Q. When copying from SATA to SATA using the Disk Jockey and Disk Jockey Addonics SATA adapters, the green power LED is blinking but the red LEDs near the cable connectors that typically show disk access are not lit. Is the copy working?
A. Yes, the copy is working as it should but you are correct, the drive access LEDs are not showing disk access. We are looking into this issue and will hope to have some type of resolution soon.
Q. Can the DJ copy non-UDMA drives?
A. No, unfortunately the DJ only works with UDMA drives. If you need to copy non-UDMA drives (including PIO devices) please look at our Solo III product line.
Q. Can the DJ copy Compact Flash drives if I buy the right adapters?
A. Unfortunately the answer is no. It's not so much of a connection issue but more of an issue of what type of devices the DJ supports. Currently the DJ supports only UDMA drives (including SATA drives with a SATA adapter). Compact Flash devices transfer data in a mode called PIO. The DJ does not support PIO mode. If you are interested in copying Compact Flash devices please take a look at our Solo III product line.
Q. How can I tell if my hard disk drive is UDMA?
A. Unfortunately most drives do not say on the label whether or not they are DMA or UDMA. You can typically find this information by performing a quick Google search (www.google.com) on your drive's model number and reviewing the drive specifications. A good rule of thumb, however, is that typically a drive larger than 6 to 8 GB is UDMA, and typically the smaller drives are not. That's not always the case, please check individual drive model specifications for exact information.
Q. A couple of my 20 gig drives could not be seen by the unit when set to Master - If i set them to cable select I can see them ok and copy away without problems, is this OK - are there more chances of errors if I copy with both source and destination drives set to CS?
A. Well, this was an actual question posed to us from Steve across the pond in the UK. Our answer was, "duhhhh, ahhh, we don't know? Give it a shot!" Sure enough Steve did and sent us this reply. "I have now replicated and tested 7 HDD's ranging from 10 to 120 GB - all have been 100% sucessful using the cable select method." So there you have it, tried and tested! Thanks, Steve!
Q. Once I copy a smaller hard disk drive to a larger hard disk drive on a PC, how do I make the rest of the space on the new disk available for use?
A. <NOTE - This process will only work on NTFS formatted volumes> We have tested this process in the Diskology laboratory running Windows XP, although it should work with Win2K as well.
- Open a command prompt window (Start Menu->Programs->Accessories->Command Prompt)
- Enter the Diskpart utility (type the command "diskpart").
- List the volumes available on the system (type "list volume" at the DISKPART> prompt).
- Select the volume to expand (type "select volume #" at the DISKPART> prompt - where # is the volume number displayed in the volume list).
- Expand the volume to include all free space on the disk directly after the selected volume (type "extend" at the DISKPART> prompt).
- Unless DISKPART reported an error, the volume will be extended (type "list volume" at the DISKPART> prompt again and it will show the new size of the volume).
- See next question if all else fails.
Q. (from a real, live user) I did the above steps and it didn't work? What did I do wrong? We threw out the number 1 tech response to this type of problem, "we've never seen that problem before, can you try to do it again?" to which the customer replied (thank goodness!)...
A. I found a fix for this problem because we have had this problem more than once. After we copy a disk using the Disk Jockey and the free space will not show we then boot up into the Win XP disk utility and let the Win XP format
utility find the hidden free space and we then format it (Quick) and then reboot into XP and the free space shows up in my computer.
Q. I've tried both of those suggestions and I STILL can't reclaim the extra space, what can I do next?
A. This is a tough one. We have not been able to NOT successfully expand in our lab. We have had a number of customers tell us that a 3rd party partitioning utility will allow you to expand rather easily. For those of you who do not own a 3rd party partitioning utility or would prefer not to purchase one we did receive this email recently which offers some hope for those still unable to expand...
"We found a solution that you might want to put in your solutions page. We found out that the expand command does not work on the boot partition. When we removed the drive and installed it as a slave it worked fine." -- Scott
Q. I noticed in the manual for the DJ that is said it could not be used to start up a machine from a disk attached to it via FireWire, but I don't seem to have any trouble with it doing that at all. I've tried Mac OS X 10.3.8 - 10.4.2. All I did was go into the System Prefs and select a system on a drive that was connected to the DJ and it starts right up without any complaint!
A. OK, you can say "I told you so!" and we'll gladly say we blew that one. Surely that part of the manual was written by someone incompetent who is no longer with the company (wait, we're all still here!). OK, we have no excuse, but happy starting up off of another drive attached to the DJ!
Q. Once I copy a smaller hard disk drive to a larger hard disk drive on a MAC, how do I recover the extra space on the larger drive?
A. The bad news is that the Macintosh OS does not support this natively as the Windows OS does. The good news, no, make that GREAT news is that we've teamed up with the fine folks at SubRosaSoft to create a product called the Disk Jockey Expander! This simple software tool for OS X helps you recover that extra disk space in one easy click. It's so easy a marketing guy can actually do it! No, really! For more information, check the press release on the product or visit the Diskology store.
Q. Is the mirror mode dependent upon using the ribbon cables or can both drives be hooked up to the firewire ports on the disk jockey while the USB port is hooked up to the computer.
A. Great question! We get this one a lot. To mirror drives they must be hooked up to the ribbon cables. When you have the DJ in mirror mode it shows one disk on your desktop (for Mac folks) or under My Computer (for you PC peoples). When you write data to the disk it is simultaneously written to both drives attached to the Disk Jockey. Unfortunately we CAN NOT mirror the internal hard drive simply by connecting a disk to the ribbon cable, mounting up via USB or firewire and switching to mirror mode. Now, with that said, wait till you see what we're working on! Yes, a pretty cool piece of hardware that WILL let you mirror your internal drive to a removable drive located in a slick 3.5" drive bay! If you want to know when it will be ready, just drop us a note at email@example.com.
Q. Small elves have come into my office and apparently cleaned it! I now have an area which contains about 200 different power supplies and I don't know which one goes with which gadget. What are the specs on the Disk Jockey power supply?
A. Small elves, eh? Anyway, the power supplies are manufactured by AK II Technology Co. Ltd., the specs are as follows:
Disk Jockey (original):
O/P: +12V/4.0 A
Output: +12V --- 4.0A
Disk Jockey Ultra Portable:
I/P : 100 ~ 240Vac
O/P : +12V/2.5A
If you still can't find it we would be more than happy to sell you an additional one, just email firstname.lastname@example.org.
Q. This one was a question and a solution by a customer that left us scratching our heads...but it fixed his problem so we thought we'd run it here... "I received the Disk Jockey this week and tried to make the first copy. I encountered a problem. The source disk had two (2) partitions, one with DOS and the other with QNX. The target was the same type with slightly bigger capacity. After the copy, only one partition was correctly copied. Help!
A. And we'll admit, we were ready to reply with "it should work!" when he replied back with the following...I found the cause of the problem. The reason the computer could not read the second partition was the default COMS setting did not work with QNX. After I corrected COMS setting, it boots up nicely with QNX on partition 2: The target disk was, in fact, perfectly duplicated.
Q. I want to use the Disk Jockey on Windows 98. Do I need any drivers?
A. You will indeed need drivers. Download them here.
Q. Can I replace the cables that came with the Disk Jockey and use longer cables?
A. Remember, like my grandpa used to say, "it's not the size of the cable, but it's the magic in it!" But with that said, the answer is essentially yes! We will soon be offering longer cables in sizes of 6 and 12 inches on the Diskology web store. We can even custom fit the cables on the Disk Jockey for you prior to shipping for an additional charge. Typically your next question will be...
Q. How long of a cable can I use?
A. Remember, like my grandpa used...wait a minute, I already used that one, didn't I? OK, grab some tape for the frame of your glasses, a pocket protector and a 2 liter of Jolt Cola because you're about to get inside the mind of a serious geek.
The maximum cable length you're meant to use for any ATA interface - any kind of modern "IDE" drive - is 457mm, according to the official specification. That's 18 inches. (you may have seen some advertised for sale that where as long as 36"! Those guys must be nuts!)
This length limit applies to 40 and 80-wire cables alike. 80 wire cables also can't be any shorter than 254mm (ten inches), by the way.
The 18 inch limit is why IDE is typically an "internal-drives-only interface" (which is one more reason why the Disk Jockey is so cool, because it's a rebel of a storage product! Breaking the law! Breaking the law!). You can run the cable out of your PC's case if you like, but it won't get far.
The spec mandates such short cables for two reasons.
Reason one - practically all IDE cables are unshielded. There's nothing around the conductors but insulation. Electromagnetic radiation goes straight through insulation. So external interference from the rest of your computer's giblets can influence the signal on your IDE leads.
Unshielded cables act like antennas. Generally speaking, the longer you make'em, the more energy they can pick up from their environment.
Reason two - IDE cables are unterminated. "Termination", in the electrical sense, is essential to provide "impedance matching", which in English is what you have to do to stop the signal from reflecting off the end of the cable like a wave that hits the end of a bathtub (but again, PLEASE do not copy disks in the tub!).
Electric current does not move instantaneously down a wire. It travels at nearly the speed of light (which is even faster than a 67 Mustang), but when you've got thirty-three and a third million clock pulses per second - which is the speed of the IDE bus - even light in a vacuum only moves a hair under nine meters per clock pulse (memorize that last line and use it around friends while pushing up said glasses onto the bridge of your nose, then pause dramatically, snort, and take a big swig of Jolt...you're a geek!).
So if you're fooling around with, say, a double-the-rated-length 900mm IDE lead, there's an end-to-end signal delay in it of about a tenth of a clock pulse. The signals you want your drives and your motherboard to be able to hear will be significantly blurred by delayed reflections from each end of the cable.
Transfer your data at twice or three times the UDMA/33 speed - as UDMA/66 and 100 do - and reflected signals get more and more out of step with the real signal, and do it more and more harm. So bottom line...Short Cable =good, Xtra Long Cable = bad!
Q. I'm reading a lot of news on the web about the Disk Jockey being used to upgrade the hard disk drives inside of a TiVo. How are people using the Disk Jockey with this process?
A. Many people are purchasing the Disk Jockey for fast, sector-by-sector hard disk copies. Inside of a digital video recorder (DVR), like the TiVo, you'll find a standard IDE hard disk drive. Typically the DVR's ship with smaller drives, usually between 30 GB - 60 GB limiting the amount of material than can be recorded to the DVR. Many people are "upgrading" their DVR's to include larger drives. The process is somewhat complex, however, at this time. One of the key steps is doing a sector-by-sector copy of the data that resides on the DVR hard disk drive to the newer, larger hard disk drive. Up until now, this has primarily been done by inserting both hard disk drives inside of a PC, booting up in Unix (or Linux) and completing the copy via software. The downsides of this approach are 1) copy speeds in software are very slow 2) you must have a PC with two empty drive bays 3) you must be comfortable opening up your PC and inserting hard disk drives.
Using the Disk Jockey, the small DVR drive is inserted on the "Disk 1" port, the new, larger drive on the "Disk 2" port. The Disk Jockey is placed in "Mode 3" or copy mode, and the copy is done in literally a matter of minutes, rather than hours. This has saved people a tremendous amount of time and effort for the copy portion of the upgrade.
Once the information has been successfully copied from the smaller DVR disk to the new, larger disk, the new disk must still be "expanded" in order for the DVR to recognize all of the additional space (which equals additional recording time). We recommend following the expansion steps found at this site http://www.newreleasesvideo.com/hinsdale-how-to/ .
Q. I have successfully copied several drives using the Disk Jockey, but I've encountered a strange problem. I was attempting to copy a 30Gb Quantum Fireball Lct15 (from a TiVo) to a new WD 120Gb drive. In copy mode, the first press of the blue button powers both drives and all seems normal. Immediately after the second press of the blue button, a quick beep is issued, followed by a half second or so pause, then three very quick beeps. The green LED glows steadily for about 1 second afterwards, then the Disk Jockey powers down. What does this mean? The quick beeps do not resemble the error codes that occur when a drive is not connected, and there is no mention of this in the manual.
A. The drive appears to be "locked." Note that not all TiVo drives are locked (as a matter of fact, in our research most appear to not be locked). Many times this will cause the drive to show up with a smaller drive size. You'll need to download an "unlock" utility from the web. Contact email@example.com for more information on "unlock" utilities. Used properly, the unlock utility will quickly show the drive at its full capacity in which it can then be copied to a larger drive. Used improperly and it can cause damage to the drive.
Q. Does the Disk Jockey support new Serial ATA (SATA) hard disk drives?
A. Well, yes! The mad scientists at Diskology have created a new Serial ATA adapter that will allow you to connect a Serial ATA (or SATA) drive to the Disk Jockey. This will let you copy data from a parallel ATA drive to a SATA drive or vice versa. It also makes for a nice conversation starter when left on the coffee table. The SATA adapter can be purchased here.
Q. Does the Disk Jockey support SCSI or Fibre Channel hard disk drives?
A. No, the Disk Jockey only supports traditional ATA (parallel ATA or PATA) hard disk drives. The drives must be Ultra DMA.
Q. Does the Disk Jockey support laptop hard disk drives?
A. Yes! The new, ultra portable Disk Jockey ships with two laptop adapter cables so no additional parts or pieces are necessary to copy from a 3.5" hard drive to a laptop drive or from laptop drive to laptop drive. For users of the old-style "white box" Disk Jockey a 2.5" to 3.5" laptop adapter must be purchased. You can purchase them from many places, we buy ours from ComputerGeeks.com.
NOTE - You will need to pull a pin on the adapter to have a correct fit with the Disk Jockey cables. If you need help with this or are not comfortable doing this please contact us for more information at firstname.lastname@example.org.
Q. What happens when copy mode ends in an error?
A. Please verify the HDD specs. Copy mode requires that both HDDs be UltraDMA compatible. Also, there is possibility that the HDD itself may have a problem. Here, we recommend you test the HDD in "check mode" first to verify there is no problem with the HDD itself, before copying.
Q. After copying from the boot HDD which includes a bootable operating system, is it possible to boot from the copied-to HDD?
A. Yes, it's possible. However, if the copied-to HDD is a different capacity than the copied-from HDD, there could arise a BIOS limit issue. If so, we recommend you check with the PC manufacturer.
Q. Is it possible to copy different capacity HDD's?
A. Yes, it is. However, the copied-to HDD will need to be greater than the copied-from HDD.
Q. If different capacity HDDs were copied, what happens to the extra capacity of the copied-to HDD?
A. It is treated as unused space. Under WindowsXP and Windows2000, it's possible to use this additional capacity. Under Windows9x, if the copied-to HDD has assigned the additional space as expansion space, then it's possible to use the copied-to HDD's additional space as an expanded space. If the copied-to HDD has already pre-assigned this additional space, then it must first be deleted before being assigned as expanded space.
To reclaim the additional space on a Macintosh you'll need to purchase a copy of the Disk Jockey Expander for $24.95. Unfortunately this functionality is not built into the Mac OS however it can be done in just a couple of clicks with the Disk Jockey Expander software.
Q. Is it possible to copy hard drives of different specifications (rpm, cache memory size, manufacturer, access time)?
A. Yes it's possible. However, both HDD need to support UltraDMA.
Q. Is it possible to copy a HDD format other than Windows or Macintosh?
A. Yes, it's possible. Disk Jockey copy mode does a sector-to-sector copy, hence is independent of the operating system format.
Q. Does the copied-to HDD need to be formatted first?
A. No, it does not have to be pre-formatted. Even if it were formatted, the copy function overwrites the HDD.
Q. During the copy mode, is it possible to assign a different partition to the copied-to HDD?
A. No, unfortunately this is not possible. The copy function does a sector-to-sector copy, hence it writes the copied-to HDD with identical information.
Q. If the copied-from HDD has a bad sector, is it still possible to continue the copy operation?
A. No, it's not. The Disk Jockey does not have a sector-skip function; hence if there is a problem reading a particular sector from the copied-from HDD, the copy operation ceases, and reports an error.
Q. How long does the copy operation take?
A. It depends on the capacity of the copied-from and the copied-to HDD.
In our testing, a 40GB HDD was copied in approximately 20 minutes.
Q. When copying HDD's, what happens to the software license?
A. The Disk Jockey is a tool to help duplicate the HDD. Please check with the software manufacturer(s) regarding licensing issues.
