View Full Version : HDD very noisy during recording - KISS-DP558
Recording with my Kiss-DP558 is very loud!
U can hear the player working all over the room, especially during silent parts of a film this is really annoying!
If I play movies from Hard Disk I can hear nothing!
Is this normal?
Plz tell me your opinion and experience about that!
To me it seems like a bad HDD. It should not be hearable according to me. I can't hear mine if I don't come really close to the player.
No loud noise over here....
Yep mine is pretty noisey, but it seems to work ok. I just thought it was a 'feature' :?
It depends on how fragmented your drive is.
We recorded and delted a lot of files, recorded again and deleted and after a while you hear the noise...
We already are looking at KiSS for some sort of defragmentation...
(or when the disk is completely empty, you can always format it)

I have exactly the same expeirence. But as High Jack says you can try to format the HDD. It's helps a lot but unfortunately only for a short time.
Hope they can make a better solutions because I have never heard so much noise from a HDD recorder before, so something must be wrong.
hmm I am sure that being defragmented will cause more disk activity but mine has been noisey since new and from a formatted disk. If the disk does fail in the 558 is it an easy thing to replace, or does it have to be an exact model etc?
Many models will work fine on the kiss player.
Advised however, is using the same if needed...
GrEeTz
do all the Kiss 558 players have the same harddisk model? brand?
It's well known that some harddisks make more noice than others. (like Western Digital)
The samsung spinpoint is very good one ( price, noice level)
For some harddisks you have a silent-mode. Perhaps it's not activated on yours...
The DP-558 uses the samsung spinpoint (as far as i know)
I will make some internal pictures during the week... :-)
for the spinpoint there is a tool to set the harddisk in quiet-MODE

Don't know if it's already activated on the harddisks of the Dp 558.

Has anybody tried this? Any luck?
Anyway, it should not be nescessary to do this. The noise during recording must be caused by the logic that controls the writing process. I suspect the drive of updating a FAT table every "very few" kilobytes. When the read/write head of the drive moves from track to fat, it makes a noise. When the drive is clean, it does not need to move very far = not much noise. When there's some gigabytes of data on the drive, the strokes are longer = more noise. I don't think fragmentation is the issue!
Best would be to use a write buffer, like in any pc, making the drive write larger blocks of date BEFORE updating the FAT. Either this is not possible on the 558, or it was not thought of... I hope it can implemented in a future firmware update (but please get FF during recordings done first!!!).
You are probably right, but I suspect that also the maintenance of the *.idx file results in head movements. This case in allready in the bug track list together with, besides others, my comment on this.
My suggestion was to maintain the .idx file in RAM disk, and then save it to disk when it reaches a certain size or at the end of the recording.

Well the filesystem is not FAT, it's the one used by Linux (ext2?). And they probably dont control such low level stuff and let the OS take care of it (Linux).
My HD used to be very noisy when recording back with 1.03 but now I cant hear it anymore with the latest fw.

This is not the problem since I can hear my hdd if I'm very close to the player, but it is very quiet. The head must be able to move without making that much noice. We should ask KiSS about this and they should clarify why some units are disturbingly loud when using the hdd.
To start tampering with the idx file will probably just introduce more bugs. Instead we should find out the source to the problem and not trying to walk around it.
