    Western Digital 1600PB

    thanx for the info seb. if and when i buy one of these things, i shall let you know my opinions. to be honest, i watercool my hard disks; this i do in order for me to run the hard disks wrapped in denim. this in turn, quietens the hard disks to such a point where i can no longer hear them at all. this works on very loud hard disks. so really, noise isnt really an issue here. however, i was thinking of perhaps buying a hard disk and a removable hard disk rack, in which case, i will need a quiet hard disk.
  2. ive just seen this drive. does anyone know what the PB suffix means?

    i think ive answered my own question. the PB suffix means fluid bearings, so quieter operation. but i wonder how reliable these are compared to the normal JB drives. has anyone got a PB drive, if so are they really quieter?

    sorry, the url isnt working in the desired way. click the given url, then search for item 121356. what does PB mean? thanx
  5. well i not only have mp3s, which in all honesty dont take up much space (1.33gb), but i also record music videos from dvds and from my digital tv card (currently 7.17gb). i have also archived a few of my dvd movies onto my hard disk that i watch alot (20gb). (i do this because i dont like it when i watch dvds from the disk, the dvd rom drive makes a very loud noise and since my pc is watercooled and virtually silent, the dvd spinning noise is very annoying. the big hard disk space hog, is my PVR. i use my pc as a personal video recorder, recording digital tv straight to my hard disk. i not only record stuff while im away, but many times i record movies and shows that i leave on my hard disk for storage for indefinite periods of time. my tv recordings account for around 130GB - approx 2GBs/hour of video. i also record music videos which get archived to another partition on my hard disk. without a doubt, i need more hard disk space. sometimes a program that i wanted to record hasnt recorded because i was out of hard disk space. current hard disk space = 200gb required hard disk space > 500gb ...for now.
  6. ive seen many posts of people reporting many hard disks failures. in fact, some people get through as many as 3 hard disks in 3 months. is it something perhaps that these people are doing (or not doing)? ive owned the following hard disks: maxtor 6.4gb - 5400rpm (no cooling) quantum 9.1gb - 7200rpm (air cooled) quantum 60gb - 7200rpm (air cooled) seagate bara IV 60gb (watercooled) seagate bara IV 80gb (watercooled) WD1200JB (watercooled) the only problem i had was with the seagates. however, once i changed the side of the hard disks that was being watercooled, no further problems. ive also built 2 pcs for my friends. using the following hard disks: ibm 75gxp - 30gb (air cooled) 2 x ibm 60gxp RAID - 60gb (air cooled) no problems with the above hard disks. now from the above, 9 hard disks, none have caused me any problems. the key to them all (except the 5400rpm maxtor) is that they have all had active cooling on them. so im hypothesising that perhaps, the main cause of hard disk failure could be heat related. do u guys agree or disagree? its just that i find it really strange that ive not had a single hard disk failure from 9 hard disks, all from different manufacturers (and please dont say its luck, 9 hard disks working perfectly isnt luck). perhaps if people who have hard disks fail on them could report the cause that they believe led to their hard disk failures. also perhaps if they could mention what sort of cooling they had, if any.
  7. was your wd1000bb actively cooled? after you took his 75gxp, were u actively cooling the drive?
  8. jcass, out of all the hard disks you wrote about, the ones i was most interested in were the maxtor d740x and the wd2000jb. this was because these are 7200rpm models, which is where i feel the active cooling factor comes into play. the older, slower rpm drives dont really need active cooling. my old maxtor 6.4gb 5400rpm hard disk would barely get warm to the touch. however, the 7200rpm ide models is what im most interested in. i noticed that for these drives you are using active cooling. i was thinking about adding 2 new hard disks to my system. i currently have 80gb seagate + 1200jbWD. i can get 2 120gb ibm 180gxp 8mb disks cheaply, however, im put off by their RMA service. however, from this thread it seems that maybe i may never need to call upon the RMA service of ibm (given that i will probably sell the hard disks on after about 18 months) - most people in this thread seem to be reporting good/reasonable reliability from their ide hard disks. ive just checked the reliability survey and it seems that the 180gxp series have worse reliability than the 75gxps the alternative is for me to replace my seagate 80gb with a wd1800jb.
  9. i tried watercooling my harddisks on their own loop. this enabled me to dedicate my entire watercooling system resources to just cooling the hard disks. the water temperature was much lower and allowed me to run the hard disks at around 20C. i didnt have any denim wrapped around the hard disks at this point and i noticed no difference in the noise, compared to when the hard disks are running at around 35C (which is the temps my hard disks normally run at).
  10. i experimented for one year, spending alot of money on different fans and rheostats, attempting to make my computer quiet. i overclock my pc also. once i switched to watercooling, the noise level dropped substantially and allowed me to overclock further. it was a more expensive setup though. once you hear a watercooling setup built with its first objective to reduce noise, you will realise that even your pabst fans running at a low rpm simply cannot compete against a watercooling setup. perhaps if you have a friend who has a watercooled setup, within 60 seconds you will be shocked how much quiter the watercooled system is in comparison to any air cooled system. i watercooled my hard disks as they were making too much noise. the only way to make them silent, was to wrap them up in denim material. however, this would lead to excessive heat build-up. attaching waterblocks to the hard disks, sorted this out. using my current setup, i think i can even run a scsi 15k rpm hard disk in complete silence.
  11. yep, the pcb side is covered with the sea shield, but nevertheless, cooling that side of the drive (even with the thick seashield) has led to no problems. while cooling the other side of the drive (and not the pcb side), led to alot of problems/headaches.
  12. the drive, at the time, wasnt mounted in my case; it was sitting outside the case, while i installed win2k. after win2k installation, i would mount the waterblocks to the hard disk and pack the hard disks into my case. while the hard disk was outside the case (and installing win2k) i felt the metal part of the hard disk and this was hot. i also felt the "black chips" on the pcb side of the hard disk. these too were hot. this may have been dangerous, but to this day, ive had no problems with that drive and i had saw no ill effects while i was groping the hard disk in the above way.
  13. also, just another point to consider about heat and hard drives. here is story involving my 2 seagate drives (i only have one now). i used to watercool the non pcb side of the seagate drives, however, DTEMP gave an internal temp reading of never more than about 36C. so the drive casing itself was quite cool (cooler than when i was air cooling the hard drives). however, i got lots of errors. i would get messages saying that the drives had been removed and partitions couldnt be recognized. when i would reboot, the drives would sometimes not get recognized. in the end i was getting ready to RMA the drives (one at a time, cuz i couldnt be without both hard disks at the same time). then when as a last resort i tried something: i flipped both drives around, such that the PCB sides of the hard disks were now being cooled. the internal temps of the hard disks stayed around the same however, not a single error. no problems at all. since then ive replaced one seagate with a wd1200jb, but the other, which was giving problems, has now been running problem free for about 6 months (the drive itself is about 15 months old). so from this i gathered that it is more important to cool the PCB side of the hard disk (which contains all the chips and controllers). if these things get hot, then your hard disks can behave unpredictably. so as far as im concernced, heat is most definetly a factor when discussing hard disk reliability.
  14. so to summarise, we are saying that apart from luck, the following can have an effect on hard disk life heat handling/shipping/installation technique psu quality wildly fluctuating electricity supplies is this about right?
  15. unfortunately im using an alumunium waterblock to cool my 2 hard drives that i have at the moment. however, you can buy (in the usa at least) copper hard disk waterblocks. i believe they cost around US$75. you can read about my hard disk watercooling in the link below: http://forum.oc-forums.com/vb/showthread.p...&threadid=81923 btw im using copper cpu, gpu, chipset blocks. AL hard disk block and radiator. im using water whetter to slow down corrosion. ive had this setup for a year now and all is fine so far.
  16. perhaps the reliability survey should have an extra field where the users can fill in whether or not the drives are/were actively cooled or not. this would give us a much better idea of whether or not active cooling can actually increase the life of a drive or not. perhaps Eugene could implement this?
  17. is there anyone here then who was actively cooling their hard disk and had a failure. cuz people who have reported failures (above) have all said that they havent used any sort of cooling. im just trying to find some sort of pattern, cuz im not the sort of person who believes in "luck". you make your own luck. btw i recd my wd1200jb wrapped in some bubble wrap (no 1" thick sponge). it wasnt shipped in ideal conditions. the drive has served me perfectly for the last 9 months...and counting. the way i see it is that if a drive was shipped/handled badly, it will either be DOA or it will run ok for a few days then fail. it wont fail after a year or so due to bad handling. the 75gxp/60gxp drives were failing after a whole range of durations (from DOA to a couple of years). also did anyone notice in the reliability survey that the 75gxp are actually more reliiable than the 60gxp. so ibm released the 75gxp, then they went and released an even worse drive. this must've cost them an arm and a leg to deal with all those RMA's!
  18. aaah. but i watercool my hard disks, further more watercooling the hard disks enables me to wrap up the hard disks in denim. this allows me to completely isolate the disks from any part of the computer case, hence no vibration, but also no passive cooling. when i did air cool my hard disk, i used to cool it cuz i heard many other people recommending that this be done. ive had 0 hard disk failures. whether this was as a result of cooling the hard disks, i know not. where are the people who had lots of hard disk failures? they dont seem to be coming on here and explaining the circumstances under which their hard disks failed. i read some people who would go through 3 hard disks in the space of a few weeks. could someone who had this experience please post and give us the setup under which the failure occurred. thanx.
  19. but have u actually tried touching the hard disk while it is in full flow? eg try transferring a bunch of files (say 2gb worth), transfer from one folder to another, then try touching the pcb side of the hard disk. it was only when i started installing win2k that i noticed this "extreme" heat. although your case temp might be 35C (or lower) this doesnt mean that the casing of the hard disk isnt way way way more higher than that. in fact, when i touched the hard disk, i was running it outside the computer case (i was installing win2k on it, before i installed the hard disk into the computer case, with its waterblock. i just wanted to make sure the hard disk was in full working order before i went through the hassle of waterblock attaching). so while the hard disk was too hot to touch, the ambient temp that the hard disk was operating in was well below 20C!
  20. have u guys ever felt the surface of your hard disks, while in operation? cuz my wd1200jb was so hot (when no cooling was used and i was intalling win2k) that i couldnt keep my finger on the pcb side of the hard disk for longer than 5-10 secs. now i cant believe that without cooling, this hard disk would still be functioning today. Now alot of people dont use any cooling and surely its because of this that alot of hard disks (that get as hot as my WD1200jb) may actually be failing. might i suggest that before people leave their hard disks running (and closing the lid of their computer case) that they at least check for excess heat buildup on the surface of the hard disk casing. btw my seagate baracudas are alot cooler than the wd1200jb. they get warm, but not hot.
  21. why does the reliablity database not allow us to enter our reliability results for the MAXTOR DIAMONDMAX PLUS 9 series of drive? are there any plans to add this in the near future? or perhaps i am missing something and the drive is already listed under a different name?
  22. im not being funny, but why does the reliability database only include drives that have been reviewed by storage review? is there a reason for this? i honestly cant think of any reason why this should be.

    dm +9 review

    the impression im getting is that the 60gb maxtor DM +9 is very unreliable. i would love to see this drive in the reliability survey.
  24. im actually going to use the raid controller on my abit it7 motherboard. this apparently is good for larger than 137gb drives. thanx
