T410 cannot recognize any esata external enclosure

Hi , after reading a hundreds of posts and advices, I decided to look for a lest help on this forum. My T410 with Windows 7 cannot recognize any of my 2 disks mounted in external enclosures.Disks are good, they work perfectly as internal drives. I've tried already 3 boxes from 3 different esata box vendors. All of them behave in the same way: T410's BIOS can see them in its Booting list, but Device manager nor Disk manager cannot detect them in W7. The newest drivers are in place. The disks are powered via USB port. Still no success. Any advice appreciated.

Hi
Did you notice any yellow exclamation marks in the device manager near the USB host controllers?
Check this!
Even if the yellow exclamation marks are not visible in the device manager I recommend removing the USB host controllers and USB root hubs from device manager and to restart the notebook again.
Wait until all USB controllers will be recognized by Windows and test your external USB devices again.
Bye

Cannot recognize any internal hard drives, hard drives good

Hi,
My macbook pro 13" (bought in august 09) recently stopped being able to recognize its internal drive. I've run it through all sorts of diagnostic software, but none has been able to recognize it at all.
I've tried swapping out the hard drive to one that is brand new, but it still cannot recognize it. Everything is physically connected as it should be, and I'm running out of ideas for what to try.
I do not have easy access to an apple store to bring it in. If it is the only option, I could try to get it to one. Does anybody have any suggestions? Does this seem like a hardware problem that would need to be repaired?
Thank you,
Jack

Hi Jack,
It sounds like you have done a good job of troubleshooting. At this point we know you have a hardware issue. Fortunately you are still under the MacBook's hardware warranty, so Apple should repair it without cost to you.
Apple's retail stores are not the only source for service. Two other options available to you are 1) [Apple authorized service providers|http://solutionprofessionals.apple.com/aasp> and 2) call Apple (800-275-2273 in the USA) and set up mail in service.

PC cannot recognize iMac's external Hard Drive on network

I have a network with my PC and iMac. The iMac has an external hard drive that I recently added. I can see my PC from the Mac and I can see the iMac from the PC. What I cannot see is the external Hard Drive connected to the Mac from my PC, only the normal folders on my Mac. Can't find anything to allow me to do this.
Any ideas?
iMac Mac OS X (10.4.3)

Before I tried the software suggested I spoke with my son who finally gave me a script to enter in terminal which added the external drive as something that would be recognized. After a few tries it actually worked and I can read and write to my external drive from my PC. Thanks for the advice and assistance.
Now I just have to figure out how to get iLife 06 to load as it keeps crashing my Mac. Tried 6 times and now I have no iPhoto nor the iWeb, 2 of the 3 programs I really need and use!
Happy "Mac"ing.

Cannot mount any firewire/USB external drive after software update 10.5.4

After the last software update on 10.5.4 it did not complete the installation, and get stuck at the last step of running installation script for hours. So I have to restart the computer, and it restarted fine. Then I use Disk Utility to check my hard disk, and discovered some file system inconsistency error, so I repaired it (in target disk mode by another Mac). After it is repaired, the file system passed with no error.
But ever since then, I cannot mount any external firewire drive or USB drive. I cannot use Time Machine to backup my disk. I think my firewire and USB ports are fine because I can restart my iMac in target mode and connect to my MacBook via firewire, so the hardwire ports are functional, except that it seems 10.5.4 cannot detect or mount any external drive after the failed software update.
Does anyone encounter similar problem? How can I fix it? I have my disk backed up by TimeMachine but I cannot restore it if it won't let me mount my TimeMachine disk. Is there any other way other than completely reinstall 10.5 from scratch?

first, you should try reinstalling 10.5.4. download the [combo update|http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx1054com boupdate.html] and run it. If that doesn't fix the issue, you can use full system restore from TM to go back to a time before the troubles started. to do that boot from the leopard install dvd, once past the language screen go to the Utilities menu at the top and choose "restore from backup".

My imac is not recognizing any external dvd writer drive. I have imac with Core i7 and Mac OS 10.6.8. I have tried external dvd writers from Samsung and Amazon Essentials but the computer does not recognize any of them. Which Dvd writer is compatible?

I have an external firewire burner; it never shows on the desktop unless I insert a CD or DVD - that icon will then show (if I have my preferences set to show those on the desktop). Hae you checked in Disk Utility (Applications > Utilities) to see if it is listed under drives?

2.5" external enclosure (bus powered) any thoughts, experience, suggestions

I'm about to purchase a bigger hard drive for my macbook, I thought I could put the old one in an external enclosure that's bus powered, any experience with that ? I'm thinking about the Bytecc BT-280SATA but couldn't find it here in Quebec, Canada. Also saw the OWC Mercury on the go, but I find the pricetag a tad high at 90 bucks for an enclosure, couldn't find another SATA notebook drive enclosure that's bus powered though, I'd like to hear suggestion.
Would also appreciate a suggestion of where to purchase one of these enclosures in Canada.
Thanks, Francis.

You are rightm the price is a little high, but there are not a ton of choices when it comes to a SATA/FW enclosure.
TransINTL.com has one, but it is even more at $99.

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

My USB ports will not recognize any devices, iPhone or external drives. Keyboard and printer work, any suggestions?

I'd start by looking in system profiler.
the blue Apple icon > About this Mac > More info...
goto the hardware section. Scroll down and click on USB
See what happens when you have the device plugged in & not plugged in.
Move keyboard & mouse around to verify that ports work. Plug device in a port that worked with keyboar or mouse. Keyboard usb ports are rather low power.
Perhaps device is taking too much power. Are devices power or unpowered? Try connecting devices to a usb hub.

HT2499 I cant get my external Apple USB SuperDrive to recognize any of my dvds?

I cant get my external Apple USB SuperDrive to recognize any of my dvds. It only recognizes installation cds. Is there something I can do or is the device faulty?

Here are some troubleshooting ideas. The DVD read portion of the Superdrive may have failed. The CD uses a different reader based on what I was told by an Apple Store Genius when mine failed.

If you live near an Apple Store, make a Genius Bar appointment to have the computer and Superdrive tested. Supposedly there is no charge for testing.

Advice needed: Cannot boot from new external SATA drive/enclosure.

I replaced my two internal drives with 1Tb Seagate ST31000340AS drives.
I also bought a Mercury Elite Pro external enclosure from Other World Computing (OWCMEFW924AL2K) and populated that with two more of the same drives.
I have RAID disabled and am using Super Duper! to backup/clone my two internal drives to the two external drives. The drives are all working fine, as are all the possible connections (USB2, FW400 and FW800).
After a backup/clone, the Disk Info in Disk Utility shows the external system drive clone to be bootable (which it should be, as my previous external drives were). However, any attempt to boot from the drive via the launch-option key method or by changing the startup disk in the preference panes fails. With the latter I get a brief blinking folder question mark, then it reverts to booting from the internal system drive. With the former, I am not even shown the external drive as a boot volume.
So, what could possible going on here? All the hardware and cables check out, and in all the time I've used Super Duper! it has always created bootable backup drives.
I have tried both FW400 and FW800 connections for the boot, and nada.
I'm really at a loss to explain what might be going on.

After a lengthy live support session last night, and a further phone call to their tech support today, we both realized we had run out of ALL options to fix the problem. (There is nothing you could imagine that we didn't try).
In the end, OWC were kind enough to offer an overnight crosship of a replacement enclosure. I guess their suspicion is that there is a defect on the board in the enclosure. We'll see once I get the replacement...

In most locations your Apple ID is a valid email address. Did you try entering you most used email address?

IMovie cannot find vidoes in iPhoto since iOS6 update. It doesn't recognize any videos and all were taken with iPad camera.

I recently updated my iPad to iOS 6. It also updated many of my apps including iMovie. After the update when I opened iMovie, I got an error message saying videos in the project couldn't be located. It then asks if I would like to search for them, which I click yes and then I just get a message that an error occurred. I have even tried to add new videos to this project or a new project and it won't recognize any videos on my iPad, or pictures for that matter. It does find music. All the pictures and videos on my iPad were taken with the iPad camera, no other camera or app.

Maverick wont recognize my toshiba external hard drive. Any idea?

Maverick wont recognize my toshiba external hard drive. Two days ago, before attaining Maverick (what a mistaaake), it recognized the external. Now it only recognizes other external hard drives, but not my toshiba. All my music is locked away
Thanks for your time...

Once I press mount it says:
The disk "TOSHIBA EXT" could not be mounted.
Try running First Aid on the disk and then retry mounting.
I have a very valuble music collection on this. I got it around a week ago and it hasn't been acting the same since Maverick. I'm just hoping the problem IS maverick here. But it must be.... Because Maverick won't even recognize my brookstone mini projector. I really appreciate the help, what should I do from here?
