Need Help Trouble Shooting K100D Computer (?) Problem

Dear Listmembers,

I have a Pentax K100D with A Pentax 18-55, Pentax-F SMC
100 mm Macro, and another stadard lens that use with it.

I quite frequently use to take pictures for work and frequently
download these pictures to my Macintosh computer. the details
of my Mac computer are:

Machine Name: Power Mac G5 Quad
Machine Model: PowerMac11,2
CPU Type: PowerPC G5 (1.1)
Number Of CPUs: 4
CPU Speed: 2.5 GHz
L2 Cache (per CPU): 1 MB
Memory: 4 GB
Bus Speed: 1.25 GHz
Boot ROM Version: 5.2.7f1

About four days ago my computer crashed when a hard drive
that I used for backing up data died. When I got my computer
working again, I find that my work computer does not recognize
the memory in my camera when the camera is plugged in and
turned on. In addition, when turn on my camera independently
of (unattached to) the computer and without the UBS cord
attached, the carmera still indicates that it is in PC mode.

What is wrong with my K100D and what, if anything can be
done about it?

Best Regards,

I don't have a Mac but when that happens to a PC, as in you kinda like restart over, you have to make sure that you have uploaded all the drivers of the computer as originally before it crashed.
You might have missed a driver (usb divers, maybe?) so that the computer will recognize the input (camera or attached usb cord with removable drive).

Hope the camera is under warranty, that PC mode showing suggests the output port is malfuntioning and is in need of repair. You could also try using a friend's laptop card reader, most read the SD cards these days to see if the card isn't the problem and making the PC message show when no data transfer lead is attached.
Fact is I really don't know and just suggesting what I'd consider basic trouble shooting.

Try to find out if it's the computer or the camera. IE: try the camera on another computer, and try something else on the USB-port.

If the camera shows PC mode even without a USB cable plugged in, I would remove the batteries for a minute or two & reinsert. It's possible that an unclean disconnect when the computer crashed confused the camera. If that doesn't work, it sounds like the camera's USB port is fried.
