Hi Guys,

Hope someone can sell me one of these. :-) Dunno which numbers matter, but here goes. I live in USA, by the way. The drive was working great, but now just makes a clicking sound and occasionally a sound that resembles the blooping sound of dropping a small stone in water, but more machine-like and metallic sounding...very difficult to describe...it's kind of like when you spin a small coin like a top and when it is a fraction of a second from stopping...yeah, that kind of sound, hah hah. I have an identical drive that's been running for years, but it is my primary drive and I really don't want to remove the PCB from it.

Drive:
Seagate ST3300622A 300GB 7200.9
PN- 9BD044-304
Firmware Version 3.AAH
Site Code WU

PCB:
Numbers on IDE connector:
64I1
100327114

Numbers on largest chip:
100404195
SEAGATE
PTKNCB2-E16
0614K
4075407
4075407001
100367049

Numbers on small bar code on PCB:
100373052 K 3645YHAX

Numbers on smaller chip:
SMOOTH
100369972
9911H VP
MYS 99 613

Thanks very much, everyone!

-Rob

I apologize for the quality of the photos. It seems my camera does not capture detail very well close up.

I hope this is helpful enough! If needed I could borrow someone's scanner for more detailed pics.

Thanks again!

Almost certainly head problem rather than PCB, from the description of the sound.

Yes, now that you mention it, it definitely sounds like the preamp might have gone, as it was running hard for a couple days in a row before it began making that sound. I take it an identical drive is needed to find a new head for it? Or is there another way to find the correct model head? Thanks!

Yes, not only do you need to find matching parts, but also clean room, tools, skill and experience. You will almost certainly also require an imaging tool once the heads are swapped and there will probably be some media damage. Oh, and possibly a firmware repair tool.

Its not like changing batteries in a remote control.

If you've never done it before, then don't. I ruined many drives in practice (NOT live client drives, I hasten to add!!!)

Sorry to say, but this is a PRO job.

Yes I understand, PCimage. Luckily, the data on the drive is not particularly important, and certainly not enough to warrant pro recovery. I don't have access to PC3000, nor the $250 or so for a platter swap tool. The clean room is the easy part. Also, the drive is under warranty, so I may go that route instead. This is why I figured I may try a PCB swap just for the heck of it...if it didn't work, I'd just return it to Seagate.

Yep, RMA it.

Thanks, guys. Yeah, I just RMA'd it. BTW, are networks of folks like yourself and eBay the only good places to buy single units of PCBs? Sorry, if that's like a trade secret or something, it's just that I spent way too much time looking for this one before I just gave up and RMA'd it.

Thanks again!
