Re: Are powermac g4 still useful?
-- Original message -- Subject: Re: Are powermac g4 still useful? Date:Tuesday, 03. January 2012 From:Valter Prahlad valter.prah...@fastwebnet.it To: g3-5-list@googlegroups.com I can't understand your concern. Am I missing something? Number of download seems increasing to me. Considering only the RC/final 4 versions (G3, G4x2, G5): TFF 4.0.1 = 19904 TFF 7.0 = 20703 TFF 8.0 = 22334 I for one downloaded TenFourFox in *all* its optimized builds, because I do have a G3, G4s (both kinds: 7400 and 7450) and G5s. So, 1) technically you should only count me once. And 2) I am sure that some people downloaded it twice. I’d estimate no more than 10,000 TenFourFox users, which is then in return a good estimate of users still running PowerPC-based Macs. On the other side there are some million Firefox users. Don’t get me wrong. I’d say that 10,000 is enough to keep the developement going, and I’m very very grateful and happy that Cameron Kaiser and Floodgap Systems is doing all the work. I love the idea of having an AltiVec-optimized WebM engine on my PowerMac, and the faster JavaScript interpreter, which makes me wonder where it has been all these years before TenFourFox! I didn't consider TFF 9, because it's still work in progress. DL numbers seem going up, though. Version 9.0 is current, you should update immediately as it closes a few security holes and fixes some bugs.

Re: iMac G5 won't power on
bruce--i should have thanked you for the link. i found my way to badcaps.net, a very interesting site. i removed the power supply, and tested the outputs. i got 11.56v on both 12v outputs. that leads me to believe the problem is with the caps on the logic board, which there is a kit for on the above site. i'm considering whether my soldering skills are up to the task. btw, the person that gave me this kept the HD, but also kept the temperature sensor that is glued to it. will the computer boot without the temp sensor plugged in? if it won't i will try to find a pinout for that connector and make a jumper. thanks ken On Jan 2, 7:41 pm, Bruce Johnson john...@pharmacy.arizona.edu wrote: On Jan 2, 2012, at 4:03 PM, faithie999 wrote: which are the power supply caps on the logic board? there are probably 20+ caps in all on the board.

Re: External hard drive vs. online back up sites
Vembu StoreGrid supports MAC OS. You can install StoreGrid client in your MAC OS machine and take the backup to online servers, which may be (WINDOWS,Linux). Vembu StoreGrid supports client install for the following MAC OS versions, 1. Mac OS X 10.3.x (Panther) and 10.4.x (Tiger) for PowerPcs 2. Mac OS X 10.5.x(Leopard), 10.6.x (Snow Leopard) and 10.7 (Lion) for Intel PCs You can try the Vembu StoreGrid clients in MAC OS with the online servers (WINDOWS, Linux).

So it provides data saftey while transfer through network. Also it supports incremental backups, during the incremental backup only modified bytes will be transferred, so we no need to worry about the amount of data upload. It check the integrity of the data once the backup completed successfully. Too slow for large drives. Yes of course. To overcome this slow transfer, Vembu StoreGrid supports seed backup migration feature to avoid the data transfer through network. i.e, You can backup your drive in the local location, once backup completed in the local drive then you can copy the data and seed it in online server without any data transfer via network. Once you seed the data in the online server, thereafter only modified data will be transferred during the incremental backup.

Check for crash logs. Check your system.log for error messages pertaining to that particular volume. I can see the drive in Disk Utility and System Profiler. Disk Utility says it is fine when I repair it. I'm guessing you mean that those tools can see the ***volume*** (partition), and not just the whole drive itself? And that you've repaired the volume? This is telling: That the other volumes (partitions) are working means the disk itself is working well. That Fsck, the actual Unix tool for which Disk Utility is a basically a GUI, is happy with the borked volume means that that volume's file system data structures are probably ok. But then Finder and apps die when you actually try to access the volume... try to access a specific directory (even if it's just the top level root)... means that there is a corrupted directory or index therein. IOW, the filing cabinet is fine. The drawers in the filing cabinet are fine. The problem, most likely, is that one of the hanging folders, in that one drawer, has exploded. Hopefully it did so without destroying the files therein. First, try turning Spotlight's indexing off on that volume. If that doesn't help, then try mounting the volume read-only and see if you can make a complete backup, then dismount the volume, erase it, and reload it. Turn off Spotlight's indexing with this command: sudo mdutil -i off /Volumes/fooVolume Replace fooVolume with the name of your disk volume. If the name includes any special characters then enclose the whole name in doublequotes (eg: my Stuff). Not that the command is case sensitive.

Re: Firewire HD Partition is not accessible. Very strange.
This is telling: That the other volumes (partitions) are working means the disk itself is working well. That Fsck, the actual Unix tool for which Disk Utility is a basically a GUI, is happy with the borked volume means that that volume's file system data structures are probably ok. But then Finder and apps die when you actually try to access the volume... try to access a specific directory (even if it's just the top level root)... means that there is a corrupted directory or index therein. IOW, the filing cabinet is fine. The drawers in the filing cabinet are fine. The problem, most likely, is that one of the hanging folders, in that one drawer, has exploded. Hopefully it did so without destroying the files therein. Applejack won't help with an external drive and it and Disk Warrior do different things. DW fixes corrupted volume directories. That's all it does, but it does that one thing very well. In the future please put the hardware and OS informations at the TOP of the message. Ok, thanks everyone for all your help. So far I have determined that it is most likely a bad partition. I thought about Applejack but then called OWC and they say that I should be trying Data Rescue or Disk Warrior. They say that the drive is probably ok but that volume/ partition is hosed as far as the file directory is concerned. I'm hoping my data is recoverable. I did try to connect via USB2 but the drive doesn't even spin up. It is a 7200 rpm drive and OWC says it is being under powered by the USB bus upon turning on the drive as it needs more power to spin up. Sounds like BS to me as my 5400 rpm OWC drive does the same thing and does not mount via USB. OWC recommends a power adapterBut that is not my main concern right now. I think both Dan and Bruce are right with respect to what is going on. Dan I like the analogies/euphemisms. Just to note also that in Disk Utility I did repair the entire drive and all individual volumes and they all reported as ok. I'm going to try and repair the drive with DW or DR and hope my stuff comes back. First I'll check the system log and see if there is anything else in there of note and also try terminal. I'll attempt the read-only mount and see if that helps too. I did try to turn off spotlight indexing on that partition but once I click on that volume system prefs just closes/crashes. I'll try it via terminal as described. I will state my machine specs first next time although I do like using GOTO commands...

Advice for too many FW devices...Got Hubs?
RE: 17 G4 1.5Ghz Powerbook (2006) and an Intel Mac Mini 2.4 Ghz (2010) both with maxed out RAM and most current OS.

Seee: http://www.1394ta.org/consumers/FAQ.html#FW800DaisyChain It scares me personally. It shouldn't, it's a standard feature of the firewire standard. Remember, FW was adopted as a replacement for SCSI, and one of the design goals was decent daisy-chaining performance.

I've replaced caps on dozens of iMac G5 and eMac G4 logic boards, and in a dozen or so iMac G5 power supplies. I started out replacing all of them, but I've come around to where I now replace only those with bulging tops or with bulging/leaking tops or that are tilted noticeably because the bottom rubber plug has blown (rare). My success rate of revival has increased dramatically since I started replacing only the observable bad ones. This is most likely due to the fact that it's extremely difficult to remove and replace caps on iMac G5s without damaging the internal traces in the layers of the logic boards, or failing to adequately melt the high-temp solder used by Apple and thus effect a good solder bond. Even after I've succeeded in reviving some iMac G5s, I have to go back and resolder a few joints that have come loose after a number of heat up/cool down cycles. If you're a glutton for punishment, go for the recaps. But be prepared to never completely trust that iMac again. On the other hand, I've have no failures of any eMacs whose capacitors I've replaced.

On Jan 3, 2012, at 6:43 PM, faithie999 wrote: None of the caps are visibly damaged, but I know that doesn't mean that one or more aren't faulty. Well, I don't know about that. At first, I bought the idea that a capacitor could be bad even if it didn't exhibit any signs of failure, i.e. leaking, bulging, tilting. But then I got to thinking about what caused the problem of bad caps for almost all of the world's electronics manufacturers who used caps from the manufacturer who stole the electrolyte recipe. The stolen recipe was missing a key ingredient: the stabilizer that prevented the electrolyte from boiling/overheating, which then caused the caps to become unstable and not be able to hold their voltage values. The worst caps even exploded, and I've seen a number of those. Just found one inside a 1 GHz Sept. 2004 eMac tonight, in fact. I also realized that the strongest recommendations to replace all caps irregardless of their visual condition came from people who were in the business of selling capacitor kits and soldering supplies. That's when I started replacing only those caps that looked bad, and suddenly my success rate climbed sharply upward. Of course, instead of replacing up to 27 caps on a board, I was replacing a half-dozen or so. That alone limited any damage -- hidden or not -- that might be done by removing caps unnecessarily. I've revisited a number of boards that have had only bad caps replaced in the last couple of years, and no more bad caps have appeared. So I've concluded that if one of the stolen-electrolyte-caps was going to go bad, it already has done so in the last 7 years or so. That doesn't mean the remaining stolen-recipe caps won't go bad in the future. Look at all the G5 iMacs that worked fine during and even after the official Apple bad-cap replacement program, then failed. But I suspect any original 2004-2005 or so stolen-recipe cap that's still in use would have failed by now if it were going to do so. Still, the main difficulty in replacing caps as a hobbyist -- advanced or otherwise -- is the lack of a proper professional-grade solder work station. It is godawful hard -- impossible I wager -- to get the no-lead high-temp solder Apple used in G5 iMacs to melt adequately during cap removal and replacement using consumer-grade soldering equipment. This causes iffy solder joints inside the holes, even if the solder adheres to the pads on the surface.
