Envio 3TB Ext HDD not recognised

Hi My External HD can no longer be recgnised by my Windows 7 64Bit computer. It as always been a bit temperamental because I couldnt start up my computer with it connected. But now it says it cant recognise it and comes up with an error 43. I have tried to reinstall drivers but it still wont work.
I have a lot of irreplaceable info on the external HD and am really upset i cant get it to work
Can someone help me please.

The error 43 could appear due to different reasons and therefore its not easy to say what cause this HDD malfunction.
The issue could be caused due to faulty driver installation, faulty USB cable or USB port.
Its also possible that the system has been muddled up and the registry needs to be cleaned or repaired.
From my point of few you should check some essential workarounds.
First of all I would recommend you to connect this HDD to another computer.
Test it using 2nd notebook or desktop PC and connect this HDD to different USB ports.
Your computers USB ports should be checked as well. Disconnect all USB devices.
Go to device manager and delete all USB hubs, controller and ports.
Then reboot the system.
After new reboot, the system should initialize the removed ports automatically.
Last but not least Microsoft has published an troubleshooting document in order to fix the error 43 issue.
Error: USB Device not recognized when you try to access a USB external hard drive.

Check it too.
If nothing would help, probbaly the HDD is faulty :(

1.5TB external HDD not recognised on various laptops

Hi,
I was wondering if anyone could help me.
I bought my toshiba 1.5 terrabyte external harddrive just over a year ago. It works fine on my other laptop and my boyfriend's laptop but when I connected it to four other new laptops (all different brands) recently it was not recognised on these laptops at all.
Is there something wrong with my external or is something on these computers blocking it from being recognised? Do you know how I can fix this problem?
Many Thanks!

Hello
And if you connect the external HDD to your and boyfriends notebook everything is still ok? You have only problems with new notebooks?
Well thats really strange Have you tested another USB cable and different USB ports?
Maybe on the new notebooks the antivirus or firewall program is blocking the access to external drive. Check your security software and allow external devices.

Ms-6741 + SATA HDDs not recognised by xp setup

Hi all, i have been ripping my hair out for 24 hours about this machine.
It is a TINY PC with a MS-6741 mainboard. It previously had 2 SATA HDDs installed, both 200GB. 1 had XP installed on it and the other just data. The OS disk failed, many many bad sectors and errors. I bought a new SATA HDD (WD2500AAJS) and thought i would be able to install xp from either the tiny restore disk, or a standard windows xp disk. But I can't!
First problem (although not the worst) is that the BIOS does not recognise the 250 GB new disk, not one bit. Checked the sata cable, checked the power, checked the disk in another machine; all fine. So after some swearing I decided to copy the data off the data disk and use a disk the BIOS was recognising.
The mobo recognises it fine, but when i get to the xp setup to select disks and partitions it says 'no disk available'.
I did some reading and many people suggest that the XP setup disk doesn't have drivers to make SATA work, they suggest downloading the raid/sata driver from the mobo manufacturer website and pressing F6 at the start of setup, copying the drivers to a floppy and letting xp setup find the drivers and use them. I tried that, i tried both the drivers listed for raid on the MSI support page for this mobo, i tried getting the drivers for the VIA VT8237 SATA controller, they didn't work.
I have tried upgrading the bios, flashing it from a win 98 boot disk, following the instructions on this page http://www.msicomputer.com/support/BIOS_NON_FAT.asp This as far as i can see didn't work, it launched the flash utility fine, said 'deleting' and then 'programming' and said both had completed successfully. I restarted, went into the bios and the bios version hadn't changed. The only difference when i turned it on was that it said 'CMOS settings wrong'.
I am at my wits end, i have no idea what else to try. I read somewhere that TINY used to make their own version of BIOS which only allowed certain HDDs, maybe they stop you flashing the bios, certainly there is no setting in the existing bios saying, 'protect bios' or 'don't allow bios flashing'.
I would greatly appreciate any help.
Many Thanks
James

There you have all drivers for your board.
You probably have to make a driver floppy and load it during install with F6

Why are LR3.3 and ext hdd not communicating?

I store all my images on an ext hdd which is synched with LR on my MacBook Pro. A couple of days ago, everything was fine. Just started up ext hdd and opened LR, to be told to 'Click the import button to begin'. Everything in LR is a blank; no recognition at all of the ext hdd, so no images, no nuttin'. Any ideas about what's happened and how to reconnect LR and the ext hdd?

Thanks for advice. Also suggested on forum reply. It's done the trick and LR and ext hdd are talking again.

New HDD Not Recognised

I recently posted the following information:
I recently updated my iPhone (5) to iOS 8, and decided I might as well update my Macbook Pro to OS X Yosemite. After updating my MacBook for the first time, it started up just fine, but appeared a tad slower than usual. I figured it was due to a lack of applications I usually have running to monitor activity and help free up memory. After reinstalling all the applications I usually have installed on my laptop, it still feeled a tad slower, but nothing to be worried about. After a number of reboots over the course of three days, it suddenly refused to start up properly, showing me an error icon at startup, and shutting down later on.
After having googled around a bit, I read about the possibility of seeing what's wrong by enabling Verbose Mode. After having started up the laptop using Verbose Mode, I was shown the following error: "Error loading kernel cache (0x6)". After googling the error, I read that reinstalling the operating system was the only way to fix the problem. Seeing as I was unable to start up my laptop, I booted it up into recovery mode. As I bought the laptop with Lion preinstalled, it reverted the laptop to Lion, after which the laptop became unbareably slow. I then installed OS X Yosemite through the App Store, which unfortunately fixed neither of my issues.
Whenever I start up my laptop now, I am first presented with the error icon, which disappears after a while starting up normally. Then, when it is finally started up, I am once again presented with an operating that is terribly slow, and keeps freezing. Safari keeps freezing while loading simple web pages, regular applications take terribly long to start up, and every couple of minutes I am presented with "the spinning wheel of death".
After installing an application giving me more insight, I found out that the HDD was the cause of my problems. Thanks to "SMART Utility" I now know the error was an Interface CRC error. After googling for solutions, I ordered a new hard drive (750GB SATA III, Western Digital, 5400 RPM). When I received the hard drive, I installed it in my laptop, and booted into recovery mode. When I then went into Disk Utility (to prepare the drive), I was shown that the laptop didn't recognise the drive. Figuring that it was a malfunctioning hard drive, I ordered a new one from the company I ordered it from, and returned the first one. Friday my new drive arrived, which is giving the same problem; the hard drive is not being recognised by the laptop.
Considering the old hard drive does work (just not properly), I figured it's not the cable causing the new hard drive not to show up. Am I just having real bad luck (in other words, did I receive two broken hard drives), is there some step I'm missing while trying to set up my new hard drive, or is there something else wrong with my laptop?

The only time I recall this happening to me was when I didn't have the SATA connector totally seated into the drive.
When you boot into Internet Recovery (command+option+R) have you launched Terminal and tried the diskutil list command to see what comes back? If you see that your new drive is coming up as disk0 or disk1 or whatever, you could try the diskutil eraseDisk JHFS+ "Macintosh HD" /dev/diskX command where X is 0-9.

External HDD not recognised in Mac Book Pro

I am trying to connect a external HDD to the MacBook Pro. The external HDD used is Seagate FreeAgent GoFlex 1 TB powered by a USB cord connected to the laptop. The light on the HDD is not glowing neither does it feel like moving when touched.
Can somebody come back with a solution to get the HDD working on the Mac?

By placing the HDD in a different enclosure, one would be testing if the enclosure circuitry is faulty. Since it works on a PC, then that is not the problem.
noondaywitch may be on the right track. I note that your HDD has an optional Firewire connector available. You might order that or get a 'Y' connector where there are two USB connectors that you would insert in two USB ports on your MBP thus gaining more power for the Seagate. No guarantees of success with either option.
Ciao.

ESATA HDD not recognised on cold boot, OK on reboot

Hi, I have a HP Elitebook 8740w from which I have removed the internal HDD and connected an eSATA HDD which is powered from the USB bus (I've done this for security purposes). I'm having a problem whereby when booting at initial power-on, a Non-System disk or disk error is encountered after the HP screen. I can then boot into Windows by pressing CTRL+ALT+DEL however having to do this each time I start up is not ideal. Also this error is not seen when rebooting, only at power on. I have tried powering the HDD from the supplied AC power pack and the problem disappears which make me think it is an issue with the USB power (either insufficient current supplied or full power is not available at start up). I have tried all combinations of USB2.0 and SuperSpeed USB ports with the supplied USB Y cable without success in removing this error. Any ideas? I would prefer to run the HDD from the USB ports to save carrying the AC power pack and because often only one power point is available. Thanks

I think I've worked it out... I was running the laptop on mains power only with battery removed. Tried it with the battery installed and problem disappears, it must provide extra power at startup to spin up the HD. Laptop AC adaptor is 200W though, would have thought this would be enough...

USB External HDD not recognised in OSX 10.5.4

Hi,
I am attempting to use an ISOGEAR250 2.5" IDE external HDD on my iMac.
This deviceis advertised as 'compatible with OS/X', which is in fact only true up until version 10.4.9.
The device is not detected on any OS/X version with the IOUSBMassStorrageClass.kext or IOUSBfamily.kext kernel extensions of any version of OS/X past 10.4.9.
The only way to get this device to detect on Leopard is to revert the specific kernel extensions to earlier versions, and use the USB Prober utility. This is quite a dangerous exercise, and can lead to operating system instability.
I have tried the device on numerous Apple computers, and it only works on the ones with OS/X 10.4.9 or earlier installed. I have also experimented with many different file system formats. This device works fine on Windows machines, including Windows in Bootcamp, and Windows using VMWare or Parallels.
For your information, the device does turn up in the System Profiler with the following info, but will refuse to mount with kernel extensions past version 10.4.9:
USB4500 FW1.04:
Version: 0.001
Bus Power (mA): 500
Speed: Up to 480 Mb/sec
Manufacturer: DATAST0R Technology Corp
Product ID: 0x4500
Serial Number: 1966XXXXXXXXXXXX (I added in the X's)
Vendor ID: 0xed06
If I plug the HDD in while my iMac is sleeping, it will wake up the iMac.
I have tried the device on both the iMac's built-in USB ports, as well as with a powered USB hub.
Numerous other users have had similar of the same problem
(see: http://discussions.apple.com/thread.jspa?messageID=7835455), and yet Apple has not yet rectified the problem, which is clearly arising from the update to the operating system, and not the device itself.
Does anyone have a fix for this problem, aside from reverting the kernel extensions and using the USB prober?
Thanks for your help,
Cal

From searching the web, I am tempted to say the Iso Gear is quite an exotic device.
It's up to Astone them to deliver a firmware upgrade for their device to work with Mac OS X 10.5, as Apple probably follows USB 2.0 standards when accepting (or not) an external hard drive.
diskutil became more picky in 10.5 (been bitten myself) but still, I am not sure whether this is due to Apples development teams faults or due to to Astone following standards.
There has been an issue in 2006 with LaCie drives on OS X 10.4 which were resolved by their firmware upgrade.
I know this is of no help to you, but consider not just talking on Apple forums about this but also on Astone help channels.

External USB-hdd not recognised by Finder if connected to Time Capsule

Hello!
I'd like to connect a small external harddrive (40 GB) to my Time Capsule (1 TB) via USB.
I've read on http://www.apple.com/timecapsule/wireless.html the followings:
"... +And if you want to share both a printer and an additional hard drive, you can. Just connect a USB hub to Time Capsule.+ ..."
While I've connected two printers to Time Capsule - so I already use a USB hub - I've tried with the external USB-harddrive, but it wasn't recognised neither by the Finder, nor by the DiskUtility-app. The external USB-harddrive appears not even if I connect it directly to the Time Capsule!
Restarting the Time Capsule / USB-hub / external USB-harddrive / my Mac doesn't change anything
The external USB-harddrive appears only in the AirPort-utility app (5.4.2) in "manual Config" - "Devices", but even here only as a possible archiving device for the internal Time Capsule harddrive.
The USB-harddrive itself is formated as Mac OS extended (journaled) and it works like it should on my iMac (3.06 GHz, Mac OS X 10.5.7).
Do you have any idea why the external USB-harddrive doesn't appear when connected to the Time Capsule?
Thanks!
Regards,
Vlad

Vlad, this might help...
*Accessing External Hard Disk*
Open a Finder window
Select the Time Capsule in the Sidebar on the left.
Click "Connect As..." in the upper right of the window.
Enter the Name of your Time Capsule & its' password (Note: NOT your own Username & password).
Check "Remember password in my Keychain."
You should now see a blue share folder with the name of your Time Capsule.
Any hard disks attached to the Time Capsule’s USB port will also appear here as blue share folders. To mount them on your desktop double-clicking their blue folders. If you had a separate password setup for those disks in Airport Utility then enter that password if asked. Otherwise, it should now mount on your desktop.
Let us know if this solves your issue. If, however, the drive is not showing up either on the Desktop or the Sidebar, you may still need to do the following...
*On Desktop*
In the Finder, go to the Finder menu and select "Preferences".
Click “General” in the toolbar.
Ensure that all the items under "Show these items on the desktop" are checked.
Close the preference window.
*In Finder SideBar*
In the Finder, go to the Finder menu and select "Preferences".
Click “SideBar” in the toolbar.
Ensure that all the items under "Devices" & “Shared” are checked.
Close the preference window.
Did this resolve the issue?
As for Disk Utility, bear in mind that DU won't "see" network attached storage devices unless they are already mounted on the Desktop. And even then they are sometimes not "seen" by DU. If you are going to do any work on a network attached storage device avoid attempting to do it wirelessly. Best to connect it directly to the Mac (USB/Firewire), or at the very least via ethernet.
Hope this helps. Cheers!

Upgraded to msata but now original 320 Gb HDD not recognised

Hi all
I just upgraded to a msata which works absolutely fine. However the HDD refuses to be recognised in BIOS or in windows 7, I just get a 2100 error on booting. I can boot into windows after pressing a few keys but the hdd is nowhere to be seen in windows. Is there any way to refresh the hard drive list or do a low level format?
Lenovo X220 | i7 2620M @ 2.7Ghz | 8GB Crucial Ram | 120GB RunCore msata SSD | 320 GB HDD | Windows 7 Professional 64 | BIOS 1.21
Solved!
Go to Solution.

No it's more complicated than that.
I replaced the original HDD with a Crucial C300 256 GB SSD but that died when I put the laptop down on a worktop one day. At the time I thought it was the loose battery that had turned off the laptop.
I am doing a RMA on the SSD to get thta replaced. In the meantime I thought I would put the old drive back in and add a msata to get better storage space but the old drive refuses to be recognises by the laptop. The msata works perfectly and is only slightly slower than the C300.

Extermal Toshiba USB 320 GB HDD not recognised correctly

My hard drive does not now recognize itself as a hard drive anymore just a Cypress AT2P RC42 and so is now useless after a couple of months use.
I have uninstalled and reinstalled through device manager. I then tried it on another computer and I have the same problem, therefore it is the hard drive and not the computer.
It is an external USB toshiba 320GB drive which previously worked fine but now thinks its something else and nothing else.
What can I do to rectify this problem? Please help all my data is on this drive.......

Ext HDD seen by 2011 MBP but not 2014 MBA

Hi all
My GF just unboxed a new 13" MBA. One of the models refreshed last week
She wants to set up fresh & just bring over some data from ext HDD's she used with her old MBP.
It is a 2Tb Seagate Drive (USB 3), which has an external power supply.
The drive is formatted into 2 partitions, a 1.5TB OSX Journaled and a 500Gb FAT-32 (for when she needs to transfer files to/from a PC).
The drive shows up fine on her MBP just fine. In Finder & Disk Utility.
However on the new MBA, there is no signs of it at all. Disk Utility & Finder shows nothing.
Both left & right USB ports on the new MBA work ok. I can see a different Western Digital (USB 2) powered ext. HDD no problems.
The Seagate drive LED lights up when plugged into the MBA and you can hear it spinning, it just won't show anywhere in the OS.
Any ideas brains trust?
I've done all the usual troubleshooting.
Could it be something to do with the firmware on the MBA needing upgrading?
Thanks, Luke

hi
typo mistake, what I meant to say is that your external HD is recognised by you old MBP and it is running in MBA but not shown (not being recognised as external USB) as you said that "The Seagate drive LED lights up when plugged into the MBA and you can hear it spinning, it just won't show anywhere in the OS." , have you checked that the power for the exHD on? because as I said ealier that I have ex HD imation 1 Tb used as backup for TimeMachine and someday forgot to turn on the power supply but when the exHD was plugged, the LED ON and I could hear the drive running, unfortunately not recognised by me MBP until I turned the power on. If the power is ON in your exHD then I suggest to contact apple customer service not the community only as you MBA is 2014 and under warranty

Toshiba Ext.HDD 320GB USB wire not working?

So I have a Toshiba External Hard Drive that connects plug and play via USB 2.0 wire Male A to Mini B. Problem is, is that I have about 5 usb 2.0 wires all ranging from 2feet - 6feet in length and absolutely none of them work. I used to have one that worked it seemed a bit thicker than other USB 2.0 wires but lost it and am using a friends 6 inch us 2.0 wire that works fine but seeing as it's his I need to acquire a new one. I don't want to waste money on a wire that won't work so I was wondering if anyone at all knew what the problem seems to be. I have searched the internet for the solution as well as went to the local tech shop and they had no clue what the heck was going on. The man there said it was probably the length of the wire but the original USB 2.0 wire I had was about 2.5 feet in length and it worked fine. It's not a problem with my ports seeing as my frineds works in all the ports and not a problem with vista obviously seeing as yes, it works. I just need my own USB 2.0 wire and need not to waste money on something that won't work. Anyone with a solution please? Thanks!
*the hard drive powers up with the wires I have but Vista won't recognise it*
*the drivers do not need to be installed seperately seeing as it is plug and play and has all drivers on the hard drive itself.*

Check all usb cables to learn if signs of wire crimping/bulge is observed, those need to be replaced. Length not too much of a problem these days. Generally, belkin have good cable units. If there is too many plugged into the laptop could cause non-working conditions and recommend a usb hub to be utilized, worth a check out. You could also deinstall the USB controllers via Device Manager and reboot, let hardware wizard reinstall.
On the external HDD not recognized, put the disc that came with the device. When not recognized no driver is on board yet, but you will still get some sort of indicator of an attempt at install. Try putting usb into the laptop after it has been operational. Check Computer to see if it is recognized, and take off all other external usb units.

Excluding items from back up and Time Capsule not recognising ext HD

I'm relatively new to the world of Time Machine and Time Capsule. I have a 250Gb iMac, but because my iTunes library was becoming so large I purchased a Iomega 500Gb ext HD and transferred it over to this where it is currently occupying about 350Gb of space. I still have about 220Gb duplicated on my iMac at the moment as a kind of back up. I then discovered Time Machine and because there was only about 100Gb of space left on the ext HD to do back ups on I excluded my music and iTunes library from this. This has been going along fine for the past month.
I purchase a 2 TB Time Capsule (TC) yesterday. I reconfigured Time Machine to use the TC as the back up and I removed the excluded music/iTunes library so that everything would be backed up. As soon as I asked TM to back up it started excluding millions of items which I am assuming is related to the ext HD since when I turned this off it started to back up my iMac computer content correctly. However I want to be able to back up the stuff I have on my external HD so that I can eventually delete all the duplicated stuff off the iMac. I read a similar post on here about this and have tried deleting all the old TM backups but it is still not recognising the ext HD. I currently have it connected via an ethernet cable just to speed up the initial back up. Any help or explanations would be greatly appreciated.

Dear Bob
Thanks for trying to help me with this

Sorry, I am confused here. You mention that you have a new 2 TB Time Capsule, yet talk about trying to delete old TM backups. What old TM backups, if you have a new 2 TB Capsule? Can you clarify, please?
but it is still not recognising the ext HD
A bit more clarification here, please. When you refer to "it", do you mean Time Machine?
Time Machine will not backup an external drive connected to a Mac unless the drive has been formatted in Mac OS Extended (Journaled). Did you format the drive this way when you first got it?
If the drive was formatted as FAT32 when it was new, it would work OK if you attached it directly to your Mac. But if you want Time Machine to backup the Iomega drive attached to your computer, the drive must be formatted correctly to work with Time Machine.
If you have the drive attached to the Mac and you open Time Machine Preferences and click Options, can you "see" the Iomega drive and not select it, or can you not "see" it at all?
If you can "see" it, but it is grayed out so you cannot select it, the drive is not formatted correctly as mentioned above. If that is the case, you will somehow need to copy all of the data on the drive to another location, format the Iomega drive to use Mac OS Extended (Journaled), and then transfer the data back to the Iomega drive. Then, Time Machine will backup both your Mac and the external drive attached to your Mac.
