PH3100U-1EXB External Hard Drive

I have an external hard drive that I connect to a Toshiba Satellite C675 laptop. I last used my hard drive on 8/31/12. When I tried to connect it today, 9/2/12, the power light comes on for about 10 seconds, blinks rapidly, clicks and turns off. I have tried to power it on about 40 times and it does the same thing every time. I have also tried to unplug the power cable and let it sit for a few minutes. I have had the hard drive for about three years and have not had any previous issues.
Any help would be appreciated.

I was looking for drivers or software for my old PH3100U-1EXB tonight and cannot find anything. Would anyone know where I might find that? Also is it possible to change this drive from a SATA to USB3? I has the USB 2.0 but very slow. Thanks in advance for any help in this matter.

Toshiba ph3100u-1exb External Hard Drive Will Not Stay On

Hello all.
I recently purchased a Toshiba ph3100u-1exb 1.0 TB external hard drive. It's working great, but the problem I am running into is that it will not stay powered on for more than a couple minutes. I'm sure that its some kind of power saving feature, but if there's a way to turn it off, I'd like to have the drive accessible at all times, as I use the information stored on it quite a bit.
When it powers down, I can always press the power button to bring it back up, but I would like to have it on all the time. Is there any way at all to do this? A setting on the drive, or possibly within Windows?
I have the drive hooked up via a USB cable, as this PC is a bit older and does not use the eSATA cables for hard drives.

Hi
In my opinion the HDD should be checked with different computers and different OS (Vista, Win 7, Win XP). If the external HDD will not functions using different systems and computers then its definitely an HDD issue.
Ive got 2 different external HDDs one HDD died and I had to replace it.
In my opinion, if an HDD begins to malfunction then its mostly an hardware related issue and there is nothing to do as to replace the faulty drive

Toshiba External Hard Drive not recognized by computer. Please help!

I was wondering if anyone could help me. I have an external hard drive and it will not show up in "My computer" when I plug it in. I have tried other USB drives and other computers. I am starting to think it is a hardware issue but I don't want to lose hope. The blue light is coming on when you plug it in but it doesn't blink and there is no noise whatsoever. Is there anything I can do to fix this issue so that I can recover the information on it? Thanks in advance for any help. It is greatly appreciated.
Additional information: I'm not sure how old this thing is but the model number is HDDR160E03X.

Same problem: I can't see my Toshiba PH3100U-EXB (Gen 2) external hard drive when I plug it in. After awhile I get this error message (see attachment): USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. FOr assistance in solving this problem, click this message."
When I click it, I get a list of USB ports and devices, with Unknown Device in bold face. No real information there.
Yes, I ran Disk Management and the Toshiba did not show up when I plugged it in and hit Refresh.
Does it make a difference that the last time I used the external hard drive, we were in Windows XP and now we're in Windows 7?
Please help! It's not just the backing up I'm worried about...it's being able to retrieve files later!
Thanks!

Iomega external hard drive either 'not found' by Time Machine or is now in 'read only' format

I don't know what's going on with my iomega external hard drive. Sometimes the HD is recognised by the computer; other times it isn't; if it isn't I can restore to an earlier back up via Time Machine app; but it's like the disk isn't writable.
Ten days ago, I had trouble backing up my iMac using Time Machine. After turning it off and restarting my external hard drive, it backed up successfully.
However, today I am trying to back up my files, and TM tells me it can't find the external hard drive. Nothing has changed -- I have been out of town this past week -- but somehow my HD now seems to be in 'read only' format. It does turn on, and I could restore my computer to an earlier back up.
"Mac OS X can't repair the disk. You can still open or copy files on the disk, but you can't save changes to files on the disk. Back up the disk and reformat it as soon as you can."
Annoyingly, despite my HD not showing in Finder or on my Desktop (as it usually does), when I simply turn it off I get that warning message "The disk was not ejected properly".
Have tried verifying and repairing using Disk Utility, to no avail.
Am prompted to reformat but I don't have a good understanding of what this means and how to do it. I'm guessing this would wipe the disk clean and I'd have to create the initial back up image all over again -- I'm reluctant to do this since this HD is my only back up and if it all goes tits up I'll be up that famous creek without a paddle.
Thoughts, suggestions, input all welcome and deeply appreciated -- thank you!

It's possible a heavy-duty 3rd-party disk repair app can fix it, but they're expensive (DiskWarrior is about $100), and there's no guarantee it can do it.

That will erase it. See Time Machine - Frequently Asked Question #5.
It sounds very much like the disk is beginning to fail, although it's possible there's a bad port, cable, connection or power supply (if it has its own).
I'd suggest getting a new one, and using it for your Time Machine backups; once you have a good backup there, reformat the old one (and select Security Options to write zeros to the whole drive -- if that fails, you know the drive is toast). Use it for secondary backups, per FAQ #27. If it has failed, get a second new one for secondary backups.

Back up using time machine and external hard drive

Hello,
I am having a difficult time deciding the best way to back up important documents.
I have:
1TB internal hard drive
3 TB external hard drive and
1TB external hard drive
I currently have about 1TB worth of data to be stored, but that will increase to about 1.5TB once I get a bunch of stuff off the HD camera's hard drive. I would like to keep my internal hard drive somewhat free to keep the computer running fast, but also want to make sure I am properly backed up.
Should I put ALL (or nearly all) of the files on the 3 TB external hard drive, and have time machine back that up and not worry about the rest? I'm a little weary about putting all of the files on one device even if it is backed up by TM.
If I do this, do I need to back up the 3 TB external drive in addition to using TM?
Thanks!

How can I use one external hard drive for both Time Machine and iPhoto Library?

I have been using a 1 TG LaCie external hard drive for Time Machine backups. My (older) Mac has 160 GB and is almost full. I would like to move my iPhoto Library to the external hard drive, but I've heard Time Machine doesn't share one space well. Should I
1. create another partition (but will this erase what I've already saved) with Disk Utility? *I am running Snow Leopard*
2. create another volume to use for iPhoto, and if so, should the two volumes be of equal size?
3. leave it with one partition and move the iPhoto Library to the same partition with Time Machine back ups?
I know I don't need the entire 1 TG for back up of 160 GBs. Please advise the best path to take. Thank you!

You are getting incorrect information from your ASP. If you look at drive specifications the heat generated is no different for high vs low capacity drives.
I have upgraded the internal drive in my iMac 2007 with a 3TB Hitachi drive without any heat issues or other problems.
Larger hard drives have higher density platters so to access any given amount data the drives travel a shorter distance. Higher capacity drives should therefore run cooler than lower density drives because the drive spends less time spinning to access data.

I need to delete a lot of duplicates on iPhoto. I just bought my MacBook Pro and was so excited I downloaded my external hard drive without thinking through the process. I now realize I had my photos doubled up. So I actually have the same library twice.

Hello All!
I am so excited about my new computer and I didn't know that my external hard drive had so many pictures duplicated on it. So I downloaded the entire hard drive. I thought iPhoto was going to be my answer, and now after reading a lot of discussions, it seems I have royally screwed up. Please help me fix this problem. I am a computer novice. An even more Mac novice. I need very simple directions. I would just start over with iPhoto, but I downloaded my digital camera with brand new photos on iPhoto and also downloaded my digital camera software on my new MacBookPro. I am afraid if I "start over" with iPhoto I will lose my digital camera pictures. I bought the Mac to finally get my pictures straight, and look at the mess I have made. I had AVG PC cleanup and used that program last night to delete duplicates from my PC. I also used it to delete duplicates from my external hard drive. I omega. I know, I know, too late huh? But I am teachable. And I now have my external hard drive fixed. But now, my question to the community is how to fix my new Mac, and my iPhoto.
Thanks,

When you say to remove the photos out of the iPhoto folder, then import the clean single copies, I am understanding that the "original" file that the decloner was run against is now the "clean" single copies?
Ok, you've got iPhoto Library that you have imported everything into, you can't delete the iPhoto Library and start over because you have only one copy of some pictures in there, combined with a lot of duplicates.
You want all the duplicates out, but it will take you ages to do it by hand.
What you do is.
1: Right click on the iPhoto Library and "Show Package Contents"
2: You will see a folder called Originals, these are all your original photo's, copy this folder to a external drive someplace, it's your backup.
3: Select the Originals folder again and from the Finder Menu > File > Duplicate.
4: Now you will have a OriginalsCopy folder, move that OriginalsCopy folder onto the desktop area out of the iPhoto Library folder. Close the iPhoto Library folder/window.
5: Download the Decloner software and install it, use it to find all the "real" duplicates, via it's content on the OriginalsCopy folder.
6: From the Finder menu > New Folder, now send the duplicate files to that folder, so all that is left in the OriginalsCopy folder is 1 copy of your pictures, minus all the duplicates which are now in New Folder.
7: Open iPhoto and remove all your pictures in there. The iPhoto Library will update to become empty.
8: Now import the pictures from the OriginalsCopy folder, these will now have only one copy of each picture.
9: Open your New Folder, from the Edit menu > Select All and
10 From the Finder > File Menu > Open With > Preview.
Now you have one copy in your iPhoto Library and the duplicates in a New Folder opened with Preview which you can compare to make sure.
Make as many backups of your pictures as you think you need during this prcess, but eventually you only want 1 picture of all you have in the iPhoto Library.
Some pictures may be the same thing but a little smaller etc., these obviously are not duplicates, and you can weed those out by hand in iPhoto.
Good Luck.

IPod cannot be synced because external hard drive could not be read

I moved my music folder to an external hard drive to create space on my laptop, and changed the location under Preferences / Advanced. Since I did this, my iPod trys to automatically sync but gives the error message "The iPoD "[name]" cannot be synced. The disk could not be read from or written to." The external hard drive is on and working. Is there some reason that the iPod will not sync with this external hard drive? What do I need to do to fix it? Thanks, Bill

First question, since you made
the change, can you still play your music from within
iTunes?
Patrick
Sorry for the delay in answering as I have been traveling. Yes, I can play music from iTunes. The music is located on my external hard drive. iTunes software is on my laptop, and the music library points to the music folder on my external hard drive.
Thanks, Bill

My external hard drive is no longer recognized by my Mac

I have used Time Machine and a WD external hard drive to back up my computer for several years. Now, when I connect the hard drive, the drive lights up as though it's working, but the connection does not appear on my Mac -- the external hard drive is not listed in Device (in Finder). Any suggestions?

power feed issues and data appearance/disappearance are both symptoms of the SATA bridge card,..arguably the most failing modern computer component made.
throwing more power to the drive wont fix that.
SATA bridge card as found inside all USB HD devices which has an extremely high failure rate.
Inside a USB hard drive, containing the HD and SATA card
Countless 1000s of good external hard drives are thrown away each year because the owner thought the HD was bad when it fact it was the SATA bridge card which had failed. This card is removed in a matter of mere second once an external USB HD is cracked open from its plastic casing to reveal the bare HD and the attached SATA card which attaches between the HD and the USB cable.
quick and easy option is to crack open the WD USB drive, and remove the SATA card, and put the WD drive into a new enclosure ($20)
HOWEVER, if its an OLD WD drive, the SATA interface is permanently attached to the HD and the OP is "out of luck".

My WD external hard drive is no longer show up on my computer-it no longer recognizes it.

I have a WD external hard drive for sometime that I have been using to backup my computer and generally keep some of my bigger things on it(such as degital copies of movies). But suddenly one day my computer won't recognize my external hard drive when I went to plug it in. The light on it that is on when it is plugged in is on when I do plug it in, yet I can't actually find and acess my external hard drive. I don't know whats wrong and how to fix it so I can continue using my hard drive.

dead sata bridge card. very common problem.
see all about it here:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
verify HD on another Mac however, if same, dead SATA card most likely

I have moved all my songs onto a new external hard drive but it has wiped my iPod clean. Although when I connect my iPod it's starts teh process of sync'ing - so many songs in I get a pop up advising the siong could not be read or written to?

I have moved all my itunes onto a new external hard drive to free up space. It has wiped my ipod clean! I can still see the itunes on the new hard drive so I restored my iPod and tried to sync. Although when I connect my iPod it's in the process of syncing, so many songs in I get a pop up saying could not copy to my iPod as xyz song title could not be read or written. I click ok for this pop up to dissapear and then another pop up appears saying could not coyp to iPod because of unknown error.!!! Help I'm going crazy.

Did you go into iTunes to change the location of your media files? if not you will need to go into iTunes and click on preference and select the advance tab then click the iTunes Media folder location. Select the location of your on external hard drive.

PSE 8 - Archive on external hard drive including captions and tags

I started my above discussion some time ago with Mark and due to the lateness in my responding the case appears to have been closed. However I am hoping that someone can comment on my intended course of action, see below, based on his suggestions?
Just recapping having successfully migrated my Photoshop Album 2 catalog including captions across to PSE 8 and now my objective is to move my entire PSE 8 catalog to an external hard drive leaving only thumbnail view to remain. Obviously I am anxious to avoid any catastrophe and therefore would appreciate comment on the correctness of the steps involved. I have arrived at these by simply modifying Mark's original steps. Please correct where necessary.
1) Connect my external hard drive where I want to copy the files too. Make sure I can 'see' it in Explorer
2) Open Photoshop Elements 8; click the Organize button on the Welcome screen
3) Displayed in my welcome screen is my entire catalog with each album matching in title and file (photo) content to the folder title and file (photo) content in the folder location displayed to the left of screen.
4) Go to the File menu, and select 'Write Keyboard Tag and Propertise Info to Photo'. In my case most but not all files (photos only) will have tag and caption data. Rather than attempting to select the files that I wish to embed tag and caption metadata does Organiser have a global 'search and embed instruction' so that when it gets a 'match' on .jpg number it will embed automatically?
5) After completion, I go to the File menu, and select 'Copy/Move to Removable Disk...' click the MOVE button to move the files from their current location to my nominated external hard drive.
6) Click the Next button, and select the external drive in order to copy the files to the drive.
Can you confirm?
* On completion of the above steps my external hard drive will allow access to full resolution versions of the file from Photoshop Elements including any existing caption or tag data organised identically to my PSE 8 catalog (only one catalog)?
* Am I correct in assuming that also all original photos from my laptop will be removed and if not can be deleted given their existence on my external hard drive?
* Is the data which now resides on the external hard drive capable of being read on any other PC which may not have Elements software?

I have 2 laptops an aging Dell and new HP. I have successfully followed your
instruction and deleted 1 & 2 below on both.
The Dell PSE 8 now has:
C:\Program Files\Adobe\PSE 8 (240Mb)
C:\Program Files\Adobe\Elements Organizer 8.0 (502Mb)
C:\Program Files\Adobe\PhotoshopElements_8_WWEFDJ.EXE (1.17Gb)
C:\Program Files\Adobe\ PhotoshopElements_8_WWEFDJ.7Z (1.06Gb)
Giving a total of 2,972Gb
The HP PSE 8 has:
C:\Program Files\Adobe\PSE 8 (240Mb)
C:\Program Files\Adobe\Elements Organizer 8.0 (502Mb)
C:\Program Files\Adobe\PhotoshopElements_8_WWEFDJ.EXE (1.17Gb)
C:\Program Files\Adobe\ PhotoshopElements_8_WWEFDJ.7Z (1.06Gb)
But a total of 3,894 and I am unable to identify where the additional 1Gb
resides. In Documents & Settings\All Users\Application Data\Adobe\Elements
Organizer is 120Mb. I have attempted to delete this but lost the catalog in
the process so had to restore from the Recycle bin and it now appears to
have reconnected correctly. Frankly I can live with these large file sizes
but would like an opinion on their potential adverse impact at sometime in
the future.
I am not sure whether I need to start a new thread for "Are there any known
bugs in PSE 8 surrounding the burning of discs" I have attempted to burn
onto a new CD-RW my slideshow. The process of burning appeared to work but
the written to CD does not play on the DVD. I have also saved the slideshow
as a PDF. I can't recall exactly how but in selecting an incorrect option I
no longer have visibility of projects in 'Folder View'. The projects are a
single slideshow and PDF copy of the same. How do I regain visibility?

HP SimpleSave External Hard Drive - Can't Access Files, Says to Re-Format

I have had a SimpleSave External Hard Drive for over a year now, and have never had any problems with it.
Recently, I am unable to access my files on the hard drive when it is attached to my computer. It tries to load, and then gives me the error message "You need to format the disk in drive H: before you can use it. Do you want to format it?". I don't want to format it because I don't want to lose all of the files that I have stored. When I press "Cancel" i also get the error message "H:\ is not accessible. Data error (cyclic redundancy check).
I have not changed anything recently so I do not understand why it has all of a sudden stopped working.
I am using an HP notebook (G62 Notebook PC) and Windows 7 Home Premium operating system.
I am connected to the hard drive via USB. I have tried turning off my computer and turning it back on, and unplugging the drive. I have tried using other USB outlets.
My SimpleSave information: model no hp md1000h
P/N HPBAAD0010HBK-00
The blue light is still blinking on the front of the hard drive.
I would like to access my files and get the external hard drive working properly again. Please help!
Thanks in advance!

I too have the exact same problem on my HP SimpleSave (sd500a) external hard drive. I got through to WDC, and they apparently support these devices now. They asked me to send them a copy of my purchase receipt in order to extend my warranty in their system in order to help me (ridiculous!!). I sent the scanned copy of the receipt to [email protected], and got an auto-reply that they will get back to me within 1 day. I also went on their website, and they refer to the device in their system as 'ED Caviar Blue EIDE Hard Drive'. It has the same serial number as my product from HP, so I guess they have acquired these products or at least support of them (?). In any case, I'm freaking out because I have tons of family pictures, video and my entire iTunes library on the device. If any one is able to get help for this, please respond. I am desperate to get this resolved.

External hard drive gone kaput

I have an old Mac mini (1.42 GH PowerPC G4, Mac OS X 10.4.11) with an 80 gig internal startup HD, and an external 250 gig Firewire HD. For the last couple of days, the external HD has not been getting recognized by the Mac. When I run Disk First Aid, the drive shows up, but the disc itself - "disc2s10" - is greyed out. When I run "Verify Disk", and subsequently "Repair Disk", I get the following response:
"Checking HFS Plus volume
Invalid node structure
Invalid node structure
Catalog file entry not found for extent
Volume check failed
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error"
I've tried everything - power on, power off, disconnecting and reconnecting every cable both on the Mac and on the external HD, but nothing seems to work.
I tried looking at solutions in the Apple Support section, but frankly, I've not had much success and am not even sure whether I did the right things.
Losing the disc would be a disaster - not least because I've painstakingly organized 18,000 songs in my iTunes library, and those songs are all stored on the spoilt HD!
The only other thing I can add is that the disk went bad after I Installed the latest Apple security update a few days ago. I don't know whether that had anything to do with this.
Finally, I've had some problems in the past with this HD - which is housed in a casing that has the same form factor as the Mac mini - in that it sometimes did not mount. But I believe that has been due to some loose internal connections between the disk and the casing. At any rate, that has not been a major problem.
Clearly, since the Mac mini says the disc is unreadable, it can "see" the disc.
Could somebody please help? Thanx.

Error: The underlying task reported failure on exit
When you get this message, does is also show a -9972 error number? If so, the Apple disk utility can't repair the drive. As Boece recommended, Disk Warrior, or similar, program would be your next step, and it can often repair what Disk Utility can't repair. However, if Disk Warrior can't repair it, then you want to look at other software to try and recover the data, as the next step would be an erase and restore. And if that didn't work, then the drive is toast. There are services that can recover the data off a dead drive, however, they are not inexpensive.
Some other thoughts ... can you open the hard drive case and pull the short cable off the hard drive and put it back on? Make a difference? Do you have another mac available to you that you could hook your external hard drive up to? Just to see if there's any difference in accessing it? Is it only a USB connection or can you also connect via firewire?
