Apple :: Superdrive Read Speed
Mar 5, 2009
I'm recently doing a lot of video editing stuff so...
I burned a video file to a CD and tried to play it off the CD to test it, but the read speed is so slow that it keeps on lagging. And when I try to copy the file back to disk (me and my paranoid testing), it also says its gonna take like 2 minutes even though its only ~160MB.
And when I'm importing a CD into iTunes, it won't go much faster than like 8x.
Is this normal? I'm plugged into the wall if that makes any difference. I ask especially because the rated read speed according to the Apple website is 24x.

I have a brand new Ideapad G710 with 1TB Serial ATA 2, 5400rpm with advertised speed of 3 Gb/s (= 384MB/s). I am running Windows 7 ultimate x64 with SP1.
When I test hard drive read/write speed (I used CrystalDiskMark) I get results of about 100MB/s, which is 3-4 times slower than it should be. I am not running any resource heavy applications (Resource monitor reports Disk I/O to be 0 most of the time in idle state). I have 3 partitions, each with 16-32GB paging file size and all are >90% empty. All partitions have been defragmented before testing.
Is this normal? Are there any lenovo drivers or utilities than I might be missing or that can slow/speed this?

I am pretty sure the optical drive on my MBP is failing as I am having trouble installing software like windows, office for mac, and just burning stuff. So, I did a search here and look it up at ifix it, but I am not sure what is the right model I should be looking at. I have the first gen MBP with the Core Duo CPU. iFix it lists two models UJ-857-C and UJ-867. So, will both work or is one of them only going to work? I know my original optical drive could not burn DL dvds, but it seems like both of these can though?

I just bought a MBA and don't want to pay for an external drive that won't work on any other laptop. Does anyone know if there are any third party external DVD burners that will work with the MBA?

I've realized that I need to replace my MBP superdrive, this is the late 2007 MBP.
I went into About this Mac and then More Info
The disc burning is listed as
MATA DVD-R UJ-857E:
and the only parts I can find on ebay are the UJ-857C

notice the letter difference, since im a n00b at the whole apple parts things i was just wondering if this is the correct part to replace my drive with?

I've been off the forums for quite a while now, but it's great to be back and part of the discussion again. I missed this place!
So I've got a discussion topic:
How easy is it to swap your internal HDD and put it in the SuperDrive slot? Has anyone done this? Can this be done in-house without having to send my computer away?
I'm talking uMBP 15" - the one where you can actually open the battery pack out and flush the HDD (and ram) out.
I'm thinking of buying a SSD for my main (boot) drive and having the 320GB one swapped with the SuperDrive.

It seems most of the people I know who do a lot of burning and use of their superdrive's on the macbook pros are buying external optical drives because the internal optical drive in the mac is failing (not responsive or working anymore).
I'm just wondering, for expensive as Macs are, why is it that this is happening? I thought with the price one could expect high quality parts and not parts that fail within the first two years of owning the laptop.

It's been doing this for a while... Whenever it boots up, returns from sleep, anything, it does this. There is no disk in the drive...

My son's MacBook Pro (15 inch) has a case warp problem that's probably caused by something in the superdrive pushing out the plastic strip on the front of the laptop. I suggested taking it to the Apple Store to see what it would cost to fix (probably a Superdrive replacement at a minimum). I also asked him if he'd like a new 15 inch MBP but he likes his current system despite the problems. It has a Windows XP partition and all of the software that he likes on it which would have to be moved over. I'm disappointed with this generation MBP with the nVidia problem, the failed superdrive and now the current problem.
I have the 17 inch model of the same generation but I haven't had any problems with mine. I'd personally just prefer getting him a new one and I might just go ahead and get one and set it up (he's at a university for the summer and uses his MBP for his job there).
In general, are the Aluminum MBPs more problem free than the previous generation plastic models? Are there fewer Superdrive issues?

Alright so I just want to know if I should be worried or not about this:
Lately, when I open the lid, the drive starts "moaning". You know that sound as if you just inserted a CD or DVD into it. It does it three times with a couple of seconds gap in between.
It still reads just fine, I just tried it with a DVD, but I'm still concerned about the sound.
Usually there is just a small and short sound when opening the lid, just like when booting up, when (as much as I can figure) the head realigns to center.

I decided to get a brand new macbook pro 13" and I'm lovin it so far.
Then one day I plug in my 1tb hdd and come to find out Macs can't write to NTFS hard drives.
What....the....heck, so now I have to wait 10hrs again to reformat my 1TB to FAT32, oh wait fat32 is limited to 2GB files. Great.
Is there a reason why MACs can't right to NTFS drives?

this is how you get native support for Read/write for snow leopard running 64-bit kernal.
After a ton of frustration and jumping through hoops, I thought I'd save a few people out there some headaches.
NTFS-3G + Macfuse does not work in snow leopard 64-bit kernal If anyone got it to work I'd like to know how as I have tried everything an it doesn't work.
So here is an even better alternative.
Remember when Snow leopard was supposed to support NTFS natively out of the box? Well it does...kind of. I'm not sure what happened but Apple was working on it, but in the end decided not to activate it. Kinda almost like the ipod touch with the camera.
Before you can do anything, you must completely uninstall NTFS-3G and Macfuse. Heres on how to uninstall.
Q 2.3. How can I uninstall MacFUSE?
A: Launch the Mac OS X System Preferences application and go to the MacFUSE preference pane. Click on the "Remove MacFUSE" button. This will uninstall all MacFUSE components except the preference pane itself.
You can keep the MacFUSE preference pane around should you decide to install MacFUSE again in the future. If you do wish to remove it, you do it just like how you would remove any other non-Apple preference pane: In System Preferences, control-click (right-click) on the MacFUSE icon and you will see "Remove ..." as an action............

I was curious if Apple has got its fan speed problem fixed for windows yet.
I know alot of people need their fans working good in windows for games and I would hate to have to boot into osx to set fan speed to high just so i could boot to windows to play a game.

I purchased a used macbook pro 2.6 a couple of weeks ago from ebay and it had a screen problem, IMO> anyway I sent it back and got a refund, I just purchased a NEW 2.66 MHz and I'm expecting it at the end of the week, I was impressed how the first mac booted up so fast with OSX so my question is if I had windows XP dual booting would it boot to the windows as fast as it did with the OSX or will the anti-virus slow it down ?

with a native Windows boot... has anyone found a good option for controlling the fan speed?
Right now I have to set a minimum speed in SMCfancontrol and reboot...
The only two options I know of to control fan speeds in Windows is..
Input Remapper: Never worked for me... Vista or Windows 7... it freezes and causes all kinds of problems with the machine no matter what I do.
Lubbo's Fan Control: doesn't work, just gives me and error that it can't load the IO driver. I read that it currently doesn't work right with Bootcamp 3, and to kill bootcamp.exe in order to run it... but that doesn't help either, still the same IO error and it launches and cant detect fans or temps. is there something else out there anyone has tried... or know how to get around the issues with these other two?

My MacBook has been acting weird lately. Its fan speeds just go up to as high as 5k while I'm surfing the web (Firefox), 3k on average. No embedded flash videos, etc. I've searched the net for solutions and none of them work for me. I tried checking my Activity Monitor, and the app that uses the highest CPU % is Firefox at 12% at most. I happened to see Quicksilver go up to 97% for a second then it disappeared. I tried looking for any hidden Print Jobs but I had none. I have 1 stuck process according to Terminal, but that's basically it. I have a 2.4ghz white MacBook, 10.5.6.

I recently updated my MBP with the newest patch and im getting higher cpu temps by just doing my usual web surfing and itunes. I see the cpu raise and my fans will kick on well above 2000 rpm. Before this my computer would normally be stable around 1999-2000 rpm. I can clearly tell by just typing that my mbp is runing hotter.

well last night and this morning i was busy making my self a home made cooling pad, with some crap laying around the house. I don't know if there is already one but i'll put this one up. I will upload pictures tomorrow. The total project was about 1 hour and cost less than $10. It also has a speed control which is cool (it is built on my ac/dc adapter so you will make yours). My mother-tongue is not English but French, so excuse the words i might use or not use. Also their are some tools i couldn't translate the name, but when pics are up I'm sure you will know..................

I've finally got my MacBook Pro 17" specced with Glossy screen, Core i7-620M and GeForce GT330M fully up and running!
I've been replacing the 5400RPM 500GB hard drive with a Intel X25-M 80GB Gen2, along with replaced the 2x 2GB 1066MHz RAM with a pair of nice Kingston 1600MHz @ CL7 2x 2GB ones.
is the fact that Windows7 computer rating tells me that my RAM is the slowest hardware in my machine? So I was checking it's settings, and the MacBook Pro keeps them at 1066MHz @ CL8?
Which is insane considering the potential of these Kingston memory modules!
Is there no way (as there obviously is no BIOS to deal with on Mac hardware) to somehow improve the memory settings?

I've got an Aspire 1652WLMi laptop running Vista Home Premium but seem to have an issue with the DVD drive.
It will read and write CDs fine, it will read normal DVDs fine, it will BURN DVDRs fine. However it wont read DVDRs. Even ones its written (verified working in other PCs) come up as "blank disk" when you insert them into the laptop.
Im not sure if this is an OS problem or a drive problem.

Dell XPS M1710. Phillips SDVD8820 DVD/CD RW Drive. Shows up in hardware manager, but all of a sudden, after writing a few discs in the morning, the drive just stopped being able to either read or write a CD.
I've tried reading both commercial audio CDs as well as audio CDs I've written on the system, and it just behaves as if there is no CD in the drive. Using iTunes, WMP, Media Monkey, and Nero 9...
When I stick a DVD in the drive and let Nero 9 check the drive out, it recognizes what type of drive it is, etc. But if I ask any of those apps to read or play a CD, they all say no CD is in the drive..

I was reformatting my iPod the other day and I left the house to go run some errands and when I got back I was greeted with the BSOD. So I just restarted my computer like always when suddenly I was greeted with this:
PBR 2... done
A disk read error has occurred
Press Ctrl + Alt + Del to restart
So I pressed Ctrl + Alt + Del and got the same message. About 5 times later I was able to run some sort of diagnostics and it was showing something with my HDD. So I tore my computer apart and put everything back in just to see if that would work and I'm still getting the same.
Am I just screwed out of my 20GB of music and all those programs that I had on my computer or is there some sort of fix to be able to recover the data? And will I just have to cave and get a new HDD?

Have you ever had any issues with DVD drive?
I have Optiarc drive (not sure exactly which one but will update later) and problem is that the drive cannot read few DVD/CDs. I have already found 3 such discs : COD5, Fritz10 and one music CD. All discs are original without any scratches.
I have also Acer Extensa and no issues - all discs are read.
