hello,

I was formatting my drive and found under - diskutil list - in Terminal,
that I had 4 other disks that I was not aware of.

When I go back in disk utility, I have only
1 - 55.9GB ATA disk
1 - mounted volume (disk)- that is not partitionned (I don't have access to partition controls)

But when I get info of the disk, partition number is 3??

I have erased 3 times the disk - OS extended with 7 pass erase
And the 4 other disks still show in Terminal

Tried diskutil mergePartitions but won't work - these are no partitions but seperate disks...

I would like to restore my disk, remooving all these other disks (partitions?)

*Mac OS9 drivers option is not available when I try erasing the entire disk...

Need help

thank you

All drives, when formatted, have partition map, drivers and index partitions. You cannot rid yourself of those and still have a formatted disk. Some utilities can erase all those, but then the drive will be unmounted and unmountable until you format it and add them back in.

Same same for a windows drive.

thank you Rick

So when I have the installer disk in and the drive is completely empty, wainting for OSX, it's normal to have in diskutil
/dev/disk2 untitled 467.0 Ki
/dev/disk3 untitled 467.0 Ki
/dev/disk4 untitled 95.0 Ki
/dev/disk5 untitled 95.0 Ki ?

These "disks" are actually drivers and index partitions?

thank you

That appears like you have 4 drives of one sort or another. Here's one external drive and one DVD mounted on my computer as shown by listing DiskUtil:

/dev/disk3
#:     TYPE NAME     SIZE      IDENTIFIER
0:    Apple_partition_scheme    *465.8 Gi disk3
1:    Apple_partition_map    31.5 Ki     disk3s1
2:     Apple_HFS TimeMachine     465.6 Gi    disk3s3
/dev/disk4
#:     TYPE NAME      SIZE      IDENTIFIER
0:   Apple_partition_scheme   *4.4 Gi   disk4
1:   Apple_partition_map     31.5 Ki    disk4s1
2:     Apple_HFS First to Fight     4.4 Gi    disk4s2





The /dev/diskx each are different physical drives whether DVD, USB, FW, SATA or anything else mountable. You can have several named partitions on a given drive as well.

Could the 4 additional disks be RAM-Disks used for temporary files?
I had OSX installer CD in when I used diskutil...

Format and name your drive, see if it makes a difference. At least that way you get to see which is that drive.

I printed out the simple volumes on the last list, here's a screenshot of my boot drive and my user drive. The bottom 2 lines are the mounted volumes: 'Root" , "Backup" , "Local.old" , "RootTwo"

Hello Rick
I checked it out.
The 4 disks are disks images when I have the installation dvd in.
Onces installed, the disks disapear.
I still reformated the disk, wanted to know for os9 drivers.

why os9 drivers checkbox are still not showing in installation with diskutility.
I read that if this option is not there, it's because the disk is still partitionned.
I've repartionned, mergerd partition, did 1 partition, and still, no option.

My question:
Does OS10.5 still support OS9 drivers?
Thank you

sorry for the delay
