Big HD on LC II with MacOS 7.5?

[silvercreekvalley]

Oops - posted this in the wrong section. Here it is again.

-----

I'm trying to install MacOS 7.5 on a LC II and the disk seems to

be somewhat bigger than the regular Apple disk originally in the

box. Its a Maxtor 7120SR which I think is about 80MB.

When I try to install MacOS 7.5 from the original disks, its unable

to recognise the drive. I know this worked before on a LC II so

I'm guessing there is something I need to do first?

I do have another Mac (Mac Duo) which I could use if necessary

to set the disk up?

Thanks

Ian.

If the drive isn't Apple branded, then you'll either have to use a 3rd party utility or a hacked version of HD SC Setup to format it.

If the drive's capacity is less than a GB, System 7.5 can handle it. There may be other considerations than size. What state is the drive in? Did the drive come from the PC world? What is its recent history? That is:

is it known to be working (even if you are only about to install a same/different System)?

is it recently formatted (with Apple's disk utility, or another)?

is it erased only?

is it terra incognita?

&c., &c.

Do you hear/feel the drive spin up, and do its chk chk chk chrrrk self-test?

The process involves erase (optional), format (obligatory if you have zero-ed the drive completely) and install. If the options exist, is it jumpered for termination, termination power (from itself or from the bus) and SCSI ID. C'mon. 'Fess up. You'll feel so much better ...

Thanks for the replies. Yes the drive is known to be working fine. In fact its formatted. But I cant get beyond the initial install screens as it says drive not supported.

It spins up etc, and I can put it in an external SCSI drive box and see

it OK on another Mac.

I also have an Apple drive, but unfortunately I completely messed this up by - removing the speaker from the LC II to check it (sound had gone flakey) - the magnet in the speaker then attached to the drive (very briefly) after than the drive was completely dead. Hey ho.

It seems the 7.5 installer must have an Apple drive for some reason.

Rather than repeat it, let me refer you to another, related thread. You may have a drive formatted with a non-Apple driver, which Installer will not wish to deal with. You will need to replace the driver (not the formatting) with an Apple driver, or use the option not to update Apple drivers from the Installer, or use the same disk utility to reinstall the driver, and still use the option not to update the (non-Apple) driver from within Installer.

'Non-Apple driver' may include non-Apple formatting. However, in that case, the system is likely to quack that it cannot read the drive at all, and do you wish to erase it (a slipshod expression of inviting you to reformat from PC to Apple format).

Back in 2000 i got given an IBM WDS-80 that i wished to use on my LCII. The thing had never seen a Mac before and was formatted as a DOS volume. Anyway i used Lido to format the drive for use in a Mac, after which i popped a fresh install of 7.5.3 on it. Worked fine.

Lido is a third party app and can format just about any drive, so give it a go. Just when you do the install, make sure that the installer is set to not update the hard drive's drivers. Good luck.

I managed to reformat the drive on a different Mac,

and then install 7.5. Thanks for the help and tips.

Cheers
