2nd Internal Hard Disk Not visible on desktop

Hello,
Last night I was trying to rename some files and my G5 was acting very slowly. I relaunched the finder and it seemed to fix the problem. I resumed renaming files and it kept locking up. After the fourth time this happened, the system locked up and I pushed the front power button until the system shut down. When I turned the computer back on, my second internal hard drive was not visible. I looked in disk utility and did not see it, and it is also not visible in about this mac. Help!!!

HI
I have a similar problem that the second drive does not always appear on starting up from cold but usualy appears on a hot restart
second drive is a Hitachi HDS725050KLA360 primary drive: HDS725050KLA360 (465.76 GB)
(Telephone support was useless)
It has been operating since March Photoshop and Aperture applications I do power down every night.
And back up to external just in case I loose it but would prefer to have more confidence in its reliability
Has anyone else had similar experience ? and any idea what might be the cause?

WD 1TB ExternaL Hard Disk not seen on desktop/finder

I have been using WD 1TB external USB hard disk for 4 months with my Macbook with Tiger 10.4 on it. I have plugged in the disk after I purchased without any special formatting or anything, and it worked fine so far. It just took a while, about few minutes, for the Macbook to show it on the desktop every time I got it disconnected and connected again. However, this time, I can not see the disk on the desktop nor on the Finder no matter what. I have plugged it in and out several times, I have restarted the machine etc. Nothing works. The disk is quite empty and it works fine with the PC..no cable problem or and disk failure issue for sure. I can see the disk on the Disk Utility app, but I can neither verify nor mount it...Any suggestions would be very helpful..thanks in advance

Unfortuanately WD external HD's have a pretty bad reputation with Macs. It has something to do with their enclosures as their internal HD's seem to work just fine. I would recommend exchanging that drive for one with a higher quality enclose. Just about any other manufacturer would be fine however the 3 best IMHO are:
OWC Mercury Elite Pro series
Lacie Quadra d2 series
G-Tech G-Drive series
All have similar features and build quality. I would be comfortable using any of the three but I've been successfully been using the Lacie's for 3+ years.

Time Capsule internal hard drive not visible

I have one of the older 500GB TC. It worked fine for a year then I decided to wipe the hard drive to erase the contents. I stopped the process in the middle of clearing the hard drive because it was going on about 8 hours. Every since then the TC works fine as a wireless router, but the internal hard drive is not visible. It won't do any back ups and it's not visible in the Airport program.
Any suggestions?

Internal Hard Drives not showing on desktop (Yosemite)

External drives show up just fine. Computer is a 4,1 Mac Pro upgraded with a 5,1 6-core 34.6GHz processor. Main drive is a Corsair 512GB SSD and second drive is a Seagate Hybrid. Until this problem is solved we've been obliged to return the machine to Snow Leopard. The external drive is a Seagate Barracuda 3TB with three partitions. All three partitions show up on the desktop. The enclosure is a Pleiades Firewire 800.

Choose Preferences from the Finder menu, click on General, and check the settings. If they’re correct, choose Utilities from the Go menu, open the Disk Utility, and if the drives are listed in gray, mount or repair them.

To Upgrade or Not To Upgrade (From External Hard disk to Internal Hard Disk

Hi, need some advise here.
Currently I have a External Hard Disk (320GB) connect with my IMac with Internal Hard Disk of standard 80GB.It is ok just that have to power on/off the External Hard Disk. It is very common that I forgot to power on the External Hard Disk and my iTune library goes to other location in the Internal Hard Disk instead of follow my setting in my External Hard Disk.
So I am considering remove the standard 80GB in my IMac and change with the 320GB.Read some instruction/procedure on this to me look complicated with the thermal pad thing so now hesitating worth the risk to swap the hard dsik or just leave it as it is.
Leave it as it is or change it?
Any advice ?

Here's a link to a take-apart guide I used a few times to replace & upgrade drives & memory in my old G4.
http://www.xlr8yourmac.com/systems/iMacg4/imacg4takeapart.html
No it's not as easy as opening up a pc, but the key word is patience. The key thing to remember is to make sure you get some heatsink paste from your local computer store, and apply it to the areas that need it before buttoning everything back up.
It'll only take you a few hours if you work carefully. While you have it open I highly suggest upgrading your upper memory stick, as well as upgrading your superdrive. I get all my stuff here, they haven't steered me wrong yet:

MacBook does not see internal hard disk

Sorry if this is already answered somewhere, but I have searched so many forums that my head is swimming!
My boyfriend connected a new USB drive to his MacBook, formatted the new disk, copied some backup data onto it. At some point, the MacBook hung, so he held down the power key until the MB turned off.
Each time we restart it now, we get the flashing-folder-with-question-mark, and Tiger won't boot.
I have tried almost all of the tips I can find, and was even willing to reinstall OS X, however... the MacBook does not appear to see it's internal hard disk. As such, I cannot perform first aid on the disk via booting to setup DVD, and I cannot reinstall OS X.
If I boot from the OS X install disk, and use Disk Utility, the MB only sees the CD-RW/DVD-RW drive and the install disc. No internal HD ever shows up.
Help! I am at a loss as to how to fix...

Let me guess: you're also experiencing a low clicking noise from the right side of your mac immediately after you turn it on, right? Same thing happened to me and others, in fact there are several threads on this subject already:
http://discussions.apple.com/thread.jspa?threadID=960977&start=0&tstart=0
http://discussions.apple.com/thread.jspa?messageID=5325539&#5325539
My drive was done for, and no data could be saved. I ended up buying a new drive, and now I'm just hoping the same thing doesn't happen again. I'm beginning to get a sense that this problem is occurring on a more frequent level now that the 1st generation macbooks have reached their 1-year birthday, give or take. Let's hope Appel fesses up if it is indeed a design flaw.
Anyway, you most likely need a new drive. I just got a Hitachi Travelstar 250 gb for around 200$US, so they're quite cheap, and VERY easy to install, just 3 screws, slide it in, boot up, run disk utility, erase/format and you're good to go.

Can't repair or partition internal hard disk with disk utility

Hi,
For the past couple months I've been trying to repair and (re)format my second internal hard disk. It stopped showing up on the desktop after I attempted to install leopard on it. Until then I'd had no problems with the disk for the two years I've had it Leopard installed fine on the other smaller internal disk. But the second disk only shows up in disk utilities - it doesn't have any volumes. I can't verity the disk because the button is greyed out as is the repair disk button.
S.M.A.R.T. Status shows "not supported".
Partition Map Scheme shows "unformatted".
Whenever I startup my computer I get a dialog box stating "The disk I have inserted is unreadable by this computer". I't referring to my 250gig internal disk. I read some posts here that suggested using OS 10.4 disk utility to format but that doesn't work either.
At this point I'm totally lost as are all the files I had on that disk - I initially erased it back when I attempted to install leopard on it. Does anybody have any ideas how to fix this?
Thanks for any and all help

Hi V.K.
Thanks for the advice. Luckily I don't have any data on it since I wiped it clean back when I attempted to install leopard on it a couple months ago. I'm really amazed that it only lasted two years compared to my 80gig which has been in use [daily] for at least five years. I hardly ever used the 250gig drive. I ordered another (500gig) drive from Western Digital which I expect to be here in a couple days. In the mean time I guess I'll get out my hammer.
Thanks for your help.

Firewire drive not visible on desktop

Firewire drive not visible on desktop
System profiler knows it's there.
Disk Utility indicates that it can be un-mounted (only a generic 'turned down page' for volume icon however), Disk has full Hard Drive logo...
But I cannot access it on this machine, but plug it into another and it's ok...

(only a generic 'turned down page' for volume icon however), Disk has full Hard Drive logo...
You can see that appearance in Disk Utility if the volume permissions are such that the current user has "No Access."
Since it can be accessed normally from another machine, connect it there and do a Get Info from Finder, looking at the Ownership and Permission Details at the bottom. Assuming this is not a startup disk, if any of the permissions is set to "No Access", change it to "Read and Write". Don't click "Apply to enclosed items" however.

How do I move music files from the startup disc to iTunes in the other internal hard disk os 10.5.8?

How do I move music files from the startup disc to iTunes in the other internal hard disk os 10.5.8?
The music I want to move was in iTunes but is now just files. I had to reinstall a new iTunes and lost all my old music.
Thank you!

That article is about using your iPod as an external hard drive, to move files from one computer to another computer. It is not related to your question.
You can't use iTunes to move song files from iPod to computer, except for songs you purchased from the iTunes Store (and you can also re-download purchases). However, there are third-party methods and utilities that can move song files from iPod to computer. If you do a Google search on something like "ipod transfer," you should get some links.
Once the song files are on your current computer, add them to that computer's iTunes library by dragging the files (or folder containing the files) to the iTunes window. After confirming everything is there (and fixing the data issue you mentioned) you can sync the iPod. You may want to do a Restore on the iPod, if it might have a data corruption issue, which will erase the iPod's hard drive, re-install the latest software, and set it to defautl settings.

Re: How can I add a second internal hard disk to a Satellite Pro P200?

I have a Satellite Pro P200 with a single internal hard disk. There is a second bay under the computer for another internal hard disk but I have not been able to find any information about it. There is enough space for a 2.5" SATA drive but I cannot see a connector.
I contacted Dutch Toshiba Customer support who said that it was the official policy not to provide any information about a second hard internal disk. They also said that they would not supply any parts to make it possible.
Can anyone provide some more information?

Hello
I have the same notebook with the same situation. The fact is that covers and the construction for all P200 notebooks is the same but notebooks are delivered with different hardware platforms. Some models are delivered with two HDDs.
Other models (like yours and mine) are delivered with one HDD but without possibility for upgrade with second HDD.

Hard Disk Not Exist help please

Hi, not sure if this should be in Recovery or Hardware or Operating Systems as it involves all three!
I have an HP G61-110SA running Win 7 64 bit; product no. VR523EA. Also have serial no if needed. One problem is, as the laptop is 6 years old, it's hard to remember what came with it.
Whilst using on Thursday it suddenly froze and ctrl/alt/del didn't respond so i held down the power key to turn off. When I rebooted, I got "PXE-E61 Media Test failure; check cable. PXE-M0F: Exiting PXE ROM. No bootable device -- insert boot disc and press any key".
I don't have a boot disc as the OS came preinstalled. So here's what I've tried so far by reading other similar problems in here.
- Ive taken out the HDD and reseated it. Reboot then said Hard Disk Not Exist. Tried reseating again. Same message.
- Created a bootable Ubuntu CD and ran that - no response.
- Created a Ubuntu bootable USB and that has worked except Ubuntu isn't showing the HDD so I can't retrieve anything.
I can however connect my wireless network and at least use Ubuntu in the meantime.
I've ordered a new (same) replacement HDD (a Hitachi 320GB 2.5"). So next problem is how to reinstall Windows 7 without a recovery CD? Did the old HDD contain the recovery partition drive or would that be located elsewhere thefore still be accessible when the new HDD is installed?
If not, I'm assuming I can still purchase recovery discs from HP? I know I should be able to create my own recovery discs however, the MS sticker on the bottom of my laptop beside the laptop details, has become too faded to read the important bits! All I can see is "Proof of License, Certificate of Authenticity, Microsoft Corporation 2005" and "Label not to be sold seperately". Any letters/numbers are long gone. So would I be able to find these any other way? My friend (an IT Manager) said something about DBAN being able to read all that from the HDD but not if it's fried?!
Next problem - I was also using Office 2007 (think it was Home Premium). Either this came preinstalled (unlikely?) OR it came with a 30 day trial which I could purchase the full version & download the full version from online using a link within the trial? I think this is what I did because I have no other way of obtaining Office for Windows 7 and yet whatever version I had, had about 3 user licenses because I also installed it on my son's netbook. I do have Office XP discs for my previous desktop PC (but couldn't have used those surely on Win7)?
And just to add a gripe .... although I certainly got my money's worth out of my old laptop, I'll now have to buy a new one - which I consider a treat - BUT I'm choking at the expense of replacing all the software I need! Anything I buy new will be Windows 8 which none of my old software was compatable with - same as when I have to previously rebuy it because none of my XP software was compatable with Win7! But on the plus side, I'm assuming if I install my new HDD on my old lappy, I can also install Ubuntu to the new HDD so at least my 11yr old son can browse and surf on it via Ubuntu.
Can anyone answer/help with any of the above problems? Many thanks in advance.
This question was solved.

No way to free space in the internal hard disk.

Hi guy
There's no way to free any space in the internal hard disk. If I throw 5 giga of files in the trash and empty it, I don't find 5 more giga of avalaible space in the internal hard disk. Time Machine is not activated. Any idea to solve the problem? Sorry for my english....

Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

Is it possible to upgrade the internal Hard disk drive on the iMac

Is it possible to upgrade the internal Hard disk drive on the iMac?

Yes but it's definitely not advised. If you have a machine newer than 2009 Apple uses drives that have integrated heat sensors. This makes upgrading much more difficult but not impossible. If you have a machine still under warranty then definitely DO NOT do this yourself as you may void the warranty not to mention it isn't for the faint of heart. Take the machine to an AASP to have the work done, you will need to find one in your area willing to do so.
If you are considering a new machine then simply buy the configuation you need.

Hp mini 110-3518cl windows7 starer is displaying hard disk not exist

Your friend did the pretty much standard procedure to see if any files can be read and retrieved from the failed hdd. There are data recovery companies out there but they aren't cheap. It is always advisable to have an external usb hdd for backup.
All hdds fail after time ,though laptop hdds seem to have a higher/faster failure rate due to the confined case and extra heat. SATA hdds seem to die much faster than the older Ide type drives in laptops and desktops from what I have seen.
Not uncommon to see posts about a laptop hdd dying after 1-1 1/2 years,though I have been fortunate with mine which is 3 yrs old. I do use a laptop cooling pad under mine which may contribute to it's longer life.

Hard Disk Not Exist! help pls!

Hi techies,
I was using my hp compaq when I froze. I did powered it off and restarted only to be confronted with "hard disk not exist". I tried to run diagnostics on the hard disk as directed by the functions buttons and it kept say stuff, "install operating system for hard disk". I've met a guy who knows stuff about such n he says my hd is fried and I'll have to get a new one. I'm kind of surprised as the laptop is barely a year old. He took out the hard drive and put in an external drive enclosure and on connecting to another computer, he couldn't get a read on the hard drive.
My questions are;
- is it possible for me to retrieve all my files from my hard disk? It'll be like going back to the stone age to try to start afresh. If it is, how? If not all, what kind of files can I retrieve and how?
- what is the cause of this damage to my hard drive because my system gave me no warning.
Pls, reply asap.
Thanks guys.
