Let me save you some time and troubles I had repairing my surplus WorkCentre M24 Xerox copier (Control ROM 4.0.23, Frame ROM 4.134.6).


Problem:
Irregular or slower and slower scanning that finally raises a fatal error.
If tilting the harddisk, while scanning, resolves the issue temporarily, your HDD probably has developed some bad sectors or the disk's spindle bearings have become worn out. In that case or when your disk has crashed otherwise, a new disk is needed.


Solution:
My M24 uses a 20GB Toshiba MK2023GAS IDE PATA laptop disk. Cloning the entire disk using a PC was impossible due to errors on it, so I was stuck.
Attaching an empty disk invokes error 116-330 and running Setup using the PWS (Portable Workstation, check your torrents) didn't work. Unfortunately there is no option to format a new harddisk from the copier's menu panel. So, first of all, I cloned as much as possible from the original disk to the new disk.
AlternativXerox M24 mandatory final sector on disk.zipely you could use the disk image in the attachment of this posting of an original virginally installed HDD that will boot up the machine into the user menu. At least it does so on my machine.

Now the magic trick to solve the persistent 116-330 error: copy the final disk sector (512 bytes) of the original disk (or the attached disk image) to the final sector of the new disk. So if you have e.g. a 60GB MK6034GAX IDE PATA replacement disk you can only get it to work by copying the last sector of the 20GB disk to it. To copy the final sector you can use the freely available HxD disk editor at mh-nexus

If only this single final sector is present on the disk, the Setup from the PWS will pass and you're done.
Without the PWS a new disk may need just enough cloned sectors, or you may use the attached disk image, in addition to the magic final sector to boot up into the menu panel after pressing 4 + Stop + PowerSave buttons to initialize the disk.
Finally, power-up the copier while holding 1 + Stop + PowerSave buttons down to clear the disk log.

The M24 requires a PATA disk of 10GB or bigger. A 60GB disk should be no problem with this trick, nor a PATA SSD. However keep in mind that the M24 was manufactured around 2004 and a disk bigger than 137GB might not work because of this size limit due to an old ATA protocol.

I would have liked to include a complete 20 GB disk image of a virgin disk (just an almost empty 20 MB zip file) to let you boot straight away into the user menu without to resort to a PWS, but the upload manager of this site does not show the upload, although it's smaller than the 45 MB limit .
