grannysmith Posted February 27, 2007 Share Posted February 27, 2007 (edited) Hi friends: I'm totally new to this, though have a little Linux experience and I'm a Windows/hardware technician by day. I've read some of the HCLs, and some of the install HOWTOs. I've been trying to get JaS 10.4.8 revised version installed on my system. Single boot from one IDE drive. No dual or triple anything here-I wouldn't dare. I don't even want OS X to recognize my SATA drive-it'll keep trouble to a minimum. I keep getting the same error, whether in verbose mode or not: creating RAM disk for /var/run . . . disk1: I/O Error disk1: I/O Error localhost diskarbitrationd[33] unable to mount /dev/disk01s (status code) 0x00000047) /private/var/temp: optimization changed from TIME to SPACE Confid[31] No AirPort Driver Found Confid[31] Error copyAirPortScPrefsRef can't commit prefs: no such key Equipment includes: Abit KN8-SLI (I've read this works just fine with 10.4.6) 1 GB GeIL DDR-400 RAM Maxtor 6Y160P0 160GB Hard drive (IDE) NEC ND-3520a DVDRW (IDE) BFG Nvidia 6600 PCI-e video card Logitech USB Cordless Trackman Keytronics PS/2 keyboard (Tried a USB model - it didn't help) I disconnected the other (Windows) SATA drive in my machine, but I'm wondering whether disabling SATA in the BIOS or setting SATA to emulate PATA would help in my situation, as it did in this thread. Unable to mount disk If not, does it make a difference with what filesystem the target drive is formatted? In some places, I've read it must be FAT or FAT32, but not NTFS. In other places, I've read it doesn't matter-Disk Utility will be able to wipe it. In still other places, I've read HOWTOs that recommend that you repartition the drive with one large partition only and not format it. Currently, the one and only partition is not formatted. I used diskparted to partition it to max. size. I would've just tried a few of these things, but it seems to take about 1/2 to 3/4 of an hour of time for the booting process to just get to this point each time. So I'm asking for help. Oh, and BTW, does the installer write a logfile anywhere of its progress by default? If not, can one get it to do that? Thanks in advance for any suggestions grannysmith Edited February 27, 2007 by grannysmith Link to comment https://www.insanelymac.com/forum/topic/43694-unable-to-mount-devdisk01s-error-on-jas-1048/ Share on other sites More sharing options...
hecker Posted February 27, 2007 Share Posted February 27, 2007 So you have one IDE drive and one DVD-Drive connected, right? Are they connected together? If so, Is the HDD drive set as master and connected in the middle? As a side note I have read that you need to use a mouse and keyboard with the same connection type. No mixing USB and PS/2. hecker Link to comment https://www.insanelymac.com/forum/topic/43694-unable-to-mount-devdisk01s-error-on-jas-1048/#findComment-312500 Share on other sites More sharing options...
grannysmith Posted February 27, 2007 Author Share Posted February 27, 2007 Check, hard drive was set as master, DVDRW as slave. As I said, I had the SATA HDD disconnected, but didn't disable SATA in the BIOS. I did try it a second time with a USB keyboard, but maybe I'll try it again. Do you have any reason why you are convinced that a disk I/O error could have been caused by using a PS/2 keyboard? The two seem like awfully separate systems... Thanks for your suggestions.

hecker Posted February 27, 2007 Share Posted February 27, 2007 (edited) I'm sorry, I should have elaborated I just wanted to point out that having PS/2 and USB mixed causes problems with OSX. But I didn't mean it had anything to do with your current problem. Back to the problem: I had the "disk I/O" problem once with my drives were not configured manually in the BIOS or when the DVD was set to master. OSX would even recognize devices that were set to "disabled" in the BIOS. I fixed the problem by setting everything I could manually. Speeds, access methods, everything. There seems to be some issues with SATA at this time and that's why I would recommend disabling SATA completely from the BIOS and unplugging all unnecessary devices as well. It's just a way of narrowing things down. You can always add stuff later. Have you tried booting in safe or single mode? -s for single user mode and -x for safe mode. Also keep using -v for verbose mode. I am not aware of any installation log files but every other files are stored in /Library/logs hecker Edited February 27, 2007 by hecker Link to comment https://www.insanelymac.com/forum/topic/43694-unable-to-mount-devdisk01s-error-on-jas-1048/#findComment-312654 Share on other sites More sharing options...
grannysmith Posted February 28, 2007 Author Share Posted February 28, 2007 (edited) Okay, replaced keyboard with a USB one, and disabled SATA in the BIOS. The installation proceeded, SLOWLY. I didn't know that at times there would be no disk activity or any indication of any activity at all for 15 or 20 minutes at a time. Oh, and I made the mistake of choosing to zero out the disk, which took 3 hours. It took about 6 hours of total install time to finish the installation. After trying to boot the system post-install, the system only gets to just past the POST screen to the device enumeration screen listing the hardware components, and then hangs. No error message, nothing. What's more, as long as that hard drive is connected, it will prevent any other drive from booting-even from a CD. I just don't get it. This is very frustrating. Does anyone have any suggestions?

grannysmith Posted March 1, 2007 Author Share Posted March 1, 2007 (edited) UPDATE: I tried connecting the Maxtor IDE drive to another PC. That PC booted without any problems, (from the Windows disk, of course) and recognized the disk and the volume type in Disk Administrator as: "CPT Protected partition" or something similar. Can't remember what the three letter acronym was. That rules out that the drive is bad. Can anyone fathom what would make this drive prevent a KN8-SLI - based machine from booting? BIOS bug? Can anyone at least tell me what "CPT protected partition" (or whatever that acronym was) means? grannysmith Edited March 1, 2007 by grannysmith Link to comment https://www.insanelymac.com/forum/topic/43694-unable-to-mount-devdisk01s-error-on-jas-1048/#findComment-314274 Share on other sites More sharing options...
hecker Posted March 1, 2007 Share Posted March 1, 2007 Don't you think it would be easier if you would actually knew what the acronym was?

grannysmith Posted March 2, 2007 Author Share Posted March 2, 2007 (edited) Hecker: Thanks for your help. Okay, I finally had time to look at that IDE drive again in the other machine. Disk Admin. describes it as having a "GPT [GUID] protective partition". Apparently, this is a different partition type than the standard MBR record. Even Microsoft is now using the standard for some of their newer OSes. Microsoft on GPT Protective Partitions. Even so, if I understand those docs correctly, 32-bit versions of Windows should still have no trouble recognizing the protected MBR of those partitions. Well, when I looked at the disk in Disk Admin., I could see the partition, but I couldn't format it. Whoah! Okay. It would have been nice to see some warning about this in the "fruit-flavoured" OS install guides that I read. So it turns out that so-called "old-fashioned" partition utilities cannot format a GPT protective partition. According to this post, there are two common ways to reformat a GPT protective partition: Formatting a GPT Protective partition All that being the case, I still don't understand why having installed that "fruit-flavoured" OS, even if it created a GPT, would prevent the POST test from completing on any machine. I would like to try reinstalling that OS when I have time, but not if it causes these problems again. Anyone know how to avoid this? Anyone?
