System not seeing new 36 drives - on Ultra 2

Anyone,
I have a Sun Ultra 2 that was upgraded to dual 400MHZ CPU and 2 GB of memory. I also purchased two new SCSI drives that are 36 GB in size. I have installed one of the drives in target 0. When I start Solaris 9 install I can go into format and it sees the drive. I have formated one of them and install the Solaris 9. When I put in the other drive I can run the install program and format the second drive, and I can partition it, save it, etc. after a reboot, I go into Sun Management Console and try to mount the drive SMC does see the second drive. After I shut down, I do a probe-scsi-all and it does not see the second drive and the screen lists the first drive and then flashes to the CDROM listing. I think this is because of an control character on the disk description. Why would probe-scsi-all not see the second drive and format will see the second drive. Also I have a HP 18GB drive that I have formated and the system can not see it either. Do you know of a jumper that needs to be set. I can see not jumper on the hard drives. Format can see the drives so it must be something with the OS. One more thing, I did not let the validation run to the end when I was formating the second 36GB drive, but I have cntl-c out of it after the first pass but I have done that before on other drives without any problems. Any ideas why the OS sees only one drive and not the second disk.
Thanks for any help. Richard

From the sun hand book it looks like the Ultra 2 doesn't support 36GB drives
Up to two 3.5- x 1-in., 2.1-GB, 4.2-GB, or 9.1-GB
18.2 GB maximum internal (two 9.1-GB disks)
That's not to say they won't work - but you may find that the reason you're getting odd responses is that while they will work they're not fully recognised by all the utilities...

My new mac mini does not see usb drives, but in hardware info the usb is visible

my new mac mini does not see usb drives, but in hardware info the usb is visible
i'tried several usb flash drives even brand new ones, they are visible onder hardware info but they are not on the desktop nor in the finder.
what is wrong and doe anyone has a solution ?

It does not show up in disk utility, its only visible through systeminformation.
When you plug in the USB flash drive and then refresh systeminformation it becomes visible.
To remove it I shut down the computer because I cannot eject the USB device anywhere.
After starting up again when I have removed the flash drive it has gone from the systeminfo USB list.
By the way my USB mouse and keyboard are working fine, I also changed ports of these and they still keep on working so I don't think the USB ports are defect.
I guess it some kind software problem, and because I'm new to Apple I do not know much about it how to solve this.

Windows 8 does not see hard drive on Satellite A200

Windows 8 does not see hard drive on A200.
How to install?

> with Vista works fine,
Does this mean that Vista is still installed or is HDD visible while Vista installation setup?
Some notebooks HDD controller needs SATA driver in order to be able to install system.
Sat A200 is a little bit older but I dont think the SATA driver is needed here to install Win 8.
I guess you didnt any SATA drivers to install the Vista right?
Set the BIOS to default and try to boot again using Win 8.

Why in SE16 we can not see New Data Table for standard DSO

Hi,
We says that there is three tables (New Data Table, Active Data Table and Change Log Table) of Standard DSO, Then Why in SE16 we can not see New Data Table of Standard DSO.
Regards,
Sushant

Hi Sushant,
It is possible to see the 3 DSO tables data in through SE16. May be you do not have authorization to see data through SE16.

I'm attempting to transfer files, address book, etc from an external hard drive to my new Mac-mini using migration assistant. The external drive is showing up on my desktop but Migration Assistant is not seeing the drive when searching for devices

I'm attempting to migrate files, address book, maile, etc to my new Mac Mini using an external hard drive and Migration assistant. I followed the instructions on using Migration Assistant to do this but Migration Assistant is not seeing the external drive, which is displayed on my desktop

I've been chasing this problem all afternoon. I had to reformat my internal drive on my MBP and reinstall Mountain Lion Start up assistant wouldn't see my extrnal drive with the Time Machine files on it. After many tries, I skipped the restore there and let the system boot. I could see my external drive from Finder and the files looked OK. I was told to use Migration Assistant and it had the same problem.
I saw a hint on one of these posts that the icon that you see and is label Macintosh HD is actually your backup disk and it is telling you that it has a copy of your internal Macintosh HD. I went ahead and told it to continue and it started to restore my apps, settings, and documents. It's been going for a couple of hours, and is close to being done. I expect to see my old system restored when it is finished.
Wish that Apple would put some type of note that it is seeing the backup. That is most confusing and seems to be a problem for lots of users.
It's been a month or so since your post Did your get it to work?

PowerBook G4 does not see optical drive in System Profiler

I have a very strange situation in a powerbook G4 (1.67ghz, hi-res 15" screen).
I bought the laptop non-working, installed a new power board (plug on old one was fried!) Installed a 250gb HD which I had installed OSX on in another G4 laptop, and it booted up fine, or so I thought.
When I put in my Leopard install DVD to install over the existing 10.4 Tiger, the disc spun up, but would not mount - would not eject - and when I checked the System Profiler the superdrive was not recognized by the powerbook as being present on the ATA bus. The hard drive, of course, was seen on the ATA bus.
I thought the superdrive was bum, so I installed a known-working combo drive I had around from a previously parted laptop (Apple branded) and experienced EXACTLY the same situation.
Other things I have tried included using jumpers to manually set the hard drive to slave and cable select (from the factory, with no jumpers, it is set to master), thinking that perhaps the optical drive was somehow seen as master or cable select. All possible jumper settings I tried made no difference.
Booting from external firewire hard drive shows exactly the same situation on the ATA bus, EXCEPT (and this is where it gets just weird enough to pique my curiosity and keep me trying to fix it) - When I boot from the external drive WITHOUT AN INTERNAL DRIVE installed, the SUPERDRIVE SHOWS UP ON THE ATA BUS of the System Profiler! I have not yet seen both at the same time, but I can get one or the other to show, depending on, apparently, the presence of the internal hard drive.
Am I missing something here, or am I to assume a fault in the IDE controller of the logic board?
I have never seen this laptop working properly, but the seller I acquired it from stated that the optical drive worked fine until he fried the DC in-board, presumably with a faulty power supply. He had removed his hard drive to save the data on it.
Thanks for any help or clues that anyone might provide.

Well, I am happy to report that the situation is resolved with my powerbook not seeing the superdrive, but I still do not really understand exactly why it was unavailable in the system profiler as I originally posted.
My particular solution was to wipe out (erase) the hard drive, zapped PMU, zapped PRAM, did the reset-nvram in open firmware, rechecked to make CERTAIN the proper cables were installed properly, and Now I just completed a fresh install of Leopard from the previously recalcitrant superdrive, to the now-clean hard drive.
My BEST GUESS as to what was wrong with the situation from the outset may have had something to do with where the hard drive came from and how that operating system was installed. (the OS was on the HD when I installed it) In hindsight, perhaps doing all the resets, as well as repairing permissions MIGHT have done it, but I got caught up in thinking it might be cables or something.
So, I would advise others with a similar problem to:
repair the hard drive
repair permissions on the hard drive
reset PMU
reset PRAM
boot to open firmware (hold command-option-o-f at boot) and type "reset-nvram" (without quotes) enter, the type "set-default" enter, then type "reset-all" enter
cross your fingers, knock on wood, and boot! See what happens....
if no glory, THEN look at cables (make certain they are the CORRECT cables and that they are seated properly) I bought a hard drive cable and an optical cable from ebay sellers with assurance that they were the proper cables, and NEITHER had the same part number as the original cable which I suspected faulty, and that in the end are actually GOOD! GO BY PART NUMBERS! do not accept someone elses assurance that their cable is the proper one!
then suspect faulty optical drive - if possible swap another drive in and check.
if a second optical fails, then SUSPECT logicboard, but before you invest in a new logic board ($$$$$) try putting a freshly erased HD in and just see if that helps.
good luck to you all with your mac troubleshooting!
and thanks to all who read and pondered....
I will mark this case "answered" though it is more closed than truly answered.
I am very relieved that the fault did not lie in any of the major components (or even the minor ones for that matter)
It turned out to be only software/installation/settings, even though the symptoms certainly seemed to point to a hardware issue. It pays to try the resets and repairs!

Macbook does not see new hard drive

I have one of the first black macbooks...
Intel Core Duo
2GHZ
2mb L2 Cache
2GB RAM
667 MHz bus
Boot ROM Version: MB11.0061.B03
SMC Version 1.4f12
I had an 80GB HD in it that has died. I decided to replace it with a WD Scorpio Blue 160GB.
I've booted to the optical drive and went into Disk Utility to format the new drive but the computer would not recognize the drive. So I formatted it with another computer using a USB enclosure. I put the new HD back and still not recognized.
I then went ahead and installed Snow Leopard on the new drive via USB enclosure, using the macbook I would eventually put the drive into.
Now when I put the new drive, with the OS installed, still not reco

Let us resume the required steps, after putting inside a new, virgin disk:
1. Start up machine and as soon as possible put CD/DVD, press key C to force boot from CD; if the sequence is not fast enough and machine passed over the initial phase, and ? was displayed, force shut down by pressing button key, then start again, with CD/DVD inside
2. Press key C after start, and wait until the Apple logo in displayed, wait
3. You will see a list of install language, choose one, and
4. Go to Apple bar and choose Disk Utility; on the left side, you will see the disk, select it, then, on the cenral-lower part of displayed windows go to Options and choose Apple Partition Map (APM), go back and choose, if not already chosen by default, Mac OS Extended Journaled (HFS+), 1 partition (or more, some prefer more than one), click to partiion/erase disk. Note that you MUST have both conditions achieved: APM and HFS+
5. Close Disk Utility and revert to installation proper, proceed.
If you do not see the disk on the left side of Disk Utility, then disk is damaged or badly connected.
P.S. The same procedures are applied to any disk, with the note that:
- for Intel Macs, partition map should be GUID, not APM
- for external disks or flash drives intended to smoothly work with Windows, format should be FAT 32 and Master Boot Record; NTFS may be done with an additional utility like NTFS-3G or NTFSmounter

New Airport Extreme (2014) does not see USB Drive

Just fired up my new 2014 Airport Extreme and attached a Toshiba 3 TB USB Drive. My new (late 2013 iMac) does not see the new drive in Disk Utility.
The Extreme works in all other ways; ie, as a router, as a wireless node.
It came to me formated as a Windows drive, so I attached it directly to my MacBook Pro (which saw the drive) and reformated it as a Mac Drive (Journaled, GUILD). It showed up just fine on the MacBook Pro desktop.
When I reattach it to the Airport Extreme, it still does NOT show up in Disk Utility on the iMac.
Help Please

When I reattach it to the Airport Extreme, it still does NOT show up in Disk Utility on the iMac.
That drive will not show up in Disk Utility on the Mac.....since the Toshiba hard drive becomes a network drive when it is attached the AirPort Extreme.
Disk Utility will not display a network drive. It will only display drives that are connected directly to your iMac via USB, FireWire, etc.
Check using AirPort Utility to see if the AirPort Exteme recognizes the drive.
Open AirPort Utility, click the AirPort Extreme icon, then click Edit
Click the Disks tab at the top of the next window that appears
The drive will appear here if it is recognized by the AirPort Extreme.
In the example below, my WD Drive is connected to the USB port on the AirPort Extreme.

[SOLVED] New install does not see SSD drive

Ok, I have a DFI motherboard which at first did not recognize my new Intel SSD drive I have installed. After updating the BIOS, it now correctly recognizes it. However when I run the 2009.2 cd and try to prepare the drives, it does not show any drives listed?
/sbin/fdisk -l
does not show any drives either so it looks like arch cant see any installed HD's which makes since, but the motherboard does show the new Intel SSD as a Sata drive right under my DVD player?
Any help?
Edit: I hooked up my old Seagate drive and it shows up fine. Any idea on why this SSD is not playing nice?
Solved: I have come to the conclusion this has nothing to do with the Arch install, but is simply a hardware issue with my motherboard. I installed the SSD drive in my wifes pc, it seen the ssd as a sata drive while booting, it seen it when arch was initializing, it seen it when I did a fdisk, and when i finally tried to install, it was there too!!
So there must be some issue with my old DFI MB. I will work on that or upgrade..Thanks to everyone who helped out...

I had trouble with my throttle device not making contact with the data lines when connected to USB.
I assume the SSD has the same connector as the motherboard and the cable can be reversed end to end to test for performance.
I use a multimeter to verify the presence of power to the device.
Sata cables are known to be flaky.
Throttle devices use 5vdc power from USB connector and are connected to esata cables at the same time since sata ports do not supply power. The connections for throttle are on opposite ends of the device.
I am not familiar with the SSD power setup but assume it is 5vdc as well.
No other suggestions here..................
Yes, the cable should be able to be reversed as the ssd drives are identical compared to normal sata drives in respect to the cable connections: one sata data connection and one power. I will try some different cables and see if that helps. I did try a new port on the mb which did not work, and when i used the current cables on my older seagate drive it worked fine

Win7 install does not see new hard drive (640gb Samusung) on MacBook Pro

Replaced MBP 5,4 (mid 2009) hdd with a Samsung HM641JI 640gb drive. OS X installation went fine using SL install disk, updated software to 10.6.4. Problem is with Windows 7 installation using Boot Camp. Partition is created (tried 32 to 300 gb). Windows 7 install disk loads but after "Install now" and accepting license agreement, it does not recognize the drive or any partitions. XP install works fine. Had same Win7 problem with 2 identical hdds and 3 different install disks which were full version, not upgrades. Installed Win7 using boot camp on 320 gb Samsung drive (also 3.0gb/s SATA) without a problem. Tried formatting the bootcamp partition on the 640 gb drive to NTFS, but still not recognized. Any suggestions?

Odd you can't see anything. I'd use Windows 7 recovery tools to do a full initialize and map out bad blocks if necessary. Or initialize from OS X drive and then do full slow format etc from Windows DVD.
Every drive vendor has their own linux/dos/windows utility to recertify and test sectors and does a better job than anyone else's. WD Lifeguard for all my WD drives, can be very handy.

Not seeing hard drive

I have 3 hard drives in my mac pro, all internal, which have been fine up until a week ago, now for some reason Drive 3 seems to not show up sometimes.
I see it on the desktop, but then if i go to open a file from it, say an mp3, it doesnt load it. It says the file is 0 bytes.
Other times the drive simply isnt showing up at all.
I have to restart the mac and its ok then.
Anyone have any ideas or help on this problem?
Thanks

you need to off load files, you need to erase (zero or 3-way) or look for scanning the entire drive, not just user volume, for bad sectors.
So having a solid system drive, and backup, and not lose files.
new drive? warranty or another issue. I didn't see you say this new drive you just added and what make/model etc and focus on that problem.

After unsuccessfully updating to Yosemite, back on Mavericks. But now my Timemachine or system not recognizing the hard drive. Is there any way to manually locate or find the hard drive?

Hi kruione,
If you are having an issue with an external drive not being detected by your iMac, I would suggest resetting the computer's parameter RAM. See this article for how -

Disk Utility not seeing new hdd; how do I fix this?

MacBook Pro Model A1278 (EMC 2326*) 2010. The old hard drive failed so I purchased a WD SATA 500GB. Model is WDBMYH5000. Im using a install DVD of Lion to try to format the new HD.Disk Utility or the OS X installer will not see the HD. I have searched several threads but have not been able to locate a definite answer. I have made sure to install properly. Also found a thread that referred to clearing the NVRAM and firmware. No luck with that either. Is there a way to format through terminal? Do I need to do something with the jumpers perhaps?

If you toggle Airplane mode On/Off, does it resolve?

Mac Pro Hexacore does not recognize new drive

I have just received my new 2 TB Seagate constellation drive and the mac pro hexacore running OS X 10.6.7 does not recognize it. From touching the drive it is warm and feels like it is running but nothing shows up on the desktop and Disc utility does not see it at all. Since this is the highest quality drive with a 139 year MTBF it seems infinitely more likely that something is not right in the mac than in the drive. In the past adding new drives has been simple enough but this one is not even showing up. Ideas?

Actually I had ordered 2 of these drives and at first I thought it was an Apple problem but I put the second drive in and it worked perfectly, so the first drive must have been DOA. Thanks for the reply. I just wanted to make sure I had not forgotten to do something to make the drie be recognized.
Thanks

V480 not seeing internal drives - no LED's on the drives either

Hello,
I purchased a used V480 from eBay which came w/o drives. I had to buy separate drives from another vendor. The system appears to be fine - i.e. I am on the console, all tests pass, probe-scsi-all "sees" /pci@9,600000/SUNW,qlc@2 (but not the drives), and I can start an install of Solaris 10 booting from the CD.
So at first I thought it was the drives were bad, but the three LED's next to each drive do not light up ever - not during POST or anything. Doesnt matter if the drives are in or not.
My question(s) are - shouldnt those LED's light up/flash at least once during POST regardless of if the drives are in or out? Also, I dont have the key to the machine (anyone have a spare they want to sell me? <grin>) so I cannot put it in diagnostic mode. Does anyone think that matters i.e. if I could put the box in diag mode, install the drives and boot would that maybe help to "see" them?
The machine shipped w/o drives to me so my final question is - is there some sort of configuration or jumper internally that could "block" the drives being seen i.e. the original owner used only external FC-AL drives and so they did something to make it so that internal drives could not be used lets say for security purposes or something? Not sure where else to troubleshoot but I dont want to try and return the machine - too expensive to ship it back.
Appreciate any suggestions.
Cheers,
dave

Nevermind. Figured it out. The drives were not stock V480 drives. They were Hitachi drives pulled from a StorEdge 9900. I had to "jumper" them to get them to spin up. Once I did that, they were seen by probe-scsi-all and now I can format them and use them.
Cheers,
dave
