Card Reader Issue

[nekrosoft13]

i swear i don't have good luck with card readers, first i had external usb card reader, which stopped working about 2-3 weeks after i bought it.

now i have this internal reader

it was working fine for about 1 week, now when pc boots, in post it shows green and red led. once windows starts booting (windows logo) red led goes out, green one blinks 2-3 times. once in windows it works fine for a while. then the green led goes out, all 4 remove drives still show up in my computer, but when i insert a card, nothing happens.

seems like its their but, no one is home

I noticed with my internal card writer/reader, sometimes I have to take out the usb wire and then re-insert it and its all good, I think in my case, that long term vibration makes the wire slightly come loose thus affecting connectivity, could be the same case with you ?

hmm i have coolermaster stacker 830, i don't think it "vibrates"

when the reader stops working, the LED turns off, but the device is still present in Device Manager, Removable disk show up under My computer, when i insert either SD or CF card, nothing happens, when i double click the remove disk, it opens up, but its blank no data.

weird thing is if i use the drive constantly, it will work, when i stop using it for 10 minutes, LED turns off

I looked in Device manager, but there is no mention of power saving anywhere

alright it seems to be somehow connected to my external drive

card reader is based on alcor chip, external drive is based on cypress

once i turn on the external drive, about 5-10 minutes later card reader dies

so now the question is, should i replace the card reader, or the external drive :|
