1
00:00:00,199 --> 00:00:07,279
the idea of electronics being waterproof isn't exactly new I mean most Flagship

2
00:00:05,319 --> 00:00:12,240
phones whether you're talking your s7s or your iPhone 7S whatever the case may

3
00:00:09,960 --> 00:00:16,160
be they're designed to go bloop into the water yay look at that they survived

4
00:00:13,960 --> 00:00:24,279
it's amazing okay we've all seen this before but what if you could

5
00:00:20,760 --> 00:00:28,199
waterproof a computer hard

6
00:00:24,279 --> 00:00:31,900
drive impractical yes

7
00:00:28,199 --> 00:00:40,559
impossible let's find out

8
00:00:40,559 --> 00:00:46,480
Corsair's 570x midtower case features

9
00:00:43,600 --> 00:00:50,879
four tempered glass panels check it out at the link in the video description so

10
00:00:49,320 --> 00:00:55,559
the first and most obvious problem we need to solve is the exposed PCB that

11
00:00:53,719 --> 00:00:59,039
you'll find on the bottom of pretty much any modern hard drive if you know a

12
00:00:57,640 --> 00:01:05,519
thing or two about water you'll know that while it's starts s non-electrically conductive as soon as

13
00:01:02,879 --> 00:01:11,040
it starts to pick up any impurities or metal ions it quickly becomes conductive

14
00:01:08,640 --> 00:01:15,560
and will cause any electronic devices that are submerged in it for long enough

15
00:01:13,159 --> 00:01:21,360
to short out and or be permanently damaged so I picked myself up a can of

16
00:01:18,360 --> 00:01:25,880
mg chemicals conformal coating number

17
00:01:21,360 --> 00:01:27,520
419c 340g it's xylene free toine free

18
00:01:25,880 --> 00:01:31,840
low vocc if you're into that sort of thing but more importantly it protects

19
00:01:29,920 --> 00:01:37,640
against moisture dirt dust and apparently thermal shocks and insulates

20
00:01:34,799 --> 00:01:45,600
against high voltage arcs shorts and static discharge so Step One is we are

21
00:01:41,240 --> 00:01:47,119
going to treat our PCB with this stuff

22
00:01:45,600 --> 00:01:53,200
okay so let's get started you grab any old hard drive you want and go to town

23
00:01:48,960 --> 00:01:56,439
right wrong so most hard drives today

24
00:01:53,200 --> 00:01:59,119
are actually full of good oldfashioned

25
00:01:56,439 --> 00:02:04,159
air and they've got these breather ports that allow them to stay at the same

26
00:02:01,320 --> 00:02:08,920
internal pressure as the atmosphere around them this is imperative for their

27
00:02:06,880 --> 00:02:14,080
functionality and this is actually the reason why even when you submerge them

28
00:02:11,680 --> 00:02:18,080
in a non-conductive fluid like a mineral oil cooled computer we have a build blog

29
00:02:16,599 --> 00:02:22,200
that you can check out here where we actually explained all of this they

30
00:02:19,800 --> 00:02:26,920
would still cease to work because through these breather ports the mineral

31
00:02:24,200 --> 00:02:32,519
oil or any other fluid would seep in and Gunk up the internals of the hard drive

32
00:02:30,120 --> 00:02:37,879
but there's been a recent development in hard drive technology that leads me to

33
00:02:34,879 --> 00:02:41,159
believe that perhaps we could run a

34
00:02:37,879 --> 00:02:44,200
drive submerged in fluid this is a

35
00:02:41,159 --> 00:02:46,760
Seagate Barracuda Pro it is a helium

36
00:02:44,200 --> 00:02:50,879
filed drive now the point of helium filled drives was more efficient

37
00:02:48,599 --> 00:02:55,360
operation since helium is less dense than air so when you're spinning the

38
00:02:52,560 --> 00:03:00,159
spindles around there's less resistance but it also means they had to seal the

39
00:02:58,200 --> 00:03:04,760
insides of the drives because if the helium got out then you would lose the

40
00:03:01,800 --> 00:03:12,519
benefit right so this is the drive that I will be using 99% isopropyl

41
00:03:09,440 --> 00:03:14,720
alcohol and

42
00:03:12,519 --> 00:03:20,560
bloop don't worry kids this is definitely safe I've done this many

43
00:03:17,040 --> 00:03:22,920
times I'm a professional now let's make

44
00:03:20,560 --> 00:03:28,360
ourselves somewhere to spray cuz I think the spray booth is over in the on the

45
00:03:25,440 --> 00:03:33,519
other side I have to assume this stuff wouldn't be very good to inhale

46
00:03:31,000 --> 00:03:33,519
so don't

47
00:03:37,319 --> 00:03:46,480
breathe okay check this out so I sprayed

48
00:03:40,920 --> 00:03:49,840
the crap out of it like it is pretty

49
00:03:46,480 --> 00:03:51,799
pretty gooped on there and uh it's

50
00:03:49,840 --> 00:03:58,000
actually like built up around the outsides of these chips so what I'm

51
00:03:55,280 --> 00:04:03,200
hoping is we have achieved the water resistance that we need and done so

52
00:04:01,079 --> 00:04:09,959
without damaging the ability of this thing to make contact with the places it

53
00:04:05,439 --> 00:04:14,239
has to so this is where it gets really

54
00:04:09,959 --> 00:04:15,759
sketch well those are all definitely

55
00:04:14,239 --> 00:04:23,199
worn so we're going to reinstall

56
00:04:19,519 --> 00:04:25,520
this on the hard drive and test it

57
00:04:23,199 --> 00:04:30,320
outside before we try to put it in the water

58
00:04:28,360 --> 00:04:35,120
mhm mhm H

59
00:04:32,800 --> 00:04:42,160
mhm so it's possible that the painting that I did on

60
00:04:39,120 --> 00:04:44,440
the PCB covered up these metal contacts

61
00:04:42,160 --> 00:04:49,479
for data and power so we're just going to give it the old have you tried

62
00:04:46,479 --> 00:04:51,479
unplugging it and plugging it back in

63
00:04:49,479 --> 00:04:54,960
repeatedly try and scrape those connectors

64
00:04:52,840 --> 00:04:57,759
clean that does seem to be making a difference I don't know if you can see

65
00:04:56,240 --> 00:05:03,120
that close up there but you can see the conformal coating is uh

66
00:05:01,080 --> 00:05:06,320
coming up I don't even think it's spinning

67
00:05:04,520 --> 00:05:11,800
up H yeah this drive is definitely not

68
00:05:09,560 --> 00:05:17,680
powered up okay so it's a power issue we can work with

69
00:05:13,520 --> 00:05:19,720
that let's get out the old

70
00:05:17,680 --> 00:05:23,520
scraper just go at it a bit more aggressively here can't imagine just

71
00:05:21,600 --> 00:05:29,319
spraying conformal coating on it would have destroyed it found the problem

72
00:05:27,400 --> 00:05:35,720
there were three contact points under here I didn't sand the ones for power

73
00:05:32,880 --> 00:05:41,000
for the motor so of course it's not spinning

74
00:05:37,680 --> 00:05:44,800
up let's go ahead and give that the old

75
00:05:41,000 --> 00:05:44,800
you know hard drive sanding

76
00:05:45,120 --> 00:05:55,280
technique yes okay there it is there's our 10 tbte

77
00:05:51,680 --> 00:05:58,600
Drive okay

78
00:05:55,280 --> 00:05:58,600
so it's

79
00:05:58,639 --> 00:06:08,880
time time for what time to figure out um

80
00:06:04,560 --> 00:06:12,000
what data I can copy for a test I am

81
00:06:08,880 --> 00:06:16,280
basically going to take the drive and

82
00:06:12,000 --> 00:06:16,280
put it in we're going to see what

83
00:06:17,240 --> 00:06:24,360
happens what the hell is this okay so

84
00:06:21,440 --> 00:06:30,160
it's some kind of land issue I will deal with that later in the

85
00:06:26,520 --> 00:06:32,039
meantime I've got a USB type-c

86
00:06:30,160 --> 00:06:38,599
Ethernet adapter here and I've have started three

87
00:06:33,639 --> 00:06:39,960
transfers each of like 2.3 terabytes

88
00:06:38,599 --> 00:06:47,160
worth of data so you can see here we are

89
00:06:43,599 --> 00:06:49,319
transferring to the adventure drive from

90
00:06:47,160 --> 00:06:56,319
the network so this should take quite some time now this is where it gets real

91
00:06:52,280 --> 00:06:56,319
so I'm going to take this

92
00:06:57,639 --> 00:07:05,759
drive which is currently right data and ever so

93
00:07:02,960 --> 00:07:12,400
carefully cautiously and not at all

94
00:07:08,160 --> 00:07:16,280
recklessly oh this pains

95
00:07:12,400 --> 00:07:18,240
me I'm actually in pain right

96
00:07:16,280 --> 00:07:24,160
now okay I am liquid

97
00:07:20,720 --> 00:07:24,160
cooling the hard

98
00:07:27,599 --> 00:07:31,520
drive okay I'm halfway in

99
00:07:32,680 --> 00:07:40,199
in about 3/4 of the way

100
00:07:36,720 --> 00:07:40,199
in is it still

101
00:07:45,800 --> 00:07:53,599
transferring still going let's go get some more

102
00:07:50,000 --> 00:07:56,080
water okay so to absolutely

103
00:07:53,599 --> 00:08:02,039
prove that there's no smoke in mirrors that's not mineral

104
00:07:57,919 --> 00:08:04,319
oil here's a new ug look tap water tap

105
00:08:02,039 --> 00:08:04,319
water

106
00:08:09,680 --> 00:08:15,240
AF let's top it up still

107
00:08:13,440 --> 00:08:24,440
transferring but don't take the camera off me we're proving this is a continuous shot here we go okay tap

108
00:08:20,000 --> 00:08:24,440
water AF there goes the power

109
00:08:24,879 --> 00:08:31,560
connector and the drive is submerged

110
00:08:29,560 --> 00:08:34,560
still transfering

111
00:08:42,000 --> 00:08:49,480
no okay so let's get the moisture I think the power shorted I think that's

112
00:08:47,000 --> 00:08:53,839
what happened here uhoh I don't know what effect alcohol has on the conformal

113
00:08:52,080 --> 00:09:00,560
cating um did not think that

114
00:08:57,399 --> 00:09:02,920
through okay so it's been Popp in kind

115
00:09:00,560 --> 00:09:08,200
of in and out of being detected um I think it's to do with the

116
00:09:05,160 --> 00:09:10,560
power connector but quite honestly see

117
00:09:08,200 --> 00:09:13,760
here if we try again now boom it's transferring get now it's gone I don't

118
00:09:12,120 --> 00:09:18,120
know what we were trying to prove anyway putting it in water because it has no

119
00:09:16,720 --> 00:09:22,160
real practical application so let's just go get some

120
00:09:20,000 --> 00:09:26,279
mineral oil so I found all the mineral oil from

121
00:09:24,800 --> 00:09:30,720
the mineral oil PC I sincerely hope that I'm not going

122
00:09:29,519 --> 00:09:34,240
to make a mess here but as you guys know I'm allergic

123
00:09:33,040 --> 00:09:42,320
to funnels so uh the Chan is seem pretty

124
00:09:38,079 --> 00:09:42,320
good here we go

125
00:09:42,880 --> 00:09:50,399
sh wonderful now

126
00:09:47,600 --> 00:09:56,440
okay so here we go can it handle mineral oil I want to

127
00:09:53,839 --> 00:10:02,800
see a longer sustained transfer here kids that's what I want to see so you

128
00:09:59,800 --> 00:10:05,800
saw it here first

129
00:10:02,800 --> 00:10:08,240
folks liquid cooled hard

130
00:10:05,800 --> 00:10:12,120
drive hopefully my editors have found some way to turn what's happened in the

131
00:10:10,399 --> 00:10:17,839
last half an hour or so into some kind of coherent narrative and hopefully you

132
00:10:15,519 --> 00:10:21,000
guys enjoyed it if you aren't familiar with mass drop they're the community

133
00:10:19,399 --> 00:10:24,920
where users discuss products that they're interested in buying and then

134
00:10:22,760 --> 00:10:29,279
Mast drop talks to the manufacturer and negotiates a bulk order at a discounted

135
00:10:27,560 --> 00:10:35,360
price and they're Now featuring featuring a drop for the high-fi man re

136
00:10:32,360 --> 00:10:37,440
IM they have 9mm Dynamic drivers and

137
00:10:35,360 --> 00:10:41,959
they ship with two pairs of silicone ear tips and they're only about $35 which is

138
00:10:40,320 --> 00:10:46,639
pretty sweet so check them out and other drops at the link in the video description down below thanks for
