Mac doesn't read the drive. Time Machine reads 'delayed' then 'failed' because it can't read drive. Won't backup. Drive doesn't show up on screen.

The disk was mounting intermittently. Then I messed around with the firewire and noticed that if I pushed it a certain way, the disk would mount. So I got out the USB cable and power cable that came with the LaCie and plugged that in. Problem solved. Mounted instantly, backed up with Time Machine perfectly. So, check your connection. I am going to contact LaCie and get another Firewire cable as that is what I paid for, but in the meantime the USB will cover me.

- Open the disk utility application found in the applications folder, then open the utilities folder

- See if it detects the LaCie drive by looking on the right hand side where it lists all the available drives including your optical drive

- If it is just greyed out you might only need to re-format the drive or possibly repair the disk.

- If it does not appear in this list the drive has most likely failed and is not economically repairable

My Brother PE770 won't read my USB

USB thumb drives can begin to have problems with their formatting over time. Try taking off all your files and formatting it with a PC. I have a Mac and sometimes devices do not like the USB drive because the Mac has place some 'hidden' files on it. Your software may ask if you want any files erased on the thumb drive before it write the new files on it. Answer yes which will reformat the USB drive.

I have a 320 gb acclaim portable hard drive. My mac doesn't read it, the first time I plugged it the lap asked me if I wished to format it and I said yes. Now it doesn't read it, what can I

You formatted the hard drive on your laptop in NTFS and the MAC cannot read and write to this formatted NTFS hard drive.
THE FIX
Format the hard drive using your laptop BUT this time format it in FAT32.
The MAC can read and write to a FAT32 formatted hard disk, so now you can exchange data between the MAC and the Windows laptop.

There is nothing you can do to fix the hard drive except to replace it when it fails.

I recently bought a Scosche Digital FM Transmitter Model FMTD8/FMTD8R. I loaded my 8GB San-disk flash drive with music but the transmitter won't read it.. doesn't even detect the flash drive being...

wma files won't be read, only mp3 files, in my experience. My 512 mb SD card works, but it won't read my 8 gb SDHC card. I suspect it can't manage SDHC (high capacity) cards. I haven't tested yet, because as it turns out, neither can my computer... I think I'll fall back to a flash drive.

Hi! I inserted a burned dvd r into my Mac but it's not reading it. The message You've inserted a blank CD pops out. I tried using a PC but it can't open it either, it says there's an error...

there are a few reasons why

1.) the formatting of the disk may be formatter for a PC and NOT a MAC
2.) after burning, this dvd was never "closed"
3.) You burned a coaster

good luck

Hi, I bought a Seagate GoFlex a couple of days ago and successfully backed up my Mac at home. However, when I went to use the GoFlex on my PC at university, the PC was not reading the goflex. Thanks.

Did you reformat the FreeAgent drive when you backed up the Mac? If you use Time Machine or other backup software for the Mac, you had to reformat the drive. If you want the PC to read the disc, it must be formatted in a FAT32 or NTFS file system. The Mac OS formats discs in the HFS+ (extended hard drive format) system.

Unfortunately, if you reformat the disc to a Windows compatible format, you will lose your current backup. The drive will be as a large media transfer disc but not for the backup images. This site, http://www.cs.ubc.ca/~pcarbo/macnexstar.html , has information on splitting the hard drive into two partitions, one HFS+ and one FAT32. Then you could have your backup on one part of the GoFlex and still transfer files from the Mac to the PC and vice versa.

I hope this helps.

I was able to use my Hitachi xl 1000 external hard drive on my computer and I wanted to be able to use it for my Macbook Pro as well but as soon as I used it for Time Machine Backup I wasn't able to use it...

If the MAC formats the external hard drive then the desktop cannot see any files on the hard disk even though it detects the external hard drive.
If you format the external hard drive using the Desktop computer and format it in FAT32 then the MAC can read and write to this hard drive and the desktop PC can also read and write to the external hard drive.
MAC computers can read and write on PC formatted disks but not the other way around.
