Toshiba 1TB External Hardrive not recognized after using a USB 8GB Drive

Hello.
Windows 7 Ultimate, HP G671 Notebook, X86 based PC, Bios HP F, 20 10/13/2009, Intel Core 2Duo CPU [email protected] GHz, SMbios Version 2.4.
The Toshiba ext. HD was recognized initially but after the second time I needed to plug it back in there was no recognition in the drives list, under removable storage. I find it listed in the devices where it states that it is enabled and working OK. Also I see it in the computer management/disk management area as healthy. However, I obviouly cannot change files. I just noticed that there is no storage amount listed with the C:: Native Drive, nor in the D: disk drive when I have a DVD in it. I've reassigned letters to the external drives and done the powereing on/off rebooting suggestions without resolution. Any advice?

Nobody?

Hi
Is there any specific error message when you plug in your external HDD?
May I know when you upgrade OS to 8.1, this external HDD still attached?
So before your upgrade your OS, this external HDD working fine?
Did you try to attached your external HDD to another PC or laptop?
did you check inside device manager whether your external HDD detected?
may I know the details your external HDD spec and PC spec?
Please provide as much as information that related to this issue

ATP Photo Finder GPS not recognized on Mac as USB flash drive

Much like the problem with the Sony GPS-CS1, it appears the ATP Photo Finder device also will not be recognized as a flash drive on a Mac. Tiger worked with the Sony for awhile, but recent updates (as well as Leopard 10.5.x) have made it no longer work. There are other topics on the GPS-CS1 in these forums detailing those problems.
I picked up an ATP Photo Finder from My Discount Digital to try it out. It logs data, then you insert the memory card in to the device and it will GPS stamp the JPGs. It sounds like a great idea, but when it didn't work I was going to have to plug it up to my Mac and use PC software via Parallels to reprocess the images.
It is not recognized -- and under Parallels, a new USB device shows up simply listed as "U" under the pull-down menu. When I try to select it, it claims it is already in use. Methinks Apple Mac OS X is semi-grabbing the device but not being able to use it.
Odd.
So I post this in case others have the ATP Photo Finder and have problems... Maybe we can figure something out.

Well, here's an odd (and quick) self follow-up... I was reading an Apple Help file and it suggested looking at the System Profiler to see if the device is being recognized. Indeed, it showed the "U" and some garbled characters (so something is not quite right). It also showed it was plugged in through my powered USB hub. I bought this hub after running in to issues with devices that would not work plugged in to the iMac keyboard... On a whim, I plugged the ATP Photo Finder in to the non-powered USB port on the keyboard and ... it worked. It still shows up as U(garbled) but I was able to access it from the Mac Finder.
Interesting.

Welcome to Mac-land.
This wouldn't happen to be a WD external drive, would it?
Is there some utility on your Windows laptop that you can use to repair the external drive? Something equivalent to Disk Utility on a Mac? I'm not a Windows guy so I don't know.
If the data is still on your Windows laptop, then maybe your Windows machine can erase the drive enough for you to get it to mount on your Mac.
Another option might be to see if your Mac will boot into recovery mode (restart and hold down ⌘R until you see the Apple logo), and then maybe Disk Utility (you'll find it when you boot into Recovery Mode) would be able to see the external drive and either repair it or reformat (erase) it.
Occasionally Techtool Pro 7 will be able to repair something that Disk Utility can't. Techtool is a good thing to have; it's the only third party maintenance/repair utility that you need. Techtool installs a repair partition (the eDrive) on your internal hard drive, similar to the recovery partition that is already there with Mavericks. So you might be able to boot into the eDrive and then see the external drive and either repair it or format (erase) it so it will show up under normal boot conditions on your Mac.
It seems less likely, but perhaps your external drive has chosen this time to die. If you can't get it to mount/erase/repair with either machine then that's probably what's going on.
Less likely than that, but still possible, is that the problem is with the external is in the enclosure itself, and not in the drive within, so if you can't get it to work any other way, it's worth a shot to remove the drive and put it in a different enclosure and see if it will work.

External HDD not recognized after Finder Crash?

Hi guys. I was loading a file in photoshop from my external hard drive. It was a big file 1.5gb. After 10 minutes of waiting i decided to force quit Photoshop as it was frozen at the loading bar. Soon after the finder stopped working too, so i restarted my mac.
Now everthing work fine but my external hdd its not recognised anymore. It works, as i can see the light on, but doesn't show anywhere on my mac.
I have tried on a pc as well and the same result.

Any help would be much appreciated

External HD not recognized after incorrect ejection.

I recently unplugged my external HD from power while it was plugged in to my MacBook, though my MacBook was closed. When I opened my MacBook, I was informed that the drive was incorrectly ejected. Now, my computer refuses to recognize the drive. I have plugged it in to both of my USB ports and tried restarting my computer. Help please!

Not sure how this question relates to an AirPort Express, AirPort Extreme or Time Capsule, but try the following basic troubleshooting steps:
Power off the entire network....all devices....in any order you want
Wait a few minutes
Start the modem first and let it run a full minute by itself
Start the router next the same way
Start the Mac next the same way
Start the hard drive next the same way
Start other devices one at a time the same way
See if the Mac can see the hard drive
If no help, contact support at the drive manufacturer for additional assistance.

External HD not recognized after Formatting & Running time Machine.

Hi All, Hope someone can help me out here! Last night, I plugged in a Seagate external hard drive via USB, and my mac recognized it and asked if i wanted to treat it as bkup for time machine. I selected "yes", formatted the HD, then it had a status bar going for a few hours where it transfered information, then hours later the status bar disappeared.
Afterwards, I clicked on the ext hd icon, and the entire computer froze up. Upon re-booting, the ext hd was still plugged in, but wasn't recognized at all by the mac. I tried turning on/off the hard drive, different USB ports, etc., but nothing. HELP!!!

Sounds like you might have a failed External HD. Does Disk Utility see the HD? If it does, try mounting the disk then reformatting.
BTW, you should really post this to the Time Machine Forum. There are more experts there about Time Machine.

External disk not recognized after lateset mavericks update

Just updated my MacBook pro Retina to 10.9.5
since then, my external hd WD My passport Ultra does not mount on the finder. It is visible in Disk Utilty, but is greyed.
ANy suggestions?
Thanks

the WD ext disk has just appeared on desktop and did the usual back-up process...
Yesterday I checked it several times and disk utility even told me that the ext disk should be repaired, which it failed to do...
now it is working again. (must have just needed a good night's sleep...)
Should I still be worried? Any comments, please?

IPad not recognized after disconnecting from USB

I have and iPad 2 and just upgraded to iTunes 11. I can connect to my iMac (using snow leaopard OS) through USB and the iPad will show up as a device in iTunes. However, as soon as I discunnect my USB connection the iPad is no longer listed as a device (it used to remain listed for wireless connection). Accordingly, I can not wirelessly sync with iTunes and my automatic backup when I plug the iPad into an electric outlet no longer seems to work.
Are there any suggestions for trying to fix this?
Thanks.

I have a similar problem but have had it since the ios6 upgrade. Itunes used to be able to see my devices without connecting with a usb cord but can no longer do that. I hoped that Itunes 11 would sort out the problem but it has not. I am using a Windows 7 PC. I have tried various suggestions, such as connecting, syncing and then disconnecting, stopping Apple Mobile Device service and restarting, resetting router, shutting down Itunes and Ipad and restarting....nothing works. It is annoying! It would be great if someone could offer a solution!

External hardrive not workon on MacBook Pro

I own a Seagate FreeAgent GoFlex that is 1TB and have had it for about 3 or 4 years. I used to be able to plug it in and with ease insert files (pictures, music, documents, etc .. basically everything in case my MacBook stops functioning.)
Back in May, I took my external hardrive to my University before I graduated and I could not insert some video files (using another computer, which was a Mac.) Our school's tech expert said it was because my external hardrive is not applicable with Macs. Long story short, I showed him I can do it on my MacBook Pro, then I had to save my video files on a flash drive instead. Anyway.
I want to back up everything incase the MacBook stops working soon (it's six years old.) However, when I put in my external hardrive, I can't change the name of files/folders in the external hardrive nor can I insert anything into the hardrive. Oddly enough, I can drag stuff into my desktop and it will copy a file into my desktop while the same file still stays on my hardrive.
My MacBook Pro is Version 10.9.5 (if it matters) and I have more than 90 GB of free space on my MacBook and have nearly 700 GB of free space on my external hardrive and obviously I'd like to use that. Also, I'd like to use my external hardrive not just on Macs, but all machines in case I need to save large files. I used to be able to do this at one point, especially with a previously owned hardrive (it was Western Digital.)
Anyway, that's all the info. All help would be greatly appreciated.

I meant to also say that your school's tech expert does not appear to be much of an expert.

HT202274 Password change old password not recognized after 10.9.5 upgrade

God bless you, peace.
macbook pro 2012 user password not recognized after 10.9.4 too 10.9.5 upgrade plus tech work at apple.
I want to change user password, it is allowing me to get into user account and admin account on computer but I recently changed it for the tech work to be done. I would like to put the password back now to old password or a new one but... The few days old new password pre update and pre tech work is not being accepted to allow me to change to another password.
recent update, after 10.9.4 to 10.9.5 update and apple tech work done.
1. Tech work replaced optical drive,
2. 10.9.4 to 10.9.5 upgrade left computer endlessly booting up, then got into finder window tried to read backup drive and screen went to black curser and could not backup information as techs decided may need to be done before I left it with them.
3. Also track pad was not (is not again) selecting text to drag unless real hard press and then only intermittently would select text or just drop the selection (not hold the selected text after a long scroll select, did work at first after tech work but back to not working). It is still not responding easily when pressed, but it is much better, as they did something with software they said. Today While typing this I am trying to select words misspelled and it does not select them unless I press not as hard it is becoming the same as before I see now, sometimes less pressure is needed but more than should be used.
I noticed today after tech work The Spell check is not responding with a two finger tap on the red underlined misspelled words without multiple try's with two finger tap. The curser moves around after selecting words also, or when selecting words so hard the curser moves to another place not on the desired words or check box. The curser arrow tip should select the word but it does not recognize unless I put the tail of the arrow onto the word then it recognizes the misspelled word for spell check on two finger gesture.
It looks like I need to take it back, I tried to call and check to confirm if the track pad intermittently and curser adjustment was serviced. In order to verify I had called three times to get that information to no avail. endless looped in the phone que, one would answer take info and then forward me to a endless loop dial ing phone that never was picked up, supposedly at the Bay street store tech section. Phone voice mail from apple support status on the repair, ...Juliano from Bay Street Apple repair store Emeryville, ca left a voice message... just generically said optical drive replacement is successfulI, I noticed right away three items were to be addressed but only the optical drive was mentioned, so I called three times to try and verify the other problems. One whole minute just to select this text and copy it to notes for a backup. It would not select at first, then after selected it would not copy it, then it would not paste to notes, it paste the last cut and paste I did 10 minutes ago.
I do not have a easy excellent wifi connection for my wifi only phone and would prefer email or chat for repair help. apple Repair No: R142180337

Try running the combo update. It fixes more files/data than the App Store upgrade.
10.9.2

Logitech trackball not recognized after 10.5.8 update- LCC 3.1 needed

Logitech Trackman wireless trackball was not recognized after 10.5.8 upgrade. At re-boot, the "searching for bluetooth mouse" screen appeared, pushing the re-set button on the wireless base and trackball did not solve the problem.
Had to plug in my Apple mouse (worked immediately), go to the Logitech website and download the latest Logitech Control Center software for Snow Leopard, dated 9/22/09 (version 3.1)
After install and re-start, Logitech hardware worked perfectly, as before.
Not sure if it would avoid this issue, but I recommend installing LCC 3.1 before you install the 10.5.8 update. That or be sure you have an Apple mouse on hand.

Turns out the 10.5.8 update is missing a very important file which is

I have that file on my system and x11 was updated using 10.5.8 combo update. it works just fine.

Camera RAW, file not recognized after import and migration, Aperture 2.1

Hi,
I have recently purchased a 1DMKIII and am constantly getting "file not recognized" after I import and even after migrating RAW files. My 1DS MK1 RAW files have no issues. The RAW files render just fine using CS4 bridge. Any ideas here on a fix? Other than ditching Aperture (not desireable)
Thanks,
Greg

I shoot RAW and the iMac will not recognize the NEF RAW files! this is soo frustrating - tried to update Camera Raw but to no avail.
please help! I've got 987 raw wedding photos to process!!
I dont know what to do!

Overhead calculation not happening after using Overhead key and orgin group

overhead calculation not happening after using Overhead key and orgin group.
There was a runtime error earlier related to u201Cdefine credit u201C IMG node under costing sheet component and we have applied SAP note 769946 and that error was gone out of the way
We want to apply/add Overhead to SFG/FG materials.
We are using PP order with PCC(product cost collector) as the cost object , i.e costing by period.(system ECC 6)
But our problem is with material standard cost estimate process.
We have assigned overhead keys to the percentage rates in costing sheet for material standard costing and assigned the origin groups to the credits of costing sheet. But after running the cost estimate overhead is not taking into account for standard cost calculation.
In the define credit entry table key field is valid to date strangly and actually system should allow one than one entry with same valid to date and same sec.Cost element(type-41) for different cost centers.
But if we without using overhead key and origin group, the entire cost in that supporting cost center will come to all materials (SFG/FG) and we can not distinguish between different product materials(SFG /FG).
We have checked all things as mentined below.
Firstly that the correct costing sheet is assigned to the valuation
variant.
That the costing sheet is entered for the appropriate material type:
Finished and semi finished or material components.
All of the above can be checked and verified via transaction OKKN.
In addition make sure that the base value maintained is present in the
costing, for example the base may include an Origin group, is that
origin group part of the materials being costed?
Similarly if the base is found and values exist how is the overhead
rate of the costing sheet set up, is it valid etc.
And finally do a similar check for the credit.
we doubt this as a programm error...
So, request all experts to have ur feedback..

Dear,
Check your origin group & material unit of mesaurement is same.
some time in costing sheet origin group is maintain in different unit & for materail it's maitain in other unit of mesaurement.
You can see unit of measure for material in Additional data - unit of measure.
Check BOM component material unit also.
Check same unit of measure is maintain in KZS2
I hope above will useful.
