Ashley -- Ashley Reynolds [EMAIL PROTECTED] Interesting Interesting indeed. I haven't bought a Seagate since lost interrupts and install freezes with them back about 6.1 and 7.0 time. At the time, they were totally useless for any VIA chipset board with kernel 2.2.

With IBM in the toilet at present, and Quantum gone, I am looking for something I can use besides Maxtor, because I hate to place reliance on a single brand.

Re: [expert] Hard drives: any thoughts?
I've generally had good luck with Fujitsu's but did run into an interesting problem with a 6 gig version of it. We bought a lot of 100 of the drives with a previous company I was with. In the production line the drives had installed on them a whopping 75 megs of FreeBSD and our software. Normally a drive to drive clone took on the order of 30 minutes (multiple drives on the receive end would slow it down somewhat) What we did run into was 2 cases of drives (12 to a case) that were the slowest clones I'd ever seen 16 hours to write 75 megs (limited production test in our shop run once a problem had been found on the line.) and format the drives. Once they were finished they ran just fine. As long as you never had to write to them again. A 100k copy from cd to HDD could take 25 to 30 minutes. Fujitsu sent out a rep to look at the problem we had and left us two cases of 10 gig drives for our trouble. (The gesture was appreciated but 6 gigs was already overkill.) Never did find out why but it seemed to be a bad lot.

I've got a question at the end. Actually, we are talking about data rates very differently From/To the attached electronics and disk, the data is _pure serial_ Under any one head there iare 258048 bits of usable data in a rotation... And this rotation occurs in 1/7200th of a second or about .139 ms, so if an entire track is read, we have about 1.86 GBITS/s (that's Gigabits/sec using 10^9) or 1.73Gbits/sec (using 2^30) Now the controller is capable of passing data at what? How is that rated? Is it bytes/sec, words/sec. bits/sec, or just a clock rate that is advertised? The advertising is usually careful NOT to say. In fact it appears to be a clock rate. Now we have to look at the pcide bus The AT Attachment with Packet Interface Revision 6 Draft says there are 16 data bits. What does that mean in raw bit rate? Hmmm lessee, there are many sorts of messages crossing that bus, not all of them data, and to every 512 bytes there is appended a 57-byte CRC packet so let's agree to knock off about 10% for necessary cruft to preserve data integrity--it's a little higher than that but so what? 133MHz (ATAPI-6) less 14Mhz is 119MHzx16bits =1.9GBITS/sec or 1.77Gbits/sec WHOA Until we have 1rpm disks for IDE it looks like we can transfer data a little faster than it can spin on or off the disk But that's OK we can build up the data for a burst in an onboard buffer or seven so that many tasks can be happening apparently simultaneously Now the PCI bus is 32 and the extended PCI bus is 64 bits wide Hmmm the IDE channel is only 16 bits wide so to use the PCI bus to capacity, we need 4 times the clock rate or 4x33 or 132. Sheesh, seems we are at the max that can work with an essentially unbuffered transfer from memory to disk... but of course the buffering is already there for the next of the components that advertises a speed increase. Now look as the fractional nanosecond values of signals for spooling data and recall that once a cylinder boundary is reached (at 63K for single-platter two head disks) we have to talk about stepping the heads, and now we are talking milliseconds, a 10^6 order of magnitude change in data rate. That is why a buffer on the disk electronics is a great idea. The disk is the slowest component. RAID0, RAID4 or RAID5 can make a real difference in the apparent performance of disk transfers by making stepping a less frequent event (with the right chunk size defined, of course.). Civileme I'm curious as to wether you have any recommendations for chunk sizes. Here's what I've got set up now: raiddev /dev/md0 raid-level1 chunk-size32k persistent-superblock 1 nr-raid-disks 2 device/dev/hde5 raid-disk 0 device/dev/hdg5 raid-disk 1 raiddev /dev/md1 raid-level0 chunk-size32k persistent-superblock 1 ___ I've got two identical IBM deskstars in place, with the prefetch set at 4k: ___ [root@tamriel elx]# hdparm -a /dev/hde /dev/hde: readahead= 8 (on) ___ Hdparm gives the following information: [root@tamriel elx]# hdparm -i /dev/hde /dev/hde: Model=IBM-DTLA-307030, FwRev=TX4OA60A, SerialNo=YKEYKTYJ069 Config={ HardSect NotMFM HdSw15uSec Fixed DTR10Mbs } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=40 BuffType=DualPortCache, BuffSize=1916kB, MaxMultSect=16, MultSect=16 CurCHS=16383/16/63, CurSects=-66060037, LBA=yes, LBAsects=60036480 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=yes: disabled (255) Drive Supports : ATA/ATAPI-5 T13 1321D revision 1 : ATA-2 ATA-3 ATA-4 ATA-5 _ The question I have for you is, could I better optimize the system with chunk sizes other than 32k?

Go to http://www.mandrakestore.com remember we have a 63 sector track with 512 byte sectors 31.5k and we usually have two of them 31.5+31.5 =63k So 64k chunk is a bad idea if you have single-platter drives--every chunk represents a head step before a drive switch. And 32 k chunk means drives switch once before the head steps-cutting stepping events in half, and they are more than 90% of the time spent by drives in accessing. Hmmm 21k sounds even better, cause you switch switch switch switch switch switch then a read makes the heads step... This could destroy threading of drive requests though. I think 32 is a good starting number,

Yes...very interested. Master Jedi Dfox may be interested as well. ;) Yeah, it might prove interesting. I've heard people network to them and control them from Linux. I wouldn't be suprised to see a regular PC like drive in there. My brother recently took apart a spare Dish Network controller (similar to Tivo in the digital recording dept) and just added the drive to his spare computer. I didn't ask him what brand the HD was. He did notice wierd 'formatting' problems from time to time, but probably that was software - like frames of the Simpsons coming up during a recording of wrestling or what have you.

Until about a year ago IBM drives were renowned for their reliability, and I used to recommend IBM to all my friends. Since then, they have suffered reliability problems, and the return rate for IBM drives has been high. There was even a class-action lawsuit launched against IBM last year, since so many people's drives failed (I think this was settled out of court). IBM have been first to develop and implement all sorts of new technologies, including glass platters and that 'pixie dust' stuff. It looks as if they're having major teething problems with these new technologies. There was some controversy a few weeks ago when IBM placed warnings on their new drives indicating that they shouldn't be used for more than eight hours per day. If that isn't an indication of poor reliability, then I don't know what is. With all these quality control problems, and IBM's recent financial woes, I am not surprised that they have decided to sell their hard drive unit to Hitachi. I have a 60GB Deskstar that I got in late Dec. It is not the 60GXP, which is the drive that IBM had the QC problem with but is based on either the 75GXP or the 120GXP, most likely the 120GXP. As to the 120GXP itself the following is from the WatchDog column of this months (June/82) issue of MaximumPC Mag IBM got into hot water with consumers when it published a spec sheet with a 'power-on' rating for its popular 120GXP hard drives.The spec suggested that the hard drive could be safely left on for a total of just 333 hours a month. The Dog's investigation has discovered that, despite the published 'power-on' spec, IBM designs and tests its hard drives to withstand 24 hour-a-day use, and honors such use in its warranty. IBM has since redacted its spec sheet to remove the inflammatory power rating. Currently I have 6 systems running 24/7. Of 15 hds, 9 are IBM Deskstar and 7 are MaxtorPlus. The drives ages range from 5 years to 6 months. In that 5 year span I have suffered only 1 hd failure, a Maxtor, which was replaced. When in the market for a hd if it is on sale or I want 1 today I get the MaxtorPlus retail box (IBM is not available locally). If purchasing on the net I go OEM IBM Deskstar. In my book they both rate as equals in outstanding quality and performance, and with the 1 exception I have yet to be disappointed by either.

The funny thing is that the Linux swap partition on that same drive poses no such problem.

I have had very little success with seagates, but the last seagate I bought was back in around 1991 :(. My older Maxtor drive lasted nearly 7 years before I took it out - I probably could plug it back in now and it would still work like it was brand new (ca. 1993 brand new, but wtf). My other drive (1.6 gig maxtor) is pretty clean, but there have been one or two bad spots on the drive surface since I got it back in 1996, so right now I'm just using it for /var.

It's quiet, I've never had a problem with it, and it's plenty fast. I know of all the IBM hard drive problems, however where are these WD problems comming from? NB OK Firest of all, WD is made about as cheap as possible. It has a single platter and two heads, which makes the track density about as high as the technology will allow. Other manufactirers tend to use more platters and more heads, and sometimes dedicate one head to clocking the data on the others. WD reps have stated unequivocally at several shows that they DO NOT support linux at all, only Windows and Solaris. That tends to indicate that there is something seriously out of spec with there stuff since they are unwilling to risk broad scrutiny with highly optimized linux drivers. It also suggests that they have submitted their own drivers to those op systems which tend to cover deficiencies in hardware. My experience with WD drives includes a WD200AB which ran on a RedHat system at a whopping 1.62Mb/s when set to UDMA66.. I tinkered with the settings using hdparm and eventually settled on UDMA33 with a performance increase to over 9M/s. I use a WD64AA to reproduce disk errors and find workarounds for support purposes. It does signal service. I can always count on it for Seems like memory missing as install crashes hda: lost interrupt 0x51 {DriveReadySeekComplete} Type errors on a randomly occurring basis. I know if I can tweak the chipset and the kernel to manage that drive, I can tell the customer what to do to get running, besides swapping out his horrid disks. WD has an extended track record of failures and bad drives. I once called them about a faulty drive, and it was the smoothest sales experience I EVER had. They obviously do not short their customer relations department. But then that is spending money to do over the job that wasn't done properly the first time, and seems to me to be a scary mismanagement. Build it right the first time,,, An airline tha has a VP in charge of lost luggage would scare me just as much. Now, on to facts about testing by Mr. Linux-ide himself. http://kt.linuxcare.com/kernel-traffic/kt2214_54.epl#2 Yes, it is not recent, but WD hasn't changed. They still have odd timing and they still have a very bad workaround for leaving out the hardware to do 57-byte CRCs and the result is a noise in transmission from the computer becomes a permanent error on read-back. The blow-off makes it look like the drive is faster but at the expense of a gamble on data integrity. Anyone around computers for a while knows that if an error has nonzero probability, it doesn't matter what the odds against it are, it WILL occur, and the probability only tells you how often to expect it. And the hardware/software implementation had better chack for it and setup a recovery. And WD seems to rely on the low probability, which is just how Andre Hedrick characterizes it. And I am still seeing 8 times as many reports of problems with install or stability from WD owners as from Seagate owners. I rarely see any from Maxtor owners, and even the slew of reports lately from owners of recent IBM disks who are running them 24/7 does not match the continured high level of complaints (about our OS) from WD owners.

I think it was something about the heads getting stuck to the platters. While they kept spinning, or during very short power downs, everything stayed warm and smooth, but when they got cold... Anyway - sounds like what happened to you. Sounds like a good reason for a UPS - well, another good reason. Remembering back to the days when HDD's were measured in pounds. I could suggest this as a probability. We had some old AMPeg (yes AMPeg) HDD's about 50 meg I believe that had trouble spinning up if you ever shut them down. When they were new, no problem. But over time the motor that spun the platten lost tourque. So it had a lot of trouble starting the platten to spin. Once it did it would run forever. So this system was the only system on site that was allowed to run 24/7 and the only computer that was on the full backup system for power (battery, genarator and additional methods) I'd be inclined to believe that it was a motor failure probably caused by heat not a case of heads attaching themselves to a platten.

It is not the 60GXP, which is the drive that IBM had the QC problem with but is based on either the 75GXP or the 120GXP, most likely the 120GXP. As to the 120GXP itself the following is from the WatchDog column of this months (June/82) issue of MaximumPC Mag IBM got into hot water with consumers when it published a spec sheet with a 'power-on' rating for its popular 120GXP hard drives.The spec suggested that the hard drive could be safely left on for a total of just 333 hours a month. The Dog's investigation has discovered that, despite the published 'power-on' spec, IBM designs and tests its hard drives to withstand 24 hour-a-day use, and honors such use in its warranty. IBM has since redacted its spec sheet to remove the inflammatory power rating. I remember reading this, but I could not remember the source of the information; thanks for posting this ! Currently I have 6 systems running 24/7. Of 15 hds, 9 are IBM Deskstar and 7 are MaxtorPlus. The drives ages range from 5 years to 6 months. In that 5 year span I have suffered only 1 hd failure, a Maxtor, which was replaced. I have owned several maxtors and samsungs, and the worst failures I have ever experienced have been with samsung drives; this was both IDE and SCSI versions. After my last Samsung experience I vowed never to buy another Samsung again. The Maxtors were not as reliable as either the IBM's or the Fujitsu's. I have two Fujitsu's here that are still working after 6 years. If indeed I was forced to make another buying decision other than IBM (which I'm not totally convinced I need to do yet), then I believe I would go back to Fujitsu. I would not go back to either Seagate, or Western Digital; I don't think that the quality is there. Maxtor is still a big maybe. Before that I'd go with either Hitachi or Fujitsu. For now, unless I or someone else really gets burned, I will probably stick with IBM. Especially since you reminded me of the Watchdog article in MaximumPC, Charles. When in the market for a hd if it is on sale or I want 1 today I get the MaxtorPlus retail box (IBM is not available locally). If purchasing on the net I go OEM IBM Deskstar. In my book they both rate as equals in outstanding quality and performance, and with the 1 exception I have yet to be disappointed by either.

Form what I've seen, they're focused on the 'budget' market (OEMs, etc.). Hmm. Any idea what the set-top boxes might use (tivo, dish network, mp3 players etc.) ? One would seemingly want to have at least as good (if not better) reliability because these drives can easily get more usage (in terms of writes/rewrites) than the typical desktop or server machine. For instance, the drives in embeeded tivo-type devices are routinely re-recording a section of disk with new video as long as there is power to the machine. This is at least true with dish network combo digital video recorders/dish tuner boxes. Sridhar Dhanapalan Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com

Re: [expert] Hard drives: any thoughts?
Have you used any IBM drives made in the past year? Until about a year ago IBM drives were renowned for their reliability, and I used to recommend IBM to all my friends. Since then, they have suffered reliability problems, and the return rate for IBM drives has been high. There was even a class-action lawsuit launched against IBM last year, since so many people's drives failed (I think this was settled out of court). IBM have been first to develop and implement all sorts of new technologies, including glass platters and that 'pixie dust' stuff. It looks as if they're having major teething problems with these new technologies. There was some controversy a few weeks ago when IBM placed warnings on their new drives indicating that they shouldn't be used for more than eight hours per day. If that isn't an indication of poor reliability, then I don't know what is. With all these quality control problems, and IBM's recent financial woes, I am not surprised that they have decided to sell their hard drive unit to Hitachi. If you're wondering where I get all this stuff, it is The Register (http://www.theregister.co.uk). For me, IBM was a natural choice until this string of incidents. WD is out of the picture, since they don't correctly follow the ATA spec. That leaves Seagate and Maxtor.
