hard drive. It began when I transfered a large podcast file onto the external hard drive and Finder hung on the transfer. Finder itself did not freeze up, it was simply not finishing the transfer file. I forced quit Finder and it would not come back up. I went into Terminal and typed
/System/Library/CoreServices/Finder.app/Contents/MacOS/./Finder
and it came up. and it froze and then I typed killall finder and closed out of Terminal and re-opened it. Finder launched by itself this time with no problems... but I ran disk utility and my disk is messed up. That's it. I am going to connect the large hard drives to OS 9 only, and to transfer files off of OS X, I will use SD Cards with a USB adapter.
And in a few weeks I will buy fire wire enclosures. I hope very much that the fire wire won't have the same issues that USB has. It is plugged into USB hub now. The hub is self powered...and plugged into its own power strip. I know I shouldn't use USB hubs, but it can be difficult to have the hard drives plugged in, sync-ing an ipod, etc. all at the same time, and it annoying to have to unmount and disconnect routinely. Also...all my mp3s are stored on the external drive...so that is one reason why I had the ipod connected to the imac, and a hub connected to the imac with everything else (keyboard, mouse, and one of the USB enclosures) so I could easily have mp3s on my ipod.
But the only thing I did when it hung was transferring one (very large) podcast from internal hard drive to external hard drive.
Anyways, I have more "Computer Trauma" and do not ever want to connect external hard drives while running OS X. even with fire wire.
Also I am not going to bother moving files off of damaged directory hard drives with USB. I hope Fire Wire will be MUCH faster.
===========
And This Is Where I Am Now:
I connected USB enclosure with the 80gb Samsung directly to an imac with OS 9 booted and I turned on the enclusurer. The volume mounted instantly. Files could be accessed instantly. I also transferred some files on it to see if it would let me or if it would display an error message. It let me put files on it.
But........
Why was it flickering for like 10 minutes???????????????
The light was flickering from green to red a lot.
Is this "Mount Check" ?????????????
I thought Mount Check turned the arrow into a watch and the clock froze until the volume could be mounted. But the volume mounted, nothing froze, but the mouse arrow was slow and choppy for a while. It has stopped flickering. The light on the enclosure is green. What was OS 9 doing?????? Mount Check????? Defragmenting????? Repairing a directory?????? =S
Also.........sometimes when I had it connected it to OS X, OS X was doing something to my hard drive. =S I don't know what, but I wanted to eject the drive and it wouldn't let me!!!!!!! }=S I did not have any applications open such as iTunes, which could have been Using the hard drive. =S
And..... since I have discarded my 120gb maxtor, and the 20gb Western Digital and a 20gb Maxtor got zapped by that Blue And White power mac g3. ... I am using a damaged 80gb seagate.
I connected it. Nothing was on it anymore. But I connected it to OS 9. I erased it, because it said "the disk could not be read". It formatted it as
40gb!!!!!!!!!
And. every time I mount it, It says "...disk could not be read...", and if I select, "Eject"...
It mounts!!!!!!!!! =S
I can store files on it. I am not going to attempt to connect it to OS X. But OS 9 mounts it, even when it is damaged.
I appreciate lots of advice.
What I have:
= 80gb samsung with a 1 that should be a 0.
= 80gb seagate with damage but os 9 formatted it as 40gb and if I select eject on the error message, it mounts it instead.
= 2 imacs. One with a os 9 startup volume, and one with a OS X startup volume. Both with OS 9 drivers. imac g3s.
= 2 USB enclosures. But I am going to get Fire Wire. and some large drives. (should I get SATA, or 2.5 inch... or do these cost more????????? )
= AC adapter USB hubs... 7 port, with LED, and connected to its own power strip. The enclosures also have their own power strips. No, the power strips are not plugged into each other.

I appreciate any advice that people have.
It is possible that one of my enclosures has faulty power...something could be loose. An error message occured once while transferring files with OS 9.
I am still going to use OS 9 to move files and organize files that are in external storage because in my experiences, OS 9 is less likely to cause directory damage in the event of some power failure.

My Lacie hard drive back up is not showing up and light is flickering

My back up hard drive is not showing up when i plug in the USB to my Macbook Air so won't back up. The light on the hard drive is flickering. CAn you please help?

A: does it show up in disk utility?
B: try a different USB port.
C: If no go, try a different Mac.
D: If still not recognized then its about 90% likely the SATA bridge card inside the USB enclosure is bad....NOT the Hard Drive itself, but the SATA bridge card attached to same.
Is your Lacie a conventional HD or a SSD? (LaCie does NOT make hard drives, internal conventional HD are Seagate inside a LaCie)
If its a conventional HD
A replacement HD enclosure will solve same, ($15 ebay). The Sata card removes from the HD very easily, like LEGOs attached together come apart.
Verify A thru D first before doing anything.
likely bad part pictured below, the SATA card, ... as seen INSIDE a USB external HD

T61 hard drive error

hello everyone,
I have had my lenovo t61 for over 6 months now, and till yesterday it was a rock solid machine. However I have now encountered a problem that is really posing problems for me. I would appreciate it if you guys can have a look at the symptoms and help me out
Lenovo T61
Windows XP Professional
Intel Centrino Core 2 Duo
2 GB Ram
yesterday after i booted the system up, the 'processing' light (the one that flickers with CPU activity) would not stop flickering even half an hour after the system had booted up. Loading of programs had tremendously slowed, with some refusing to open and some not responding. I rebooted, same problem. I system restored to a week back when I wasnt experiencing any of this, but no change. Upon checking the task manager, everything was at 0 except for system idle process which was at 99. CPU showed a use of 4%, which seemed normal. But the processing light kept flickering and programs would be extremely slow to load.
I left the PC on and came back after a couple of hours and I saw a blackscreen with white letters (like DOS) saying I had a 'hard disk initialization error'. Next time I booted I listened to the CPU closely, its not making random sounds, but seems to be stuck in a loop, the same kind of whirring just repeats over and over again.
Next I booted in safe mode with networking, the processing light flickering was reduced and I tried to backup my system... but many files would not copy and I got an I/O error for these...
I did some googling on this and one possible solution I got was upgrading the bios to version 2.14-1.08 (april 2, 2008). Now Im not sure if I should do this, incase the entire thing becomes worse.
I would appreciate any advise you can give me.
Thanks so much

@ alap. welcome to the forum,
please try the following two suggestions; remove and reinsert the hard drive to esure that it is connected properly. If this doesn't help, download and create a bootable cd from the iso file of Hitachi's Drive Fitness Test.
@ cputrooper, also welcome,
I suggest you should also try both of the above. Are you hearing a specific number of long / short beeps? Calling service was a good call HDD removal is the same as for T61.
Please let all know how you the results.

Mac Pro 3,1 - did my hard drive die? And what should I replace it with?

Hi,
I inherited my late husband's 2008 Mac Pro (3,1 model) which had 2 x 500GB hard drives in it and 6GB of RAM. I filled the remaining hard drive bays with 1TB drives (I take a lot of video so needed the extra space). The boot drive was partitioned 50/50 in Boot Camp. I've upgraded the RAM to 10GB and I am currently running Lion.
Today, while doing something as innocuous as scrolling down a web page, the bottom half of my screen went black and the top half began flashing wildly. When it stopped after several seconds, the mouse would not respond and I could not click on anything. If flashed a bit more, and then I had mouse control back but could not click on anything - web links, applications, finder. After waiting patiently but getting nowhere, I powered the machine down manually, and when I re-started it, it failed to boot. The chime sounded, the apple appeared, and the little revolving wheel, but at the point where the screen would normally go blue then display the desktop, it just went white. The fans spin, but otherwise it's very silent.
I tested with a second display, got the same issue. I tried booting to recovery mode but it went back to the white screen. I could start in target mode, and there were no issues with flickering screen, so I don't think it's the graphics card. Then I tried browsing to the hard drive over the network, but it wasn't showing on the PC network page, nor could I connect to it via the home theater system, which I can normally do as the streaming app launches on start-up. I am assuming this means the drive has failed? It's the original, and we bought the machine when they were new to the market, so is a good 5 years old. It contains not only the boot drive but my documents, photos, websites, selected videos, all of which are backed up on the Time Capsule, and I was in the process of uploading to cloud backup as well (although not very far along, due to data cap and slow international upload speeds). I had no warning it was about to do this, but then I guess sometimes you don't!
Assuming I need to replace the drive, would it be worth replacing it with an OWC Mercury Electra 480GB SSD in an Icy Dock sled? Or would that be overkill for such an old machine? Would getting a standard 7200 WD Caviar HDD or similar give me enough of a speed boost? Obviously I am rather enamoured with the idea of a blazing fast SSD but I'd have to import it (not available locally) so I don't want to shell out all that money unless it's really going to make a massive difference.
Is there anything else I would need to know about using an SSD over a HDD? I assume I would fire it up the normal way - install it, boot from my Snow Leopard install disc (I downloaded Lion from the App Store) format it, clean install SL, then re-update to Lion, then restore my Time Machine backup? Am I likely to experience any weird issues due to it being an SSD? I see talk online of firmware problems and something called TRIM that I don't know anything about. If it's most likely that I can install it and rock on as normal, then I'm pretty keen, but if there's a reasonable probability of it being temperamental, I probably wouldn't be willing to deal with that (and therefore go the HDD route instead). Therefore I am very keen to hear people's opinions and experiences.
Sorry for the terribly long ramble. The more I have researched this, the more questions it raises! All advice gratefully accepted. Thanks!

more than likely it is your video card. If it is ATI 2600XT, tell it bye-bye. The card is barely used at all in TDM or Safe Boot Mode. The 2600 and Lion and the issues with that card, even if it seems okay, is not.
Depending on Windows OS as to how it mounts and sees your Lion HFSX (there is a nice HFSX driver from Paragon, and an NTFS driver for Lion too)
480GB SSD is overkill for any system unless you are pushing CS6 2-3GB images and then for scratch. All you need for a boot drive is about 100GB.
If you have an SSD now, then 1) you need to do a full image backup and restore (regularly as maintenance), and 2) TRIM Enabler
Save Lion and you can always do a clean Lion install w/o going back to SL - but you might want to keep SL (dual boot) and handy if you run into anything you still need that required PowerPC/Rosetta
FBDIMM RAM dies, Amazon has $32 kits of 4GB. And having all 8 DIMM slots filled improves things. If you need or want to and feel 16GB isn't overkill.
SSD and issues are always possible. you should not just go along. not without a clone image. And you should have another drive w/ TRIM Enabler so that you can do a repair and "trim" what is needed.
Clone a system with CCC regularly. Bootable. And can also be used by Setup Assistant.
Install Lion over a heavily used SL system and there are likely remnants of old things that get in the way and left in there and not removed.

I think my hard drive crashed. How can I get data off via firewire before the HD completely goes? I was stuck on the BSoD and now I can't even use the install disk. Utility Disk said HD was okay. Please HELP ME

Safe mode did nothing.
Safe mode with verbose seemed to make it worse.
Before continuously trying new things, I could use the install disk to check the disk utility and clear
the hard drive from there but now the screen won't even load to that.
I really need the data on the hard drive especially if it can't be salvaged.
How can i transfer files?
Am I better off physically taking my HD out or will it damage itself without
leaving the system.
I tried command r
resetting the pram
safe mode
jumping out a window
nothing has helped.
I am stuck on the blue screen of death and it flickers.

No. In order to use FireWire Target Disk Mode you need to use a FireWire equipped Mac. Other than that the only other way I can think of to even attempt to access you files would be to remove your hard drive and install it in a case and connect it to another computer.

Hard drive constantly running and ruining battery life

Hello,
I recently got an x200s from a legit ebay lenovo seller that came with an upgraded 500gb 7200rpm hard drive.
The problem is that the hard drive is running at All times. I can tell from the sound as well as slight vibration. Even with the lowest power settings, and just letting it idle, it runs. I tried playing with the power manager, and having the hard drive stop activity after 30 seconds of inactivity, it keeps running. I turned off indexing on the c as well as the lenovo back up drive, its still running. The hard drive activity light is only flickering, and the processes seem totally normal. What is up?
I'd say this also has to be the reason i'm only getting like 2 hours with the 4 cell and very low power settings, which is unacceptable.
Any thoughts?
Thanks guys

Nah...if you choose a less-than-sensible setting in BIOS, an arm holding a hammer will come out of the LCD and smack you...that's a part of ThinkVantage that only a few people know about...
How many processes do you have running on a freshly booted machine?

External USB Hard Drive Not Recognised / Seen

Hi,
I have a WP 250 GB External hard drive which was working fine until recently and now is not recognised by my 2007 Intel Macbook. When I plug in the hard drive, a light comes on solidly and it begins whirring. Then, it continues to whirr as if it was going to work, but the light starts flickering.
It is not visable as an external hard drive in finder. 'View Hard Disk' is switched on under Finder / Preferences. On System Profiler, when I click 'USB' fom the list on the left, the computer displays the circular "thinking about it" spinning thing, and system profiler freezes, and nothing else happens. The same thing happens with disk utility.
I tried plugging the hard drive into a windows computer, and it worked fine; all the files inside it were visable. It is formatted to my mac and I have successfully used the hard drive many times before. A logical next step would be to try it on another mac but I don't have access to one.
I have tried to to a PRAM reset, but couldn't do it, even following the instructions on the MAC website (turn off computer, turn on and hold the mac button, ctrl, p, and r simultaneously) it wouldn't do a PRAM reset.
I am not a computer expert, but I am not completely green either. Why is it that doing the simplest thing on a computer requires a minimum of a 4 year computer science degree or equivalent.... somebody please help me crack this, I am close to smashing the whole thing to pieces with a hammer (which would be satisfying but counterproductive and expensive...)
Thanks in advance for your replies

Did you allow Windows to upgrade the formatting on this drive from FAT to NTFS recently? You should be able to check the formatting on the volume from within Windows. It would also be worth trying to repair the drive under Windows if it allows you to.
Note that NTFS is not readable under OS 10.4.x without special software. NTFS is read-only but not writable under OS 10.5 and later.
If the volume isn't NTFS, and repairing it doesn't help, you may need to just backup the data and try to reformat it.

Repeated hard drive failure in a few months

Hello everyone, I own a 15.4" macbook pro, bought in october 2009 directly from an apple operator by phone; on february, after just 4 months, I wake from sleep mode my mbp and I see the "beach ball" spinning cursor, and the system freezed. After a few minutes of freeze, I am forced to shut it down by keeping the power key pressed. I reboot, and the only thing appearing is the folder with a question mark on it.. I manage to recover a lot of my data ONLY using Disk Warrior, which warns me that my hard drive is severely compromised. I didn't notice any problem
in the previous days, it just happened from one day to another. I'm out of luck.. but still it's something that can happen. Apple changed my hard drive immediately.
Today, after less than other 4 months, the same problem. I open my laptop, it wakes from sleep and it remains freezed.. I fear the worst. At reboot, at first it showed the folder+question mark, now only the "deny" sign (circle with a bar). The hard drive doesn't make any weird noise nor click, but restarting with a Ubuntu I just manage to recover a few files before getting a lot of input/output errors. Now I can't see my hard drive anymore listed among peripherals, neither using Disk Warrior which recognize it, but It cannot communicate with the hard drive.
I'm still under warranty, so Apple will change my hard drive but..
a) is it possible that a hard drive fails from one day to another without any symptom in the previous days? It worked like a charm, and suddenly it broke. In both cases.
b) in your opinion, is it possible that I'm just out of luck or it cannot be a coincidence? Could it be a power supply problem, or a sata controller failure? In this case, how does Apple behave? Just substituting the hard drive for the second time wouldn't be enough, I think..

Hello LorenzoMarcon
a) Apple is usually very good about picking the hardware that goes into their machines. But yes it is possible you had two defective drives. The trouble with hard drives is, they are really not designed to be moved around. The tolerances inside a laptop drive are so tight than almost any defect will cause the drive to fail.
b) From the description of the failure and the fix I think it is just your drives failing not a problem with your machine. If you had a power supply issue you would notice other issues with your mac; flickering screen display, odd shutdowns, charging issues, or excessive heat. A SATA controller failure would cause your drives to just not show up since you recovered the first drive with disk warrior the controller is working.
That covers the hardware side of the problem there is another component here that might be affecting it, the environment around the mac. A sudden jar or impact can cause drive failure. There is also a brief window when you have put the mac to sleep but the drive has not finished spinning down where a sudden change in orientation could cause the heads to crash into the drive platter.
I hope this helps.

Need Help with my External Hard Drive

Hey Guys, so i bought a 2TB WD Passport for Mac about 2 months ago...It worked great, but then i dropped it by accident. It was connected to my Mac at the time, so when it fell it disconnected from the cable and fell. Now when i connect it, the external hard drive powers on. I can feel it on like always, the little light turns on as well, its flickering as if it was in use. The thing is that it wont show up ANYWHERE on my mac. Any help?

HEAD CRASH ,    your HD is extremely likely kaput
hard drive moving parts
Some of the common reasons for hard drives to fail:
Infant mortality (due to mfg. defect / build tolerances)
Bad parking   (head impact)
Sudden impact /head crash (hard drive jarred during operation, heads can bounce)
Electrical surge   (fries the controller board, possibly also causing heads to write the wrong data)
Bearing / Motor failure   (spindle bearings or motors wear during any and all use, eventually leading to HD failure)
Board failure   (controller board failure on bottom of HD)
Bad Sectors   (magnetic areas of the platter may become faulty)

External Hard Drive No Longer able to Mount

When my dad's iMac G3's power died we turn his G3's internal hard drive into a external so he could mount it to his new user account on my iMac G5. It's been fine until I recently had to force power of my computer. Now his G3 HD won't mount. We have 2 other externals connected. A USB 2.0 Maxtor connected for my Time Machine and his Firewire OneTouch used for his iTunes. Both of these still mount and work fine.
The OneTouch is connected to the G3 through firewire then they are both connected to the computer through a single firewire. Since the OneTouch still mounts I know it's not the connection.
We've tried using Disk Utility to repair and that says it's fine. It does show up there and can be checked but is grayed out and will not mount.
He has a book file he's working on, that he hasn't backup elsewhere along with apps that were purchased and have no way to recover so we can't erase this volume. Is there anything we can do to get this to mount like it has been?

Okay, yeah I knew that was a "duh"
That light isn't flickering, it's on steady. It's the drive indicator light that is doing nothing.
Turns out he had been saving the book to my hard drive and not his external like he thought so everything is there and backed up to Time Machine. Now we just need to purchase iWork to replace his Microsoft Office which was on the old drive and the reason he thought he was backing up to and working on his old drive.
He would still like to get the G3 drive mounted again but turns out he lost nothing.

Is there a way to get data to and from the hard drive of a Powerbook 180 without having to use the floppy drive?

Howdy folks!
I have an 20 year old Powerbook 180 with what I think is an unreliable floppy drive. Sometimes while accessing a diskette the screen flickers and usually power to the whole computer drops out.
I'm not familiar with Mac connectivity. Is there a way to access the hard drive--to get data off of, and install files, etc onto, the hard drive? 3.5 inch drives are 20th century.
But... I am happy because my old Powerbook still boots up just fine and I can look at my old files installed on the HD ok.
Thanks,
Hayward Matt

Hi Hayward,
This may be a power supply issue, not necessarily a problem with the floppy drive itself. Any change if you try removing the battery?
Would it be correct to assume that it is a plain PowerBook 180 (not 180c)? Which power adapter are you using? It must have a 7.5 DC output, but is it capable of supplying at least 2.0 A?
Unfortunately it is difficult to remove and connect the (2.5" SCSI) hard drive to a modern computer. Had it been 2.5" IDE, things would have been much easier.
It is possible to set up a serial null-modem connection from a PowerBook 180 to another computer. See the following discussion for details:
https://discussions.apple.com/thread/4974860
If the PB 180 has an internal modem (or an external modem connected to the modem port), you could send files to another modem-equipped computer over the phone lines. With the proper software installed, the PB 180 can even use a dial-up Internet connection.
Alternatively, another semi-old (pre-1998) Macintosh computer with built-in Ethernet could be used as an intermediary, You could use LocalTalk (or a plain Mac printer cable) for file sharing between the PB 180 and the semi-old Mac (the latter could then forward files over a local network or via the Internet). It is also possible to connect the PB 180 to the semi-old Mac in SCSI disk mode (see the user guide below for additional information).

Problems with Monitor after Hard Drive Replacement

I never had any problems with my iBook G4 until the past 6 months. I sent it in once because it wouldn't start up. They were able to fix the problem without replacing the hard drive. It malfunctioned again and the second time they had to replace the hard drive. I've had it back for about a month and 1/2 now and for the past three weeks, whenever I try to use it I get problems with my monitor. I'm not sure if the video card is going out or what? The image on the screen gets chopped up in horizontal and vertical line increments. Its really hard to explain but sometimes it comes in waves and I have to shut down my computer and walk away from it. Other times like right now, I'm able to use it for up to an hour but then it gets choppy again and I can't use it. My Apple Care Protection Plan expires in December and I want to get as much from it as I possibly can before I have to replace the laptop altogether.

sorry,
to clarify, "internal or external;" display
internal = ibook display
external = display connected via display adaptor
Ok, well I max out the graphics on my ibook on regular intervals (games, high-end graphics work, gigabyte photoshop files etc...)
It isn't likely to be the hardware, so here's some suggestions.
LOOSE WIRES/CABLES:
The ibook's internal monitor connects through the central pivot where the ibook opens, the wires in here may be damaged. (you can't fix this yourself, refer it to apple) this could pertain to a loose or defective cable is you are using and apple display connector also.
REFRESH RATE: (this sound like your problem)
to quote a source:
"If the refresh rate is not properly set the monitor may have a wavy or an appearance that lines are going down or across the monitor slowly or fast. This may also cause a flickering affect."
http://www.computerhope.com/issues/ch000242.htm#02
This is set in display preferences. try setting your monitor's refresh rate. (75hz is good)
INTERFERANCE:
Monitors are succeptible to electromagnetic interferance: Speakers, hard drives, phones etc. try moving them away from the monitor.
BAD MONITOR:
finally; and we hope this isn't the problem. if you are not already doing so, connect an external monitor to the ibook using the display connector (VGA only), if the issue persists with the external monitor the problem is software based, if not you probably have once of a small percentage of monitors that just goes "bad" after a time period, unfortunately it's often cheaper to replace an entire unit as opposed to the screen itself (new computer)

Installing Windows XP on SATA Hard Drive

Hey. I have a maxtor 80gb SATA hard drive that I put in my new computer, and I want to install Windows XP on it. I see that the computer recognizes that it's there, but when I do the F6 process to get the drivers for Windows I cannot get anything for some reason. I hit F6, and it gets to the point where it asks me to install a disk with drivers, and I put the floppy for the VIA drivers in the drive (I'm using VIA after all I've read), and nothing happens. I don't even hear the floppy doing anything. after a few seconds of "please wait" the same screen comes up telling me to put the floppy containing the drivers in. Does anyone know what the problem could be? Also, in bios, it seems to recognize my floppy drive, since it lists it, and I can use it as a boot drive. If someone could help me out, I'd appreciate it. Thanks.

Hi
What is meant is the floppy is controlled from 2 parts of bios.
1. go to advanced bios features, set floppy seek to enable, set boot sequence to floppy, CD, HDD(BB1 = SATA), enable other devices. Then go to integrated peripherals, make sure PATA IDE and SATA IDE are enabled, just below is floppy controller, enable that, then SAVE and exit,
If the floppy cable was inverted, the drive light would be on all the time, if it flickers oon and off, it is OK.
Now try the F6 routine, if it still does not work then a new copy of floppy may be needed.
Cheers

Cannot Access Toshiba External Hard Drive On MacBook Pro

I have had this Toshiba portable external hard drive for about 3-4 years now. It is powered through the USB port (USB 3.0 I believe, but maybe it's older and is only USB 2.0). All of a sudden my hard drive will not show up on my Mac or PC to be accessed (on the PC it says "device descriptor request failed" and doesn't show at all). At first I thought it was because I updated to Maverick when it was first available, but realized I had been accessing my hard drive and using time machine with it since then. Right now there are a lot of files on this hard drive I would like access to so I do not want to format the drive at all. Furthermore, the drive appears in disk utility and I did the verifying and repairing disk functions in disk utility and they were successful, but nothing was actually fixed. Also, the light is constantly flickering white, sometimes it would be solid blue, but recently only flickering white.
I have also refereed to this discussion thread, however, in this person's situation their drive does not appear at all where mine actually does. The solutions provided were to try a new cable or that there is not enough power being provided from the computer through the USB cord into the hard drive. I have never had this issue and have tried both cords made by Samsung and one from a WD My Passport. Please let me know if I should try the powered USB hub and I will, I just don't understand why the power going to the drive changed all of a sudden since I've been using it for years.
I have already ordered a new external hard drive so I can back up my computer, but I still need the files on this hard drive. Luckily it seems to still be alive which makes me think there is a way to get the files. So if anyone can help me figure out a solution to this problem without losing my files that would be excellent.
Thank you. I will try to provide you with any additional information you would like to know.

Since you can see the drive in Disk Utility, select it, go to the Restore tab, and use that to copy the data to a new drive. Note the warning on reformatting the destination drive - make sure there is no data on the new drive.

Canvio 1.0 TB USB 3.0 Portable Hard Drive HDTC610XK3B1 Sluggish

Bought a Toshiba Canvio 1.0 TB USB 3.0 Portable Hard Drive (HDTC610XK3B1) back during Black Friday 2011. Since I've had it, I've used it on my laptop, my rather powerful HP desktop, and another pretty powerful ACER desktop and all exhibit a very weird problem with the hard drive. Almost as if it's going to sleep or becoming idle, if I haven't accessed it or used it in some time (say I open an image that's on the drive and work on it for 5 minutes in photoshop) and go to either browse, save, or just about anything that would require access to the drive, things lock up for about 15-20 seconds and as I watch the hard drive (which the light will be off) the light will suddenly come on flickering which will then unfreeze the system and I have access to the drive.
It's the only potable hard drive I have that's doing this. I'd imagine it's some sort of auto sleep that it goes into and when you 'awaken' the drive to use it it takes a few seconds to power back up... but that's just my theory. It makes things go very slow when you're working on lots of images on the drive, so any help would be very much appreciated!
What would be causing this momentary freezing as it is accessed? And is there a way to turn this off?

Hi,
I have exactly the same problem... with both my Canvio 1TB drives. (One is a HDTB110XK3BA, the other a HDTC610XK3B1.)
For some reason, NoSleepHD wouldn't install. (Could be because I have a 64-bit system.) As for Linux, I don't have it installed, and I'm no computer technician.
Isn't there a an easier way to get rid of this very annoying problem?
Thanks!
