Hi,

This afternoon I was able to use my hackintosh without any problems. I shut down the computer, went out and now I returned home and it was hanging on the boot up screen.

After booting in verbose mode, this is the error I get

 

USBF: 6.519 AppleUSBEHCI[0x4ddd800]::Found a transaction which hasn't moved in 5 seconds on bus 0xb3, timing out! (Addr:2, EP:0)
continuing
done
syncing disks... killing all processes CPU halted: It's now safe to turn off your computer
USBF: 13.519 AppleUSBEHCI[0x4ddd800]::Found a transaction which hasn't moved in 5 seconds on bus 0xb3, timing out! (Addr:2, EP:0)

 

Also, when I try to access the disk in Vista, I get this error

 

E:\ Is not accessible
The Disk Structure is corrupted and unreadable

 

 

I haven't done anything really, just using Firefox and Adium.

 

I'll post my system specs now.

Processor - DualCore Intel Core 2 Duo E4600, 2400 MHz (12 x 200)
Motherboard - Acer MRS600M(3 PCI, 1 PCI-E x16, 2 DDR2 DIMM, Audio, Video, Gigabit LAN)
Chipset - ATI RS600
Graphic card - ATI HD 2400 PRO (256 MB)

 

I really hope I haven't screwed this disk partition. I had so much in it...

Thanks for all the help that might come.

This problem is caused by the failure of USB disk writing under OSX. The MBR of the disk is erased, but the partitions are intactly preserved. So, to fix this you might need some knowledge of the MBR structure of the disk. Any mistake will destroy your data in your disk. I fixed one time before, first you need to know how many partitions you have in your disk and the order of your partitions.

 

Second, goto XP or vista, find a programe that can edit the raw disk (I used Winhex to edit the disk, it is very dangerous, if you choose the wrong one, you might screw up both of your disks).

 

Third, find a program that is able to find/recover NTFS partition to search the disk for you and help to find out the start sector of the NTFS and it size. No program can find the HFS+ partition for you. If your HFS+ is the first partition, it would probably starts at the 0x3f(63th) sector. Or, if your HFS+ partition is after NTFS partition, you can try to see the sectors after you NTFS partition to find the start sector of the HFS+ partition.

 

The start sector of HFS+ partition contains the text of "HFS" and after the start sector there some sectors contain a lot of FF FF FF FF FF ... .

 

Fourth, caluates the start sectors of you NTFS and HFS+ partitions and they "LENGTH", then use winhex to re-build the MBR and save (You should know what you're doing, the action is definitely dangerous and might kill your data). Now, you can reboot to see if the saved MBR is working or not.
