similar to: One disk speed problem [SOLVED], and a question on hdparm

I need to disable the spin-down on an external USB drive because it spins down spontaneously while in use. The drive forgets the spindown-disable state across power outage so I need to reissue the hdparm command with each boot or hotplug. Where should I put the hdparm command to do this?

Can someone please explain what's wrong here. And how to solve it. I run CentOS-4.1 MSI K8N Neo Platinum Athlon 3000 Seagate Barracuda 7200.7 S-ATA disc [root at amd64 kai]# /sbin/hdparm -tT /dev/sda /dev/sda: Timing cached reads: 2808 MB in 2.00 seconds = 1402.81 MB/sec HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device Timing buffered disk reads:

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

Hi, I was wanting to run the equivalent of "hdparm -Tt /dev/hda" except on a SATA hard disk. What is the equivalent command for an SATA drive? I was wanting to see what kind of speed I am getting on the SATA drive. thanks, Jerry

Hi list, I googled around but couldn''t find anything on whether someone has good or bad experiences with the Caviar *Blue* drives? I saw in the archives Caviar Blacks are *not* recommended for ZFS arrays (excluding apparently RE3 and RE4?). Specifically I''m looking to buy Western Digital Caviar Blue WD10EALS 1TB drives [1]. Does anyone have any experience with these drives? If

smartctl, hdparm, and sdparm all are valuable tools to obtain hard drive info. But, they don't seem to work, at least, on obtaining hard drive info from drives on a Dell PERC controller. Instead, I'm given basic PERC controller info, not drive info. Is there a tool to let me get the hard drive make/model/serial numbers from a hardware RAID setup? Thanks. Scott

I know that this has been well-discussed already, but it''s been a few months - WD caviars with mpt/mpt_sas generating lots of retryable read errors, spitting out lots of beloved " Log info 31080000 received for target" messages, and just generally not working right. (SM 836EL1 and 836TQ chassis - though I have several variations on theme depending on date of purchase: 836EL2s,

And now the hard drive performance goes down

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would

We add disks to an LSI raid array periodically to increase the amount of available space for business needs. It is understood that this process starts with metal, and has many layers that must each adjust to make use of the additional space. Each of these layers also says that it can do that 'online' without interruption or rebooting. But making it happen is not that easy. When the HW

Hi, I don´t think that this is a ext3 Problem, since you have problems partitioning that disk. Perhaps a hdparm -i /dev/hdX could shine some light on this, also a fdisk -l /dev/hdX could be useful. For now - let me guess: <guess> To me, it seems, that the disk is clipped to 32GB, perhaps the mainboard bios can not cope with a disk >32GB - just a thought. Since the manufactorer

Hi, I have two 320 GB SATA disks (/dev/sda, /dev/sdb) in a server running CentOS release 5. They both have three partitions setup as RAID1 using md (boot, swap, and an LVM data partition). # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdb2[1] sda2[0] 4192896 blocks [2/2] [UU] md2 : active raid1 sdb3[1]

Hi there: As suggested in the docs, I am forwarding a bug report. I have just converted two partitions to ext3 from ext2 without reformatting on my home box. All is not well, however. Here's the specs AMD K6/2-3D 500 Mhz, 64MB SDRAM, 100 Mhz bus Via Apollo P5MPV3 chipset, 100 Mhz bus Opti Mad 16 931 soundcard Video= AGP S3 Trio, w/8MB RAM, PS/2 mouse. Realtek 8029 pci bus network card.

I've got a brand new .5U P4 system running several (I think) Seagate 80gig SATA drives. I tried to copy data from the first drive (sda) to the second drive (sdc) and was only getting about 1.7megs/sec. So I figured DMA was off. And this is what happened when I typed "hdparm -d1 /dev/hdc": /dev/hdc: setting using_dma to 1 (on) HDIO_SET_DMA failed: Operation not permitted

Hi, I run a little router/firewall that also acts as a print server for the linux and win98 clients on the LAN. I have the harddisk configured so that if there is little activity, it spins down (hdparm -S 12 /dev/hda). I added smbd/nmbd today and with the two services running, the hard disk drive spins down but wakes up about every 12 minutes. Without the services, only a major event causes them

Hello again. Do any of you have one of the 'new' HDDs with 4kB Sectors currently in use? I would upgrade to the 4kB disks but I don't know if this might be problematic as I intend to use ZFS w/ RAIDz or at least a classic RAID6. How might this affect performance under 5.5 and how do I go about setting up the alignment of the partitions I use? Kind regards Dawid Horace
