The hard drive on one of my H120s died so I needed to buy a new one. I did some digging around and checked out the suppliers in NPSwimdude500's FAQ. I also decided to check out eBay and found this supplier:
lejclip
I saw he was selling a MK3006GAL (30GB Toshiba 1.8" hard drive) and bought it for £70 including the shipping to New Zealand. That might seem a
little pricey to U.S. or possibly even U.K. buyers, but not when you consider that the shipping costs of such items from overseas to New Zealand is the killer. I checked out the cost of this drive on
Span (U.K.) and it's £81 on top of which I no doubt would have had to pay a fair amount in shipping. Also, this drive seems to have been on backorder on Span's website for ages. The other reason I thought the price was pretty good was that another
used MK3006GAL went for the same price on eBay last week.
The drive arrived in 3 days (which I thought was awesome) shipped from Hong Kong to New Zealand. I installed the drive in my H120 and it works perfectly. I'm very happy because instead of a broken H120, I now have a fully functional H130!
I contacted the seller and asked if he can get more than just the hard drives that he currently has in his listings. He said that he regularly deals in these hard drives. I'm sure that if he doesn't currently have any of the Toshiba drives listed, then he wouldn't mind anyone contacting him to see if he can source one. His name is Matthew and his email address is:
lejclip (at) yahoo (dot) com (dot) hk
Before anyone thinks that I'm on a commission here, let me assure you that I'm not!

I decided to post this information as I have seen the question about where to source compatible drives being asked quite a few times on different threads. I thought that listing another potential supplier of replacement hard drives would be useful. Also, I appreciate that this is just one person's experience - other peoples' mileage may vary. But the guy's feedback is almost 100% positive, so that tells it's own story.
If any of the mods think that it would be appropriate to include this information in other threads/forums for greater visibility then be my guest.
