PowerBook 145B - strange hard drive interface?

I opened up a PowerBook 145B from a friend that had died (the PowerBook, not the friend) and pulled out the hard drive to recover the data. I thought I would find some type of regular SCSI interface on the hard drive, but...
I've spent some time Googling and found people who can't figure out how to get data off this drive (IBM Model WDS-2120, 120mb) and no solutions. It says 2.5" SCSI 17mm on the drive, but the interface is something I haven't seen.
Does anyone have ideas on how to get the data off this drive?
Thanks!

Hi,
I don't think a cable exists which would handle the data and power requirements of the WDS-2120 and allow connection to a more standard SCSI interface.
The adapter that I have is part of the external case mentioned above. It has made it possible to supply power to e.g. a WDS-2120 drive, and to connect that drive to the HDI-30 SCSI port of a PowerBook or the DB-25 SCSI port of a desktop Mac. However, as indicated, it may be difficult to buy something like that today.
(It looks like 8 of the pins are for power on the HD.)
If I remember correctly, the ID selector is connected to some of the pins in the separate group of eight. Since the internal hard drive always is ID 0, the selection can even be simplified (meaning that the complete interface may not be needed). So, do not be surprised if you see a connector covering merely the main portion of the interface in some computer models.
For more on pinouts, try a Google search for this or any other (maybe Quantum) 2.5" SCSI hard drive. Also, you may be able to find something of interest in the Apple hardware documentation here.

  • VME PCI-6200 hard drive interface cable identification

    Hopefully someone on this forum still uses the VME PCI-6200.  I'm looking for a replacement hard drive interface cable, 50-pin female-female, connecting a 2.5" PATA hard drive to the PCI-6200 board.  Does anyone know the cable standard or where a replacement can be gotten?  I'm enclosing pictures and the board spec for identification purposes.  Thanks!

    According to this website I found      http://www.pc-pitstop.com/scsi_adapters/
    It is an IDC 50 connector. 
    I briefly tried to find a retailer that sold them, but had no luck.

  • Macbook Pro 6,2 hard drive interface

    Far as I know that newer macbook pro have hard drive interface 1.5gb/s and older Macbook pro model have 3gb/s interface. I was wondering if I can change the hard drive interface into 3gb/s? I finish order new hard drive Western Digital 500gb 7200rpm with 16mb cache and there is a link if you want more information about this drive.

    thanks!

    oh really!? That a relief haha. Im not a big fan of Hitachi drive and Im a big fan of Western Digital when it come to performance and reliability . I notice the performace was stuggle when Im using Window 7 for my bootcamp. This new hard drive willing to improve the performace!

  • [SOLVED] Strange Hard Drive Errors - Read Only Filesystem?

    Solution: Discard old laptop, buy new laptop
    I have an Acer Aspire 5103WLMi. For about 2 months now, Arch has been running smoothly. Until 2 weeks ago.
    It all started when I tried to install and configure autofs on Arch x86_64. On the next reboot, all manner of errors were printed to the screen, to the effect that the internal hard drive was only being mounted read-only, rendering the system unusable. I tried to find a solution, but there were no references to read-only anywhere; fstab, grub etc. None that I could find.
    I tried reinstalling. However, x86_64 Arch refused to boot properly first time due to the exact same error; and I *know* that I'm configuring everything correctly. I managed (somehow) to coerce i686 Arch to install, and things "work".
    Seemingly out of the blue, during normal operation, all running applications will stop, and spit out error after error to the effect of "Cannot Write to Read Only Filesystem!". Sakura won't load (Input/Output error, apparently), and the only way to shut down the laptop is a hard reset (I can't log in as root or use sudo because it wants to write to the filesystem first, which it obviously can't.
    Now, I'm going to be giving the insides of this laptop a good cleanout this weekend, and I'm in the process of backing up all of my data, but I was wondering if anyone else has come across a similar form of misbehaviour; or (with a bit of luck) some potential solutions?
    This is very peculiar, because there seems to be no reason why the laptop suddenly loses write permissions to the hard drive. Cheers.
    Edit: I think I should point out that my /boot partition is Ext2, and / and /home are Ext3

    Additionally, somehow I have now been able to install Arch x86_64, but the problems still occur...

  • Best Portable External Hard Drive Interface?

    I have a MacBook Pro (just got it this year) and I need a portable external hard drive. I also want to use it on my PC. Which interface would you suggest? I am not sure which connections my PC has but I know it has USB 3.0. Is there an interface on my MacBook that's faster than USB 3.0? If so, I might forget about connecting it to my PC, assuming it's significantly faster.

    Likely a combination Firewire 800/400 USB 3 drive.
    Mac's don't have USB 3 yet, only USB 2,1, so you can use the Firewire 800 with your Mac and the USB3 with the PC. The USB 3 is backwards with 2,1 on the Mac too, in case you forget the 800 cable.
    See the formatting guide here
    https://discussions.apple.com/docs/DOC-3044
    There is also Thunderbolt on the Mac's, it's REALLY fast, but you need a internal and external SSD to get anything out of it, your hard drives would be the bottleneck and you would be paying a lot of money for speed you can't use.  In the future when the price comes down and SSD's are cheap and of large capacity it would be a nice interface to use.

  • Hard drive interface for new dv7t-7000 quad

    Hi.
    I just want to know the hdd interface for the newer ivy bridge dv7t-7000 quad laptops.
    Does anyone know if it is SATA, SATA 2 or SATA 3?
    Thanks

    I run three firewire audio interfaces daisy chained together, 2 Presonus FP10's and an Alesis Multimix8.
    This gives me 24 simultaneous inputs. I normally record 24 bit at 88.2 . My iMac has a FW800 and a FW400 port. What I tried to do was run all the interfaces through the 400 and record to a FW800 external hard drive but I it kept dropping out interfaces, even if I used only one interface. I switched firewire cables on the hard drive to a 800/400 so that the hard drive was now operating as a 400 and I did not have any more interface drop outs.
    Even though the iMac has 2 firewire ports, they connect to a single cable to the i/o inside the Mac. If I try recording to an external hard drive, that is 24 tracks going into the Mac, back out to the hard drive, back in to the Mac and then back out to the interfaces and on to the monitor speakers. That is a lot to ask of a firewire connection.
    So, I record to the internal drive and use the external for backing up and saving the projects.

  • Hard Drive Interface

    I'm looking to purchase an internal hard drive that I will put in a case to make an external drive for my system. Based on the specs of my powermac is there a specific type of hard drive I will need to buy for it to be compatible? Should I get SATA or ATA? Any other issues that I may run into while looking for hard drives? And any suggestions on what drives you would recommend, thanks.

    Do you know of any good pci-controllers that have
    support for multiple external harddrives? Any
    personal suggestions? and what kind of interface
    would the multiple ports on the controller use?
    Dear Chris,
    Since you have a dual core PowerMac G5 you need a SATA PCIe host adapter. If you want to support more than two hard drives externally I would go with the Sonnet E4P. You can read more about it here:
    http://www.amug.org/amug-web/html/amug/reviews/articles/sonnet/e4p/
    The E4P will support up to four individual hard drive connections or it can support SATA PM enclosures that support up to 5 hard drives per enclosure. Up to four 5-bay enclosures can be connected to a single E4P. It's a very nice card but expensive at $299.
    The other SATA 2 port external host adapter I would recommend for the Dual Core PowerMac G5 user is the FirmTek SeriTeK/2SE2-E
    http://firmtek.com/seritek/seritek-2se2-e/
    This new PCIe card is only $99.95 and provides two external ports. FirmTek does not advertise that the 2SE2-E is SATA PM compatible as the SiI-3132 chipset has a bug that limits this card to a maximum of 110MB/sec. when a single port is used with a 5 bay SATA PM enclosure, but it does work with SATA PM too.
    This card is the best little two port available for the PCIe Mac user. It uses FirmTek's great firmware instead of the Sil-3132 1.04 Mac driver. In addition, the 2SE2-E will be bootable with a firmware update. The FirmTek SeriTek/2SE2-E is a great value option that can provide a very fast dual drive striped RAID set or individual SATA connections for PCIe Mac users.

  • Hard drive interface 6 Gb/s

    Just posting my experience for others not to get caught in problems as I did recently.
    Bought a Western Digital 6 Gb/s one terabyte 64 meg cache 7200 rpm sata hard drive. I installed it in a 2008 Mac Pro to run Snow Leopard. My one thought was it should be automatic,(even though interface is 6 Gb/s) just like all my other sata drive upgrades. The Mac Pro is rated at 3 Gb/s.
    Apple manual reads 3 Gb/s for internal hard drives.
    Used DU to partition in two. Did a DVD restore to the smaller partition. Booted that restore smaller partition. Installed Snow Leopard to the larger partition. All is well so far, I thought. After install of Snow Leopard, it boots into the set up screens and fails at "Do you already own a Mac?' I tried this two more times and repeated the failure.
    Go to WD FAQS and read for the WD1002FAEX (BTW I don't think the brand or model matters when its 6 Gb/s). Word for word: "OPT 1 enabled. Jumpers on pins 5 & 6. 1.5 Gb/s data transfer." I thought that stinks. I'm going to take it back because I'm not settling for the lower rate.
    I broke open the Mac Pro again to remove the hard drive. I noticed the printed text ON THE HARD DRIVE reading " set jumper to 5 & 6 to make 3 Gb/s compatible. I did and all works fine even the set up screen. I do wish the manufacturers would get their story straight on their support site.
    Lastly, I also hope that many of the people on this forum can be more specific when counter measuring (finding the correct answer to a problem) and stop making an assumption that others know the counter measure.
    A community service.

    It may be that the way to make it compatible with a 3 Gb/s computer is to set it to 1.5 Gb/s. 1.5 Gb/s drives are compatible with 3 Gb/s computers, but of course run at 1.5 Gb/s maximum. So the WD FAQs and drive label can be consistent.

  • Dead powerbook with operational hard drive: how to extract the data?

    I've got a very old (2006/7) powerbook which cannot be powered on; the battery is dead and can't be charged due to assorted catastrophic power issues. I've long since replaced it so I'm not really interested in resurrecting it on a long-term basis.  Is there a way to get the data off it? I'm aware I'd have to physically remove the drive.
    So far the only instructions I've found online are for getting data off a crashed hard drive, but that's not the problem here. The hard drive is totally operational, it's just that the computer it's located in cannot be turned on.

    I bought one of these HD adapters http://tinyurl.com/7455nek to get the files off of an old PB G3 hard drive. Worked great and a reasonable price.

  • Powerbook G4 noisy hard drive- is it coming to an end?

    I have had my powerbook for four years and it has done hard work on the road in inhospitable places for most of that time. Now that I'm back home, I've noticed that it has started to sound like a lawnmower (or is that some kind of fan inside?) and it gets very hot.
    Should I be preparing for the worst, or is this normal?
    Many thanks, Rose

    Hello Rose,
    What temperature is hot? Download and install a free widget called, iStat Pro. It will appear in the dashboard and give the operation temps of many parts of your machine. The Powerbook's normal operating temp should max out at around 65-67'C. This is normal! As for the noise: When hard drives start to fail they do get noisy. There is a very distinctive whirring sound as the drive starts up and the machine will become sluggish. There is also the high pitched screaming sound as the drive fails and stalls. However, if you think the sound is just that of noisy fans, it is much more likely to be just that. Have you ever opened the machine and cleaned it? When you do, you are sure to find a major (and slightly disgusting) build up of dust and grit around the fans making them noisy and inefficient. You can try cleaning them although, the noise may not go away because the damage has already been done to the small bearings controlling them, thus making them noisy.
    Should I be preparing for the worst
    Regardless of the symptoms of this event you should always be prepared for the worst when it comes to computers. All computer users should develop stringent back-up plans. I use a collection of large capacity USB flash drives (8GB) as my back-up database. As long as they are stored correctly their shelf life is much greater than that of DVD-R discs (5 years max) and much more stable than an external hard drive (life expectancy unknown and unpredictable). It may be a little more expensive to use flash drives as back-up, but can you put a price on the digital memories of the first decade of your kids' lives?

  • Using an external firewire hard drive + interface at the same time?

    Hi Guys,
    It seems that the issues I am having with BFD2 not streaming properly might be to do with the slow USB transfer rate. (Thanks to everyone who has helped with this issue!)
    So... I am thinking of getting an external firewire hard drive for my iMac.
    Thing is, my audio interface also uses firewire (Mackie Onyx 1220)... can they share using a hub? Will one slow the other down? What if I also run another hard drive on firewire for my audio, will two FW drives and the audio interface all be able to share the one firewire port using a hub?
    At the moment, all my drives have their own direct USB port, is going to shared firewire a step forward or a step backwards?
    Cheers and thanks,
    Mike

    No Interface (yes, I use built in audio), but that shouldn't make a difference in CPU use.
    I have four Internal drives. But that shouldn't make a difference either
    That is very dependent on what you put on these tracks
    I was thinking mainly about recording i.e. 8 simultaneous tracks whilst playing back up to about 16. I generally avoid plug-ins until mixing anyway. Sounds like I should be OK.
    Absolutely.
    but when logic overloads (when the CPU can't process audio in realtime anymore) Logic simply stops playback.
    When I tried using a drive and interface on the same bus a few years ago I experienced minor glitching rather than stopping. Perhaps Logic has been improved in this respect.

  • Strange hard drive sounds

    Whenever I open my macbook the hard drive seems to make a "re-adjusting" noise. It hasn't been acting strangely or erratically, the noise is just a bit unnerving. ANy ideas on what it could be?

    Take a look at this article from Apple, specifically the first option "Waking the computer from sleep."

  • Modifying Powerbooks? RAM, Hard drive? Worth it?

    Hi everyone!!
    Basically I have a Powerbook G4, 12" that I bought new when it came out. So is about 3-4 years old i'd say, can't remember exactly - and I've had to previously replace the CD-RW/DVD drive a year after the warranty ran out.
    My dilemma is that I want a faster mac, but don't really have the cash to buy a new one. I was wondering how you go about improving things like speed, i'm presuming thats RAM? And also increasing my hard drive,as my mac is infuriatingly slow at times. So is it worth the time, effort and money changing all these things, like how would it cost? Or should a buy a new one either macbook or pro?
    I hope i've explained it! Plus the **** keys are coming off it argh - to date i've lost Q,O,G,H, you don't realise how many words have an 'O' until you lose it!! haha
    Thanks in advance for your help
    Tday - mac goddess

    Wow - you're running CS and Tiger in 256mb - no wonder you see things slow down. Looking at your page ins/outs, if page outs are greater than 3163 (10% of page ins), you can use more memory for what you run. In your case, page outs are greater than 3163, so you can use more memory.
    Apple says the max memory capacity in your system is 640MB, which you'd get by adding 512MB (128MB are already on the logic board). So, for example, adding 512MB of memory would cost, from Crucial £30 with VAT. Crucial's UK web site is at http://www.crucial.com/uk/ . To see how to change the memory, see http://www.ifixit.com/Guide/Mac/PowerBook-G4-Al-12-Inch/RAM/53/2 .
    Replacing the internal hard drive is not difficult, but it is technically tedious. You can also view how to do that at the ifixit.com site. You'd probably want to pay someone to do that. You can find an Apple Authorized Service Provider at http://www.apple.com/uk/buy/locator/ . I'd recommend not having an Apple store do the upgrade, as they typically keep your old hard drive. An Apple Authorized Service Provider could do the upgrade for you, instead of an Apple store. In this case, you could have a faster drive installed internally, then put your existing hard drive in an external case and use it to backup files.
    Another option would be to not upgrade your internal drive, rather, buy a fast external drive, and use that as your primary drive. It would have to have a firewire 400 connection, so you could boot your system from it. An example of what you could use can be seen at http://eshop.macsales.com/shop/firewire/on-the-go where a 60GB to 80GB 7200rpm drive costs around $135-$140 (about £70). Doesn't have to be physically larger, and some external drives are larger (especially if they use a 3.5" drive inside). If you go this route, your existing internal drive could then become your backup drive.
    Many vendors offer external drives, so you can find something locally (OWC does ship worldwide, if you ordered from them). While there are various chipsets in the external drives, if they use any of the Oxford chipsets, they'll work fine with your mac. When you buy an external drive from one of the hard drive vendors, like Western Digital or Seagate, they don't specify a chipset, however, they do say they work with a mac.
    So you can spend £30 on memory and £70 on an external hard drive (or around £40 for an internal hard drive and perhaps another £40? for someone to install it) to spruce up your system. I haven't seen Leopard specs yet, however, as Network 23 pointed out, if the 867Mhz CPU is gating your system performance, the fix is a new system, and you probably already know that Macbooks start at £699.
    Oh, and on the keys, have you contacted your local Apple store to see if they can replace them?
    A bit of a lengthy response - please post back with any other questions.

  • Strange hard drive crashes

    Yesterday my MBP crashed, and would not start up. I was able to get it to boot from disk, where the Disk Utility showed no hard drive present. Today, it started up normally. Is there any way to fix this without just replacing it?

    We had a MBP with an 160 GB hard drive fail TWICE! The first disk went out and we thought it might be the disk. Then the second disk went out as well. It was impossible to mount the disk on any computer. I am not sure the FirmWare update was done. Is there a heating issue? SmallDog.com said that the FirmWare update would also address heating issues.

  • Powerbook showing full hard drive!!!after itunes update

    Hi guys,
    Ive got a 80gb powerbook. I recently firewired my itunes library from my powermac to my powerbook. I deleted the old library on my powerbook before doing this. Anyway since ive done this the laptop tells me there is only 2 gb of disk space left. Ive used whatsize to see where it is.
    users: 16.7gb
    applications 6.67gb
    library 2.12gb
    system 1.53gb
    the rest all adds up to about 1.5gb
    and thats it so where as all the hard disk space gone. ive looked at all the posts here but it seems when they use whatsize it shows where all the disk space has gone. On my laptop i cant see any strange files and it shows over 70gb used but it doesnt add up when you go through each area as ive shown above .. please help

    Hi again guys, I downloaded onyx after being unable to find any files of any significant size that would cause this problem. Anyway i deleted the misc options area in cleaning. purely out of frustration to be honest. but hey presto my laptop no shows over 40gb of unused space. dont know what the problem was but thankfully it is now sorted...thanks
