My C665 S5046 no longer recognizes the hard drive

I booted up my toshiba C665 S5046 and it goes to a screen stating I need to use a boot disk? Any idea what happened or what can I do as a work around? Does this mean the hard drive is bad?

DaddyPaycheck, thankyou for the reply. It appears there might be some physical damage which worries me. But what perplexis me is that the drive receives power... it takes the disk (won't eject it.. even on restart, but it takes the disc), and when I boot into open firmware, I get "unable to eject the drive volume"... or something like that... The point being that it appears to believe that there is a drive, but doesn't know what to do with it.
That being said...it still won't recognize in the ATA of the system profiler.

Macbook No Longer Recognizes External Hard Drive

Recently I bought an external hard drive (Toshiba Automatic Backup Portable Hard Drive) to backup my Macbook (Mac OS X 10.6.8). I found that in order to have my Mac recognize the hard drive, I needed to partition it by formating it to MS-DOS (FAT). I had no problems after that and began to back up my computer. However, the next day, I plugged my external hard drive back in and the icon no longer shows up. I went to Disk Utilities and found it there, but it said that it was not mounted. Then I went to System Profiler to see if it was under "USB" but it did not show up. I have tried shutting down and restarting my computer a few times but each time is no different. I even added a USB 2.0 Hub but even that didn't work. Is there anything else that I could do? I have files already on there and some I do not really want to lose. Is there any uncomplicated way that I could be able to make my mac recognize my hard drive again?

ellybook7,
In OS X you can read from an NTFS disk but not write to it - at least not without thrid-party software such as Paragon's NTFS for Mac.
I'm not sure what was working FINE in Mountain Lion that wouldn't work in Mavericks.

So I formatted a brand new hard drive to MAC OS (Journal), I then could save on the hard drive. Not two days later Im back at square one, the program wont recognize the hard drive again.

So, hard to beleive, but I am having some trouble with Final Cut Pro X.
This last week I formatted a brand new hard drive to MAC OS (Journal),
so that I could save on that hard drive.
Well it went great.
I saved my project on there and copied a few others over as to free up space on my Laptop.
Then, not two days later Im back at square one,
the program wont recognize the hard drive.
It wont even open the events up off my hard drive,
as to jog the program into reqcognizing the scratch disk (which worked twice before).
What happened?
How do I get the program to re-recongize my newly formatted hard drive?
Please help!

The name of the drive, or the name of some folders inside the drive, may fool FCP X into believing it is a camera.
Also, you should not use the drive for time machine backups.

I have iMovie 09. I just erased my external hard drive, but it is still formatted for the mac. However, iMovie will not recognize the hard drive. It shows the only hard drive available is the computers. How do I get the external hard drive to show up?

In Finder's Menu, select Go menu>Go to Folder, and go to "/volumes". (no quotes)
Volumes is where an alias to your hard drive ("/" at boot) is placed at startup, and where all the "mount points" for auxiliary drives are created for you to access them. This folder is normally hidden from view.
Drives with an extra 1 on the end have a side-effect of mounting a drive with the same name as the system already think exists. Try trashing the duplicates with a 1 or 2 if there are no real files in them, and reboot.
If it does contain data...

Macbook pro no longer recognizes external hard drive

Hi everyone,
My Macbook Pro (2013) running OS X 10.8.5 will no longer recognize my external hard drive.
The hard drive, a Maxtor OneTouch 4, is granted quite old (c. 5 years) but has been working fine with my Macbook pro since I bought it 2 years ago. It is too full to do time machine backups but I just need to get some files off of it. It doesn't appear in Finder or in Disk Utility when connected and turned on.
Since it's only stopped working recently I suspect some software update may have rendered it obsolete. I have also noticed some glitchiness with my USB ports, but some things work fine.
If anyone has any suggestions of what to try, I would really appreciate it! I really need to access those files.
Thanks very much in advance!

T60 hard drive replacement - Windows does not recognize the hard drive

Hello All, new to the Lenovo Community. I have a T60 as well as newer Lenovo Edge. The HD crashed on the T60 and it will no longer boot. I just purchased a WD 500GB without doing a lot of research. In trying to install Windows 7 (I had already upgraded the T60) it will not recognize the new drive - Windows does not see the drive at all. Is there a way to get the Lenovo to recognize the WD drive? Thank you in advance for any help.
Solved!

Glad I was able to help.
Just be careful, the usual "if it doesn't fit, find a bigger hammer" doesn't apply to this model laptop.
Also, there is a part available to adjust the frustration level, I don't happen to have the FRU number available, but I do have a photo and I'm sure you can find a local shop to provide it. Any experienced vendor should be able to match up a similar item from this photo.
It comes in many varieties, this model has a handy extention to aid in installation so you can easily do it with one hand. Others may require two hands to safely install. Use care when installing, one slip can destroy your laptop. Acute abuse can lead to severe embarassing situations and cronic abuse can have impact on your health, so use wisely and always get a spare to share with a friend. They tend ot come conviently packaged in quantity of 6, so you can invite a few friends over.

MacBook Pro can no longer see the hard drive

I've got a MacBook Pro Core 2 Duo, 15-inch.
Okay, so I was chasing the nazis out of North Africa in Call of Duty 2 when the game froze. Command-Option-Escape was unresponsive, so I held down the power button to shut the whole thing down. When I brought it back up, I got the flashing folder icon.
After yelling a few words I shan't repeat here, I booted off the installation DVD, then started up Disk Utility to try to repair the disk. However, Disk Utility only sees the DVD; it doesn't see the hard drive at all. Neither does Startup Disk or System Profiler. (The hard drive would be under the ATA section in System Profiler's menu, right? It only shows the DVD drive.) If I try to go ahead with the OS X installation, at the "Select a Destination" screen, where the list of disks should be is disturbingly blank. So according to every method I've tried so far, it's as if my hard drive has been entirely disconnected.
This was my Christmas present, and I was hoping to get at least two years out of it, not two weeks. Anyone have any idea how to get this beautiful machine back on its feet again? I'm familiar with Unix and not afraid of using the command line, but I'm not sure what to try there.

Imac no longer recognizes external hard drive

my iMac no longer recognizes my external hard drive. An icon used to be on my desktop, at times it would disappear and come back, but it has remained elusive for the past couple of months and is NOWHERE to be found. It doesn't even show up in the Disk Utiity. I need my files!

Please Google, "Intel iMac SMC Reset" and follow the instructions. If the drive is OK this may solve it.

NB200 -00L stopped during the middle of formatting, can no longer use the hard drive recovery option

Hello,
NB200 -00L is the model
Power was down during the beginning of hard drive reformat,I had tried to press 0 (zero) during restart
I had also tried to press F8 during it restart, then choose repair option, but it kept rebooting itself in a loop with no error message.
I really would like to restore to the manufacturing settings.
I had my usb drive, but the system does not recognize the mirror image on my usb flash drive anymore.
Unfortunately, my model does not come with a dvd reader neither.
What are my options?

Netbook NB200-00L (PLL28C-00L011)
Everything for that Canadian model is here.
the system does not recognize the mirror image on my usb flash drive anymore.
I don't understand what's happening. If you cannot boot from a flash drive with recovery media, it may be that the drive does not have the proper contents. You can remedy that by ordering a new flash drive from Toshiba.
See the section Restoring the pre-installed software from your created Recovery Media, which is on p. 3-14 of your User's Manual.
If you cannot boot from a known bootable flash drive, I would seek service.

IMac G5 no longer recognizes external hard drive

I have a Western Digital 250GB external USB drive. Yesterday, my G5 no longer recognizes it. I've restarted the computer, restarted the drive, unplugged and replugged the USB cord etc...
It's like it no longer exists ! Please help

Does the drive turn on? Is the power brick working? Have you tried plugging it into another computer or another USB port? I know you have plugged and unplugged it, but do it several times in a row. Unplug, turn it off, plug it in, turn it on and unplug etc etc, repeat the sequence several times.
BTW, is it an iMac you have, or a G5 tower?

Lion no longer recognizes external hard drive.

I've had Lion since the first day it was out. All of a sudden, as of Sunday July 31, it is no longer recognizing my external hard drive, prevoiusly used for time machine. I can see the disk in disk utility (disk repair does not fix the issure); however, it does not show up in the finder. Anyone know how to fix this?

Since you haven't provided any helpful information all I can suggest is this:
Open Disk Utility in the Utilities folder. If the drive does not appear in DU's sidebar listing, then it most likely has died and needs to be replaced. Take it into Apple for service.

DV8000 Hard drive issue - wont recognize the hard drives

This is my first post so please let me know if I do anything wrong!
Ok so the other day I was working on my dv8000 when it just powered down. I turned it back on and instead of booting properly it told me that it could not find the operating system. Knowing that the machine had two drives in it, I swapped the primary with the secondary and still got the same result. I then went out and bought an external drive bay and attached the primary hard drive to my desktop. The drive was bad and kept cycling the heads. I have now bought a brand new hard drive and the laptop is currently configued with the new drive in the primary slot and the other original hard dirve that I checked and is good in the second slot. Here is my problem - when I go into the bios the computer recognizes the two hard drives for boot options but when I try to load XP from a cd to the laptop, it tells me that there are no hard drives installed... what am I missing? I have checked the drive for errors via the bios and the test come back passed. I thought about formating the drives but the the bios does not have a format feature in it that I can tell. for all intense and purposes, the bios sees the drives but the operating system does not. Any ideas>
Please help as this is my business machine and I cant keep borrowing my wifes laptop, she thinks I am gonna break that one too!
Thank you.
This question was solved.
View Solution.

That did it! I had to turn off the Native Sata Drive support in the Bios! now the machine is up and running. HP has told me that I need to purchase a replacement drive from them as the replacement drive that I bought from my local store does not have the HP restore partition on it. I can still access the original drive and I do see that it does still have the HP restore partition on it. is there a way to just create a partition on the new drive and copy the files across?

My iMac doesn't recognize the hard drive

Hi all. I have a question. I have a iMac G5 20" 2Ghz and I'm trying to instal a replacement hard drive. It's a WD 320GB HD with wite and blue stiker (It's a WD Caviar Blue). I'm trying to instal MAC OSX 10.5 it a retail full version DVD and when I get to the screen to select drive it doesn't see it. I went to Disc Utility and looks like it show the disc but there is no information. All I could get it is:
S.M.A.R.T status - not suported
Partition Map Sheme - Unformated
Total capacity _ 0 bytes
Please help. Thanks

Try reformatting the drive as Mac OS extended (journaled) and see if that works.
What do you mean by "foreclosure"?

At the urging of an Apple Store employee, I upgraded to OS Lion X. However, Excel does not recognize the hard drive and I cannot save any work. I understand there is a small compatibility issue - any suggestions ?

I need some direction on fixing an issue with excel and lion x which has a compatibility issue - can't save my work to a hard drive.

If you made a backup before installing lion, now would be a good time to restore that backup.... Ok, well you can always boot into lion recovery menu.... shut down your mac, hold down the option key and restart your computer..... Select recovery from the disk startup menu and go to disk utility... select the OSX disk, you can try repairing your permissions and repairing the disk.... If you lucky enough, it will fix it.... If not, and you have a decent internet connection, click the reinstall LION OSX after exiting disk utility. Your mac will now REDOWNLOAD LION OSX and reinstall it.... did you happen to make a backup before?
Also, did your mac originally have Leopard? Just curious... Because LION is entirely 64bit now where as Snow leopard had support for 32 bit as well, but the problem may be that some of your older apps where 32 bit.... This is just a guess though I'm not sure.... Because I've had numerous problems and crashes with my CS 4 stuff and final cut pro 7 and aperature.... Not sure if it's totally related to the whole 64 bit thing, but the thing is that the crashes are only occuring on my 32 bit apps.... otherwise the computer runs great.... To remedy, I had previously made an OSX lion USB drive so that I could do a fresh install of LION. I backed up all my data and files, installed a new SSD and my Macbook is SCREAAAAAAMING fast.... Sorry about the gloating but I'm sure we'll get to the bottom of your problem....
