![]() ![]() These drives are squeezing 500GB of data on each 3 ½ platter surface! Most folk have no comprehension of the incredible tolerances these drives must be capable of maintaining in spite of changing temperature, vibration, and drift due to repeated erase/write operations, etc. I finally purchased a pair of WD 2TB drives to use in my Antec case (they seem to be quite happy mounted on their edge). Each time this has happened (3 times so far) the clicking stops IMMEDIATELY after they are laid flat. ![]() They will then work quietly for another 2 months or so. The clicking continues until I open the case, remove the drives, lay them flat and access each sector once while it is laying flat. Then they each (within minutes of one another) will begin to click and chatter. I found that if I lay my new drives down flat and perform a full LONG format prior to mounting them up on edge they will function properly mounted up on edge for about 2 months of continuous use. I own an Antec Fusion Black media center case that has a spot up front for mounting two SATA drives up on edge side by side. HOWEVER the moment they are laid down FLAT they settle down, become quite and xfer data at 90mb/sec or better (while clicking they often transfer data as slowly as 20mb/sec). The actuator on the drive head arm assy simply can’t overcome the effects of strong vibration, which causes head alignment to be off enough to cause the drive to re-seek in an attempt to regain proper alignment.ĪLL of my 12 drives plus several others I returned for exchange (because of clicking and slow data xfer while clicking) have a hard time operating properly if they are mounted on their edge, or mounted vertically on one end. Excessive vibration causes a “dithering effect” on the head arm. I finally realized it was the VIBRATION from the fan being transferred through the aluminum frame (into the drive frame) causing the problem. I flipped the drives end for end in the tray thinking there might be some sort of electrical interference with no improvement. I returned the original drives for replacements TWICE with no change. If I crank the fan speed up past about 3500 RPM *BOTH* of the drives chatter and click incessantly. The drives are mounted flat in the tray and the tray has an adjustable speed cooling fan bolted to one end. One of my computers has a pair of 2TB drives stacked on top of one other in a removable aluminum tray. The clicking appears to be caused by more than one source. I have struggled “a bit” with the clicking on all of my 2TB drives. I currently own 14 of the Seagate 2TB 5900 RPM drives and 24 of their 1TB 7200 RPM drives. To “Force” an upgradeģ.On the option screen (where you can try an auto upgrade) press + to break to the command line. If not successful you will have to “Force” it. You may also need to change the BIOS settings to ATA mode if it is set to RAID or AHCIįirst you may attempt to upgrade the disk automatically, simply follow the onscreen instructions. ![]() You need to connect the disk to a native SATA controller I used an older desktop machine, removed the main hard disk and plugged in our ST32000542AS drive. Upgrade procedureįirst download the ISO upgrade image here Seagate suggest that customers can use the “Force” method to upgrade their disks. However, all drive serial numbers within the family product range are not detected as requiring the firmware upgrade by the tool. The new firmware is advised for all customers with drives which have the following model numbers ST3500412AS, ST31000520AS, ST31500541AS and ST32000542AS, see here. There seems to be a lot of confusion out there on the Internet about the firmware upgrade procedure. Seagate instead recommend their Constellation ES hard disk for higher RAID levels. It is unfortunate then that we are running a five disk RAID 5 array. Seagate do not recommend these drives in anything other than “Desktop RAID”, meaning RAID 1 or 0 between two disks only. We initially chose these particular Seagate disks as they are on Synology’s approved disk list plus offer low power, low heat output suitable, so we thought, for nearline storage. While Synology issued us a patch that seems to have resolved the issue they highlighted that our disks, Seagate 2TB model ST32000542AS firmware CC34, were not running the latest version. We have a Synology DS1010+ diskstation that has been having trouble maintaining a iSCSI link to a server here at work.
