Re in circuit ESR meter:
If you have a breadboard and an hour, this does pretty much the same
thing with £10 worth of parts, less if you have a junk box:

If those pins are all inputs, then you don't need to rewire anything.

Well. I took up one of the capacitors and the label says the following:
HCGFA

SURGE 500 VDC

Here is an ebay link that shows the actual capacitor that I have.

Around 2TB there's YET ANOTHER ONE stupid software disk size limitation
that maybe prevents your BIOS/motherboard combination from seeing your new
drive. It may or may not use 4192 byte sectors: Toshiba website is really

I would not bother buying used caps. (Not sure you were)
Power electrolytics have a rated life listed in hours and you would be
amazed at how few hours some caps are rated.
I would only buy new caps or NOS (New old stock) caps.
