XCOPY - copying data from master to slave

Question: XCOPY - copying data from master to slave

Hi guys:

Have an HP Pavilion with a 4 GB master hard drive. Just installed a Maxtor 20 GB as slave (formatted and everything - works fine). I'd like to copy the contents of the master to the slave to use the new 20 GB as master (and use the 4 GB elsewhere). I inserted my boot disk and at the DOS prompt typed in XCOPY /? and keep getting an error message. Any ideas? It keeps telling me "CDR101: Not ready reading drive F: Abort/Retry/Fail" My master drive is C and my slave is D.

Thanks for your help!!

Preferred Solution: XCOPY - copying data from master to slave

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: XCOPY - copying data from master to slave

not sure about the error message

why not use maxtors software to copy the drives, it's free to download or if you got the installation disk with the drive you already have it. Part of maxblast
EZ-Copy lets you make an exact duplicate of your existing hard drive

Or you could download ezdrive from here in the utilities section

How easy is it for me to set up a second HD in my computer, so as to copy some files across from another?

IE: Once i've connected one as a slave & the other the master, how in dos do i get to see which drive is labelled what?
Is it so straight forward as to just connecting the second drive, turning on PC, going into dos & saying "copy these files to here"?

ANY help greatly appreciated please!

Thank you.

Hello again,
My 120g HD (master) is not acting right for the last couple days (revving like it's stuck in low-gear) and I'm afraid it will only get worse.

My HP came with XP Pro pre-installed (3+yrs now) & have no disk, and while I of course have a "work around" for this part of the problem - I'd just as soon NOT go through the endless updates, etc.

My OS, book keeping (QB), mucho software, etc, is all here in a nice neat compartment - updated and configured exactly as I'd have it...and I would like to keep it that way.

I have a 250g (SATA) slaved on a separate controller (obviously) used primarily for vid/storage and mostly empty, but I'm not sure if this will help me at all.
Also my 120 is "D:\" and my 250 is "C:\ " ...that's right - you heard me...long story.

Is it possible to take the whole she-bang and plop it on another drive and still have it function? Am I an idiot?

Yes, I searched this and didn't find a close enough scenario for my comfort.
Yes, I recognize this might potentially be categorized as an XP query.
and Yes, I really am grateful to you for taking the time to school me on this one.

Answer:My master HD (ide) may be dying...can I move the data to slave (sata)?

You ought to be able to drag the entire content of your 120 gb hard drive onto your 250 gb hard drive without any problems... I can't say for certain, but I think it wouldn't have any problems.

I re-installed W XP on the master hard and the slave hard isn't no more recognized and when I try to access it, it's asking me if I want to format it.
With the first W XP (before to re-install it), the slave had the letter E:/ and the DVD the letter D:/. After I re-install it, they switched the letters, the slave has now the letter D (I can change it in COMPUTER MANAGEMENT) and the DVD has the letter D:/.

I moved the slave hard on another computer, also as slave, and it's recognized but it's asking me to format it. What happened and is it possible somehow to recuperate the data I had on it? It was a new hard drive and unfortunately I moved on it all my documents, before re-installing W XP.

When I re-install the new system, I installed it on the same hard drive, even in the same folder!! The rest of the files on the primary hard are intact... but all the data on the slave drive are gone... can anybodey help me?

Thank you!!!

I bought a new hardrive 6 months ago and installed it as the slave. I've been having tons of problems with that configuration, and want to change the newer/bigger hardrive (current slave) to master, and the older/smaller hardrive (current master) to slave. Do I need to completely reformat both hardrives? Is there a way to do it without losing all of my data (or having to back it up) and having to reinstall every program I have? I'm guessing that will be necessary, but wanted to check before I started. Thanks! Ryan

I'm having a bit of an issue with xcopy when using it to copy data to a share on a Network Attached Storage (NAS) device.Not that I thought it could be a problem, but you'll spot that the interesting point here is that the xcopy can not be run to copy from an external (network) source to an internal hdd; instead it's copying to an external (network) source from an internal hdd.The issue.... well, the /d switch seems to be totally ignored in the following xcopy:xcopy e:\www\htdocs\*.* /S /T /E /Y /D /C l:\www\htdocs\*.*xcopy e:\www\htdocs\*.* /S /Y /D /C l:\www\htdocs\*.*Where e:\ is a local hdd and l:\ is mapped to a share on the NAS.Instead of copying to the NAS only those files that have been modified, on every occasion this xcopy command copies everything. I've never experienced this issue when the xcopy command is run to copy from the network to the local hdd.You'll note that I'm not taking in to account the achive bit here. This is for reasons similar to that explained in an article that'll you'll find if you click here.Any revelations of similar experiences and workarounds would be much appreciated. :-)

Question: Master or slave ??

I am installing a second hard drive on my system (win98, PIII, wd20gig, cdr and cd). This second drive is mostly for backup but also for extra storage. Right now the wd20 gig is partitoned into C (this is what I would be backing up) and D(excess storage).

Question is should I put the new drive on the same ide cable as a slave to the wd(leaving the cd and cdr on the second ide cable) or should I put the new drive on a second ide cable as master with the cdr as slave(and put the cd as slave on ide#1)??
I have heard that if you're planning on copying between drives, you should not put them on the same ide cable.

Any ideas would be welcome.

Question: Master or Slave

I have a Zip Drive and a CD Burner connected to one IDE cable. I have a CD/DVD Rom and my hard drive connected to one IDE cable. I have a floppy drive connected via it's own cable. The Question is, how should they be set as far as Master or Slave or does it matter?

Answer:Master or Slave

Yeah it does matter quit a bit.

You must make the hard drive the primary master. Then you have a choice as to which way round you set the rest up, depending on how you are going to use the CD-RW.

If you are going to copy lots of CDs direct from the DVD to the CD-RW, I would make the DVD slave to the HDD, the CD-RW the secondary master, and the Zip the secondary slave.

If you are going to create mostly data Cds or copy CDs to the hard drive first before burning them to CD-RW I would make the Zip the primary slave, and the CD-RW secondary master and DVD its slave.

Third option is if you will use the DVD more than the CD-RW. Make it the secondary master and the CD-RW its slave.

The reasons for all of this are all to do with data throughput speeds through the IDE controllers.

Hi folks, A quick question. How do you play games on the slave drive which are only compatable with win 98 FAT 32 because by default only the master drive boots up with win xp NTFS when windows starts up. I have tried playing the games on 98 but they either crash or don't start up well or tend to stegger.

Answer:Win XP (Master) and win 98(Slave)

click here OSL2000 - An Advanced Multi Boot Manager.Install the boot manager while booted to the WIN XP disk, restart the machine and should then have the option to boot to either HDD/OS. Of course, the win 98 doesn't recognize the Win XP drive because it is NTFS.

Question: Master & Slave

Last night I installed a new graphics card, this card needs an extra PCI power cable, which was at the back of all the other cable, so I had to unplug everything from the PSU.
On replugging everything in, I eventually got everything working again, but on checking the BIOS settiings, I seem to have made by two DVD Drives by Primary Master IDE & Primary Slave IDE devices, my two hard discs (C: & D: have become SATA 1 & SATA 2.
Eventually I managed to get everything to work, by making my Hard Disk my primary boot disc, but I`m a bit confuddled....
How did my two dvd:ram discs become the Primary Slave & Master, I cant remember the original settings of the BIOS, so I dont know if that is how it was set up in the first place, would this have happened when I plugged everything back into the PSU?, and indeed, does it matter, as my boot up is much quicker than before, I have everything working (I think), and my new graphics card (MSI GTX560I) is 30% faster and runs at half the temperature of my previous card (XTX 8800GT XXX Alpha Dog), which ran at very high temps and kept falling over.
What I think Im asking for is re-assurance, I think quite a few people have had the feeling that something isnt quite right, or, why have I got a screw left over feeling.....
Many thanks in advance.

Hi all i have an exisiting creative cd-rom 52x, and i just got a yamaha 20 10 40 cd-rw.

There really should not be a difference. Some cdrw's have to be master to work correctly, I've even seen a few that would not work with any other IDE devices on the cable. I would try it as slave, if it works, great, if not you can rearrange your existing stuff

Answer:master slave??

Welcome, khayoh

You may be a bit confused. The CDRW will either be the master OR the slave, depending on whether you have it on the same ribbon with another device, like your hard drive, or a CDROM drive, etc. There is a jumper setting on the back that you will move accordingly.
Here is a duplicate thread which basically is a two part problem....

Question: Master/Slave

I have a cdrw and cdrom drive, internal zip and hard drive. What confiugration of master/slave will give me the best performance. (the hard drive is udma66)


I'm sure it matters really, but I would probably put the two ROMs on one IDE cable and the HDD and Inter. Zip on the other. However, if the Zip is not an IDE device (which I assume it probably is) then I'd leave the HDD on an IDE cable by itself with the two ROM's together on the other while the Zip (if it isn't an IDE device) would connect by means of a regular floppy drive cable. Hope I helped, if just a little

By the way as far as the master and slave bit I'd go for the CDWR and HDD at the ends of their respectful cables and being the masters while the Zip and CDROM would be slaves.

This will show you jumper settings but i highly doubt this has anything to do with issue.
Could be a bad drive there though. Also could be a memory corruption issue.
I would run hard disk utilities available at every hard drive mfgr site for download and to check system memory. That downloads a program that installs to a floppy disk you boot up to to check memory and you need to run at least 4 complete tests.

Question: Master/Slave HD's

Hi I have a dell optiplex gx280 (I know poor me) lol. I have 2 HD's installed now the first being the 160GB WD SATA, and the 2nd is my older Maxtor 120Gb 7200rpm. I have the Maxtor set as slave off of my DVD/RW which is the master. Both drives show up fine although my boot times are incredibly slow now.. not sure why but the DVD/RW is set as master via jumpers and the Maxtor has no jumpers which is the slave setting for that HD.

My question is even though the Maxtor is a slave drive is there anyway to make it my main boot drive meaning winxp is installed on the slave and the Sata is used for games etc.. I read somewhere it's possible but that winxp will still put the core boot files on C:\ regardless if you install on the slave.

Also performance wise does this make sense? My thought is the Sata is a faster HD overall so for gaming it seems logical to use that whereas I don't do a lot of heavy system processing ie autocad etc and can deal with running the OS on the slower HD.

Thank for your time, whoever may respond to this.


Ps. I don't believe there's anyway to set the sata as a slave as the IDE cable has to support both my DVD/RW and HD and there's not much room to change those as the cables limit it.

Question: Master/Slave

This is fairly new to me (setting Master/Slave) and I'm still not sure I have it straight.

Let me see if I can put this clearly and simply. This is a computer my daughter is using, that was given to me 1 1/2 years ago. At the time it had 2 hd in it, but I found this confusing (I reinstalled WIN 98) so I took one out.

The one left was MASTER (hd) and they both had been on one ribbon cable coming from the mb.

The CD ROM (at that time) didn't work right, sometimes would work (with bought CDs) but wouldn't with home made ones. We thought it was an old, slow one.

Recently I gave someone a CD ROM drive I had (not new, but worked last I knew) to put in that pc. Saying to make sure the jumpers were set the same as the old one (which is MASTER) He did, and the CD ROM drive doesn't work, and seems to be doing the same as the previous one. Power comes on, it spins, but doesn't open and freezes.

This indicates (to me) that it's not the drive that was (and this one, also, in the same way) broken, but the settings.

I haven't done anything yet, just looked inside and it looks like the CD ROM is on it's own (separate) ribbon cable from the mb. if the person who put it in did set the jumpers to MASTER (like I said- to match the old one) and it's doing the same thing, this might mean the settings (like in the BIOS) aren't right to go with this?

Since I'm still not experienced in clear about settings, I thought I'd makie sure I ... Read more


It matters little where you put the CD-ROM, but it is the usual practice, and there are some performance benefits, to using the secondary master connection before using the primary slave. In other words, you have it right if the jumper is set correctly.

What you want to look for in the BIOS is whether both IDE channels are enabled. Some machines have the second channel inactivated when they leave the factory since there is nothing connected to it.

Also, in Device Manager, check your IDE controller settings. It may be set to "Default". That is OK, but changing it to "Both" will insure that the second channel is active.

Question: IDE Master/Slave

Can anybody explain me what is master and slave configuration in IDE card???

Answer:IDE Master/Slave

Generally, one IDE channel will support two drives (HD, CD-ROM, etc), the master/slave is to differentiate between the two drives, so the BIOS knows which is which. Generally, if you have two drives, you want them on separate channels (IDE1, IDE2). When you have two drives one one IDE channel, you will take a slight performance hit, therefore, it is recommended that you put your hard drive as master on channel one, the Optical drives as master/slave on channel two.

Question: Master and Slave

In the event of a presence of a ribbon hard drive and a "new style" hard drive, which one will take precident as the master and which one will become the slave? Will they both want to be master and fight for it?

Is it recomended a system have one of each? Is this a bad idea?

Answer:Master and Slave

You set the boot order in the BIOS. The drives 'fighting' are much like your floppy drive fighting your hard drive back in the day.. It didn't, you set whether it looked for the floppy to boot or the hd first. Same thing happens with SATA and PATA. If you pick your PATA drives in the BIOS to boot first, then same rules as always apply with Master and Slave, if you pick SATA it boots off the SATA drive you select.

Hi, i've been using Win xp for about 5 years now and am slowly getting used to it.But there is one thing i cannot get going despite numerous attempts--i have 2 different internal hard drives--the one that came with the pc and a newer one i bought. i can use either one on its own but can't use both together in a master slave combo--i googled how to set the 2 HDs in the pc and move the jumpers about to make one drive master and one slave etc, connect them both to that cable and a power connection to both etc, with pc off---but when i try to then start pc --nothing happens--its like the pc is dead.      I have noted probs when using either one hard disc--eg pc won't shut down and occas won't reboot---on the rare occas it does shut down it takes numerous attempts to get it started again--it usually makes some bad beeps and then crashes 1 or 2 secs after i hit power on--and often doesn't even beep at all.     1st hdd is--a Maxtor 3.5 series DiamondMax 10  --250GB PATA133     2nd hdd(one in at present is a Seagate Barracuda 7200.7  --120GB     i think both are IDE/ATA type but not sure. one may be SATA --does that matter? Below is a Belarc scan of my pc for your info:          Operating System   System Model Windows XP Home Edition Service Pack 2 (build 2600)   ASUSTeK Computer INC.

Question: Master or Slave ?


Could anyone clarify this for me please.

I have a CD burner as my master and a DVD burner as a slave.

I do most of my burning onto DVD so should i jiggle the ribbons and jumpers about to make the DVD burner the Master ?

I burn a lot of avi and mpeg file formats and i get 'some' lip sync problems, not always but often, I have done as asked about closing all system tray apps and doing a defrag etc before burning and i still get the odd issue so,, i was reading a thread here about someone elses burning problems and they too had their DVD burner as a slave !!!! I wondered if there was a point to this master / slave option.

Thanks for any replies

Answer:Master or Slave ?


The point is that every master can stand alone. If you have a single drive on a ribbon cable that drive must be a master, or otherwise a master can stand alone. If you have two drives on a cable, there must be a master and a slave, or every master must have a slave in this case.

Therefore, it really doesn't matter a lot which is which for practical usage purposes, although my personal preference is the set the one I use the most as Master and if another is on that ribbon cable, it is my slave.

Once set, you don't need to mess with them. I also suspect that any problems you are having might have more to do with the drive or driver than with the master/slave configuration.

Don't forget, the master must always be on the end of the ribbon cable and the slave must be in the middle of the ribbon cable.

Note: Just wanted to mention that WD hard drives are slightly different in their configuration. If you have a WD hard drive and it is alone on the ribbon cable, take all jumpers off and put it on the end of the ribbon cable.

How to reformat it is that the question? Usually you can do that during the windows install (2000, XP) There will be a partition manager you can choose where to nstall windows on and you can move partitions around then it will format the one windows goes on. After windows is installed you can format the other one using explorer right click menu.

Answer:CD set to Master / Slave

Your Hard drive should be connected to IDE1 and your CD to IDE2. Both of these connectors have 40 pins. The floppy drive connects to the smaller connector which has 36 pins. Since your Hard drive and CD are the only devices on each of IDE1 and IDE2 then they should both be set to Master. If your IDE ribbon cables have more than 1 connector then a master device connects to the one at the end of the cable.

My question is simple. During my last reformat (2weeks ago) I decided to put my operating system and program files etc on a 10gb hdd and keep my 80gb as storage. After setting my entire system up I realised the 10gb was only 5400RPM but didnt think much of it. As it turns out it has slowed my pc down a lot so I want to swap the contents of the drives around, so that everything that is on my master will be put onto slave. I tried simply copying it but I got the "file is in use" error. A friend told me about Norton Ghost but I thought there mustve been an easier way. I concidered booting into safe mode and then copying across but assumed that wouldnt work either. There is enough space on the 80GB one to store the master drive in its entirity. All I need to know is how to copy it across.

My Motherboard's main Hard Disk is SATA.. i wanted to connect an IDE hard disk to it.. how do i set it up?

Master = ?
Slave = ?

thanks for the help in advance..

Answer:Master + Slave

Master and Slave are only applicable to the controller you are connecting the ribbon cable to. It doesn't affect the motherboard.
So say for instance you had two IDE plugs and four PATA harddrives. You could conned two to each connection right? Yes, and in each you will have one Master and one Slave. SATA doesnt need to know how the other controllers do their thing. So:

PATA Controller > Master > Slave (1st and 2nd)
PATA Controller > Master > Slave (3rd and 4th)
PATA Controller > Master (fifth hdd) / or Slave (doesn't matter as Gulo notes)
SATA Controller > SATA drive (sixth)
SATA Controller > SATA drive (seventh)

My old computer had windows xp home edition. The mother board went out, I finally got a computer to put my hard drive in. As a master it will not acknowledge windows. As a slave, it will not let me into my documents and settings folder. I believe because I had my computer password protected.

This is how I see it. Because part of windows is embedded into the bios and the cmos, that is why it will not fully load window while being connected to another motherboard. Now I know a bit about DOS And the Registry, so I imagine that is were I will have to change things. Also I had a slave drive along with this master that is now the slave. Lol anyway the in slaved one, shows no files when I hook it to the master I now have. This one totally baffles me, cause when I check it's properties, it shows it's full.

Your teacher's lecture is a bit flawed. In my opinion I would not refer to a group of computers as slaves. However if it is technically and logically sound, I still would not use that terminology. I would prefer to use the terminology client/server or user/administrator. these are the most common uses:- In a client-server relation, the client is the master, and the server is the slave.- In database replication, the master database is regarded as the authoritative source, and the slave databases are synchronized to it.- Peripherals connected to a bus in a computer system.In true technology standings a computer that can access and control other computers would be the "administrator" while the student's computers will be the "clients" or "users"The computer belongs to the school, then there is no way to stop him from accessing it and this website condones any act that is made to bypass any system security. Please do not ask questions about bypassing ANY type of security.

I seem to have a problem with a slave drive of mine. Whenever I insert it into the slave slot, it works as a slave, the first time. However, if I keep it connected and boot a second time, it boots from the slave drive(win98). Everything looks fine in my BIOS, I think it may be a conflict between the two OS's(XP&98). I make sure that the jumpers on the drives are properly set. The only solution I know of to solve the problem permanently is to reverse the positions of the drives(master in slave, vice-versa). But, I hate having it set up like that because it's not proper. I don't know if I'm willing to erase windows98 off the secondary drive though.

Answer:Chaning Old Master HD to New Slave HD

All you need to do is connect the old drive to the empty connector on the cable the new one is attached to, set the jumpers so the new drive is master and the old drive is slave(or you can use cable select jumper settings if you prefer) Then mount the drive.
Refer to the Drive manufacturers' sites for jumper settings if they aren't printed on the labels.

I'd also suggest partitioning the old drive, using Partition Magic or something else that will allow you to do it without destroying the data, then move the data you want to keep onto partitions away from where the old system partition is. Then Format the old system partition. I also recommend partitioning the new drive if they didn't do it for you.

Hello, everyone..

I searched through the older threads, but found nothing similar to this..

My problem is with a WD800JB.. Kept it in my puter as a slave for several months, then gave it to a friend.. Now, the thing is it works flawlessly as a slave, but i can't get it to work as a Master.. For some reason, the puter can't see it as a Master (same puter i used it on as slave).. BIOS detects it, but i get the "Disk boot error" after the quick POST..

Tried booting from the CD, but the WIN XP setup wouldn't recognise it either.. (known good disc, which still serves me well).. I guess i could try a Linux boot, but i'm still a newbie at that, and i don't think i'd know where to begin with the check..

The HD was originally Master on my puter, so it USED to work..

Please help, i wanna help my friend (his current Master drive is a 10GB drive which is kinda acting up)..

Thanks in advance,

PS: Before you ask, i know how to set the jumpers, and how to set it in BIOS, so that's not the problem.. Haven't tried WDDiag yet, i'm not sure the "0-fill" would do anything..

I have installed a dvd player and hooked my cd burner on the same cable. I want to hook my cd rom back up as well, so I hooked it on to the same cable that my hard drive is on and I keep getting an error message as follows: Primary IDE channel no 80 conductor cable installed. Please advise.

Answer:master/slave issue... I think

I have a Dell XPS, that came with a 120 gig SATA Seagate Barracuda, and today i bought a 300 gig ATA Maxtor.

At this point i am stumped, becuase i have the SATA drive as the master, becuase that has the OS on it, which is Win XP Pro.

The computer doesnt even see the new hard drive, becuase there is no master or slave ATA to begin with.

what i was wondering was if there is a way to make it so that i can have the 120 gig SATA be the master, and the 300 gig ATA be the slave.

I tried to hook up the slave connection of the ATA to the new drive, but it didnt work becuase there was no master. so then i hooked up the master connection, and went into settings, and changed my main drive to the new 300 gig. This didnt work, the computer wouldnt even boot up. im guessing that this occured because there is no OS on the new drive.

The only solution that i can think of is to put the settings to where the new 300 gig is the main drive, then boot up the windows XP Pro installation CD, and install the OS on the new drive, but i would REALLY like to avoid this.

thank you VERY much!


Answer:SATA Master With ATA Slave?

Welcome to TechSpot, Makani

Well, SATA doesn't have masters or slaves, just one drive per channel.

You need to set the PATA drive as a master, and change BIOS boot order to boot from SATA first.
