Hard Drive not being recognised in BIOS - Equium A60

Hi hope someone can help. I have a Toshiba Equium EA60-173 and the hard drive is not being recognised in the BIOS. When I take the hard drive out and put it in another laptop it is detected fine. I have also tried another hard drive in the Toshiba and that doesnt work either. Therefore I suspect the IDE controller has gone, but is there anything I can do to confirm this? I wish there was some option in the BIOS to force a detect. I have successfully updated the BIOS but still the same.
This laptop is only just out of warranty so if it is the controller would I need to replace the motherboard? Are there any other options available to me?
Thanks in advance.

Hi Neil,
Unless there is some physical\problem with the Hdd connector/cable then it is quite likely that you will need a new mainboard for your notebook. I suggest you contact an authorised Servic Partner and ask them to check your notebook and give you an estimate of the costs of the repair. Then you can try to shop around for any cheaper alternatives.
regards,

LaCie d2 500GB Quadra Hard Drive Not Being Seen By Time Machine

Hello all,
I have a LaCie d2 500GB Quadra Hard Drive Not being seen by Time Machine hooked up to my iMac via firewire 800. My iMac is running latest updates etc. Have raised a support ticket and was given the following instructions by LaCie:
Posted: 08 November 2007 @ 00:00
Thank you for contacting LaCie Technical Support. Make sure the drive is mounting and you can assess files on it on your 10.5 system. If you can then you will need to reformat the drive to make it compatible with time machine.
Warning! All data on the external drive will be destroyed in this process.
Step 1: Run Applications > Utilities > Disk Utility
Step 2: Click on the LaCie hard drive's 'physical' entry, usually the third entry in the list
Step 3: Click on the Partition tab
Step 4: Change 'Current Scheme' to '1 Partition'
Step 5: Change the name of the drive back to what you would like it to be
Step 6: The format needs to be Mac OS Extended, with or without journaling
Step 7: Click on the Options... button
Use "Apple Partition Map" partition scheme on a PowerPC-based Mac.
Use "GUID" partition scheme on an Intel-based Mac.
Step 8: Click on OK
Step 9: Click on Apply
Step 10: click on Erase at the bottom of the screen, then confirm the erase.
The drive should start to be reformatted which should take only a few seconds and show up on the desktop with a new icon. Once it has you can then use it with time machine.
I have done all of the above and it is still not being seen. Anyone had a similar issue or got the above to actually work?
Thanks in advance!!!!

Ryan,
Check drive volume name and also the Computer name. Apple released a tech note recommending that both be limited to only the characters A-Za-z0-9 (no dashes, hyphens, or other special characters.
If you can, send the Apple System Profiler report to me at the addres in my profile. Imay be able to see something there. I have helped another user with similar problems, but with a LaCie USB drive. He got things working by repeating the recommended steps, and double checking everything.
As others have rported, this should work, so there may be something else preventing proper operation.
If the drive is usable from Finder, but Time Machine cannot use it, there is something related in how Time Machine is viewing the drive.

Hard drives not being recognized on Server 2012 R2

Hi,
I added 2 hard drives to my server but they are not being recognized by the operating system. They show in the bios but no where in the OS do they show. They used to be external hard drives but I took the hard drive out and installed them into the server.
Are there some type of drivers I need to download for them to be recognized? One of them will be shown but it tells me I need to reformat it. I don't want to do this since I have about 1TB of data on it.
Thank you,
James

What server hardware is being used? May need the manufacturer chipset and support pack in the case of integrated disk controller.

All external hard drives not being seen after working for months

I have a 27" iMac, 10.7.2.
This morning I had 4 external hard drives attached via a powered hub, 2 x 2TB and 2 x1TB (all Freecom) formatted as MAC OS extended Journaled, one acting as the time machine backup.
All were working and being recognised/seen on the desktop and finder and working normally. I shut down the system and moved the machine to a new office made all the same connections, but now none of the drives are available, they are not even visible on the desktop.
I have tried them directly connected to the usb ports with no luck, I have tried rebooting in safe mode and reset both SMC and PRAM (after looking at various threads)
I have also tried a USB stick which also does not appear on the desktop (or anywhere else), all other peripherals work with the USB ports.
This is a real problem as there is almost 4 terabytes of material and four years work!, any suggestions would be greatfully received.

You mentioned you did a SMC reset, because different models of Mac's have different procedures for doing a SMC reset you may have done it incorrectly meaning you didn't do one at all! Did you do it like this?
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.

Hard Drive not being recognized on my Graphite Clamshell

I have a challenge for anyone. I have a ibook 366(clamshell) that is not recognizing the hd. It was working wonderfully one night I shut it down and the next day I get the flashing question mark. I've tried all of the normal stuff: zap pram, reset nvram tried to use command and s but it didn't go to the programmers screen and all the such. I can boot from a cd but none of the utilities see the hd. I have taken the hd out and connected it to a usb to ide cable that allows me to use it as an external drive and it is recognized without any problem on all of the other macs I connect it to and even on a pc (I know I said the bad word.)Does anyone have any clue what could be the issue. Every thing else seems to work fine. Just the hd is not being recognized. I even put in a different hd. I even formatted the drive using one of my macs that I only have 9.2.2 on and installed a os on it and it still didn't work. The hard drive worked fine and the os with all of its components seemed to be fine. I know it's an older system but it's something that I can let the kids play on and not be concerned with losing any of my files.
I appreciate any help
iBook 366 Graphite

Duane, Thanks for your reply. Is there any way to test this? I am going to try to see if any of the utility disks can recognize the hd. I've tried DW 4.0, the Utility Disks on OS 9, X. I've even tried FWB and a few other tools.

Mac air with external hard drive - not being found on Finder, Time Machine, Migration Assistant

I have been using an external drive (Imation Apollo) to access only, old files from previous computer (PC) on a new Mac Air. I had not transferred them across to new computer (didn't want to do that) just accessing them from the HD. It had been working fine until recently. Each time the external drive had been connected Time Machine would come up and ask if i wanted to use this drive for back ups, and I always chose 'Decide later'. So, as yetI hadn't as yet configured Time Machine to do back ups.
Recently I noticed that the extrnal HD was no longer showing up on Finder. Slight panic as i have 5 or 6 yrs of work saved on that HD
Further investigations - it's also not showing up either on on Disk Utility, or on Migration Assistant.
I've done the following:
Tried HD in each of different USB ports - made no difference, HD still not showing up
Tested different Hubs in each port with HD attached - no difference HD not showing up
Tried USB flash drives in the USB ports - These are working fine and show up on finder
Tried the HD on other comptuters (a PC though, don't have access to another mac to do this test)- working fine, the HD is showing up and is accessable
Interrogated the Console logs to try to see if the act of attaching the HD creates a log entry - couldn't find anything
Rebooted computer via shut down, power disconnect - no difference
Reset PRAM - no difference still not showing up
Reset SMC - no differnce still not showing up
So I think I have established that all the USB ports are functioning correctly and able to access other external drive devices, using hubs with external powersource is not the issue, identified that the external hard drive is working OK, and it appears that the Mac itself is functioning normally.
What would be the reason the Mac now does not allow this specific external HD to be identified and accessed. The only possible things I can think of are
if I had in fact pressed 'Do not use' when Time Machine asked 'do you want to use this drive for back ups'. Would that mean that the Mac now totally rejects this HD from being a source of accessible files - I hope not!
I also think that my husband may have disconnected the hard drive from my computer to access some stuff and he just yanked it out rather than use the safe eject method. Could this create an issue? The Hard drive works fine on his PC.
Why is my Mac Air now rejecting this HD and what can I do to access my historical files now.
Any assistance anyone can provide would be very greatly appreciated!
Thanks
Anna

I can't answer why it isn't accessing it, but I have a slightly related issue w my back up drive starting to get noisy.
Realizing that redundancy is safety for critical data. I talked to my brother about my situation the other day & he said he has 3 small Western Digital portable HDs that he rotates for backup. He even keeps 1 in the safe deposit box.
I have read for some time that we should have multiple back ups & also have our critical stuff backed up off site. Amazon HD reviews had a woman telling about how she was very backed up on multiple computers & hard drives, but they were robbed or burgeled & all of them were stolen including her thesis that was on the computers.
Hard drives aren't that expensive. I just bought a new Western Digital 1 TB drive for $89.99. I plan to use it to back up the Seagate that is getting noisy & then maybe alternate them.
Also, when I came back to Mac, I moved practially all of my documents to Mac. I think I just dragged & dropped or something. Photos, Office, & pdfs do fine that way. & then you could back them up to a couple of different external drives & remove from your MacBookAir.
Unfortunately I think most of us do not back up until crisis & then it may be too late.
Also use Time Machine. For the 1st time in my computer life, my computer is well backed up--although now realizing the need for redundancy so will start backing up to at least 2 different HDs alternatly.
So, not sure why it isn't working & hopefully you have come up w a solution by now.
I think what I would do in a situation like this, since you can access it on the Windows machine would be to transfer the data to the Windows machine & then transfer it back to a different back up.
I'm looking into backing up what I still have in Windows using a thumb flash drive. I think it should all fit ok now that they have the larger drives & I don't have very much left in Windows format.

External hard drives not being recognized by Lr4

When I hooked up my two external hard drives to my computer this week, Lr4 is not recognizing them. Each folder has a question mark by it.
Appreciate any help..thanks!

Hi Jim,
I spent some time doing maintenance on Lil's computer. We were on public networks for 10 days and so I ran some cleanup software to help ensure that we don't have some virus or other malware messing things up.
Then I did some comparing and it appears that Lightroom has the G and H drives reversed.
I have enclosed 4 screen shots. Two show the strong(but not perfect) correlation between LR drive G and Explorer drive H........and vice versa. Another shows the K drive and the fourth shows the G drive one level up as you requested. I believe that when we disconnected this computer to take on vacation that we just pulled all the plugs and did NOT take any steps to "logically" disconnect them. If LR is sensitive to drives just being removed by pulling the cable, then perhaps that contributed to this situation...although I believe that we used the same procedure in the past.
Thanks,
David Polley

External Hard Drives not being recognized

I have 3 external hard drives. Had them for a long time now. I recently made only one change: I decided to start using the 'sleep' mode.
I noticed the sleep mode and external hard drives didn't get along real well, so I simply took the externals (used only for backing up data) and turned them off.
Its now been about 2 weeks, time to fire them back up and backup my data. Only one of the 3 is being recognized. The other two seem to come on, make the usual whiny noise and such, but aren't seen in the finder.
I've tried restarting my computer, turning off/on the hard drives, unplugging/replugging them from power, unplugging/replugging them into USB. I've verified connections, that kind of thing. Nada.
Any ideas on what to do to help my computer 'see' that they are there? this is a bit baffling to me and disconcerting, to say the least. I've never had problems with my computer recognizing the externals before.
Ideas are appreciated.
PowerMac G4 1.42 duel Mac OS X (10.4.6)

'sleep mode' ?
Do you mean the drives are triggered to not spin up for a period after powering on ? This is a feature designed for enormous banks of drives, so that when they are powered on, only a fraction spin up immediately, then another set, usually 12 seconds later, then another set, etc, until all are up to speed. This is reduce the power surge from spinning up 700 hard drives simultaneously in a commercial solution.

Upgraded hard drive not being recognized

I've upgraded the hard drive in my new Unibody 15" macbook pro to a 7200 rpm Hitatchi Travelstar 7k320 from the original 5400 rpm drive. When I boot from the installer CD, one of the following occurs:
•I am able to open disk utility, see the drive, and reformat/re-partition it. However, the installer fails to copy files to the drive and stops after about 1%.
•Disk Utility fails to erase/re-partition the drive, and the installer unmounts the disk
•Disk Utility does not list the drive as an option at all.
Does anyone have a possible solution? Applecare wouldn't help me out being that the drive is third-party.

Prep the new drive as follows:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Hard Drive not being detected

So my work was giving away old Power Mac G5. They were old and were restored to factory defaults. I wanted to mainly use it for storage. I went out to the store and bought a 1TB hard drive. When I installed it, I got a message saying that the OS couldn't read the hard drive. I figured it was because it wasn't in the correct file format. I went to my disk utility to try format in the Mac OS Extended format. After the two hour format process, I restarted the computer from some other software I was installing. Upon restart, the new terabyte drive wasn't detected. Here is a copy of the Disk Utility log from when I first turned on the system with the hard drive being recognized till when I restarted the system.

As of right now, the system does not recognize the hard drive. I know the connection is good because I have another hard drive that reads just fine. I don't have another place to test the hard drive because I only have an iMac. Can anyone help with this or provide any pointers?? Currently running Mac OS X 10.5.8 Dual 2 GHz Power PC G5.

So I actually seemed to have solved this, to a degree. From what I could read through other help forums, there seems to be a limit on the transfer rate between the system and the hard drive. The OS has a cap of 150 megs/sec, but the hard drive operates faster than that. In order to fix this, you have to put a jumper on pins 5 and 6 on the back of the drive. This was slightly annoying because the hard drive does not come with jumper connectors. I had to find a jumper from another hard drive, and even then, it didn't fit exactly and had to use some strength to get it on.
While it does seem to be operating without any issue now, I still don't understand why it was able to read and detect the hard drive prior to formating.

External Hard Drive Not Being Recognized By MacBook

My Toshiba external hard drive (1TB, brand new) does not show up anywhere on my MacBook Pro (Also brand new). The light on the external hard drive comes on so it's not a connection issue, like the cord being broken. But nothing happens when I plug it into my MacBook, aside from the light coming on. It doesn't pop up on the desktop or in disk utilities or finder. I don't have my old PC laptop any more, all my files from that computer are on this hard drive and all I want to do is transfer them to my MacBook. And even though I don't want to lose any of my files, I can't even erase anything on the external hard drive to reformat it because it's like...not talking to the MacBook...

Your Mac should be able to recognize many different types of drives (including Windows-formatted drives) immediately for Reading, provided they are in good working condition and not damaged. There should be no need to transfer to a different type of drive.
If there is no recognition of this drive, see if it can be seen in Disk Utility.
If your aim is to transfer the data on it DO NOT use ERASE or PARTITION as these will completely erase all the information on the Drive.
If the drive is present while the Mac sleeps, it is likely to drop out and not be seen any longer, especially if it is a USB-powered drive.

Hard drives not showing up in BIOS of UCS C22M3 Server

Hi there,
I am wondering if someone can help me work out why my internal hard drives aren't showing up in the BIOS. When I enable the RAID controller and set up an array they are detected and placed online, but if I remove the RAID array they do not show up in the BIOS as a device from which I can boot from. I am using the onboard SCU as the RAID controller and it makes no difference with this enabled or not, the internal hard drives do not show up in the BIOS. I have tried many different combinations but are unable to ever see the drives listed in the BIOS. Initially when I first received the server I was sure this was the case but have since formatted the drives. I have also tried resetting the BIOS settings to default.
I would be most grateful if someone could help me as I have been working on this problem for a long time with no success.
Thanks in advance.
Tim
This image shows the drives with the array active, if I remove the array the drives still show up on this screen but not in BIOS.

Hey Tim, welcome to the communy!
I don't think you are even supposed to see the individual disks as a boot option. For all I know UCS is not intendeed to use its disks as JBOD (we'll see if that changes with new technologies like Hadoop) reason why you dont see the disks; you can see the RAID controller as a boot option if you enable it to control the disks.
I made the test in a C220 with a PCIe RAID controller (I don't have a C22 but it is very similar) and when I went to BIOS I didn't see the disks listed either, then I rebooted and pressed F6 and still the disks are not showing up, only the PCIe RAID controller showed up as a boot option:
Last 2 things:
1-Why do you want to see the individual disks as a boot option?
2-Have you check another C22 or any other model to see if the behavior is different? If this does not happen on other servers (which I think it is NOT going to be the case) open a TAC case for further investigation.

Problems with Starcam clip driver not being recognised / working.

Hi
I have recently purchased a starcam clip as my wife kept nicking my web cam to skype her sister.
I installed as per the instructions and it did not work so I de-installed and then went to the MSI web and got the latest driver for XP. This then works ok until i either unplugged the camera or shut down. I then have to re-install each time i want to use the camera >:(. If i have the camera plugged into the same usb as the last install then the computer (Acer travelmate ) shows the camera installed and plugged in but wont actually work unless I re-install . any suggestions?

Hi I have now made some progress. If I run the setup.exe as downloaded from the MSI web site the camera works as I would expect. (colour washout aside - but the thread on the 370i cam has explained this)
(1)The next time I start my computer the camera is recognised but Amcap has the error message of "This graph cannot preview" . The camera is listed in my computer but if I select the camera I get "creation of video preview failed - Check connection and check it is not being used by another application".
I can get the camera to work by running the setup.exe file again but this is a drag.
(2)If I swap to another USB port then I get the "found new hardware" icon and the new hardware wizard starts.
(3)If I start up with the camera unplugged and plug into the port on which the camera was in on the initial installation then I get the same result as (1).
Anyone any suggestions - I do not believe it is a hardware (camera) problem as it does work when initially installed.

External USB hard drive not being recognized

Hello! I'm sure this has been posted before, but excuse my naivety with this sort of thing...
I have a mac mini 10.5.6 (1.83 GHz Intel Core 2 Duo) and I run the Time Machine function to an external usb hard drive. The hard drive worked fine (plugged into the usb port on an older keyboard), but I went out and bought a new aluminum apple keyboard (because they look so cool ^_^ ) - I plugged the external usb drive into the keyboard and it wasn't recognized, so I tried plugging the external drive directly into the mac mini, but it is still not recognized. It is not showing up in Disk Utility or in System Profiler
Help? I'd hate to have to give up this fancy keyboard...
Thank you!
Dr. E

I believe I had my external drive plugged into the (old) keyboard because with the old mac that I had didn't have a free usb port for it - so when I got the mini I just plugged things back in where they were. But I have always had the Time Machine back up to this drive (connected to the keyboard) though it has been slow (another reason I thought the new keyboard was a good idea).
I tried restarting the computer without the alu keyboard plugged in, but same problem of no drive showing up.
Here is what System Profiler has to say about my drive:

I don't know the brand or model as it has 'always' been in the case that in which it currently resides and I didn't physically buy the thing :\ I do know that no software was installed with the drive as I assumed that when I put all the old info from the original mac to the mini that it was the sort of thing that would carry over.
Sorry I'm not terribly helpful - Thank you!

External Hard Drive not being recognized

I made a topic some time ago but it never got answered.
http://discussions.apple.com/thread.jspa?threadID=1906969&tstart=0&messageID=906 6822#9066822
This hard drive has never worked on this computer and I am still not sure why. It does not show up in Disk Utility or in the System Profiler. It is formatted in FAT32. It is plugged into the wall and comes right up in Windows. As a test I used bootcamp and went into Windows XP. Plugged it into the same USB slot on the side and it came up. But upon rebooting into OS X it was no longer recognized. I actually got it to come up one time by opening USB Probe. After unplugging it and plugging back in, it no longer worked. I don't know what I did that one time but it will not come back. The time I had it running I moved files around to make sure it was working and it seemed fine. Does anyone know what I could do to get it working?
Model: Acomodata Model HD250UHE5-72
Thank you very much.

OK. They're supposed to be Mac compatible.
I guess you could see if it at least is recognized by the operating system even if it doesn't mount. You can open System Profiler in Utilities (or About this Mac > More Info...). The USB device tree should be under Hardware > USB.
